Problems solved by technology

The main solvent in the existing rotenone or rotenone and phoxim compounded emulsifiable concentrate is toluene or xylene (both of which contain a small amount of benzene), which are highly toxic to mammals (benzene is a blood poison and has a strong cytogenetic Toluene and xylene mainly affect the function of the nervous system of the contact person. Long-term exposure to benzene series may cause blood pressure increase and leukopenia, which will affect the reproductive function of the contact person and have developmental toxicity) , serious environmental pollution, and the defects of consuming a large amount of resources (the processing of emulsifiable oil in my country consumes 250,000 tons of organic solvents worth 750-900 million yuan per year), and benzene series solvents are facing a trend of being banned in developed countries, especially in The use of conventional (using benzene series as solvent) emulsifiable concentrates on vegetables and fruit trees has been strongly resisted, thus prompting the continuous updating and development of pesticide preparations
Based on the above problems to be solved in conventional emulsifiable concentrate formulations, most experts in the pesticide industry proposed that the future processing of pesticide formulations should be water-based, such as processing into suspension concentrates, water-dispersible granules, microemulsions, water-emulsions, and microcapsules. Suspending agent, etc., but these water-based formulations have relatively strict requirements on processing equipment and processing technology, which is not conducive to the current many old pesticide companies producing EC in my country to get rid of the capital and technical bottlenecks caused by the production ban of conventional EC in the near future. dilemma

Embodiment 10

[0021] Example 10 Toxicity comparison between vegetable oil-based insecticide and acaricide and conventional emulsifiable concentrate on Panonychus citrus

[0022] With reference to the glass slide dipping method recommended by FAO, measure the toxicity of 2.5% vegetable oil-based rotenone insecticide and acaricide (embodiment 1) and conventional emulsifiable oil to Panonychus citrus, and the two medicaments are diluted into pre-tested 50% respectively with tap water. Each concentration was repeated three times, and at least 30 female adult mites were repeated for each repetition. The test mites were immersed in the liquid medicine of each concentration for 5 seconds, and the remaining liquid medicine around the mites were quickly blotted with filter paper. After the treatment was completed, the test mites were Place them in a biochemical incubator with T=(25±1)°C, RH=(60±10)%, L:D=14:10, and clean water as the control. Result (see table 2) shows, this vegetable oil-based inse...

[0024] Example 11 Comparison of toxicity of vegetable oil-based rotenone and phoxim compound insecticide and acaricide to third instar larvae of Spodoptera litura

[0025] Measure the toxicity of 18% vegetable oil-based rotenone and phoxim compound insecticide and acaricide (embodiment 6) and conventional emulsifiable oil to 3 instar Spodoptera litura larvae with blade dipping method, two medicaments are diluted respectively with tap water The 5 concentrations tested, each concentration was repeated three times, and at least 10 test insects were repeated for each repetition. Fresh non-toxic cassava leaves were dipped in each concentration of medicinal solution for 5 seconds. After the treatment was completed, the test insects were placed at T=(25±1)°C , RH=(60±10)%, cultured in a biochemical incubator with L:D=14:10, and the control was clear water. The results (see table 3) show that the toxicity of this insecticide and acaricide to 3 instar Spodoptera litura larvae is signif...

Embodiment 12

[0027] Example 12 Toxicity comparison of vegetable oil-based rotenone and phoxim compound insecticide and acaricide and conventional EC against radish aphid

[0028] Take the potter spray method to compare the toxicity of 18% vegetable oil-based rotenone and phoxim compound insecticide and acaricide (embodiment 6) and conventional emulsifiable oil to the radish aphid, and the two medicaments are diluted into 5 pre-tested aphids respectively with tap water. Concentration, each concentration was repeated three times, each repetition was at least 30 aphids without wings, each treatment was sprayed with 1mL of liquid medicine on the front and back sides of the leaves, and after the treatment was completed, the test insects were placed at T=(25±1)°C, RH=(60 ±10)%, cultured in a biochemical incubator with L:D=14:10, and the control was clear water. The results (see table 4) show that the toxicity of the insecticide and acaricide to the radish aphid is significantly higher than that ...

Abstract

The invention discloses a vegetable oil based insecticidal acaricide, which comprises (by weight percent) gum spirit of turpentine 5-75%, wintergreen oil 0-55%, elliptone 0.01-5%, and balancing adjuvant.

Description

technical field [0001] The invention relates to the field of agricultural insecticides, in particular to a vegetable oil-based insecticide and acaricide. Background technique [0002] Rotenone is a well-known selective botanical insecticide and acaricide, which has good effects on hundreds of agricultural and sanitary pests, especially in recent years, it has played an important role in the control of resistant pests (such as diamondback moth). It is an ideal drug. Phoxim is a high-efficiency, broad-spectrum, low-toxic insecticide and acaricide, which can effectively control pests and mites on rice, tea, fruit trees, vegetables, cotton and other crops. The main solvent in the existing rotenone or rotenone and phoxim compounded emulsifiable concentrate is toluene or xylene (both of which contain a small amount of benzene), which are highly toxic to mammals (benzene is a blood poison and has a strong cytogenetic Toluene and xylene mainly affect the function of the nervous sys...
