A kind of Pesticidal combination containing niclosamide and anabasine pesticide
Technical field
The invention belongs to pesticides application technical field, is related to a kind of composition pesticide, and specifically one kind contains niclosamide
With the Pesticidal combination of anabasine pesticide.
Background technology
Niclosamide ethanolamine salt (abbreviation niclosamide), also makes spiral shell kill, hundred spiral shells kill, niclosamide, is amides compound, is
A kind of strong invertebrate poison, has stomach poison function, has strong killing action to spiral shell ovum, blood fluke cercaria etc..Effect is rapid, medicine
Effect is lasting.Product has 50% and 70% wettable powder, 25% missible oil, and there is production in Sichuan Prov. Chemical Industry Research & Design Academy.Can
Rice Pomacea canaliculata is prevented and treated, kills oncomelania, agriculturally can also be used for preventing and treating slug.
Nitenpyram (nitenpyram), nicotimine class, it is another Japanese developed after imidacloprid, pyridine worm miaow
Novel product.Absorbability, osmosis, insecticidal spectrum with brilliance are wide, safety is without poisoning.It is to prevent and treat sucking pest such as
Trialeurodes vaporariorum, aphid, pear sucker, leafhopper, the regeneration product of thrips.
Clothianidin is a kind of insecticide in anabasine, is a kind of highly effective and safe, the novel pesticide of high selectivity, its
Effect is similar with nAChR, with tag, stomach toxicity and systemic activity.Be mainly used in rice, vegetables, fruit tree and its
Prevent eliminating aphis on his crop, leafhopper, thrips, the Semiptera such as plant hopper, coleoptera, the desinsection of Diptera and some Lepidoptera class pests
Agent, have efficiently, wide spectrum, dosage is few, toxicity is low, the drug effect lasting period is long, to crop without poisoning, safe to use and conventional pesticide
The advantages that no interactions resistance, there are interior suction and the osmosis of brilliance, be the another kind for substituting high-toxic organic phosphorus agricultural chemicals.Its structure
Novel, special, performance is more excellent compared with traditional nicotinic insecticide, it is possible to which become international large-scale insecticide product
Kind.
Diacloden is a kind of second generation nicotinoids high-efficient low toxicity insecticide of brand new, has stomach toxicity to insect, tags
And systemic activity, for foliar spray and soil root irrigation.Rapidly by interior suction after its dispenser, and each position of plant is transmitted to,
There is good preventive effect to sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc..
MTI-446 (dinotefuran) is the nicotinic insecticide of Mitsui company research and development.Itself and existing nicotinoids
The chemical constitution of insecticide is far from each other, and its tetrahydrofuran base instead of former chloro-pyridine base, chloro-thiazole base,
Without halogen.Meanwhile it is also different with nicotine in aspect of performance, so, people are referred to as " furans cigarette at present
Alkali ".The medicament have tag, stomach toxicity and root absorbability are strong, quick-acting height, the lasting period long 3-4 weeks (theoretical lasting effect 43 days),
The features such as insecticidal spectrum is wide, and have excellent preventive effect to sucking insect, and be to show that very high desinsection is lived in very low dosage
Property.It is mainly used in preventing and treating aphid, leafhopper, plant hopper, Ji in the various crops such as wheat, rice, cotton, vegetables, fruit tree, tobacco leaf
Horse, aleyrodid and its resistant strain, while have height to coleoptera, Diptera and Lepidoptera, Diptera, beetle mesh and total wing mesh insect
Effect, and have efficiently to sanitary insect pests such as blattaria, termite, houseflies.
It is current development pesticide new product and preventing and treating resistance disease that the pesticide active ingredient of the different mechanisms of action is carried out into compounding
A kind of effective quick way of insect pest.After different pesticide active ingredients are compounded, three kinds of type of action can be shown:It is added
Effect, synergistic effect and antagonism.Generally, only by after largely testing and just learning different pesticide active ingredients compounding
Type of action.The Recompounded pesticide of screening tool synergistic effect, can significantly improve prevention effect, reduce Pesticide use amount, reduce
Cost accounting, preventing and treating spectrum can also be expanded, delay the generation of pest and disease damage resistance, be the important means of current integrated pest prevention and control
One of.
Inventor is tested by a large amount of indoor biometricses and field control effectiveness test, filters out niclosamide and anabasine pesticide
Pesticidal combination, said composition have synergistic effect within the specific limits.
So far, the Pesticidal combination using niclosamide and anabasine pesticide as active ingredient, at home and abroad there is not yet
Relevant report.
