Fruit trees are cured by drugs
There are two kinds of acute and chronic pesticide damage to plants. Acute injury is manifested within a few hours to several days after the spraying, such as spots or yellowing, chlorosis, withering, leaf curling, deciduous fruit drop, and shrinking clusters of leaves or fruits. Chronic medicine damage will manifest itself after a long period of time, such as weakening of photosynthesis, delay of flower bud formation and fruit maturation, dwarfing deformity, and deterioration of flavor and color. Once the fruit trees are found to be phytotoxic, take the following steps to rescue them: Spraying potassium permanganate Potassium permanganate is a strong oxidant and has an oxidative decomposition effect on many chemical substances. Spray 6000 times potassium permanganate solution, can effectively alleviate the injury. Rinse most chemical agents with water and wash them out. If the application concentration is too high and cause injury, sprayer can be used to fill the surface with clean water and spray repeatedly on the leaves of the fruit trees to wash off the residual agent on the surface of the leaves. Suspension of similar drugs should minimize the use of pesticides before the injury has been completely eliminated. In particular, similar pesticides should be stopped for use so as not to aggravate the injury. Immediately after the occurrence of phytotoxicity in the fertilized fruit trees, some quick-acting fertilizers should be added in combination with watering, and cultivating loose soil should be carried out to promote the normal growth and development of the fruit trees as soon as possible. At the same time, foliar application of 0.3%-0.5% urea or 0.2%-0.3% potassium dihydrogen phosphate can improve the nutritional status of fruit trees and enhance the absorption capacity of the root system.
