Due to the improper use of pesticides by fruit farmers, the fruit trees should be phytotoxic. According to the specific causes and damage degree of the phytotoxicity, the following remedial measures should be taken to minimize the damage of the fruit trees. Once the water is sprayed, it should be sprayed with water to wash the damaged plants to dilute and wash off the pesticides attached to the leaves and branches to reduce the pesticide content in the tree. The more timely and effective the measure is, the better. When the spray is neutralized and the leaves are whitened, such as phytotoxicity, the granular 50% humate can be used to form 3000 times solution for foliar spray. If the sulphate is caused by the copper sulphate ion in the Bordeaux mixture, a 0.5% to 1% aqueous lime solution can be sprayed to eliminate the phytotoxicity. If the sulphur sulphur mixture produces phytotoxicity, on the basis of water washing, spray 400-500 times of rice vinegar solution to reduce the phytotoxicity; if wrong or excessive use of organophosphate, pyrethroids, aminomethyl esters and other pesticides It can spray 0.5%~1% lime water, washing powder, soapy water, clean water and so on. After the timely application of the fruit trees to the phytotoxicity, the growth is blocked, the growth is weak, and the fertilizer must be applied in time to promote the recovery of the affected fruit trees as soon as possible. If the phytotoxicity is caused by acidic pesticides, some ash, lime, etc. may be applied. For alkaline pesticides causing phytotoxicity, acid fertilizers such as ammonium sulfate may be applied. No matter what kind of phytotoxicity, foliar spray 0.3% urea solution + 0.2% potassium dihydrogen phosphate mixture, or spray with 1000 times liquid plant power 2003, spray once every 15~17 days, even spray 2~3 The times can alleviate the phytotoxicity. When injecting clean water, when controlling pests such as beetles, geyser, and hibiscus moths, when the concentration of the drug is too high to cause phytotoxicity, immediately inject a large amount of water into the trunk of the tree trunk and let it flow outward. Dilute the pesticide. After cultivating the pine and soil trees, it is necessary to timely cultivate the soil in the field (depth 10~15 cm), and artificially cultivate the roots, and increase the application of phosphorus and potassium fertilizers to improve soil permeability and promote root development. Enhance the recovery ability of the fruit tree itself. After the right amount of pruned fruit trees are tainted, it is necessary to pruning in an appropriate amount in time, cutting off the dead branches, and removing the dead leaves to prevent the spread of the dead parts or the infection by the pathogens.
