Abstract
The invention relates to a pesticide combination, which is characterized by comprising the active ingredients including pyridalyl (A) and an organophosphorus insecticide (B) which can be chlorpyrifos, phoxim, profenofos, triazophos, diazinon, pyridaphenthione, malathion or acephate. The pesticide combination of the invention has good control effects on the common pests on such field crops as paddy rice, wheat, corns, cotton, hemp, soybean and the like, and especially has better control effect on lepidopterous pests.
Description
Technical field
The present invention relates to a kind of composition pesticide and application thereof, especially a kind of composition pesticide that contains pyridalyl.
Background technology
Organophosphorus insecticides is owing to its wider insecticidal spectrum, diversified desinsection mode, the cheap characteristics such as cost are widely used on the field crop it.But also there are a lot of problems in organophosphorus insecticides, and for example: the toxicity of a lot of organophosphorus insecticideses is higher; Most organophosphorus insecticide dosages are large; Long-term use the pest resistance that causes rise (He Yanping, Ma Enbo. insect is to the organic phosphorous insecticide resistance, " chemistry of life ", 2003,23 (5)).Medium or the low toxicity of toxicity of chlopyrifos (chlorpyrifos), phoxim (phoxim), Profenofos (profenofos), Hostathion (Triazophos), diazinon (diazinon), pyridaphethione (pyridaphenthione), malathion (malathion), orthene (acephate) is the malicious organic phosphorous insecticide substitute species of height.Composite between the machine that mainly includes Phosphorus and organic phosphates, Avermectins and organic phosphates, chrysanthemum ester class and the organic phosphates at present, arranged much about the built agent of organophosphorus insecticides.Insect is fast to the resistance rate of climb of Avermectins and chrysanthemum ester class, and the not high and inadequate science of the built agent drug effect between the organic phosphates, so these composite kinds that contain organic phosphor still can not satisfy the needs of agricultural production well at present.
Pyridalyl: english common name pyridalyl, chemical name: 2,6-two chloro-4-(3,3-, two chloroallyloxyaminos) phenyl 3-[5-(trifluoromethyl-2 hydroxy pyrimidine) propyl group] ether, it has the brand-new mechanism of action, does not have cross resistance with conventional dose.Pyridalyl has simultaneously tags and stomach poison function, and the larva of lepidoptera pest is had very high activity.There is speed of action fast, to the various useful low characteristics of arthropodan toxicity.But as a kind of new component, the price of pyridalyl is higher, and this has limited its use on field crop to a great extent.
Summary of the invention
The object of the present invention is to provide a kind of synergetic pesticide composition of preventing and treating paddy rice, wheat, corn, cotton, fiber crops, Soybean and Other Crops insect.
For solving the problems of the technologies described above, the inventor finds that by a large amount of biologicall test screenings pyridalyl and organophosphorus insecticides are composite with certain proportion, and the lepidoptera pest common to crop has synergistic effect.
