Weed Control Comparative Review: How to Win the Garden War


Gardeners are well aware that the beds are not only an excellent springboard for growing vegetables and berries, but also a real battlefield with weeds, which with regular persistence occupy the best positions. To prevent stubborn parasitic plants from appearing among the seedlings, taking away moisture, beneficial trace elements and sunlight, you should choose the right weed killer that will not harm beneficial crops.

Traditional folk methods

With the beginning of the cultivation of the first garden crops, mankind also encountered weeds, which, to the detriment of the entire surrounding world, developed much more successfully than their cultivated brothers. With the emergence of the problem, the first methods of dealing with harmful plants appeared, which were different in their purpose and execution.

Method # 1 - regular mechanical weeding

This is perhaps the simplest and most familiar way, despite its laboriousness. The main property of weeding is regularity, which means constant binding to the garden. Vigorous swinging with a hoe and even processing with a mower will not give results if you forget about weeding for at least two weeks, moreover, the effectiveness of actions is minimal. Such regulars of the garden, as wild oats and wheatgrass, tenaciously cling to the soil with their rhizomes, which creep around and form a real carpet. Removing some of the rhizomes does not deprive plants of life, but only contributes to their rapid reproduction.

There is a little peasant trick: you should replace the hoe (shovel) with a pitchfork, which does not chop up parts of the plant, but rips them out of the ground entirely. After that, you need to collect the roots and ground parts and take them away from the garden. I would like to note that this procedure takes a lot of time and effort, and in a couple of weeks the weeds will again be thrown among the greens and strawberries. If your dream is to achieve perfectly clean soil cover without a single parasite, get ready to deal with weeds in your garden as a daily activity.

Using a small pitchfork instead of a hoe or shovel for weeding, you can not only free the soil from weeds, but also loosen it at the same time


For weeding the beds, a weed extractor is used along with traditional tools. To remove the plant, simply immerse the extractor in the soil and turn it 180 degrees

Fertilizer can be made from the resulting green mass. Read more in the article: What are the benefits and harms of weeds + how to make fertilizer from them

Method # 2 - using a covering material

To make the ubiquitous herbaceous parasites dark, a dense material that does not allow air and sunlight to pass through is useful. Construction and greenhouse residues are suitable as a protective blanket:

  • linoleum;
  • black film;
  • cardboard;
  • roofing material.

The method of clearing the soil from weeds is simple: cover the desired area of ​​land with an opaque airtight material for 3 or 4 weeks, after which it can be removed. No plant can withstand such conditions, and the roots, stem rudiments and leaves will naturally die off, after which they can be easily removed with an ordinary rake.

Some weeds have taproots that extend far into the depths. Sometimes the length of rhizomes and their processes reaches 1 m or more

The peculiarity of this method is that weed control should take place before sowing or planting vegetable and berry crops, that is, the procedure must be performed as early as possible. In the middle lane, March was recognized as the optimal time for covered works. A pleasant exception is strawberries, which can quite happily coexist with a black film. The beds are closed completely, leaving nests for berry bushes. As a result, the film simultaneously performs a number of functions:

  • attracts the sun's rays;
  • helps to retain moisture in the soil;
  • excludes berry rotting;
  • stops the growth of weeds.

You can also use mulching agrofibre to control weeds. Read about it: https://diz-cafe.com/ozelenenie/ukryvnoj-material-ot-sornyakov.html

The use of black weed film dramatically increases the yield of garden strawberries. Sweet and juicy berries do not touch the ground, therefore they remain whole and healthy

Method # 3 - drip irrigation device

Quite an interesting system of targeted spot irrigation not only saves water remarkably, but also feeds only the necessary vegetable crops. Water flowing out of a water supply system or a large, raised tank moves through pipes and hoses, and then seeps through small holes punctured in places where vegetables are planted. The essence of watering is to saturate only useful plants with moisture, without giving weeds a chance for growth.

With drip irrigation, all the moisture goes to the plant for which it is intended. Dry land around the crop is a guarantee of protection from weeds and the reproduction of harmful insects

Drip irrigation is effectively used both outdoors and in greenhouses, where parasitic plants multiply at a tremendous speed. Of course, it will not be possible to avoid additional weeding, but the number of weeds with dosed point irrigation will decrease several times.

Method # 4 - protection with mulching

Mulching has been used for a long time, and quite different natural and artificial materials are used to create mulch - a crushed mass:

  • fallen leaves;
  • dry grass;
  • compost;
  • straw;
  • shredded film;
  • landscape fabric.

A layer of carefully crushed material 6-7 cm thick is laid around the vegetable crops with a dense carpet. It allows air to pass through, retains moisture, maintains the necessary temperature for optimal root growth, and at the same time serves as an effective barrier to weeds in the garden.

