Dimethoate and omethoate are often used by farmers, which can produce very good curative effect on rose ornamental plants such as plum blossom, cherry blossom, peach, elm leaf plum, pedicel begonia and so on. Spraying dimethoate from June to October often causes withered petals and shedding leaves, inflorescences and branchlets.

Dichlorvos is obviously harmful to plum blossom, elm leaf plum and so on, so other insecticides should be used instead. Dichlorvos also has different degrees of drug damage to rhododendron and Robinia pseudoacacia.

Trichlorfon is harmful to cherry blossoms, plum blossoms and so on.

Fenitrothion is used to kill insects in high temperature season, which not only has serious drug damage to pomegranate, but also has great drug damage to cruciferous flowers. When using chlordimeform, it should be avoided on hibiscus and dahlia.

In order to prevent pesticide damage, the first is to use other harmless pesticides; the second is to reduce the concentration as far as possible; the third is not to spray under the conditions of high temperature and high humidity.
