Pesticides are almost impossible to eliminate, and can only be used with caution in the application process to minimize the occurrence of pesticides. The following are the common phytotoxicity of pesticides. Let's take a look.
Stone sulphur mixture: It has phytotoxicity to plants such as peach, plum, plum, pear, etc. If used on these plants, it is best to spray in the deciduous season, not in the growing season or flowering period.
Killing pine: use chlorpyrifos to kill insects in the hot season, which has serious phytotoxicity to pomegranates, and has certain damage to the flowers of cruciferae.
Bordeaux mixture: Peach and Li sensitive during the growing season; when it is less than the amount, pear, apricot and persimmon are susceptible to phytotoxicity. When the amount is higher than that, the grape is susceptible to phytotoxicity.
Dimethoate, Omethoate: Kiwifruit is particularly sensitive and should not be used; it can produce obvious phytotoxicity to Rosaceae ornamental plants, apricots and pears such as plum blossom, cherry blossom, eucalyptus, and stalked sea bream; The flower is also very harmful. If it is sprayed with omethoate from June to October, it often causes the petals to shrink and lose their ornamental value.
Dichlorvos: Dichlorvos has obvious phytotoxicity to ornamental plants such as plum blossoms, cherry blossoms, peaches, apricots, 20th century pears, and Jingbai pears. Normally, other types of pesticides should be used instead. Dichlorvos also has different degrees of phytotoxicity to Rhododendron, Taro, kiwi, Chinese wolfberry, walnut, etc. When using pesticides to control pests of these plants, they should be very careful to avoid unnecessary losses.
Trichlorfon: It has phytotoxicity to cherry blossoms, plum blossoms, etc.
