Problems solved by technology

The result of excessive use is that long residues cause a large number of large submerged plants such as Elodea in the water body to die, and fish and crab fatal accidents often occur, causing serious economic losses to farmers.
[0006] Other products used to kill algae, such as polythiazium chloride and other quaternary ammonium salts, are widely used in swimming pools, pipeline construction, daily chemicals, etc. to kill algae, but they are harmful to aquatic organisms, especially shrimps and crabs. Crustaceans are highly toxic and cannot be used in ponds, reservoirs and other water sources; peroxides have a good effect on cyanobacteria and are environmentally friendly, but they have low activity and high cost of use, so they can only be used in places that are not sensitive to prices; phthalocyanine copper is An excellent sunscreen, especially suitable for deep water bodies, but for shallow water bodies, or environments where algae have expanded in large areas, the effect is relatively poor, and the application scenarios are more limited. Therefore, it is necessary to develop a sunscreen that can be used in natural water bodies. , bonsai, aquatic production and other places, and can control the excessive reproduction of algae, and at the same time, it is very necessary for products with good water environment compatibility

Abstract

The invention discloses an algae control composition which comprises water-soluble copper and a complex thereof and a herbicide, and the weight ratio of the content of copper in the water-soluble copper and the complex thereof to the herbicide is (0-99): (99-0). The water-soluble copper and the complex thereof are matched with the herbicide for use, compared with the dosage of a single agent, after 1/3 of the dosage of a single component is mixed in a mixed agent, the generated synergistic effect is superior to the 100% prevention effect of the single agent, the synergistic effect is achieved, meanwhile, the fast-acting property and the lasting period are well balanced, the prevention and control cost is greatly reduced, and the prevention and control effect is better. And the use cost is only 40-60% of the cost of a single agent.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an algae control composition used in places such as rivers and lakes, paddy fields, ponds, reservoirs, rivers, garden landscapes, fish tanks, fish ponds, latex and coatings. Background technique [0002] In recent years, with the intensification of water eutrophication, the frequency of cyanobacterial blooms has gradually increased in China and even around the world. The outbreak of cyanobacteria and other blooms has led to the outbreak of algal blooms in ponds and rivers, odors in ponds, and dead fish and shrimp. , especially in Taihu Lake and other places, the pressure of prevention and control is relatively high every year, and the environmental protection department is also taking measures such as renovation of water conservancy facilities, control of water entering the lake, and planting of reeds and water plants along the lake to control algae and prevent them...