A biological or artificial mulching mixture is evenly distributed throughout the garden, leaving arbitrary nests for the plants, taking into account their size and growth rate

When laying mulch on the ground, you must adhere to a number of rules. If the plants are planted in the autumn, then the protective mass must be added immediately after planting. In early spring, before using mulch, you should check if the ground is warmed up well. If the weeds have already begun to grow, it is necessary to thoroughly weed the soil, and then lay a thick layer of the crushed mass - up to 18 cm.

Chemical attack on weeds

The weedy army has many warriors: wild oats and chamomile, creeping wheatgrass and horse sorrel, tansy and lamb, St. John's wort and succession. But none of these plants can withstand the aggressive chemical attack - spraying with herbicides.

There are a number of means of the so-called systemic action. These include Tornado, Roundup, Graud Bio. They are applied to the visible surfaces of plants - leaves, stems, inflorescences. The poisonous composition is absorbed by the pores of the herbs and gradually accumulates in their roots. A big plus of these funds is absolute safety for the surrounding soil. The land is not polluted, therefore, after herbicide treatment, you can safely plant cultivated plants. The period of exposure to pesticides depends on their composition and the degree of resistance of the weeds, most often 2 weeks are enough to completely clear the area.

Agrokiller equally well destroys not only annuals and perennials, but also shrub-woody shoots. With its help, you can effectively deal with a dangerous and tenacious hogweed, capable of causing extensive burns.

In order not to damage vegetables or berry bushes, a simple tool is used to apply herbicides to weeds - an ordinary paint brush

The main rule when using herbicides is to accurately and accurately apply them only to harmful flowers and herbs, since the poisonous substance equally effectively kills any plants, including berry bushes and vegetables. Due to the total destruction of all living things, the optimal use for herbicides is their spraying in areas far from the beds, but also in need of cleaning: thickets along the fence, grass nests in the furrows, burdock and thistle bushes on the sides of garden paths.

Let's take a closer look at two tools. Roundup is a versatile herbicide that is used to get rid of absolutely any plant. It does not have soil activity, therefore it is used before sowing vegetable crops. If you act according to the instructions, then the product is completely safe for people, animals and the environment. A container with a volume of 1 liter, which is enough for 20m ², costs 1250 rubles.

Often large containers of continuous herbicides (e.g. Roundup) are equipped with a small pump and hose that add convenience and speed to the process.

The second popular remedy is Tornado. On the territory of the garden, it is recommended to use it against weeds such as cattail, creeping wheatgrass, bindweed, thistle, pig, reed. After applying the composition, after about 8-10 days, the plants begin to turn yellow, wither, and after 2.5-3 weeks they finally die. After about 3-4 days, vegetables and berries can be planted on the treated soil. A container with a volume of 1 liter costs 900 rubles.

Tornado herbicide is safe for animals and bees, but poisonous for fish. When using it, contact of the solution with the mucous membrane of the eyes should be avoided.

By learning how to control weeds using various methods and tools, you can increase yields and turn semi-wild garden thickets into a model plot.

When growing garden and horticultural crops, we constantly have to fight against pests, diseases and weeds. Weed control in the garden is carried out by every summer resident, but not always successfully. But if pests and diseases eat the crop for a short period, then weeds parasitize from early spring to late autumn. And the harmfulness of weeds is detected only after the harvest has been harvested. Weed damage is especially noticeable with the systematic use of organic fertilizers. If cultivated plants use nutrients from fertilizers on average by 40%, then weeds by 56-70%. Therefore, fertilizers will not be able to exert their full effect on heavily contaminated soils. Some types of weeds not only absorb nutrients from the soil, but are also able to absorb them with the help of their roots even from the roots of crops, such as creeping wheatgrass, pull phosphorus from fruit trees.

By the appearance of weeds, one can judge how fertile the soil is and its acidity. So, quinoa, odorless chamomile are especially fond of nitrogen. Field jar, field thistle grow better on soils where there is a lot of potassium. It is possible to judge about the high acidity of the soil by such weeds as field horsetail, plantain, sorrel, tricolor violet. And it is impossible to grow a high yield on such soils without liming.

Novice gardeners usually underestimate the damage caused by weeds or simply do not know how to get rid of weeds and how to protect them from them. Weeds not only reduce soil fertility due to the consumption of moisture and nutrients, but also inhibit crops, shading cultivated plants; on weedy crops, the soil temperature decreases by at least 2-4 °. This reduces the activity of soil organisms, slows down the decomposition of organic matter and reduces the amount of nutrients in the soil.

The roots of some weeds emit phytoncides that inhibit the growth and development of cultivated plants. A large number of dangerous species of pests and pathogens develop on weeds, which spread to cultivated plants. For example, ticks and aphids concentrate on sow thistle and field bindweed, cabbage pests breed on cruciferous weeds, the Colorado potato beetle first lives on black nightshade and henbane.

