Do you know what pesticides are not suitable for use in the growth stage of flowers? Due to the different types of flowers and the differences in growth and development stages, some common flowers often suffer from phytotoxicity when pesticides are used. The light ones appear defoliation, and the heavy ones lead to plant death, resulting in great losses. Therefore, it is particularly important to select pesticides correctly for ornamental plants that are sensitive to pesticides. The following small series tells you that flowers should be used with caution in the following stages of growth:

Stone sulfur mixture: peach, plum, plum, pear and other plants have phytotoxicity, if used on these plants, it is best to spray in the deciduous season, do not use in the growing season or flowering period.

Fenitrothion: In the high temperature season, fenitrothion is used to kill insects, which has serious phytotoxicity to pomegranates and certain damage to cruciferous flowers.

Bordeaux mixture: peach and plum in growing season are sensitive; pear, apricot and persimmon are prone to phytotoxicity when the dosage is lower than double, and grape is prone to phytotoxicity when the dosage is higher than double.

Dimethoate, omethoate: kiwi fruit is particularly sensitive, taboo; plum blossom, flowering plum, flowering crabapple and other rose ornamental plants and apricot, pear, can produce obvious phytotoxicity; dimethoate shrimp clothing flowers, coral flowers are also very harmful, if in 6-10 months using omethoate spray, often causing petals withered roll, lose its ornamental value.

Dichlorvos: Dichlorvos has obvious phytotoxicity to ornamental plants such as plum blossoms and cherry blossoms, as well as peaches, apricots, pears and pears in the 20th century. Under normal circumstances, other kinds of pesticides should be used instead. Dichlorvos also has different degrees of phytotoxicity to rhododendron, steamed bread willow, kiwi fruit, locust tree, walnut, etc., so it should be very careful when using pesticides to control pests of these plants, so as not to cause unnecessary losses.

Trichlorfon: on cherry blossoms, plum blossoms, etc. are phytotoxic.
