Problems solved by technology

Since the adjuvant of the product is a chemical adjuvant, which is toxic, and the insecticidal effect of the botanical insecticide is slow, the product has nothing special in the market. bug advantage
With the gradual withdrawal of highly toxic chemical pesticides from the market, the development of biological pesticides is imperative, but the botanical pollution-free surfactants (emulsifiers) that complement the pollution-free botanical insecticides are still rare.

Embodiment 1

[0046] Get 95 grams of natural pyrethrins with a content of 70% in Yunnan Subcritical Plant Co., Ltd. and add 5 grams of surfactants in the above-mentioned embodiment 14 to mix. Calculated in percentage by weight, the concentration of natural pyrethrins is 95%, and the active ingredient content is 66.5%. The preparation can be directly emulsified with water. Get 1 gram of it, mix it with water 400 times, and do a spray test on German cockroaches, which shows that the mortality rate is 100% within 8 hours.

Embodiment 2

[0048] In terms of weight percent W / W, transdermal agent 65%, sesame oil 8%, eugenol 27% prepared surfactant 5 grams and 95 gram pyrethrin former medicine are prepared 95% pyrethrin soluble preparation by weight concentration percentage, If the content of the original drug is 70%, then its active ingredient is 66.5%; if the content of the original drug is 50%, then its active ingredient is 47.5%. The two preparations were mixed with water 100 times respectively, and they had a quick killing effect on German cockroaches.

Embodiment 3

[0050] Get the former medicine of rotenone produced in Fengshun County, Guangdong and mix with botanical pesticide surfactant of the present invention, the results are as shown in table 4,

[0051] Preface

[0052] The above preparations mixed with water are excellent in emulsification, non-irritating to human skin, and non-polluting to the environment. They are used to kill cockroaches and die in about 48 hours, and have good effects in killing flower bugs and aphids.

Abstract

A surfactant able to dissolve, disperse and emulsify the vegetative insecticide (natural pyrethrin, nicotine, or rotenone contains proportionally percutaneous agent, vegetative oil and/or refined oil and extracts. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to the technical field of agricultural insecticides, in particular to a surfactant used for supporting the production of pollution-free pesticide emulsifiable concentrate. The invention also relates to the preparation method and application of the botanical pesticide surfactant. Background technique [0002] At present, the surfactants (emulsifiers), solvents, and additives used in chemical pesticide emulsifiable concentrates in my country are chemical preparations and chemical raw materials, such as toluene, xylene, methanol, etc., which more or less pose threats to human health and the environment. and pollution. At present, there are three major pollution-free pesticides, namely pyrethrin, nicotine, and rotenone products, but only pyrethrum is currently the only botanical insecticide that can be intensively produced. Because it is a natural substance, the most important feature of pollution-free pesticides is that they are saf...
