It is prepared by dissolving a water-insoluble original drug with a certain amount of an emulsifier and an organic solvent. The emulsifiable oil has strong permeability and good dispersibility, and is diluted with water to become an emulsion. Its application methods are:
1. Spray method. The cream is diluted with water to make the desired concentration, and sprayed evenly onto the crop or other control objects with a sprayer. The amount of application is such that the leaf surface is sufficiently wet and the liquid does not flow from the blade.
2. Soaking method. Dilute the emulsifiable concentrate with water to a certain concentration to soak the seeds. When soaking seeds, place the seeds in a coarse cloth bag or gauze bag, pre-dip in clear water, then drain the water and immerse it in the prepared liquid. When soaking seeds, pay attention to mastering the soaking concentration, soaking temperature and soaking time.
3. Seed dressing method. The agent is evenly mixed with the seed to kill germs and pests on the seed. When mixing the seeds, mix them while spraying. After spraying, continue to flip until the seeds are all wet. Then cover the film for a few hours before planting.
