How to prevent pesticide damage when applying pesticides to flowers

Dimethoate and omethoate are commonly used by farmers, and they can produce very good results on Rosaceae ornamental plants such as plum blossom, cherry blossom, flowering peach, elm-leaved spirea, and Chaenomeles speciosa. 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 has obvious pesticide damage to plum blossom, elm-leaved spirea, and others, so under normal circumstances other insecticides should be used instead. Dichlorvos also causes varying degrees of pesticide damage to rhododendron, Chinese scholar tree, and others.

Trichlorfon causes pesticide damage to cherry blossom, plum blossom, and others.

When fenitrothion is used to kill insects in high-temperature seasons, it causes serious pesticide damage to pomegranate and also causes relatively great pesticide damage to cruciferous flowers. When using chlordimeform, avoid using it on hibiscus and dahlia.

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