Background technology
Niclosamide ethanolamine salt (abbreviation niclosamide), also makes spiral shell kill, hundred spiral shells kills, niclosamide, are amides compound, be a kind of strong invertebrate poison, have stomach poison function, have strong killing action to spiral shell ovum, blood fluke cercaria etc.Effect is rapid, lasting medicine.Product has 50% and 70% wetting powder, and 25% missible oil, there is production in Sichuan Prov. Chemical Industry Research & Design Academy.Paddy rice Pomacea canaliculata can be prevented and treated, Killing Oncomelania Hupensis, agriculturally also can be used for preventing and treating slug.
Nitenpyram (nitenpyram), nicotimine class is another novel product that Japan develops after Imidacloprid, pyridine worm miaow.Have that remarkable interior absorption, osmosis, insecticidal spectrum are wide, safety is without poisoning.That control sucking pest is as the regeneration product of trialeurodes vaporariorum, aphid, pear sucker, leafhopper, thrips.
Clothianidin is a kind of insecticide in anabasine, is the novel pesticide of a class highly effective and safe, high selectivity, and its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.To be mainly used on paddy rice, vegetables, fruit tree and other crops anti-ly eliminating aphis, leafhopper, thrips, the Semiptera such as plant hopper, coleoptera, diptera and some Lepidoptera class pest insecticide, have efficient, wide spectrum, consumption are few, toxicity is low, the drug effect lasting period long, to crop without poisoning, use safety and conventional pesticide without advantages such as cross resistances, having remarkable interior suction and osmosis, is the another kind of alternative high-toxic organic phosphorus agricultural chemicals.Its novel structure, special, performance is more excellent compared with traditional nicotinic insecticide, and likely become international large-scale insecticide variety.
Diacloden is a kind of second generation nicotinoids high-efficient low toxicity insecticide of brand new, has stomach toxicity, tags and systemic activity to insect, for foliar spray and soil root irrigation.Rapidly by interior suction after its dispenser, and be transmitted to each position of plant, to sucking pest as aphid, plant hopper, leafhopper, aleyrodid etc. have good preventive effect.
The nicotinic insecticide that MTI-446 (dinotefuran) is researched and developed for Mitsui company.The chemical constitution of itself and existing nicotinic insecticide is far from each other, and its tetrahydrofuran base instead of former chloro-pyridine base, chloro-thiazole base, not containing halogen.Meanwhile, also different with nicotine at aspect of performance, so current people are referred to as " furans nicotine ".This medicament has the features such as tag, strong, the quick-acting height of absorption in stomach toxicity and root, long 3-4 week lasting period (theoretical lasting effect 43 days), insecticidal spectrum are wide, and have excellent preventive effect to sucking insect, and namely show very high insecticidal activity at very low dosage.Be mainly used in the aphid in the various crop such as control wheat, paddy rice, cotton, vegetables, fruit tree, tobacco leaf, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof, have efficiently coleoptera, diptera and Lepidoptera, diptera, beetle order and total wing order insect simultaneously, and have efficiently sanitary insect pests such as blattaria, termite, houseflies.
Being carried out by the pesticide active ingredient of the different mechanism of action composite is the one mode effectively efficiently developed pesticide new product at present and prevent and treat resistance damage by disease and insect.Different pesticide active ingredient carry out composite after, three kinds of type of action can be shown: summation action, synergistic effect and antagonism.Usually, only have by a large amount of tests just can learn different pesticide active ingredient composite after type of action.The Recompounded pesticide of screening tool synergistic effect, can significantly improve control efficiency, reduce Pesticide use amount, reduce cost accounting, and can also expanding prevention compose, delaying the generation of damage by disease and insect resistance, is one of important means of current integrated pest prevention and control.
Inventor is tested and field control effectiveness test by a large amount of indoor biometrics, and filter out the Pesticidal combination of niclosamide and anabasine pesticide, said composition has synergistic effect within the specific limits.
Up to now, the Pesticidal combination being active ingredient with niclosamide and anabasine pesticide, there is not yet relevant report at home and abroad.
Summary of the invention
