Problems solved by technology

Since 2005, it is difficult to achieve the ideal control effect against brown planthoppers in the later stages of rice, especially in fields with high insect populations. Farmers frequently use pesticides in a short period of time, even four times in five days, but they cannot control brown planthoppers below the control index, adults and nymphs. After a few days of control, another large number of eggs hatched into nymphs
Because most of the prescriptions recommended by the technical department are pymetrozine or chlorpyrifos, the single dose or binary mixture of pymetrozine is difficult to get the effect at one time
What's more, in order to control brown planthopper damage, some farmers use highly toxic and highly toxic pesticides (such as 1605, phorate, endosulfan) used on cotton and other crops for planthopper control, causing adverse effects on agricultural products and the ecological environment

Embodiment 1

[0012] A pesticide composition containing chlorpyrifos is composed of the following components in percentage by weight: 40 parts of chlorpyrifos, 5 parts of pymetrozine, and 15 parts of buprofezin.

[0013] The application of the pesticide composition containing chlorpyrifos in controlling brown planthopper. When the number of burrows of brown planthoppers is less than 5000, use a low dose of the pesticide composition containing chlorpyrifos; When the number of cave worms is more than 15,000, a high dose of a pesticide composition containing chlorpyrifos is used. The low dose is 40 g of chlorpyrifos, 5 g of pymetrozine, and 15 g of buprofezin per mu, and the medium dose is 80 g of chlorpyrifos per mu. .

Embodiment 2

[0015] A pesticide composition containing chlorpyrifos is composed of the following components in percentage by weight: 120 parts of chlorpyrifos, 15 parts of pymetrozine, and 30 parts of buprofezin.

[0016] The application of the pesticide composition containing chlorpyrifos in controlling brown planthopper. When the number of burrows of brown planthoppers is less than 5000, use a low dose of the pesticide composition containing chlorpyrifos; When the number of cave worms is more than 15,000, a high dose of a pesticide composition containing chlorpyrifos is used. The low dose is 40 g of chlorpyrifos, 5 g of pymetrozine, and 15 g of buprofezin per mu, and the medium dose is 80 g of chlorpyrifos per mu. .

Embodiment 3

[0018] A pesticide composition containing chlorpyrifos consists of the following components by weight percentage: 80 parts of chlorpyrifos, 10 parts of pymetrozine, and 20 parts of buprofezin.

[0019] The application of the pesticide composition containing chlorpyrifos in controlling brown planthopper. When the number of burrows of brown planthoppers is less than 5000, use a low dose of the pesticide composition containing chlorpyrifos; When the number of cave worms is more than 15,000, a high dose of a pesticide composition containing chlorpyrifos is used. The low dose is 40 g of chlorpyrifos, 5 g of pymetrozine, and 15 g of buprofezin per mu, and the medium dose is 80 g of chlorpyrifos per mu. .

[0020] In mid-September 2011, a field test was carried out in a field with a large number of brown planthoppers and a small amount of puncture. 30 kilograms of water per mu, spray fine mist when there is dew in the morning and evening, the field will have a water layer during th...

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 [0001] The invention belongs to the field of pest chemical control, in particular to a pesticide composition containing chlorpyrifos and its application. Background technique [0002] Brown planthopper is one of the most important pests that harm rice. With the extensive use of buprofezin in the past two decades, it has developed serious drug resistance. Compounds of philodrone, buprofezin, chlorpyrifos, etc. In recent years, with the increase of the frequency of use, its control effect has gradually declined. Especially after heading, the growth of the rice population reached its peak, and the growth was dense. The generation overlap of brown planthoppers was serious, and the planthoppers concentrated in the lower part of the early stage and expanded to the upper part. Since 2005, it is difficult to achieve the ideal control effect against brown planthoppers in the later stages of rice, especially in fields with high insect populations. Farmers frequently ...
