Fume smoking sanitizer for sericultural production and preparing method thereof

Abstract

The invention discloses a fumigant disinfectant for sericulture production and a preparation method thereof, belonging to the technical field of disinfectants. The formula (by weight) of the fumigation disinfectant is: 25-60 parts of trichloroisocyanuric acid, 3-10 parts of chlorothalonil, 6-18 parts of combustion accelerant, and 7-20 parts of fire retardant. The product is fumigated with a dose of 5g / m3 for 5 hours, and can kill various pathogens of silkworms; fumigated with 0.5g / m3 for 30 minutes during the silkworm stage, the control effect on Beauveria bassiana and Aspergillus is better than Fangbing No.1. However, it has the same effect as the trichloroisocyanuric acid fumigant with a dosage of 1g / m3, and the drug cost can be reduced by about 50%. The labor force is reduced by more than 80%; the packaging of this product is reasonable, the shelf life is as long as two years, and the storage and transportation are also relatively safe. It can be used as a disinfectant for silkworm tools or silkworm seats in silkworm rooms.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, in particular to the technical field of fumigating disinfectant produced by sericulture and its preparation technology. Background technique [0002] To prevent silkworm diseases, it is necessary to do a good job in the disinfection of silkworm silkworm tools in the early stage and the disinfection of silkworm bodies and silkworm seats during the breeding process. Among them, the silkworm silkworm tools in the silkworm room are mainly disinfected with high-efficiency agents such as bleaching powder, and the silkworm silkworm seats are mainly used. Disease Prevention No. 1 for disinfection. The drug uses formaldehyde as the main agent, has the characteristics of high efficiency and broad spectrum, and has dual sterilizing effects in solid phase and gas phase. Although it has been popularized for nearly 30 years, it is still enduring. It is the first choice for disinfection of silkworm bodies...

AI Technical Summary

Problems solved by technology

At present, the fumigant disinfectants that are promoted in production are toxic and dissipate, sodium dichloroisocyanurate fumigant, sulfur, trichloroisocyanuric acid fumigant, etc. These medicines have their own characteristics, but there are also shortcomings, such as It is troublesome to dissipate the poison, and the effect is good when the room temperature is above 25°C. If the temperature of the furnace is not controlled properly, the polyoxymethylene will be incompletely volatilized, or it will burn on fire. The disinfection effect of the upper layer is better, while the disinfection effect of the ground and lower layers is poor; the fumigant of sodium dichloroisocyanurate is convenient to use, but there is also the floating of smoke, the disinfection effect of the middle and upper layers is good, while the disinfection effect of the ground and lower layers is poor Disadvantages, such as as a silkworm stage disinfection, the silkworm body and silkworm seats raised by ground silkworms cannot meet the disinfection requirements; sulfur is only effective against fungal spores, and it is troublesome to use; although trichloroisocyanuric acid fumigant is easy to use, it is not Both performance and efficacy are good, but because the main agent and auxiliary agent of this product are oxidizing agent and reducing agent respectively, it is very easy to absorb moisture after being mixed and packaged together. It is neither safe nor stable during storage and transportation. Available chlorine The decline is rapid, and the shelf life is only about half a year; in addition, in actual use, it is also found that although the fumigant has a good effect on the control of fungal diseases, its dosage is large and the cost of use is high
