Embodiment 1

[0007] Example 1. During the heading and grain filling period in the southern rice area, the temperature is high and dry, rice planthoppers and rice floating dust occur frequently, rice vertical insects are seriously harmed, and the two and three stem borers are prevalent. The following proportions are used:

[0008] Weigh 200 grams of 40% dimethoate emulsion, 200 grams of trichlorfon, 150 grams of dichlorvos, 100 grams of methamidophos, and 100 grams of pyrethrin. Put it into 300 catties of clean water, stir well, and spray the crops in a diamond shape with a sprayer. The spraying area is 10-30 acres, and the time is about 30 minutes. The on-site pest mortality rate is 30-50%, and the pest mortality rate is 95% within 24 hours. the above.

Embodiment 2

[0009] In Example 2, 600 grams of 40% dimethoate emulsion, 600 grams of trichlorfon, 400 grams of dichlorvos, 300 grams of methamidophos, and 300 grams of pyrethrum were weighed. Put it into 900 catties of clean water, stir well, and spray the crops in a diamond shape with a sprayer. The spraying area is 10-30 acres and the time is about 30 minutes. The on-site pest mortality rate is 30-50%, and the pest mortality rate is 95% within 24 hours. the above.

Embodiment 3

[0010] In Example 3, 250 grams of 40% dimethoate emulsion, 250 grams of trichlorfon, 200 grams of dichlorvos, 100 grams of methamidophos, and 80 grams of pyrethrum were weighed. Put it into 400 catties of clean water, stir well, and spray the crops in a diamond shape with a sprayer. The spraying area is 10-30 acres. The time is about 30 minutes. The pest mortality rate is 30-50% and the pest mortality rate is 95% within 24 hours. the above.

Abstract

The invention discloses a combined pesticide with a broad-spectrum insecticidal action. The combined pesticide is prepared from the following pesticides in parts by weight: 10-30 parts of 40 percent dimethoate emulsion, 10-30 parts of dipterex, 10-20 parts of dichlorvos, 8-12 parts of methamidophos and 8-12 parts of polyester pesticide. The combined pesticides are mixed, weighed, diluted with 300-500 parts of water, and sprayed. The pesticides with different mixture ratios are sprayed according to different plant diseases and insect pests. The combined pesticide is prepared from commercially-available pesticides, and different pesticide mixture ratios are adopted according to different plant diseases and insect pests. The combined pesticide has the advantages of high diluting concentration, small dosage, broad insecticidal spectrum, strong action, low toxicity and harmlessness to human beings and livestock, and has insecticidal actions on plant pests on paddy rice, cotton, melons, fruits, forests and the like. According to the multi-component pesticide, the drug resistance of pests is avoided.

Description

Technical field [0001] The invention relates to a combined pesticide, in particular to a combined pesticide with a broad-spectrum insecticidal effect. Background technique [0002] Food, cotton, fruits, vegetables and other crops, forests, and trees have a wide range of diseases and insect pests. They are wide in scope, large in quantity and severely harmful. The world’s annual losses due to diseases and insect pests cannot be estimated. Conventional pesticides are used to prevent and control pests and diseases. One or two pesticides are used. There are more than 200 kinds of pests in the world. Different pests require different pesticides, and pests are resistant to commonly used pesticides, so the amount of single pesticides is increasing. . The effect of insect control and disease treatment is not significant. Summary of the invention [0003] The purpose of the present invention is to provide a combination pesticide with broad-spectrum insecticidal effect which has killing ...
