The damage of pesticides to fruit trees is divided into acute injury and chronic injury. Acute injury is manifested within a few hours to several days after spraying, such as spots, yellowing, chlorosis, withering, leaf rolling, fallen leaves, fruit drop, and shrinking tufts. Chronic injury may take a long time to show, such as weakened photosynthesis, delayed flower bud formation and fruit maturation, small size, deformity, and deterioration of color.
Once fruit trees are found to have been sterilized, the following measures should be taken immediately to rescue them. First, spray potassium permanganate. Potassium permanganate has an oxidative decomposition effect on a variety of chemical substances. Spraying 6000 times potassium permanganate can effectively alleviate the injury. Second, rinse with water. Most chemical agents are not resistant to water erosion. If the pesticide concentration is too high, the nebulizer should be filled with clean water and the fruit tree leaves should be washed repeatedly to flush out the residual chemicals on the surface of the leaves. Third, suspend the use of similar pesticides. Before the phytotoxicity is completely eliminated, reduce the use of pesticides as much as possible, especially if the pesticides of the same type are to be stopped, so as not to aggravate the phytotoxicity. Fourth, pay close attention to fertilization irrigation. After the occurrence of phytotoxicity, fruit trees should be supplemented with water-saving fertilizers and cultivating loose soil. At the same time, 0.3%~0.5% urea and 0.2%~0.3% potassium dihydrogen phosphate should be sprayed on the leaves to improve the nutrient status of fruit trees and enhance root absorption.
