Hexaflumuron is also known as Gaichusan. Hexaflumuron insecticide is suitable for vegetable, cotton, fruit trees, forest trees and other crops to control a variety of lepidopteran pests, and has a good effect on pests that are resistant to organic phosphorus, carbamate and pyrethroid.
Hexaflumuron can control various pests of Coleoptera, Lepidoptera, Diptera, Homoptera, etc. on cotton, vegetables and fruit trees. Special effect on cotton bollworm.
(1) Vegetable pests: To control Plutella xylostella, use 5% EC 1,000 to 2,000 times per mu to spray evenly during the egg hatching period and the 1-2 instar larvae period. For the control of Pieris rapae, spray evenly with 5% EC 2 000 to 3 000 times during the peak period of 2 to 3 instar larvae.
(2) Fruit tree pests: control fruit tree golden moths, leaf rollers, thorn moths, peach borer and other pests, use 5% emulsifiable concentrate at 1,000 to 2,000 times or 20% suspension during the egg hatching period or the young larva period The agent is 8,000 to 10,000 times liquid evenly sprayed, and the efficacy can be maintained for more than 20 days.
In addition, Hexaflumuron is used in excess of other active ingredient combination complexes, such as a pesticide composition containing pyriproxyfen and Hexaflumuron, the active ingredients are pyriproxyfen and Hexaflumuron; the mass ratio of pyriproxyfen to Hexaflumuron is 1-40:40-1 . Both pyriproxyfen and Hexaflumuron belong to insect growth regulators, but their mechanism of action is different. Pyriproxyfen is a juvenile hormone analogue and disturbs the hormone balance in insects; Hexaflumuron belongs to the class of chitin synthesis inhibitors, which can inhibit chitin synthesis Enzyme activity prevents larvae from moulting.
Pharmacological action and mechanism: Hexaflumuron is a benzoyl urea insecticide. Inhibit the synthesis of insect chitin, hinder the normal molting growth of insects, and inhibit the molting and feeding speed of pests. It has high insecticidal and egg killing activity and quick effect. Used in cotton, potato and fruit trees to control a variety of Coleoptera, Diptera and Homoptera insects.
Note: (1) This product cannot be mixed with alkaline pesticides, but it can be mixed with other insecticides for better control effect.
(2) For the prevention and control of leaf-eating pests, pesticides should be applied at the young larval stage, and borer pests should be applied during the peak period of egg laying and egg hatching. The agent has no systemic or permeability, and the spray should be uniform and thorough.
(3) It is strictly prohibited to use in and around mulberry fields, fish ponds and other places.
