Phosphine and ethyl formate mixed synergist and application thereof

Abstract

The invention discloses a phosphine and ethyl formate mixed synergist for treating and killing pests carried by fresh agricultural products, and belongs to the technical field of application of fumigant mixing synergistic technology to pest control. According to the invention, the ratio of two fumigants and the fumigation temperature are mainly controlled to achieve an optimal synergistic effect, the usage amount of a single fumigant is effectively lowered, the defects that the phosphine treatment time is too long, the insecticide resistance is likely to generate, the quality of fresh agricultural products is prone to damage, the ethyl formate treating adsorption is overlarge, the dosage of ethyl formate is over high and the like are overcome, the operation is simple and convenient, and the application is easy. The phosphine and ethyl formate mixed synergist can be used for effectively preventing harm and propagation of fruits, vegetables, seedlings, flowers and the like carrying pests and keeping the quality of fresh agricultural products. A method with the phosphine and ethyl formate mixed synergist has the characteristics of high efficiency, economy, environment friendliness and the like, and is pest control technology capable of effectively replacing methyl bromide fumigation.

Description

technical field [0001] The invention relates to the detoxification treatment of quarantine harmful organisms carried by fresh and live agricultural products, in particular to the application of a synergistic formulation of two fumigants, phosphine and ethyl formate, on fresh and live agricultural products such as fruits, vegetables, seedlings and flowers. Background technique [0002] After joining the WTO, my country's trade in agricultural products has grown rapidly, with the total import and export volume reaching US$185.08 billion in 2013. With the continuous deepening of globalization, the goods, personnel, and postal items between my country and the rest of the world are growing at a high speed, and the country's ecological environment, public health and other national security risks have increased significantly. In 2013, my country intercepted 607,622 harmful organisms. Among them, there were 335 kinds of quarantine pests and 53,405 times. The effective prevention a...

AI Technical Summary

Problems solved by technology

[0007] We have developed a fumigant mixed dosage form, which has a good synergistic effect compared with a single fumigant, and can effectively reduce the tolerance of harmful organisms to phosphine and ethyl formate alone, and is effective under relatively mild conditions Kill harmful organisms, avoiding the disadvantages of too long phosphine treatment time and damage to the quality of fresh agricultural products, and the use of ethyl formate is too high. It is suitable for post-harvest fresh plant products such as fruits, vegetables, seedlings and flowers. Disinfection treatment
