What should I do if there is drug damage to wheat?

Wheat is a widely cultivated cereal crop, and drugs will inevitably be used to control diseases in the planting process. What if the improper use of wheat causes drug damage?

First, how to do when there is drug damage to wheat?

1. The drug damage caused by fluazolone sulfuron before winter should be poured back to green water and fertilized to promote the normal growth of wheat seedlings as soon as possible, combined with spraying phosphorus and potassium source pool, brassinolide, compound sodium nitrate and so on for 2 times. When the growth of wheat seedlings is seriously inhibited, an appropriate amount of gibberellin can be added.

two。 Drug damage of ethyl fluorocarboxylic ether

Strengthen fertilizer and water management, spray quick-acting fertilizer, if there are dead seedlings in large areas, we should consider replanting as soon as possible.

3. Phenoxy carboxylic acid drug damage

According to the situation of drug damage, brassinolide, gibberellin and naphthylacetic acid were sprayed to restore the normal physiological function of wheat, accelerate cell division and promote root growth.

4. Oxazolidone drug damage

After the occurrence of drug damage, we should spray quick-acting fertilizer and foliar fertilizer as soon as possible, strengthen the management of fertilizer, water and cultivation measures, and consider replanting as soon as possible after a large area of death.

In addition, the following points need to be done:

1. Irrigation and detoxification

When drug damage occurs, irrigation and detoxification must be carried out immediately to drain the poisonous irrigation water in the field. Continuous irrigation with fresh water or lime combined with drainage can be used to neutralize acid herbicides in the field and reduce drug damage. For the drug damage on the plant, spray irrigation or spray water can be used to wash away the residual agents on the toxic plant, which can effectively reduce the drug damage.

two。 Increase fertilizer application

We must strengthen the management of the wheat fields that have been damaged. In fertilization, we should pay attention to the application of Sada organic fertilizer. The organic matter can act as an adsorbent to herbicides and make herbicides lose part of their activity.

3. Timely field inspection and replanting

For the plots that are seriously damaged by drugs, resulting in the death of wheat seedlings or inability to jointing and heading, it is necessary to destroy and replant or replant other crops in time to minimize the drug damage.

4. Use detoxification drugs

Common detoxification drugs such as gibberellin are sprayed evenly with 2 grams of water and 50 kilograms of water per mu to stimulate the growth of wheat seedlings and reduce drug damage.
