Farmer friends should always check the growth of crops 3 days after applying Basic Copper Sulphate pesticides, especially for the fields where herbicides, plant growth regulators, phoxim and isoprene, which are easy to cause phytotoxicity. Careful inspection in order to discover the drug damage early and take emergency measures to remedy it early can reduce the damage caused by the drug damage.
1. Neutralization by spraying: If the phytotoxicity is caused by acid pesticides, some quicklime or grass ash may be sprinkled. Those with stronger phytotoxicity can also be sprayed with 1% bleach powder. For the damage caused by alkaline pesticides, acidic fertilizers such as ammonium sulfate can be added. No matter what kind of phytotoxicity, foliar spraying of 0.1% to 0.3% potassium dihydrogen phosphate solution, or mixed spraying with 0.3% urea solution plus 0.2% potassium dihydrogen phosphate solution, can significantly reduce the loss caused by phytotoxicity.
2. Water spray rinsing: If the leaves and plants cause phytotoxicity after spraying, they can promptly spray the damaged leaves with a large amount of clean water, spray 2-3 times repeatedly, and cultivate the loose soil to promote root development to enhance crops Resilience.
