Fruit trees are sensitive to certain pesticides , and even in trace amounts, phytotoxicity can occur. Due to the particularity of certain pesticides and the lack of common knowledge of pesticides in some fruit farmers, in the prevention and control of fruit tree pests and diseases, the misuse and abuse of pesticides cause phytotoxicity of fruit trees to occur, so that the damaged fruit trees are light and dead leaves are heavy. The flowers fall and fall, and even the dead branches die. Therefore, it is necessary to understand the pesticides that are contraindicated in fruit trees.
Phosphamine: Peach trees are extremely sensitive and cannot be used.
Trichlorfon, dichlorvos: Kiwi, stone fruit trees are particularly sensitive and cannot be used.
Dimethoate, Omethoate: Kiwifruit is particularly sensitive and should not be used. Citrus, peach, plum, and jujube are sensitive to the drug solution with a dilution factor of less than 1500 times. When using, test should be done first to determine the safe use concentration.
Daofeng San: It can control the diseases of fruit trees such as citrus, but peach and grape are sensitive to this medicine and should be used with caution.
螨克,克螨特: It can cause phytotoxicity when used on pear trees. For the new shoot of citrus, the dilution concentration should not be less than 2000 times.
Arsenic preparations (Tian An, Fumei, etc.): Some varieties of stone fruit, kiwi, citrus and pear are sensitive and should not be used. Persimmon trees should be used after June.
2,4-D Butyl, 2 A 4 Chlorine: All fruit trees are sensitive to both agents and should be banned.
Glyphosate, gram tracer: are all herbicides, all fruit trees are sensitive, can only be used for orientating spray weeding between orchards.
Bordeaux mixture: Peach and plum are sensitive to the growing season and are forbidden to use. When the ratio of Bordeaux liquid lime to copper sulfate is lower than the multiple amount, pear, apricot and persimmon are susceptible to phytotoxicity; when higher than the equivalent amount, berry varieties such as grapes are susceptible to phytotoxicity.
Stone sulfur mixture: young plants of peach, plum, grape, pear and other fruit trees are prone to phytotoxicity, so they cannot be used during the growing season.
