Embodiment 1

[0017] After crushing 5kg of the stems and leaves of Eupatorium adenophorum collected in the field, add 5kg of ethanol (containing more than 95%), soak for 7-10 days, stir twice a day during the soaking period, filter and squeeze dry together with the soaking material to obtain the filtrate About 8-9kg, concentrated under reduced pressure, dehydrated to 4-5kg is "euplinin".

[0018] The following is a comparison table of the insecticidal effect of "Euplinin" and several insecticides alone and according to the 3 / 7 and 5 / 5 ratio tests.

Abstract

The invention relates to phytochemical pesticide synergistic agent. The pesticide synergistic agent takes compositae ill weeds eupatorium adenophorum as raw material. The eupatorium adenophorum is dipped in definite organic solvents for 7 to 10 days, and then is squeezed to get extract which contains 'euparin'. The euparin is added in to chemical pesticides by volume percent of 1-95%, has obvious synergies. When the control efficiency is same, the phytochemical pesticide synergistic agent can reduce the use of pesticides by 30-60 %, reduce the negative effects of pesticides on environment, reduce the use cost of pesticides, and reduce the burden of farmers. The ill weeds eupatorium adenophorum is used as raw material, which controls ill weeds eupatorium adenophorum and changes waste to valuable, thus increasing the income of hill farmers.

Description

Technical field [0001] The present invention relates to agricultural insecticides, in particular to a plant-derived insecticide synergist that can improve the efficacy of known insecticides. Background technique [0002] The development and application of plant-derived pesticide synergists can open up another way for the future research of plant-derived pesticides at home and abroad, and can also complement each other's strengths and weaknesses between plant-derived pesticides and fine chemical pesticides, and find a scientific win-win approach. The new plant-derived active substance mixed with high-efficiency and low-toxic pesticides can be widely used for pest control of vegetables, fruits, tea and food crops after obtaining pesticide product registration. [0003] In order to reduce the environmental pollution caused by chemical pesticides, all countries have invested heavily in pesticide development: A. Development of new high-activity, low-toxicity, and low-residue pesticide...
