Instructions for use

Weeds successfully compete with wheat for growing space, nutrients, and moisture. The grain yield depends on the number of weeds per square meter of the field. One weed reduces productivity by 25 to 70 kilograms of grain per hectare. Using herbicides on wheat allows for successful weed control.

What weeds harm wheat crops?

To control weeds, fields are surveyed in the spring to determine the level of infestation. The use of chemical weed killers (herbicides) is considered necessary if there are 10 to 15 annual weeds or 2 to 3 perennial weeds per square meter.

Weeds are divided into monocotyledons and dicotyledons, as well as annual and perennial.

When cultivating field crops, it is necessary to remove from cultivated areas:

ambrosia;
knapweed;
chamomile;
white clover;
field bindweed;
shepherd's purse;
cleavers;
sow thistle;
field thistle;
quinoa;
couch grass.

Wild oat grass and scaly grass are considered the most harmful weeds for wheat. Wild oat grass is an annual plant that infests spring wheat, causing double damage: small seeds end up in the soil, and large grains end up in the seed. Scaly grass is an overwintering biennial that infests winter wheat. At a density of 30 seedlings per square meter, yield losses will reach 30%.

Description of the best products

Herbicides such as 2,4 D and 2M-4X (amine) are affordable, but are ineffective when fields are infested with weeds other than wild oats and broomcorn.

To control crops, herbicides with other compositions are used.

Expert opinion

An agronomist with 12 years of experience. Our best gardening expert.

For example, the use of inexpensive herbicides based on amine salts is recommended in the early stages of organogenesis.

In winter wheat fields with significant infestations of winter weeds (sow thistle, bedstraw, cornflower, and chamomile), use "Starane Premium 330." Granstar is effective for controlling annual and perennial broadleaf weeds in cold spring conditions. Most herbicides are designed to suppress dicotyledonous annual weeds.

Instructions for use

The use of herbicides for treating crops requires compliance with certain rules:

Do not spray in strong winds or before rain.
The optimal air temperature is 16-25 degrees Celsius. When the temperature drops to 8 degrees Celsius, the effectiveness decreases to 0. Cold stress and chemical treatments can lead to reduced yield or even death of wheat seedlings.
Use at the tillering stage of winter crops.

Prepare the working solution according to the manufacturer's instructions, taking into account the expiration date. Working with chemical compounds requires safety precautions: protective clothing, gloves, and respirators.
