Flower medication is handled with care

The prevention and control of flower pests and diseases cannot rely solely on certain chemical pesticides. Instead, different pesticides and dosages need to be used according to the actual situation of the flower planting area. The following is a summary of the Chinese pesticide network :
Dimethoate, Omethoate: Plum, cherry, cherry, flower peach, eucalyptus, stalked sea bream, apricot, pear and other Rosaceae ornamental plants can produce obvious phytotoxicity. Lego is also very harmful to the shrimp flower and coral flower of Jujube. If it is sprayed with dimethoate in June, it often causes the petals to shrink, and the leaves, inflorescences and twigs fall off and lose their ornamental value.
Dichlorvos: Dichlorvos has obvious phytotoxicity to ornamental plants such as plum, cherry, peach, apricot, and eucalyptus, and usually the other varieties of insecticide can be used instead. Dichlorvos also has different degrees of phytotoxicity to Rhododendron, Taro, kiwi, Chinese wolfberry, walnut and melon. When using pesticides to control pests in these plants, care should be taken to avoid unnecessary loss.
Rosin mixture: In the summer, the use of rosin mixture has obvious phytotoxicity to persimmon, and it has an adverse effect on citrus in spring and summer.
Trichlorfon: Trichlorfon has phytotoxicity to cherry blossoms, plum blossoms, and golden varieties in apples.
Stone sulphur mixture: Stone sulphur mixture has phytotoxicity to Rosaceae plants such as peach, plum, plum, pear, etc. If stone sulphur mixture is used on these plants, it is best to spray it in the deciduous season, and the pesticide network suggests that it should not be in the growing season or Used during the flowering period. Stone sulphur mixture also has certain phytotoxicity to kiwi, grape, cucumber and legume flowers.
Killing pine: use the killing insects in the hot season, which has serious phytotoxicity to the pomegranate, and will cause greater damage to the flowers of the cruciferous family.
Bordeaux mixture: Bordeaux mixture is sensitive to peach and plum in the growing season. When it is lower than the multiple amount, pear, apricot and persimmon are susceptible to phytotoxicity; when it is higher than the equivalent amount, the grape is susceptible to phytotoxicity.
Insecticide: When using insecticides to control flower pests, avoid using them on hibiscus and dahlia.
Tobuzin: Dobutin should be avoided when controlling pests and diseases of kiwifruit.
Petroleum emulsion: petroleum emulsion is easy to cause phytotoxicity to certain peach tree varieties, and it is best to use it in the deciduous season.
In order to avoid pesticides causing phytotoxicity to many ornamental plants, one must use the other high-efficiency and non-toxic pesticides ; the second is to reduce the concentration as much as possible; the third is not to spray under high temperature and high humidity conditions, so the ability to avoid Loss; also pay attention to the reasonable mixed use of pesticides.
