Neem oil prepn for preventing and controlling algae and its prepn process

Abstract

The neem oil preparation for preventing and controlling algae contains neem oil 1-49 wt%, water 50-98 wt%, Tween-60 or Tween-80 0.1-5 wt%, Span-60 or Span-80 0.05-5 wt% and nimbin 0.001-5 wt%. The water emulsion prepared with neem oil and through emulsification is safe and degradable and has no secondary pollution to water. It is used for direct killing and inhibition of algae in dramatic growth in summer, and before being used, it is diluted into the concentration of 0.4-20 ppm.

Description

technical field [0001] The invention relates to preparation of water algae prevention and control preparation and its preparation method with printing oil. Background technique [0002] The eutrophication of water causes the uncontrolled growth of algae, making the water turbid and smelly. How to suppress the uncontrolled growth of algae has become a difficult problem for the world to overcome: 1. Chemical method: direct injection of medicines to kill algae, the killing effect is good, but it will cause secondary pollution to the water body; 2. Explosion method: through the relevant equipment to The treatment of water body reduces the degree of eutrophication of water and inhibits the growth of algae. This method is difficult when dealing with large areas of water; 4. Ecological wetland method: This method uses the ecological wetland itself to treat the eutrophic water body to inhibit the growth of algae. Small capacity and slow speed. [0003] Existing prednisolone or pr...
