Pesticide wrong sneeze rescue
There are two common hazards of pesticides to plants. The first hazard is that there will be spots, withered, curled leaves, fallen leaves and fruit on the leaves or fruits; the performance of the second hazard must wait for a period of time to show, such as photosynthetic. Reduced effects, delayed formation of flower buds and fruit ripening, dwarfing deformity, and deterioration of flavor and color. Once the fruit trees are found to be phytotoxic, the following measures should be taken immediately to rescue them:
Flushing Because many pesticides are not resistant to washing, it is a viable method to flush with clean water if it is sprayed by mistake or if it is sprayed. If the spray density is too high, use a sprayer to fill it with water, and repeatedly rinse the leaves of fruit trees. In order to better remove the residual agent on the surface.
Fertilizer water should be combined with watering to supplement some quick-acting fertilizers, and then cultivating loose soil can promote fruit trees to restore normal growth and development as soon as possible. At the same time, spraying 0.3%~0.5% urea and 0.2%~0.3% potassium dihydrogen phosphate on the foliage can improve the nutritional status of the fruit tree and enhance the root absorption capacity.
Appropriate spraying of potassium permanganate because potassium permanganate is a strong oxidant, with the role of oxidation and decomposition, if sprayed 6000 times potassium permanganate solution, it is also an effective method for the relief of phytotoxicity.
