Application of herbicides when growing corn
High infestation of corn crops, especially at an early stage of development, can lead to a significant slowdown in growth and an increase in the mass of the root system. To get a good harvest, it is extremely important to carry out timely processing of the crop.

What are herbicides
Corn herbicides are chemicals designed to control unwanted vegetation in crops. They are divided into drugs with continuous and selective effects:
- Continuous action substances are capable of suppressing or destroying all plants in the treated area; they are used in areas free from cultivated plants.
- Substances of selective or selective action only destroys weeds and are completely safe for cultivated crops.
Types of weeds
Weeds, like cultivated plants, are divided into perennial and annual, and also differ in their harmfulness. The most harmful include thistle, all types of thistle, and bindweed. The difficulty of controlling them lies in the fact that after being destroyed by drugs, they have the ability to produce new shoots; moreover, such weeds are late species and often grow after treatment.
As a result, such malicious plants must be fought constantly. Corn is a heat-loving plant, with slow developing seedlings, therefore, it suffers more than others from weeds, because there are also types of weeds such as acorn grass, wild oats, rapeseed and others, which have a huge supply of seeds and belong to the second stage of development of weeds. Therefore, a specialist must choose the optimal herbicide option for treating corn with a prolonged period of action.
Treatment of corn with herbicides
The expansion of corn crops is hampered by low yields and high costs. To achieve maximum output from the field, it is necessary to optimize the process of crop rotation, and since this plant is weakly susceptible to diseases and does not have pests similar to grain crops, it can perfectly rid other plants of diseases (sunflower broomrape).
The most affordable way increase productivity – carefully select seed material and carry out timely weed control in an organized manner using herbicides for corn.
All herbicides that have passed state registration are divided into soil and post-emergence herbicides, which are designed to prevent the emergence of most annual weeds and control perennial weeds. To achieve maximum effectiveness of the drug, you must:
- Careful tillage of the soil to minimize the number of clods
- Maximum reduction of plant residues from the previous harvest
- Strict adherence to the conditions of use - correctly calculated application rate for the treated area, uniform distribution, taking into account weather conditions
- Sowing seeds to the proper depth
One of the most common are herbicides for corn based on 2,4-D amine salt.But their use is advisable with sufficient moisture, since during drought it is impossible to sufficiently control perennial weeds, which will inevitably lead to partial burns of the crop itself and will slow down its development, as well as adversely affect human health. Processing is carried out strictly during the formation of 3-5 leaves.
It is important to remember that this type of herbicide for corn does not contribute to the rapid drying out of harmful plants, but stops their growth and gradual death within 30-40 days. Therefore, if you see green weed growth the next day after treatment, you should not assume that the drug did not work.
Preparations based on clopyralid have proven themselves to be very effective in controlling weeds, especially when mixed with sulfonylureas; they give amazing results.
The most popular herbicides for corn:
- Trimer – control of dicotyledonous weeds.
- Quasar is a post-emergence drug with selective action.
- Aztec is a selective pre-emergence variety.
- Miranda – destruction of weeds directly in the crops themselves.
- Zephyr 300 – for the destruction of thistle and other difficult-to-eradicate weeds.
- Saga is a pre-emergence selective product
- Turbin is a soil preparation for use in crops.
- Triton is an insurance herbicide for corn, designed to control annual and perennial cereal weeds.
Corn is of great importance for humans, it is not for nothing that at one time it received the name “Queen of the Fields”. Its benefits from consumption for food have long been beyond doubt; in addition, its use for animal feed in the form of silage cannot be overestimated.

I love corn very much, I plant a little in my garden, but for some reason it is small and there are only 1 cob on it, rarely 2. I’ll try to apply your advice, maybe it will help.
Good article!
But I would like to note that, as the experience of our agricultural enterprise shows (6 years of experience in growing corn), treatment with herbicides together with fertilizing with urea gives an increase in corn yield much more noticeably than simple chemicals. treatment.
I think it’s worth using, but it’s also important not to spoil the harvest and the land you’re working with, free consultation here
To engage in Agro, you need high-quality preparations and seeds, I found everything on this resource
Growing corn is impossible without the use of crop-appropriate herbicides. I advise modern farmers to look for plant protection products, seeds, fertilizers and more Here
