Causes and remedial measures of Drug damage to Wheat

Weeding is carried out in the rain after wheat emergence, but if there is a little carelessness, there may be drug damage, which will seriously affect the growth, development and yield of wheat. So what is the cause of wheat drug damage? How to remedy when drug damage occurs? Let's take a look.

I. causes of drug damage

1. Improper use of drugs

Improper spraying of drugs during the growth of wheat is one of the key factors causing drug damage to wheat. The main purpose of farmers spraying herbicides on wheat is to have a good growth environment for wheat, but once too many drugs are used, it will cause the wheat seedlings to suffer drug damage. The proportion of drugs is not accurate and the drugs are not used according to the dosage, this series of mistakes will lead to the occurrence of drug damage to wheat, which will affect the growth and development of wheat.

2. Environmental factors

The occurrence of drug damage of wheat and environmental factors also have a profound impact. The occurrence of drug damage of wheat is closely related to temperature, humidity and soil. Changeable air temperature is the main factor of drug damage. Low temperature or high temperature can cause drug damage. Wheat growth needs appropriate humidity, once the growth environment is too dry, the drug applied is difficult to play its main role, and increasing the number of drug use will cause frequent drug damage, if the humidity is too low, the drug will continue to spread along with the water. Sufficient drug damage.

3. Improper use of drugs

In the process of spraying drugs, the spraying of drugs is uneven, which makes part of wheat overapplication and some wheat sowing, which is not conducive to its growth and development. Improper use of time will also cause drug damage. Medication is to avoid the booting stage as far as possible, in the use is to pay attention to the cleanliness of the application utensils, once applied, should be cleaned in time, if not washed and re-spraying other drugs, it will also lead to drug damage.

4. Previous drug residues

The drug use of the previous crop is excessive, which will cause drug residues in the subsequent crops during sowing, coupled with the impact of environmental factors, such as low air humidity and poor soil fertility, may cause drug damage. Once affected by drug damage, the germination rate of wheat is very low, at the same time, seedling emergence will be hindered, and the growth and health of wheat will be seriously affected.

II. Remedial measures

After the occurrence of drug damage to wheat, it is necessary to spray the wheat with clear water as soon as it is found. for the damaged parts, spray water for 4-6 times to wash off the drugs on the surface of the leaves and reduce drug residues. Fully irrigate the damaged areas, when there is a large amount of water in the soil, the roots of wheat will absorb a lot of water, resulting in an increase in cell water content, dilution of drugs, and reduce the occurrence of drug damage. When drug damage occurs, the growth is deformed, the leaves turn yellow, and the growth health of wheat is affected. Phosphorus and potassium fertilizer can be applied to make the wheat obtain the elements needed, improve the soil condition and promote the recovery of wheat. If there is serious drug damage to wheat, such as dead seedlings, can not jointing and heading, then the damaged wheat should be removed in time, replanted in time, or planted other crops in time to reduce the loss.

The above is the introduction of the causes and remedial measures of wheat drug damage. I hope I can help you. If you want to know more about it, please follow us.
