Which pesticides should not be used during the flowering plant growth stage

How much do you know about pesticides that should not be used during the flowering plant growth stage.

As someone who loves growing flowers, do you know which pesticides are unsuitable for use during the growth stage of flowering plants? Because flower species differ and growth and development stages vary, some common flowers often suffer pesticide damage when pesticides are used; in mild cases, leaf drop occurs, and in severe cases, the plants die, causing great losses. Therefore, for ornamental plants that are relatively sensitive to pesticides, correctly choosing pesticides is especially important. Below, the editor tells you that the following types should be used with caution during the growth stage of flowers:

Lime sulfur mixture: It causes pesticide damage to plants such as peach, plum, Japanese apricot, and pear. If it is used on these plants, it is best to spray it during the leaf-drop season, and it must never be used during the growth season or the flowering and fruiting period.

Fenitrothion: Using fenitrothion to kill insects in high-temperature seasons causes severe pesticide damage to pomegranate and does certain harm to flowers of the Brassicaceae family.

Bordeaux mixture: Peach and plum are sensitive during the growth season; when below the dilution multiple, pear, apricot, and persimmon are prone to pesticide damage, and when above the dilution multiple, grape is prone to pesticide damage.

Dimethoate and omethoate: Kiwifruit is especially sensitive and should not be used; they can produce obvious pesticide damage to Rosaceae ornamental plants such as Japanese apricot flower, cherry blossom, Prunus triloba, and Chaenomeles speciosa, as well as apricot and pear; dimethoate is also very harmful to shrimp plant and coral flower. If omethoate is sprayed from June to October, it often causes petals to wither and curl, losing their ornamental value.

Dichlorvos: Dichlorvos causes obvious pesticide damage to ornamental plants such as Japanese apricot flower and cherry blossom, as well as peach, apricot, Twentieth Century pear, and Jingbai pear. Under normal circumstances, other types of insecticides should be used instead. Dichlorvos also causes varying degrees of pesticide damage to rhododendron, Salix matsudana f. umbraculifera, kiwifruit, Chinese scholar tree, and walnut. When using pesticides to control pests on these plants, great caution should be taken to avoid unnecessary losses.

Trichlorfon: It causes pesticide damage to cherry blossom, Japanese apricot flower, and others.
