Embodiment 1

[0014] Example 1: Preparation of 1.8% rotenone-nicotine microemulsion (the following components are all percentages by weight)

[0015] Rotenone 0.5%

[0016] Nicotine 1.3%

[0017] Synergist 4.5%

[0018] Emulsifier 10%

Abstract

The invention discloses a preparation which is mixed by active composition of the plant source: rotenone and nicotine, belonging to the field of bio-pesticide. After being mixed, the rotenone and the nicotine have obvious synergistic action and overcome the shortages such as slow effect, short residual duration or narrow insecticidal spectrum or being greatly affected by the environment, and the like, of general bio-pesticide; the mixed preparation enlarges the control range of the preparation and the control spectrum; due to different mechanisms of two main agents, the pest is not easy to generate the resistance, thus delaying the pest resistance to insecticides; under the synergistic action of the mixed preparation, the actions of contact poison and stomach poisoning are obvious; the control effect is improved, the residual duration of the preparation is prolonged, the dosage of the preparation and the control cost are reduced; furthermore, the selected main preparation is the active composition of the plant source, thus having good environment compatibility, safety and no public harms.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a compounding of plant source rotenone and nicotine and its application as an insecticide. Background technique [0002] With the enhancement of people's awareness of environmental protection, the inherent limitations of chemical pesticides have become increasingly prominent, and the development of environmentally friendly pesticides has attracted much attention. The development of pollution-free pesticides has become an important trend in the sustainable development of agriculture; Slow effect, short residual effect period, or narrow insecticidal spectrum, or are greatly affected by the environment, etc., so it is difficult to be generally accepted by the market and meet the needs of agricultural production development. [0003] The mixing of botanical active ingredients with synergistic effects is an important research and development topic in the industry, because it can overcome the...
