Compound pesticidal granule containing chlorpyrifos and phoxim

Abstract

The invention relates to the field of pesticides for preventing and controlling agricultural pests, and in particular relates to a compound pesticidal granule containing chlorpyrifos and phoxim. The compound pesticidal granule containing chlorpyrifos and phoxim disclosed by the invention is prepared by compounding the following materials in parts by weight: 2 to 4 parts of chlorpyrifos, 10 to 12 parts of phoxim, 40 to 45 parts of humic acid, 15 to 18 parts of activated carbon, 20 to 22 parts of potato flour, 10 to 12 parts of bamboo vinegar and 28 to 32 parts of bran. The materials in the pesticidal granule prepared by the invention are convenient to obtain, the pesticidal granule does not pollute the environment, economics is good, and after being applied, the pesticidal granule is easy to degrade, and does not harm the human being and animals, does not pollute the environment and remain in mature peanuts.

Description

technical field [0001] The invention relates to the field of insecticides used for the control of agricultural pests, in particular to a compound insecticide granule containing chlorpyrifos and phoxim. Background technique [0002] Peanut is the main raw material of people's edible oil. With the improvement of people's living standards, the demand for peanut oil is increasing, and special attention should be paid to whether it has pesticide residues. In the process of peanut production and planting, it is inevitable to use some insecticides To ensure the high and stable yield of peanuts, to meet the growing material needs of the people, however, in the process of peanut cultivation, often due to improper use of drugs, there are too many pesticide residues in peanut fruits, which are not easy to eat, and may cause poisoning in severe cases. One of the important reasons for the continuous increase in peanut production in the United States is the general prevention and control ...

AI Technical Summary

Problems solved by technology

This method proposes a simple, efficient and precise new technology for preventing and controlling peanut pests and weeds, which solves the problems of time-consuming, laborious, and drug-consuming, and the effect is not obvious in the process of peanut pests and weeds prevention, improves peanut production efficiency, and increases farmers' planting costs. enthusiasm

[0003] At present, there are mainly four methods for preventing and controlling peanut underground pests in my country. These methods all have certain problems: the first method is to mix insecticides into powdery carriers to make insecticidal powders, which are easy to lose after being applied to the soil and have long-lasting effects. The period is relatively short, and it is easy to be inhaled by the human body during use, causing physical harm; the second is to use sand as the pesticide carrier to make granules. Due to the poor adsorption of pesticides by sand, it is easy to lose after being applied to the soil. Short; the third is to use insecticide seed dressing, which can effectively prevent and kill underground pests, but often affects seed germination; the fourth is to directly spray insecticides in the soil to kill soil pests. Waste of pesticides, pollute the environment, the control effect is not significant

Patent CN1539284A discloses a compound insecticidal granule of chlorpyrifos and phoxim, using sand, ore, and coal gangue as the carrier, which is the second case mentioned above, and it is easy to lose after driving into the soil, and the duration is short

[0004] In recent years, due to the repeated use of a large number of highly toxic pesticides and single preparations, some pests have developed resistance or increased resistance. At the same time, due to the use of a large number of highly toxic pesticides, the amount of pesticide residues in peanuts will exceed the standard, which will directly affect people's consumption health and even my country's peanut export earnings
