Due to the different types of flowers, the differences in growth and development stages often cause some common flowers to cause phytotoxicity when using pesticides . Lighter leaves appear, and heavy ones cause plant death, causing great losses. Therefore, for ornamental plants that are sensitive to pesticides, it is especially important to use pesticides correctly. The following is an introduction to the phytotoxicity caused by common pesticides. Dimethoate, Omethoate: Kiwifruit is particularly sensitive and should not be used; it can produce obvious phytotoxicity to Rosaceae ornamental plants such as plum blossom, cherry blossom, eucalyptus, and apricot, and pear; The flower is also very harmful. If it is sprayed with omethoate from June to October, it often causes the petals to shrink and lose their ornamental value. Dichlorvos: Dichlorvos has obvious phytotoxicity to ornamental plants such as plum blossoms, cherry blossoms, peaches, apricots, 20th century pears, and Jingbai pears. Normally, other types of pesticides should be used instead. Dichlorvos also has different degrees of phytotoxicity to Rhododendron, Taro, kiwi, Chinese wolfberry, walnut, etc. When using pesticides to control pests of these plants, they should be very careful to avoid unnecessary losses. Trichlorfon: It has phytotoxicity to cherry blossoms, plum blossoms, etc. Stone sulphur mixture: It has phytotoxicity to plants such as peach, plum, plum, pear, etc. If used on these plants, it is best to spray in the deciduous season, not in the growing season or flowering period. Fenitrothion: the hot season fenitrothion use in pest control, pomegranate has a serious injury, had some damage to the flowers of cruciferous. Bordeaux mixture: Peach and Li sensitive during the growing season; when it is less than the amount, pear, apricot and persimmon are susceptible to phytotoxicity. When the amount is higher than that, the grape is susceptible to phytotoxicity.
