Description

Composition pesticide based on ivermectin
Technical field
The present invention relates to a kind of synergetic pesticide composition, particularly relate to a kind of synergetic pesticide composition that comprises ivermectin and be selected from arbitrary active insecticidal components of indenes worm prestige, thiophene worm piperazine and pyrrole aphid ketone.
Background technology
Ivermectin (Ivermectin) is to be lead compound with the Avermectin, by two key hydrogenations, and structure optimization and the novel synthetic pesticide succeeded in developing.Structure optimization product as agricultural antibiotic, compare with the parent Avermectin, its expelling parasite and acaricidal activity have not only been kept, and safety is higher, be difficult for to produce resistance, for the production of vegetables, fruit, cotton etc. provide efficient a, high security and with the good biogenic pesticide insecticide of Environmental compatibility.Ivermectin has stomach toxicity and action of contace poison to mite class and insect, and the horizontal infiltration conduction is arranged.Also can be used as additive and get antiparasitic agent.Nematode, insect and mite are all killed effect, be used for the treatment of intestines and stomach nematodosis, acariasis and the parasitic insect disease of fowl poultry.
Indenes worm prestige (indoxacarb), belong to Yi Zhong oxadiazine insecticides, it is insect sodium-ion channel inhibitor, it is mainly to tag and stomach poison function, there is not cross resistance in other insecticides, and to natural enemy insect safety, can be used for the insect comprehensive regulation (IPM) and resistance management (RPM), be used to that crops such as vegetables, cotton, beet prevent and treat various insects such as beet armyworm, tomato moth, diamond-back moth, imported cabbageworm, cotton bollworm, pink bollworm, cotten aphid, rice stinkbug, fruit eats into moth, potato leaf is first-class, and each instar larvae is all had good control efficiency.
Thiophene worm piperazine (thiamethoxam) is the anabasine insecticide of a kind of efficient, low toxicity, wide spectrum, its mechanism of action mainly is that selectivity suppresses insect central nervous system nicotinic acid acetylcholinesterase acceptor, and then the normal conduction of blocking-up insect central nervous system, death when causing insect the paralysis machine to occur.Thiophene worm piperazine not only have tag, stomach toxicity and systemic activity, and have better safety, wider insecticidal spectrum and characteristics such as speed of action is fast, the lasting period is long, be to replace those better kinds to mammalian toxicity height, the organic phosphates that residual and environmental problem are arranged, carbamates and organochlorine insecticides.Thiophene worm piperazine is to coleoptera, diptera, Lepidoptera, especially homoptera pest has high activity, can effectively prevent and treat insect such as various aphids, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato beetle, nematode, ground beetle, leaf miner and polytype produce resistance to chemical pesticide insect.Thiophene worm piperazine both can be used for cauline leaf, seed treatment, also can be used for soil treatment.
Pyrrole aphid ketone (pymetrozine), chemical name: (E)-4,5-dihydro-6-methyl-4-(3-pyridine methylene amino)-1,2,4-triazine-3 (2H)-ketone, be a kind of insecticidal/acaricidal agent that is specifically designed to control sucking pest such as aphid, trialeurodes vaporariorum, rice leafhopper, small brown rice planthopper etc., be widely used in crops, vegetables, ornamental plants, cotton, hop, fruit tree, citrus and paddy rice etc. both at home and abroad.This insecticidal/acaricidal agent has selectivity highly to insect, to people, mammal low toxicity, to birds, fish, non-target arthropods safety.Pyrrole aphid ketone has unique mode of action to insect, and it is different with conventional insecticidal/acaricidal agent, and to be the insect that stops sucking mouth parts on physiology insert plant tissue with lancet makes it hungry and death is good to rice fulgorid quick-acting.
The inventor studies have shown that by a series of ivermectin is mixed with the arbitrary active insecticidal components that is selected from indenes worm prestige, thiophene worm piperazine and pyrrole aphid ketone target pest is had extremely strong synergistic effect, thereby has finished the present invention.

Biological Examples 1: ivermectin and indenes worm prestige are mixed to the toxicity test of cabbage caterpillar
With resistance cabbage caterpillar (Pieris rapae) 3 instar larvaes is tested object.This confession examination cabbage caterpillar is picked up from Fujian China Foochow vegetable field, and it has reached high anti-level to the resistance of pyrethroid and organophosphorus insecticides.
The leaf dipping method that adopts international resistance Action Committee (IRAC) to carry.The Mixed Pharmacy of reagent agent and different proportion thereof is diluted to 5 series concentration with running water, cabbage leaves is cut into the fritter of 6~7cm, immerse the about 5S of soup and take out, after indoor drying, again blade is put into and be connected to the culture dish that tries worm, preserve moisture with wet cotton balls.Compare with clear water, each is handled 3 times and repeats, and each repeats 1 culture dish, and each culture dish is put and tried worm 20 three ages.24h, 48h, each handling dead of 72h observed and recorded, the borer population of living behind the medicine.Larva death standard: touch examination worm polypide with the writing brush point, do not have obvious autonomic response person and be judged as death.Calculate the corrected mortality that each is handled with the Abbott formula, with the lethal concentration of 50 (LC of 72h after the computing of DPS software 50), correlation coefficient and regression equation.According to the insecticide synergy virulence computational methods of reports such as Sun Yunpei, calculate co-toxicity coefficient (CTC).The symphyogenetic evaluation method of mixture is to adopt the abundant method of Sun Yun, promptly calculates the co-toxicity coefficient (CTC) of each proportioning combination, estimates the interaction property of mixture by comparing co-toxicity coefficient.The result is as shown in table 1:
