Abstract

The granular pesticide preparation for preventing and controlling smaller brown planthopper in wheat field consists of chlorpyrifos, DDVP, stabilizer A, stabilizer B, colorizing agent and carrier in certain weight proportion. The stabilizer A is butyrolactone, gamma-propiolactone or delta-propiolactone; the stabilizer B is 1, 2-butanediol, 2-methyl-2, 4-pentanediol or [1, 5]-pentanediol; the colorizing agent is red powder, phthalocyanine red or acid scarlet; and the carrier is coal slack, perlite or vermiculite. The granular pesticide preparation as re-compounded pesticide has synergistic effect of killing smaller brown planthopper and other effect.

Description

Technical field [0001] The invention relates to a pesticide for preventing and controlling Laodelphax striatellus, in particular to a granule for preventing and curing Laodelphax striatellus in wheat fields. Background technique [0002] In recent years, Laodelphax striatellus has been rampant in my country's rice-wheat rotation areas, leading to large outbreaks of rice stripe leaf blight spread by it as a vector, resulting in reduced rice yields and reduced rice quality. [0003] Laodelphax striatellus can survive the winter in most areas of my country. After the late autumn rice is harvested, it is mainly moved into wheat fields for overwintering. In the second year, the wheat is harvested and then moved into seedling fields or early-planted rice fields to damage rice and spread stripe leaf blight virus. In addition to factors such as climate, crop varieties and farming systems, another major cause of Laodelphax striatellus outbreaks is resistance to the past special drug imida...
