Efficient sugarcane insecticidal composition and prevention and treatment method

Abstract

The invention provides an efficient sugarcane insecticidal composition which comprises the following components in parts by weight: 50-70 parts of an insecticide, 20-30 parts of an attractant and 10-20 parts of a film-forming agent; the insecticide comprises an amide insecticide, a neonicotinoid insecticide, a pyrethroid insecticide and a biological source insecticide; the attractant is prepared from limonene and monosultap; the film-forming agent comprises a modified chitosan base which can improve the adhesion of the pesticide fertilizer to sugarcane, so that the pesticide property of the pesticide is prolonged, the utilization rate of the pesticide is improved, and meanwhile, the prevention and control and treatment effects on pests can be greatly improved; the application method comprises the following steps: 1) spraying sugarcane seeds and soil in furrows for the first time when the sugarcane seeds are sown; (2) applying the fertilizer during small hilling and topdressing of the sugarcane, and uniformly spraying on sugarcane stems and sugarcane leaves; the pesticide effect can be improved, pesticide is applied according to indications, sugarcane seeds and soil in ditches are fundamentally protected, pests are restrained, fertilization is conducted again in the mature period, sugarcane stems and sugarcane leaves are evenly sprayed, and therefore the surfaces of the sugarcane stems and the surfaces of the sugarcane leaves are evenly covered with films, and efficient prevention and control and treatment are achieved.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a high-efficiency sugarcane insecticidal composition and a control method. Background technique [0002] Sugarcane is the most important sugar crop and energy crop in my country, and it is an upstream product in the fields of medicine, low-carbon industry, and food. my country is one of the main sugar producing and consuming countries. The perennial sugarcane planting area reaches 22 million mu, accounting for more than 85% of sugar crops, and more than 90% of the total sugar production comes from sucrose. The development of the sugarcane industry not only directly affects the income and life of tens of millions of sugarcane farmers, but also has a bearing on the national sugar supply security. Sugar products are not only the rigid needs of human survival, but also important raw materials for the production of related enterprises, such as beverage and food production ...

AI Technical Summary

Problems solved by technology

[0003] For a long time, due to backward sugarcane cultivation technology, unreasonable fertilization and pesticide application, and inadequate control of diseases and insect pests, the yield of sugarcane has been limited. Especially in recent years, due to the impact of human disturbance on the natural environment, the ecosystem of sugarcane growth has been destroyed. Rising temperature, soil erosion and other factors have caused a series of problems such as serious pests and diseases

[0004] At present, sugarcane planting in production mostly adopts traditional planting methods, that is, the mixed application of monomer fertilizers (urea, superphosphate, potassium chloride), and then spraying granular pesticides to prevent insects, etc., is time-consuming and laborious, and the pesticides have a short period of efficacy. Cannot effectively control the harm of sugarcane borer, aphids, stem borers, cotton aphids, etc. in the middle and later stages of sugarcane, resulting in low sugarcane yield and low sugar content

At the same time, there are unreasonable fertilizer application and low fertilizer utilization, especially in high temperature or rainy weather, serious loss of fertilizer and medicine, resulting in waste of resources, and cannot prevent and treat pests.
