Biological fumigation synergistic composition, safe long-acting biological fumigation agent and application

Abstract

The invention relates to the technical field of biopesticides, and particularly discloses a biological fumigation synergistic composition, a safe long-acting biological fumigation agent and application, the biological fumigation synergistic composition is prepared from raw materials including allyl isothiocyanate and a synergist, the weight ratio of allyl isothiocyanate to synergist is (1.5-99): 1, the synergist is one or more of eucalyptol, ethylicin and sec-butyl acetate, and the synergist is added into the allyl isothiocyanate so that the pesticide effect of the allyl isothiocyanate is improved, and the biological fumigant has good use effect and safety. Meanwhile, the biological fumigant is prepared into a complexing agent, a soluble concentrate, an oiling agent, an emulsifiable concentrate preparation, a microcapsule suspending agent and the like so that the biological fumigant can be selected according to different occasions and has good stability and persistence.

Description

technical field [0001] This application relates to the technical field of biopesticides, more specifically, it relates to a synergistic composition for biofumigation, a safe and long-lasting biofumigant and its application. Background technique [0002] At present, the control of harmful organisms mainly relies on the control of chemical pesticides, such as the control of soil-borne diseases and insect pests, stored grain pests, archival cultural relics in storage rooms, goods in containers, and other open containers or containers. The drug resistance of these diseases and insect pests is constantly increasing, and these diseases and insect pests also have the characteristics of high concealment, so it is difficult to achieve ideal results by chemical control methods. For example, stored grain pest fumigants are commonly used in the prevention and control of storage diseases and insect pests. The stored grain pest fumigants react with aluminum phosphide and water to generate...

Problems solved by technology

[0002] At present, the control of harmful organisms mainly relies on the control of chemical pesticides, such as the control of soil-borne diseases and insect pests, stored grain pests, archival cultural relics in storage rooms, goods in containers, and other open containers or containers. The drug resistance of these pests and diseases is constantly increasing, and these pests and diseases are also characterized by high concealment, so it is difficult to achieve ideal results by chemical control methods

For example, stored grain pest fumigants are commonly used in the prevention and control of storage diseases and insect pests. The stored grain pest fumigants react with aluminum phosphide and water to generate phosphine gas, and use phosphine gas to fumigate pests. If the reaction between aluminum phosphide and water Inaccurate process control, if phosphine gas and oxygen are mixed to a certain ratio, there may be a risk of explosion

Moreover, with the long-term use of stored-grain pest fumigants, the pests have also developed higher resistance, resulting in the fumigation effect of the currently used stored-grain pest fumigants is not very satisfactory, and stored-grain pests will continue to cause damage

Due to the high toxicity of this type of chemical pesticides used, there are potential safety hazards in the production and use process, and there are also problems of residue and environmental pollution, and its application prospects are limited. Therefore, it is urgent to study a safe, long-acting, environmentally friendly Pesticides are extremely important
