[0023] The preparation method of the above-mentioned novel crop insect-proof, mildew-proof and insect-repelling emulsion comprises the following steps:
[0024] (1) Heat 2-5 parts of jatropha fruit oil and 3-7 parts of Tween 40 at 60-80°C, and stir for 20-30 minutes;
[0025] (2) 1-5 parts of cinnamon essential oil, 10-15 parts of Melaleuca alternifolia essential oil, 1-5 parts of eucalyptus essential oil, and 10-15 parts of water are mixed in proportion and added to the Jatropha curcas in step (1) In the mixture of oil and Tween, stir for 30-60 minutes and homogenize to make a high-concentration water-soluble emulsion.
[0026] The above-mentioned emulsion is applied to prevent insects, mildew and repel insects of crops. When in use, blend the emulsion with room temperature water at a volume ratio of 1:1000-10000.
Embodiment 1
[0029] (1) 2 parts of squeezed jatropha oil, 3 parts of Tween 40 (polysorbate-40) were stirred and mixed and heated at 60° C. for 20 minutes.
[0030] (2) Then, 10 parts of Melaleuca alternifolia plant essential oil, 1 part of eucalyptus essential oil, and 1 part of cinnamon essential oil with tea tree oil component 4-terpineol content refined by molecular distillation are mixed and then added to step (1) In the mixed solution, heat it to 60°C with a water bath and stir for 30 minutes, add 10 parts of water and continue stirring for 20 minutes, and homogenize the mixed solution under high pressure with a pressure of 20 MPa. After homogenization, high-concentration water-soluble insect-proof, anti-mold and insect-repelling emulsions are made.
[0031] When used, the emulsion is blended with normal temperature water at a ratio of 1:1000.
Embodiment 2
[0033] (1) 5 parts of squeezed jatropha oil and 7 parts of Tween 40 (polysorbate-40) were stirred and mixed and heated at 60° C. for 20 minutes.
[0034] (2) Then 15 parts of Melaleuca alternifolia plant essential oil, 5 parts of eucalyptus essential oil, 5 parts of cinnamon essential oil of the tea tree oil component 4-terpineol content 40% that utilize molecular distillation to refine are mixed, then add step (1 ) in a water bath and heated to 60° C., stirred for 30 minutes, added 15 parts of water and continued to stir for 60 minutes, and the mixed solution was homogenized under high pressure with a pressure of 30 MPa. After homogenization, high-concentration water-soluble insect-proof, anti-mold and insect-repelling emulsions are made.
[0035] When used, the emulsion is blended with normal temperature water at a ratio of 1:10000.
