Due to improper or unreasonable use of pesticides by fruit farmers, causing phytotoxicity of fruit trees, the following remedies may be taken:
Spray water on the tree If it is found early, spray the affected plant immediately, and dilute and wash off the pesticide adhering to the foliage and branches.
The spray neutralizes the leaves and can be sprayed with 50% sodium humate (dissolved first with a small amount of water) to form 3000 times solution. After 3 days, the leaves will gradually turn green.
Timely topdressing of fruit trees after timely damage to the fruit trees can make the damaged fruit trees recover as soon as possible. For the phytotoxicity caused by acidic pesticides, some plant ash and quicklime can be applied. For the phytotoxicity caused by alkaline pesticides, the acidity such as ammonium sulfate can be traced. fertilizer. No matter what kind of phytotoxicity, foliar application of 0.3% urea solution plus 0.2% potassium dihydrogen phosphate mixture, once every 15~17 days, even spraying 2~3 times, can alleviate the phytotoxicity.
After cultivating the pine trees, the fruit trees should be loosened (depth 10~15 cm) in time to enhance the recovery ability of the fruit trees.
Moderate pruning After the fruit tree is tainted, it should be trimmed in time, cut off the dead branches, and remove the dead leaves to prevent the spread of the dead part or the disease caused by the disease.
