Which pesticides have a relatively large impact on flowers?

As is well known, many pesticides have a great impact on flowers. Dimethoate and omethoate can cause obvious phytotoxicity to ornamental plants in the Rosaceae family, such as Japanese apricot, cherry blossom, flowering peach, elm-leaved spirea, and flowering quince. When dimethoate is sprayed from June to October, it often causes petals to wither and curl and leaves, inflorescences, and small branches to fall off.

Dichlorvos causes obvious phytotoxicity to Japanese apricot, elm-leaved spirea, and others, so other insecticides should generally be used instead. Dichlorvos also causes varying degrees of phytotoxicity to rhododendrons, Chinese scholar trees, and others.

Trichlorfon causes phytotoxicity to cherry blossoms, Japanese apricots, and others.

When fenitrothion is used to kill insects in the high-temperature season, it causes severe phytotoxicity to pomegranates and also relatively great phytotoxicity to cruciferous flowers. When using chlordimeform, avoid using it on rose of Sharon and dahlias.

To prevent phytotoxicity from pesticides, first, switch to other harmless pesticides; second, reduce the concentration used as much as possible; third, do not spray pesticides under conditions of high temperature and high humidity.
