Among the pests and diseases of flower and fruit plants, chemical control is one of the important means. Because chemical pesticides have a wide range of uses, high control efficiency and simple method. However, some flower and fruit plants are sensitive to certain pesticides, so be careful when using them to avoid phytotoxicity. Its specific is:
1. Dimethoate: It is easy to produce phytotoxicity to plum, peach, cherry, apricot, fig, olive, hop, and compositae, and should be used with caution.
2, Omethoate: hops, Compositae, apricot, peach, plum, olive, fig, citrus sensitive to Omethoate 500 below the drug solution, with caution.
3, trichlorfon: sensitive to cherry blossoms, apples, abnormal phytotoxicity, should be used with caution.
4. Dichlorvos: It is easy to cause phytotoxicity to flowers such as plum, peach, cherry, rhododendron, eucalyptus, and rose. unavailable.
5, killing pine: under high temperature conditions, cruciferous plants such as violet, sweet snowballs, kale and other susceptibility to phytotoxicity, with caution.
6, insecticidal cockroaches: easy to produce medicinal damage to dahlia, hibiscus and other flowers, can not be used.
7. Malathion: Under high temperature conditions, cherries, pears and melons are susceptible to phytotoxicity and should be used with caution.
8, quasi-sulfur: for the cruciferous seedlings and pears, peaches, cherries, hops and other susceptibility to phytotoxicity, with caution.
9, dicofol: some varieties of apples and citrus are susceptible to phytotoxicity, disabled.
10. Bordeaux mixture: Grapes are sensitive to lime. It is advisable to use Bordeaux mixture with less lime content. Peach, plum, pear, persimmon, etc. are sensitive to copper, and it is generally not suitable to use Bordeaux mixture.
11, stone sulfur mixture: sensitive to plum, plum, pear, grape and legumes, easy to produce phytotoxicity, should be used with caution.
12. Daisen Ammonium: Legumes are sensitive to the concentration of 1000% solution of dexamethasone, especially when the temperature is high, so it should be used with caution.
13. Pentachloronitrobenzene: The shoots of plants are sensitive to large doses of pentachloronitrobenzene solution, which is highly susceptible to phytotoxicity. Plants should not be used during the shoot period.
