Problems solved by technology

[0005] The extraction process of chelerythrine has been studied for many years. At present, the extraction process of chelerythrine is mature, but the research on its dosage form is less or relatively lagging behind, and more emulsifiable concentrate formulations are used in current agricultural production. do not give new fixed point

Abstract

The invention discloses a biological bactericide chelerythrine suspending agent and a preparation method thereof. The biological bactericide is mainly prepared from chelerythrine, sodium lignin sulfonate, sodium dodecyl benzene sulfonate and glycol in a certain weight ratio. The biological bactericide has a high-efficiency bactericidal and disease preventing properties, and is wide in application range and good in effect for controlling crop diseases and pests.

Description

technical field [0001] The invention relates to a biopesticide fungicide, in particular to a chelerythrine suspension and a preparation method thereof. technical background [0002] Most of the fungicides currently produced in my country are old varieties such as organophosphorus, substituted benzenes, organosulfurs, benzimidazoles and triazoles. Due to the long-term use of these traditional old varieties, many varieties have developed high resistance, and they are only effective when used in large doses, resulting in excessive pesticide residues in agricultural products. Especially in some large-tonnage varieties currently on the market, such as triadimefon, carbendazim, etc., some have serious resistance problems, and some have poor or ineffective control effects, which can no longer meet market demand. Therefore, it is imperative to vigorously develop new varieties and new formulations of highly efficient and safe biocides. [0003] Chelenerythrine is a product extracte...