Various soil nematodes that reproduce on the field sow thistle, mari white, cause great harm to vegetable plants.


Weed control

The yield and beauty of flowering plants often depend on what they are mulched with.

We have written extensively about different types of mulching materials. Today we will focus on stone mulch.

Harvested and decided to retire? Wait! First, you should deal with the weeds.

Today we will talk about ways to control burdock - one of the largest weeds on the site.

Why is this nondescript herbaceous annual so dangerous for cultivated plants?


The best weed control

If you are tired of manually controlling weeds, you can use herbicides. And if you use them wisely, without violating the instructions, then their use will not negatively affect the soil and your health.

Consider the most popular in 2020 and probably the best weed killers.

Herbicide, instructions for use

There are herbicides of continuous action - these are those preparations whose action is aimed at destroying all weeds indiscriminately and selectively - the action of such preparations is selective, for example, they can destroy all grass, except for potatoes and tomatoes, etc. This is how far science has gone.

Zenkor

It is a systemic herbicide with a broad spectrum of action against dicotyledonous and cereal weeds in the pre- and post-emergence period of their development. It is used on potatoes, tomatoes, alfalfa and essential oil crops. Active substance: Metribuzin, which is easily absorbed by the roots and seedlings of plants, and also penetrates the leaf surface of the plant.

Zenkor destroys weeds at the time of their germination (with pre-emergence application) or within 10-20 days with post-emergence application.

The advantages of this herbicide:

  • ensures the cleanliness of crops from weeds for a period of 1-2 months or more, depending on weather conditions during the growing season and soil type
  • reliability: proven in the course of widespread use in various soil and climatic zones.

How to use Zencor

On tomatoes... The amount of solution for the treatment of 1 hundred parts of the plot is indicated.

  • Spraying the soil before planting tomato seedlings. Dissolve 10-15 g of Zenkora in 3 liters of water
  • spraying crops in the phase of 2-4 leaves of the culture. 7 g of the drug per 3 l of water
  • spraying weeds 15-20 days after planting seedlings in the ground. 10 g for 3 liters of water.

On potatoes... 3 liters of working solution is enough for spraying 1 weave of a plot.

  • Spraying the soil before potato shoots. 7-14 g Zencora for 3 liters of water.
  • spraying the soil before crop sprouting followed by processing at a leaf height of 5 cm. 5-10 g per 3 l of water
  • spraying plantings with a potato tops height of 5 cm. Dilute 7-8 g in 3 liters of water.

Tornado

It is a universal preparation of continuous action, which serves to destroy all types of weeds, including malicious ones such as wheatgrass, thistle, bindweed and unwanted trees and shrubs.

Active substance: glyphosate (isopropylamine salt).The herbicide is available in containers of 5 ml (ampoule), 50 ml, 100 ml, 1000 ml (bottle).
Tornado drug analogues: Glysol, Glialka, Ground, Roundup, Hurricane, GlITERR.

How Tornado Herbicide Works

It has a systemic effect, penetrates into weeds through leaves and other green parts, and is carried through all organs of the weeds, reaching their root system. The herbicide blocks the synthesis of aromatic amino acids, which leads to damage to growth points and the complete death of aboveground and underground organs. Tornado has no effect on seeds.

Symptoms of the drug's effect on annual weeds become noticeable after 4 - 5 days, on perennials - after 7 - 10, on trees and shrubs and reeds - on the 20-30th day after treatment and appear as yellowing, then drying of the leaves. Further, the death of stems, roots and rhizomes occurs. The complete death of weeds occurs approximately in 3 - 4 weeks after treatment, and of trees and shrubs - in 1 - 2 months. Under unfavorable weather conditions (cold, drought, precipitation), the effect of the herbicide may slow down.

The advantages of this herbicide:

  • high penetrating power
  • the ability to destroy 155 types of weeds
  • ideal for tillage before sowing.

When spraying, you need to ensure that the tornado does not fall on cultivated plants and forest belts. In order to avoid drift of spraying onto crops, it is not recommended to carry out the treatment at a wind speed of more than 5 m / s.

Since this herbicide does not have soil activity, selective herbicides must be used to kill weeds growing from seeds after crop emergence.

How to use Tornado

  • Against annual cereals and dicotyledons, 20-40 ml / 100 sq. m
  • against perennial grasses and dicotyledons - 40-60 ml / 100 sq.m
  • against malicious perennials (field bindweed, pink bitterness, finger pig, field horsetail) - 60-80 ml / 100 sq.m
  • against hydrophytic (water) - 80-100 ml / 100 m2
  • against deciduous trees and shrubs - 40-80 ml / 100 sq.m.

