Aqueous emulsion containing bamboo vinegar pesticide as well as preparation method and use thereof

Abstract

The invention discloses a bamboo vinegar contained pesticide aqueous emulsion which comprises the following components by weight: 1 to 20 percent of pyrethroid, 5 to 10 percent of organic solvent, 2 to 10 percent of emulsifier, 1 to 3 percent of dispersant, 1 to 5 percent of anti-freeze agent, 0.1 to 3 percent of thickening agent, 30 to 60 percent of bamboo vinegar and balance water. The pyrethroid is shown as a first equation, wherein R1 is a group as follows: Cl2 = CH-, (CH3)2C = CH-, Br2C = CH- or CF3ClC = CH-. The invention also provides a method for preparing the bamboo vinegar contained pesticide aqueous emulsion applied to the prevention of agricultural insects. The bamboo vinegar contained pesticide aqueous emulsion comprises the pyrethroid and the bamboo vinegar and accords with the quality requirements of agricultural preparations without on-site preparation, and moreover, the bamboo vinegar can improve the insecticidal action of the pyrethroid. Compared with the prior agricultural composition only comprising the pyrethroid, the invention achieves the same insecticidal action, decreases the effective ingredient consumption of the pyrethroid by about 50 percent and is non-toxic and pollution-free.

Problems solved by technology

[0004] Although it has been found that bamboo vinegar and cypermethrin have a synergistic effect in production, when bamboo vinegar is used for synergistic pesticides in the field, it can only be prepared on site, that is, it is prepared and used immediately, because bamboo vinegar and pesticides are compounded Afterwards, each active ingredient cannot exist stably, causing difficulties for practical application
