Due to the differences in the types of flowers and fruit trees and their stages of growth and development, some common flowers and fruit trees often cause phytotoxicity when using pesticides, light leaves are fallen, and those who are heavy cause plant death. Especially for ornamental plants that are sensitive to pesticides, the correct selection of pesticides is even more important.
Lime-sulfur mixture: It has phytotoxicity to plants such as peach, plum, plum, and pear. If it is used on these plants, it is best to spray in the deciduous season. Do not use it in the growing season or in the fruit and fruit period.
Killing Pinus sylvestris: In the hot season, killing the insects by killing pines has serious phytotoxicity on the pomegranates, which has certain damage to the cruciferous flowers.
Bordeaux mixture: During the growing season, it is sensitive to peaches and plums; when it is less than twice the amount, pears, apricots, and persimmons are susceptible to phytotoxicity. When the amount is higher than the amount, the grapes are susceptible to phytotoxicity.
Dimethoate, omethoate: Kiwifruit is particularly sensitive and is not used; it can cause obvious phytotoxicity to the ornamental plants of the rose family such as plum blossoms, cherry blossoms, prunus triloba, and Begonia esculenta; Dimethoate also harms coral flowers. Very large, if the use of omethoate spray between June and October, often cause the petals to curl up and lose its ornamental value.
Dichlorvos: Dichlorvos have obvious phytotoxicity on ornamental plants such as plum blossoms, cherry blossoms, and peaches, apricots, 20th century pears, and Jingbai pears. Normally, dichlorvos should be replaced with other types of insecticides. Dichlorvos also have varying degrees of phytotoxicity to Rhododendron, Taro, Kiwi, Scorpion, and walnuts. When using pesticides to control pests of these plants, care should be taken to avoid unnecessary losses.