The dosage is influenced by the type of weeds, the stage of development, leafiness, density of the grass stand.

The recommended concentration of the working solution is 1 - 3%. The working solution is prepared immediately before spraying and do not store it. First, the drug is thoroughly mixed in its original packaging, then the required amount of the drug is measured for one filling of the sprayer. Fill the sprayer tank about half with water and pour in the measured amount of herbicide, mix and bring the spray tank to full volume with water. Mix everything thoroughly.

Treatments with the Tornado preparation can be carried out at any positive temperatures both in spring and in autumn.

Processing should be carried out in calm, dry weather and not in the sun. Rain that has passed earlier than 4 hours after spraying can wash away the preparation that has not penetrated the weed leaves and significantly reduce the effectiveness of the herbicide.

Prima

It is a postemergence systemic herbicide designed to control annual and some perennial dicotyledonous weeds in cereals and maize. Affects weeds that have already sprouted by the time of treatment.

It destroys many dicotyledonous weeds, including such malicious and intractable species as: tenacious bedstraw, odorless chamomile, field thistle, yellow thistle and others.

Active substance: 2,4-D (complex 2-ethylhexyl ether) + florasulam.

How Prima herbicide works

It is easily absorbed, and quickly (literally within an hour) spreads over the weed plant, blocking growth processes.

Symptoms of damage (visible) in plants appear 1-3 days after spraying, and their death occurs on 7-14 days. Rain after 1 hour after treatment will no longer affect the effectiveness of the Prima herbicide.

Due to the fact that the half-life of the active substances of this drug is only 14-20 days, it quickly degrades in the soil, without negative consequences for subsequent crops of the crop rotation.

How to apply Prima herbicide

Prepare a working solution immediately before use. To begin with, the drug is thoroughly mixed in its original packaging. The sprayer tank is 1/3 filled with water. Then add the required amount of the drug per 1 filling of the sprayer, mix. Then add water to the full volume of the tank and mix the resulting mixture.

On spring and winter wheat, rye, spring barley.

  • Spraying of crops in the tillering phase of the crop and the early phases of weed growth. Winter crops are processed in spring. The rate of application of the drug is 0.4-0.6 liters. Working fluid consumption - 200-400 l / ha.
  • Spraying of crops in the phase of emergence into the tube (1-2 internodes) of crops and early phases of growth of weeds (taking into account the sensitivity of varieties) in the case of a predominance of tenacious bedstraw if weather conditions did not allow processing ahead of this time. Winter crops are processed in spring. The rate of application of the Herbicide is 0.6 l.

On corn.

  • Spraying of crops in the phase of 3-5 leaves of the crop and the early phases of weed growth. The rate of application of the drug is 0.4-0.6 liters. The consumption of the working solution is 200-400 l / ha.
  • Spraying of crops in the phase of 5-7 leaves of a crop in the case of a predominance of tenacious bedstraw, if weather conditions did not allow processing earlier than this period. The rate of application of the herbicide is 0.5-0.6 liters. Working fluid consumption - 200-400 l / ha.

Gardeners reviews

what is the strongest weed killer

Excellent worker - a remedy against weeds. Acts selectively, only on weeds. Dilute an ampoule of 10 ml in 2-3 liters of water - consumption per 100 sq.m. Destroys annual and perennial cereal weeds (including creeping wheatgrass). Now I will not weed

Tornado helps well, even if it rains a lot and lasts for a long time

What is the best weed killer? so that it is less harmful to health. We bought an abandoned garden, we don't know how to remove all the grass now, digging is not an option at all, the whole earth is permeated with the roots of sow thistle and nettle. We want to have time to plant everything this year, tell me what is the best way to process so that there are no weeds and you could immediately plant vegetables for food, at least potatoes, carrots, cabbage.

I have been using Panther on potatoes for 3 years. Very effective herbicide, kills all weeds, leaves only potatoes. In our climate, rain is not uncommon, and this herbicide is not washed away by rain. Even if you just processed the potatoes and it started raining, then you don't have to worry, the Panther will still act. An excellent product, I recommend it.

very good remedy Propolol. It is a systemic herbicide of a wide spectrum, destroys all weeds in grain crops. But I used it to remove all the weeds (I had a lot of sow thistle) before sowing the lawn. I liked that very little of it is needed, it turns out economically. And so, probably only large farms use it, which sow entire fields. Instructions for the use of the drug Propolol writes the consumption rate of 100 - 120 g / ha, destroys all the main dicotyledonous weeds common in cereal crops, including hard-to-eradicate: chamomile, tenacious bedstraw, pikulnik, sow thistle, etc. Ensures the cleanliness of crops before harvesting, that is for the whole summer.
