Medicament for fast preventing and controlling malignant aquatic weed and algae and uses thereof

Abstract

The invention relates to a medicament for fast preventing the malignant float grasses and the water algae and the application thereof, belonging to the pesticide formulation technical field, which is characterized in that the medicament comprises from 40% to 90% of a plant vinegar fluid, from 5% to 35% of an organic acid, and from 1% to 20% of pesticide addition agent, the plant vinegar fluid is either a bamboo vinegar fluid, a wooden vinegar fluid, and (or) grass vinegar fluid, the organic acid is one of or a mixture of more than one of a formic acid, an acetic acid, a propionic acid, a 2-methyl propionic acid, an ethyl acetic acid, a 4-hydroxy ethyl acetic acid, a pentanoic acid, a benzoic acid, a 2,6-hydroxy benzoic acid, a 3-hydroxy-4-methoxy benzoic acid or a 3-methoxy-4-hydroxy benzoic acid. The medicament has the advantages of fast destroying the chlorophyll, stopping the plant to do the photosynthesis, commonly killing the water algae in a half hour and the float grass in three hours by spraying, having low production cost, strong killing capability, wide adaptable temperature range and pH value range. The active component of the invention has the advantages of being the natural-occurring substance, no corrosion, nonirritant, safe use, and reliability, easy biodegradation, and no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, in particular to a medicament for rapidly preventing and controlling malignant aquatic plants and algae and its application. Background technique [0002] "Water blooms" is a natural ecological phenomenon in fresh water, which is caused by algae such as cyanobacteria, green algae, and diatoms. The phenomenon of "Water Bloom" has been recorded in the ancient history of our country. When "Water Bloom" occurs, the water is generally blue or green. They disappear quickly in nature and do not bring harm to aquatic animals and humans. After eutrophication in fresh water, "water blooms" appear frequently, the area spreads year by year, and the duration is extended year by year. Taihu Lake, Dianchi Lake, Chaohu Lake, and Hongze Lake all have "water blooms", and even flowing rivers, such as the largest tributary of the Yangtze River-the Hankou section of the lower reaches of the Han River,...
