Description

High-efficiency insecticide and fungicide containing R-diniconazole and chlorantraniliprole

technical field

The invention belongs to the field of chemical prevention and control of rice diseases and insect pests, and specifically relates to a high-efficiency insecticidal and bactericidal compound agent containing R-diniconazole and chlorantraniliprole, which is mainly used for preventing and treating rice sheath blight, rice blast, rice false smut and rice smut. It can be used for the prevention and control of various rice diseases and insect pests such as leaf roller, rice stem borer, rice stem borer, and rice borer, and can also be used for the prevention and control of various diseases and insect pests on cotton, wheat, corn and other crops.

Background technique

Rice sheath blight and rice blast have always been important diseases during the rice growth period, causing serious losses all year round. In recent years, the occurrence of rice smut has been on the rise in Anhui, Hubei, Jiangsu and other rice-growing areas, which has also caused serious yield loss and seriously affected rice quality. The rice leaf roller, the rice stem borer, the rice stem borer, and the rice stem borer are several kinds of pests that are more serious in the rice growth period, among which the rice leaf roller [Cnaphalocrocis medinalis (Guenee)] is a migratory pest , which occurs in every rice area in my country. It is one of the main pests of rice due to its strong suddenness and wide damage area, and it causes the reduction of rice production all the year round. For a long time, people have been committed to the research on the control of rice sheath blight, rice blast, rice leaf roller, rice stem borer, rice stem borer and rice borer, and the control of rice false smut has become more and more a hot spot in recent years. .

Chlorantraniliprole is an o-formamidobenzamide insecticide with high efficiency and broad spectrum. It can control various non-Lepidoptera pests such as Coleoptera, Lepidopteridae, Chrysoopteridae, Diptera Liminidae and Bemisia tabaci, especially for Lepidoptera. The effect of the target pests is indeed very good, and the control time is very long. Its mechanism of action is mainly to activate ryanodine receptors, release calcium ions stored in smooth muscle and striated muscle cells, cause muscle regulation weakness, paralysis, and finally the death of pests. At the same time, chlorantraniliprole shows a very significant selectivity difference between mammals and pest ryanodine receptors, which greatly improves the safety of mammals and other vertebrates.

R-diniconazole is a triazole fungicide, which inhibits 14α-demethylation in the ergosterol biosynthesis of fungi, causing ergosterol deficiency, resulting in abnormal fungal cell membranes, and eventually fungal death, with a long-lasting effect. Safe for humans, animals, beneficial insects, and the environment. It is a broad-spectrum fungicide with protective, therapeutic and eradicating effects; it has special effects on various plant diseases caused by cystic fungi and basidiomycetes, such as powdery mildew, rust, smut, and scab. In addition, it also has a good control effect on diseases caused by Cercospora, Sclerotinia, Sclerotinia, Sclerotinia and Rhizoctonia.

The combination of chlorantraniliprole and R-diniconazole focuses on the control of major diseases and insect pests in the middle and late stages of rice. Taking rice leaf roller, rice stem borer, rice stem borer and other pests as well as diseases such as sheath blight, rice koji and rice blast as the control targets, the control spectrum of crop pests has been expanded. It has achieved multi-drug treatment and multiple diseases and insect pests, reducing the number of pesticide applications, which can effectively reduce the cost of pesticide application for crop pest control, and reduce the difficulty of farmers' choice of pesticides. The combination of chlorantraniliprole and R-diniconazole is beneficial to farmland organisms and environmental safety, improves the control effect of natural enemies, and protects the good ecological environment of farmland.
