Problems solved by technology

For a long time, people have mainly used chemical drugs to kill rodents and achieved good results. However, chemical drugs have defects such as polluting the environment, endangering the natural enemies of rodents, and posing a threat to the safety of humans and animals. Using a single bait variety, the problem of rat refusal to eat gradually appeared, which affected the effect of eradication to a certain extent

Abstract

The invention discloses a grass meal granular formulation for controlling rodent pests in grassland and a preparation method as well as application thereof. The preparation method comprises the following steps of: preparing a neem seed extractive, then manufacturing the neem seed extractive, grass meal granules and an auxiliary material into the granular formulation according to a certain proportion, wherein the mass proportion of the neem seed extractive, the grass meal granules and the auxiliary material is 2-4:2-4:1-2. The preparation technology provided by the invention is simple, reliable and easy to control; and the prepared grass meal granular formulation is fragrant in flavor, has the good palatability and obvious anti-fertility effect on male and female plateau pika and is a novel botanical bisexual sterility rodenticide for controlling the rodent pests in the grassland.

Description

technical field [0001] The invention relates to a grass powder granule for preventing and controlling grassland rodent damage, a preparation method and application thereof, in particular to a grass powder granule with asexual sterility and a preparation method and application thereof. Background technique [0002] Prairie pests mainly include Ochotona curzoniae, Myospalax baileyi, Microtus fuscces, Eothenomys inez, E.proditor, and plateau white-bellied rat There are more than 10 species including Niviventer coninga, Marmeta himalayana, Apodemus chevieri, and Ochotana thibetana. They like to eat pasture, grain and other crops, which is an important reason for the serious degradation of grassland, black soil beach and grassland desertification in my country's "Three River Source Area", which seriously affects and restricts the animal husbandry production in the Qinghai-Tibet Plateau area and the survival and development of the majority of farmers and herdsmen. and spread disea...
