Embodiment 1

[0039] Mix 100 g Spodoptera litura nuclear polyhedrosis virus (10 billion PIB / g), 50 g polymer emulsifier N-300, 200 g polyoxyethylene sorbitan ester, 80 g soybean oil, 3 g propylene glycol, 1 g hydroxymethyl cellulose , 2g organosilicon, add distilled water to 1000g, fully stir and make Spodoptera litura nucleopolyhedrosis virus aqueous emulsion 01-A of 1 billion PIB / ml.

Embodiment 2

[0041] Add 100 g of Spodoptera litura nuclear polyhedrosis virus (10 billion PIB / g), 250 g of polyoxyethylene sorbitan ester, 80 g of soybean oil, 3 g of propylene glycol, 1 g of hydroxymethyl cellulose, and 2 g of silicone, and add distilled water to 1000 g , the Spodoptera litura nuclear polyhedrosis virus aqueous emulsion 01-B of 1 billion PIB / ml was prepared.

Embodiment 3

[0043] Add 10 g of G-100A to 100 g (1 billion CFU / g) of the bacterial suspension of Bacillus subtilis and stir well to obtain the aqueous phase of the bacterial liquid. Add 30g of alkyl polyglycol ether to 200g of peanut oil and stir well. At the same time, add the water phase of the bacterial solution, stir well, add distilled water to 1000g, and obtain 100 million CFU / g Bacillus subtilis water emulsion 02-A.

Abstract

The invention relates to a polymer emulsifier for resisting decomposition of biopesticides in an emulsion in water (EW), and application of the polymer emulsifier. The polymer emulsifier is any one ora composition of two of a polymer emulsifier N-300 or G-100A produced by Shantou Daqian High-tech Research Center Co.Ltd.. The invention further provides application of the polymer emulsifier for resisting decomposition of the biopesticides in the EW, and the EW containing the polymer emulsifier. The polymer emulsifier lowers high-temperature decomposition, strong light decomposition or ultraviolet light decomposition of the biopesticides in the EW; that the polymer emulsifier N-300 or G-100A can decrease the decomposition rate of the biopesticides in the EW is discovered by the invention, especially for the EW prepared from viral biopesticide, bacterial biopesticide, fungus biopesticide, microbial metabolite biopesticide and the plant extract biopesticide, and the emulsifier provided byinvention greatly decreases the decomposition rate.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to adjuvants for pesticide preparations, in particular to a polymer emulsifier for biopesticide decomposition in water-resistant emulsions and its application. Background technique [0002] Biopesticides have an incomparable effect on traditional pesticides. When traditional pesticides are used too much, many pests and diseases develop resistance, and the resistance is getting stronger and stronger. Therefore, traditional pesticides are difficult to control pests and diseases, while biopesticides have low toxicity, no residue, The characteristics of slow action and long duration show relatively excellent crop protection effects. In addition, biological pesticides are harmless to humans, animals, and plants, and will not pollute the environment. [0003] However, the disadvantages of biopesticides are also obvious. For example, the control effect of biopesticides is generally sl...
