Abstract
The invention discloses a pesticide composition containing chlorpyrifos. The pesticide composition consists of the following components in parts by weight: 40-120 parts of chlorpyrifos, 5-15 parts of pymetrozine and 15-30 parts of buprofezin. The invention also provides application of the pesticide composition containing chlorpyrifos in the prevention and treatment of brown planthoppers. The method has the advantages that the harm can be controlled by using the pesticide composition one time, and quick and persistent effects are excellent, so that the toil and cost caused by a poor control effect after the use of drugs multiple times are avoided, the adverse effects on the environment of pesticide residue in rice is reduced, and the labor intensity of the use of a large amount of water is alleviated. The maximum control effect of the pesticide composition on the brown planthoppers reaches 98.8%.
Description
Technical field
The invention belongs to the Chemical Control of Harmful Insects field, particularly a kind of composition pesticide of containing chlopyrifos and application thereof.
Background technology
Brown planthopper is one of most important insect of hazard rice, along with being widely used of Buprofezin recent two decades, has produced heavier pesticide resistance, and alone imitation is poor, control plant hopper pymetrozine, chlopyrifos or pymetrozine, Buprofezin, the built agent of chlopyrifos etc.With the increase of access times, its preventive effect descended gradually in recent years.Particularly, after the heading, the Rice Population amount of growth reaches peak, grows densely, and brown planthopper generation overlap phenomenon is serious, and plant hopper expands to top by concentrating on bottom early stage.Since two thousand five Later Stage of Rice prevents that brown planthopper is difficult to reach desirable preventive effect, high worm amount field particularly, and the peasant is in frequent medication of short time, even five days with four times, brown planthopper can not be controlled to below index for control to adult, the nymph control of medication, after several days, has again large quantities of ovum hatching imago/nymphs.Because engineering department recommend prescription mostly be pymetrozine or chlopyrifos, the single dose of pymetrozine or binary mixture, be difficult to once gather effect.What is more, part peasant for control brown planthopper cause harm will on the crops such as cotton, use height poison, highly toxic pesticide (as 1605, thimet, 5a,6,9,9a-hexahydro-6,9-methano-2,4) for the plant hopper control, agricultural product and ecotope are formed to harmful effect.
Summary of the invention
Goal of the invention: first purpose of the present invention is to provide a kind of composition pesticide of containing chlopyrifos.Second purpose of the present invention is to provide the application of this composition pesticide.
Technical scheme: the invention provides a kind of composition pesticide of containing chlopyrifos, formed by following component by ratio of weight and the number of copies: 40～120 parts of chlopyrifos, 5～15 parts of pymetrozines, 15～30 parts of Buprofezins.
Preferably, by following component, formed by weight: 80～120 parts of chlopyrifos, 10～15 parts of pymetrozines, 20～30 parts of Buprofezins.
Preferably, by following component, formed by weight: 80 parts of chlopyrifos, 10 parts of pymetrozines, 20 parts of Buprofezins.
The application of the composition pesticide of described containing chlopyrifos aspect the control brown planthopper.
The hundred cave worm amounts of brown planthopper are 5000 when following, adopt the low dosage of the composition pesticide of containing chlopyrifos, when the hundred cave worm amounts of brown planthopper are 5000～15000, adopt the middle dosage of the composition pesticide of containing chlopyrifos, the hundred cave worm amounts of brown planthopper are 15000 when above, adopt the composition pesticide high dose of containing chlopyrifos, described low dosage is every mu and uses chlopyrifos 40g, pymetrozine 5g, Buprofezin 15g, described middle dosage is every mu and uses chlopyrifos 80g, pymetrozine 10g, Buprofezin 22.5g, described high dose is every mu and uses chlopyrifos 120g, pymetrozine 15g, Buprofezin 30g.
Beneficial effect: the Heterosis of the method can be controlled harm at a drug, quick-acting all excellent with holding effect, avoids in the past the still not good painstaking and cost of preventive effect of repeatedly medication, has reduced the residual harmful effect to environment of agricultural chemicals in rice.Alleviate the labour intensity of a large amount of waters.This composition pesticide has been up to 98.8% to the preventive effect of brown planthopper.
