Description

Pesticides composition for killing nematodes
Technical field
The composition pesticide that the present invention relates to, is with effective constituents A (clothianidin or Diacloden) and effective ingredient B (tioxazafen) being active component, compositions is to pathogenic nematode Meloidogyne incognita and soybean cyst nematode Heterodera glycines and the work caused thereof Thing nematicide has synergistic function, it is adaptable to prevent and treat by the crop nematicide of pathogen nematicide, especially Root Knot line Root of the crop Root-knot that worm causes and the crop Cyst nematode that soy bean cyst roundworm causes.
Background technology
Clothianidin (clothianidin), clothianidin is a kind of insecticide in anabasine, is a class highly effective and safe, height Selective novel pesticide, its effect is similar with nAChR, have tag, stomach toxicity and systemic activity.Mainly Anti-on Oryza sativa L., vegetable, fruit tree and other crops eliminate aphis, leafhopper, thrips, the Semiptera such as plant hopper, coleoptera, Diptera and The insecticide of some Lepidoptera class pest, have efficiently, wide spectrum, consumption are few, toxicity is low, drug effect lasting period length, to crop without medicine The advantages such as evil, use safety and conventional pesticide no interactions resistance, have interior suction and the osmosis of brilliance.
Diacloden (thiamethoxam) is the second filial generation nicotinoids high-efficient low toxicity insecticide of a kind of brand new, to insect There is stomach toxicity, tag and systemic activity, for foliar spray and soil root irrigation.Rapidly by interior suction after its dispenser, and conduct To each position of plant, sucking pest such as aphid, plant hopper, leafhopper, aleyrodid etc. there is good preventive effect.
Tioxazafen, chemical name: 3-phenyl-5-(thiophene-2-base)-1,2,4-diazole；Non-stifling property nematicide Agent, because it is more environmentally friendly, it is safer to use, less on the impact of people, is described as the ideal substitute of clothianidin, greenhouse and land for growing field crops examination Testing and show, the performance of this novel nematicide is equivalent to or better than the reference product of current commercialization.It is reported, tioxazafen To the soybean cyst nematode Heterodera glycines on Semen sojae atricolor, root-knot nematode, kidney shape nematicide, the pratylenchus on Semen Maydis, root-knot nematode, minute hand nematicide, Kidney shape nematicide on Cotton Gossypii, root-knot nematode etc. are respectively provided with fabulous biological activity.
Plant nematode is the pathogenic microorganism that a class is very harmful, and it has a very wide distribution, of a great variety, environment adaptation Ability is strong, can colonize in the root system of plant, stem, leaf, seed, plumelet and fruit, can be by feeding activity to host plant Cause mechanical damage, and rob the nutrition of host plant, especially its esophageal gland secretions can cause host plant occur one be Epidemy becomes, and also can jointly infect host plant with other pathogenic microorganism, cause compound disease, cause production loss.In the whole world In the range of, the agricultural losses that plant nematode is caused every year are up to more than 100,000,000,000 dollars, seriously constrain agricultural economy Development.
Being found by experiment that, the one in clothianidin or clothianidin and tioxazafen are used in mixed way black to Root Knot line The plant pathogeny line insect such as worm and soybean cyst nematode Heterodera glycines has synergistic function especially at the part by weight model of 20:1～1:20 Enclosing and interior have obvious potentiation to Meloidogyne incognita and soybean cyst nematode Heterodera glycines, preferred weight ratio is 6:1～1:10, more Weight ratio of greater inequality example is 3:1～1:6.
By certain technological means clothianidin, Diacloden can be with excipient for agriculturally commonly using with tioxazafen compositions Dosage form such as granule, aqueous emulsion, micro-capsule suspension, the popularization and application of the present invention that is more convenient for after excipient.
Summary of the invention
The invention belongs to technical field of compounded pesticide, it is provided that a kind of nematicide synergetic pesticide composition, for crop nematicide Sick prevention and control especially provide one effectively to manage instrument for root of the crop Root-knot and Cyst nematode.
The present invention is achieved through the following technical solutions: a kind of pesticides composition for killing nematodes, including effective constituents A and B and Usual auxiliaries, wherein effective constituents A one in clothianidin or Diacloden, effective ingredient B is tioxazafen, effectively becomes The ratio of weight and number dividing A and B is 20:1～1:20；Preferred weight ratio is 6:1～1:10, and more excellent part by weight is 3:1～1: 6。
Described composition pesticide effective ingredient total content is 0.1%～60%.
Described composition pesticide adds auxiliary agent and excipient and makes granule, aqueous emulsion, micro-by certain technological means The dosage form that capsule suspension etc. are agriculturally conventional.
