Agriculture pesticide insecticide Hexaflumuron Use of as a termiticide
What is hexaflumuron?Hexaflumuron is a termiticide an insecticide specifically used on termites.Hexaflumuron is a chitin synthesis inhibitor used to bait and eliminate termite colonies.Cas86479-06-3 Hexaflumuron spreads efficiently through entire populations through mutual exchange of liquids via regurgitation.Termites are unable to metabolize hexaflumuron and clearance is slow, resulting in up to 100% elimination. Hexaflumuron has also been tested for use with the raisin moth, cowpea weevil, and Asiatic rice borer with positive results.
This chemical is used as part of a termite inspection, monitoring and baiting system.It is the first active ingredient registered with the EPA as a reduced-risk pesticide. A reduced-risk pesticide is one the EPA believes poses less risk to human health and the environment than existing alternatives.
How does hexaflumuron work?
Hexaflumuron is an insect growth regulator that works by stopping the insect’s growth. It interferes with chitin synthesis, whichtermites need to form a new exoskeleton.
Hexaflumuron is part of a pest monitoring system and is used selectively in baiting stations where termite activity is present. Termites are social insects that share food and feeding sites. Foraging termites recruit nest mates to feeding sites by leaving a chemical trail to the site. After a few termites feed on the hexaflumuron bait, it is expected that the other members of the colony will also feed on the bait.
Pest control operators use hexaflumuron as part of an aboveground and underground baiting system. They place it in tamper-resistant bait stations where foraging termites consume it.
What is the application Hexaflumuron
Hexaflumuron is an odorless white solid that is formulated into low-concentration solid briquettes that are contained within tamper-resistant bait stations. It act by disrupting chitin synthesis in developing termites.
Chitin is the main component of the termite exoskeleton. Hexaflumuron and its end-use termite bait products are registered by the EPA for use to protect structures against subterranean termite colonies.
Hexaflumuron It is used in both above-ground and in-ground bait stations as part of a termite monitoring and control program. Target sites can include buildings, fences, utility poles, decking, landscape plantings, trees, and other wood structures that can be damaged by termite foraging and feeding.

What is the use of Insecticide Hexaflumuron
Hexaflumuron is used to control subterranean termite colonies. It is used in above-ground and inground bait stations as part of termite monitoring and control programs. Target sites include buildings, fences, utility poles, decking, landscape plantings, trees, and other wood structures that can be damaged by termite foraging and feeding. Hexaflumuron products are used only by licensed pest management professionals.
Used in agriculture for control of larvae of Lepidoptera, Coleoptera, Homoptera, and Diptera on top fruit, cotton, and potatoes. Major use now is in bait, for control of subterranean termites.
1,each mu with 20% suspension Agent 15-20 grams, with water spray. It can also be mixed with pyrethroid pesticides to expand the control effect.
2, the control of Spodoptera litura, in the spawning peak or incubation period, with 20% suspension of 400-500ppm liquid spray, can kill the larvae, and have the effect of killing eggs.
3, control of beet armyworm, in the early stage of the larvae with 20% suspension: 100ppm spray. Spray should be uniform and thoughtful, otherwise the control effect is poor.
How to apply Insecticide Hexaflumuron
Hexaflumuron is benzoylurea insect growth regulators, the mechanism of action is to inhibit the formation of chitin, hinder the normal molting and metamorphosis of pests, but also inhibit the feeding speed of pests. It has the characteristics of high insecticidal activity, broad insecticidal spectrum, strong knock-down ability and quick-acting. Can control cotton, fruit trees on the Coleoptera, Diptera, Lepidoptera, Homoptera pests, both egg killing activity. In particular, the effect of cotton bollworm and other pests is very good, and the mite is ineffective. For the prevention and control of cotton bollworm, pink bollworm in the egg incubation period, young insects into the bud, Boll, with 5% emulsifiable concentrate 1500~2000 times liquid spray.can effectively control a variety of pests on cotton, vegetables, fruit trees, trees and other crops.
Hexaflumuron is belongs to benzoylurea insecticides, killing insect pests by inhibiting chitin synthesis in insects flufluron is a specific insecticide with high insecticidal activity and broad insecticidal spectrum, which can be used in vegetables, cotton, fruit trees, trees and other crops control a variety of lepidopteran pests, and organic phosphorus, carbamate, pyrethroid resistant pests have a good effect, but the silkworm, fish and other toxic.

Features of hexaflumuron
Hexaflumuron is a specific insecticide with high insecticidal activity and wide insecticidal spectrum. It can be used to control various Lepidoptera pests in vegetables, cotton, fruit trees, forest trees and other crops. It has good effects on pests resistant to organophosphorus, carbamates and pyrethroids, but it is highly toxic to silkworms and fish. It has the characteristics of high insecticidal activity, wide insecticidal spectrum, strong knockdown power and quick effect.
Hexaflumuron is Mainly stomach poisoning and contact killing. After the pest is exposed to the pesticide, it cannot form a new epidermis when moulting, and the insect body is deformed and dies.The rate of killing pests is relatively slow.

production method Hexaflumuron
Hexaflumuron preparation method -3, 5-dichloro-4-(1,1,2, reaction of 2-tetrafluoroethoxy) aniline with phosgene (or oxalyl chloride) to convert the amino group to isocyanato group to give 3, 5-dichloro-4-(1,1,2, 2-tetrafluoroethoxy) phenyl isocyanate, and then with 2,6-difluorobenzamide (preparation method see fluoropyridine urea) role, synthesis of fluorine ring urea. See references [3]. Preparation Method di -2, 6-difluorobenzoyl isocyanate (see fluorizil and fluvoxuron for preparation method) and 3, 5-dichloro-4-(1,1,1, 2-methylfluoroethoxy) aniline was refluxed and reacted in a toluene solvent for 1H to obtain a flourescent urea.
