Problems solved by technology

[0004] The purpose of the present invention is to overcome the technical problem of spraying chemical pesticides on plants in the above-mentioned prior art, which is easy to be washed away by rainwater and cannot play a real control effect on pests, and to provide a ring-shaped pesticide slow-release agent. The slow-release agent is elastic, and it can slowly release insecticidal active ingredients when it is bound to the plant in a humid environment or rainwater leaching conditions. It has a good control effect on diseases such as corn ear rot and pests such as fall armyworm, and protects food. Production safety

Abstract

The invention discloses an annular pesticide slow-release agent which comprises an elastic ring, and the elastic ring comprises the following raw material components in percentage by weight: 0.1-2.0%of a pesticide active agent, 1-10.0% of an organic solvent, 2.15-6.7% of a slow-release material, 5-20.0% of plant essential oil, 0.1-0.5% of an emulsifier, 0.01-0.05% of an organic acid and the balance of water. Wherein the slow-release material comprises chitosan, sodium alginate, carboxymethyl chitosan, sodium tripolyphosphate and calcium chloride. The annular pesticide slow-release agent slowly releases pesticide active ingredients in a humid environment or under a rainwater leaching condition, has a good prevention and control effect on diseases such as corncob rot and pests such as grassland spodoptera litura, and can remarkably improve the insecticidal prevention and control effect, reduce the pesticide dosage and prolong the pesticide prevention and control time, so that the grainproduction safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a ring-shaped pesticide slow-release agent and its preparation method and application. Background technique [0002] Spodoptera frugiperda, also known as fall armyworm, belongs to Lepidoptera, Noctuidae, and Spodoptera genus. It is an omnivorous pest native to tropical and subtropical regions of America. Its larvae can feed on corn, sugarcane, sorghum and Millet and 353 species of plants in 76 families have spread and spread in many countries. Huge damage was done in Brazil and Africa. Since the invasion in 2019, noctuid moths have been found in 25 provinces and municipalities in my country, covering an area of ​​more than 15 million mu and actually damaging an area of ​​2.68 million mu. Studies have found that the habit of Spodoptera frugiperda gathering on the ears of corn to feed and cause damage not only causes direct yield loss, but also mixes its granular excrement bet...
