What about crop damage?

When planting crops, a small amount of pesticides will be sprayed because of a variety of diseases and insect pests, and improper use of pesticides will produce a variety of drug damage, then how to do crop drug damage?

1. Spray clear water

If this situation is due to the drug damage caused by the spray solution on the leaves and plants, if it is found in time that the liquid has not completely penetrated into the plant, the damaged plant can be quickly sprayed with a large amount of water for 2-3 times in a row. Wash off the drugs on the surface of the plant as far as possible, which can alleviate the sustainable development of drug damage. At the same time, it is suggested that 0.2% alkali surface should be added to the sprayed water. As most pesticides are acidic at present, neutralization reactions will occur when they encounter alkaline substances and reduce their efficacy, so they can speed up the decomposition of chemicals and reduce the drug damage of crops.

2. Gibberellin plus sugar detoxification

For the symptoms that have caused drug damage, such as yellow leaves and atrophy of crops, we farmers should detoxify multiple damaged crops in time. For example, corn, peanuts due to high concentration of paclobutrazol spray caused excessive inhibition, growth stagnation, we can timely spray gibberellin plus sugar solution, can quickly restore the normal growth of crops. Grape, apple due to copper preparation, Bordeaux solution caused by drug damage, we can spray 0.5% lime water to alleviate the damage to crops.

3. Herbicide damage

Compared with the drug damage of insecticides and fungicides, herbicide damage is the most difficult to alleviate, and the loss can be reduced if it is found in time or with a low degree of drug injury. if it is found that it is not timely or the degree of drug damage is high, it is difficult to restore the normal growth of crops. If herbicide damage is found in crops, it is recommended that we spray gibberellin + indole acetic acid + brassinolide, dilute 500-600 times and spray continuously for 2-3 times, which can have the effect of relief, rejuvenation and immunity. Now there is a kind of plant growth regulator called Bibu, which combines the above three, and the effect is the same.

White sugar or brown sugar can improve the efficacy and enhance the control effect in the prevention and control of crop drug damage, such as our common washing powder, salt and alkali noodles mixed with pesticides can significantly improve the efficacy and the stability of pesticides, and white sugar is rich in various amino acids, which is more conducive to disease prevention. The mixture of white sugar and Bordeaux solution can significantly improve the stability of Bordeaux solution, control grape downy mildew, anthracnose with a little brown sugar can significantly improve the efficacy and improve the commerciality of crops.
