Corn phytotoxicity solution

Corn is one of the main grains in China, weeds will affect the growth and development of corn, so many farmers will use herbicides, but improper use of herbicides will cause drug damage to corn and lead to a reduction in yield. So what should we do after the drug damage occurs in corn? Let's take a look.

1. Soil treatment

Because of the drug damage caused by excessive dose of herbicides, the methods of middle ploughing, continuous irrigation and repeated washing can be used to alleviate the drug damage. Combined with watering, certain lime powder and neutralized acid herbicides can be applied to wash and discharge the residues in time, reduce the residues in the soil, strengthen the field management and enhance the resistance of corn.

2. Strengthen the field management

For the fields with drug damage, we should strengthen field management, combined with watering, increase the application of rotten farm manure, urea and other fertilizers, promote root development and regeneration, restore the physiological function of corn, and promote the healthy growth of crops. reduce the harm of chemicals to crops. Strengthen mid-ploughing and loose soil, break soil consolidation, enhance soil permeability, increase soil temperature, promote beneficial microbial activities, speed up the decomposition of nutrients, enhance root absorption capacity, promote plant growth and development, and reduce drug damage losses. 1% 2% urea solution or 0.3% potassium dihydrogen phosphate solution can also be foliar sprayed.

3. Spraying growth regulators

Plant growth regulators can reduce the growth and development of corn has an excellent stimulating effect, can promote crop growth through zinc, iron, aluminum and other micro-fertilizers, effectively reduce drug damage, the commonly used plant growth agents are gibberellic acid, brassinolide vinegar, compound nitrophenol sodium and so on. In addition, antidotes can be used to reduce chemical toxicity, such as mixing seeds with tea, which can protect corn from herbicides such as Acetochlor, butachlor, alachlor and so on.

4. Replanting and replanting

For the fields with serious drug damage, we should not only find out the causes of the drug damage, but also take targeted remedial measures. If the serious damage cannot be remedied, we should replant or replant in time to reduce the loss.

The above introduction of corn drug damage solutions, hope to help you, want to know more related knowledge, please pay attention to us.
