The flower and fruit tree growing environment is different from ordinary crops. All pesticides cannot be used on fruit trees and flowers:
Stone sulfur 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.
Killing pine:
In the hot season, the use of chlorpyrifos to kill insects has serious phytotoxicity to pomegranates, and it has certain damage to the flowers of the cruciferous family.
Bordeaux mixture:
Peach and plum are sensitive during the growing season; when less than the amount, pears, apricots and persimmons are susceptible to phytotoxicity. When the amount is higher than that, the grapes are susceptible to phytotoxicity.
Dimethoate, Omethoate:
Kiwifruit is particularly sensitive and should not be used; it can cause obvious phytotoxicity to rose, ornamental, apricot and pear, such as plum blossom, cherry blossom, eucalyptus, and sea bream. Dimethoate is also harmful to coral flowers, if it is 6~ Spraying omethoate in October 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. Usually, 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.
