Problems solved by technology

However, the drug has poor quick-acting properties and a large dosage, so it is generally not used alone.
[0004] Plant extracts are relatively less harmful to mammals and the environment. In order to adapt to the unfavorable factors of the natural environment, many plants produce substances that can inhibit pests and diseases, but a single plant

Abstract

The invention discloses antisepsis fresh keeping agent for the orange containing the tea saponin. The components have the weight percentages that tea saponin is of 0.01-80 percent, common orange antiseptic imazlil technical or prochloraz technical is of 0.5-80 percent, and the rest is assistant agent. The above components are mixed into emulsifiable concentrates, or wettable powder, or micro-emulsion, or suspending agent, or suspending emulsion, or emulsion in water, or soluble fluid. The invention lowers the fresh keeping cost as the medical effect is improved greatly, eliminates the toxicity of the chemical agent greatly, and has important significance for reducing the harm of the chemical agent on the environment and the human being, and for developing the vegetable extraction and the chemical agent mixture.

Description

technical field [0001] The invention relates to a class of antistaling agents, in particular to a medicament for post-harvest antiseptic and antistaling citrus, in particular to an antistaling agent mixed with tea saponin and commonly used citrus antiseptics. Background technique [0002] Post-harvest preservation of citrus and other fruits is a global problem, especially the maintenance of the quality of fruits and vegetables during storage. Treating with preservatives before storage can kill pathogens, control the growth of latent pathogens, regulate the physiological metabolism of fruits to a certain extent, maintain the quality of fruits, and prolong the storage period. Our country started relatively late in the research on diseases of fruit and vegetable storage and transportation. In the 1970s, with the development of the fruit and vegetable storage and transportation industry, it began to attract attention. In the early days, fruits and vegetables were usually soaked ...
