Dimethoate, omethoate: Plum, cherry, cherry, peach, eucalyptus, paste stems jellyfish, apricot, pear and Other Rosaceae ornamental plants can produce significant phytotoxicity. Dimethoate harms the flower and coral flowers of Aegeritae. If it is sprayed with Dimethoate in June, it often causes the petals to curl up and the leaves, inflorescence and branchlets fall off, losing their ornamental value. Dichlorvos: Dichlorvos have obvious phytotoxicity on ornamentals such as plum blossoms, cherries, peaches, apricots, and leaves, and can often be switched to other types of insecticides. Dichlorvos also have varying degrees of phytotoxicity to Rhododendron, taro, kiwifruit, sorghum, walnuts, and melons. When using pesticides to control the pests of these plants, great care should be taken to avoid unnecessary losses. Trichlorfon: Trichlorfon has phytotoxicity on cherry blossoms, plum blossoms, and Golden Shuai varieties in apples. Lime-sulfur mixture: Lime-sulfur mixture is harmful to peaches, plums, plums, pears and other Rosaceae plants. If lime sulfur is used on these plants, it is best to spray in the deciduous season. Do not use it in the growing season or the flower and fruit period. . Lime sulfur is also harmful to kiwifruit, grapes, cucumbers, and leguminous flowers. Killing Pinus sylvestris: In the high temperature season, killing insects by killing pines will cause severe phytotoxicity to pomegranates, and will also cause greater damage to the cruciferous flowers. Bordeaux mixture: Bordeaux mixture is sensitive to peaches and plums during the growing season. Below the multiple formula, pears, apricots, and persimmons are susceptible to phytotoxicity; above the equal amount formula, grapes are susceptible to phytotoxicity. Songzhi Mixture: Using pine oil mixture in the summer has obvious phytotoxicity to the persimmon, and the spring and summer season has adverse effects on the citrus. Insecticides: Use of insecticides to control flower pests should be avoided on rafts and dahlias. Topozone: Topiramate should be avoided when controlling kiwifruit pests and diseases. Oil Emulsions: Oil emulsions are susceptible to phytotoxicity on certain peach varieties and are best used during the deciduous season. In order to prevent pesticides from causing phytotoxicity to many ornamental plants, the first is to use other pesticides that are highly efficient and non-harmful; second is to minimize the use of concentrations; third is not to spray under high temperature and high humidity conditions, so as to avoid Loss; also pay attention to the rational use of pesticides.
