Abstract

The invention relates to a disinfectant for silkworms and application thereof and belongs to the technical field of prevention and control of mulberry silkworm diseases. The disinfectant for the silkworms is prepared from the following raw material components in parts by weight: 1 to 20 parts of fludioxonil, 1 to 15 parts of propamocarb hydrochloride and 10000 parts of water; all the raw materialcomponents are uniformly mixed to prepare the disinfectant; the disinfectant can be used for disinfecting silkworm rearing tools and silkworm rearing beds of silkworm rearing rooms. According to the disinfectant for the silkworms, the fludioxonil and the propamocarb hydrochloride are mixed to prepare the disinfectant for the silkworms for the first time; the fludioxonil and the propamocarb hydrochloride are combined to use and have a cooperative promotion effect of killing beauveria bassiana of domestic silkworms, and the killing effect is improved; the disinfectant for the silkworms is safe and efficient and has no teratogenesis, mutagenesis and carcinogenesis effects on animals, so that the disinfectant belongs to an environment-friendly type disinfectant with a safe ecological environment.

Description

technical field [0001] The invention relates to a disinfectant for silkworms and an application thereof, belonging to the technical field of silkworm disease prevention and control. Background technique [0002] my country is the world's high-quality raw material cocoon production base, and its export volume accounts for more than 80% of the world's total. The direct economic losses caused by silkworm diseases in sericulture production account for about 10-15% of the total income. Beauveria muscadicus is one of the main diseases in silkworm cocoon production, and the occurrence of diseases has brought great losses to silkworm cocoon production. [0003] Chlorine preparations such as bleaching powder and dichloroisocyanuric acid and aldehyde preparations such as formaldehyde are widely used in the prior art. Chinese patent document CN101233853 (application number 200810020439.5) provides a compound disinfectant for silkworms used for disinfection of silkworm seats and silkwo...
