Chlorpyrifos-containing pesticide controlled release thermal insulation material

Abstract

The invention discloses a chlorpyrifos-containing pesticide controlled release thermal insulation material and belongs to the technical field of pesticide controlled release thermal insulation materials. The chlorpyrifos-containing pesticide controlled release thermal insulation material is composed of the following components in percentage by weight: 1-10% of chlorpyrifos, 0.1-25% of auxiliary, 50-90% of carriers and 0.1-25% of regulator. The chlorpyrifos-containing pesticide controlled release thermal insulation material disclosed by the invention is used for the coverage operation of a bamboo shoot land and is capable of preventing and treating pests under the bamboo shoot land, is good in prevention and control effects, long in lasting period in soil and capable of avoiding the condition that the food safety is affected by pesticide residue in bamboo shoots; in addition, the chlorpyrifos-containing pesticide controlled release thermal insulation material can be used for achieving heat preservation and moisture retention control effects on the bamboo shoot land, accelerating the growth of the bamboo shoots and the shoot emergence of the bamboo shoot land and generating a better economic benefit.

Description

technical field [0001] The invention belongs to the technical field of pesticide slow-release thermal insulation materials, in particular to a pesticide slow-release thermal insulation material containing chlorpyrifos. Background technique [0002] my country is the world's largest producer of bamboo shoots. With the rapid expansion of the cultivation area of ​​bamboo shoots and the improvement of intensive management, the damage caused by diseases and insect pests in bamboo gardens is increasing day by day. In particular, the promotion of mulching management technology (covering the soil surface with other thermal insulation materials), while accelerating the emergence of bamboo shoots through thermal insulation to generate significant economic benefits, also provides a good habitat for underground pests to overwinter due to thermal insulation, which is likely to cause pest outbreaks in the next spring. Therefore, in the cultivation of bamboo shoots, the conventional method...

AI Technical Summary

Problems solved by technology

However, due to the interception effect of the covering material on rainwater, the amount of water in contact with the granules is small. This leaching migration process is too slow and the amount is small, so that the time when the pesticide enters the lower layer has missed the critical period for the hatching of underground pests. , and the insufficient amount is difficult to play a good control effect on adults

The most critical thing is that the time when pesticides enter the lower layer is exactly the peak period of spring bamboo shoots, which increases the risk of pesticides entering bamboo shoots through absorption from the soil near the root whip

Moreover, the currently used pesticide granules contain certain guest soil components, which can easily bring heavy metals, nitrates, pesticides and other pollutants into the bamboo shoots, thereby polluting the bamboo shoot soil and posing a potential threat to the quality and safety of bamboo shoots. ; and may introduce alien organisms, which will have an impact on the soil biological community of the relatively closed bamboo shoot forest, and further affect the long-term management benefits of the bamboo shoot field
