Problems solved by technology

[0003] There are many kinds of filamentous algae, and the traditional prevention and control technology mainly relies on physical and chemical methods for prevention and control. The physical method is manual or mechanical salvage, which has the problems of limited operation by environmental conditions, poor control effect and high cost of manpower and equipment; Chemical methods use various agricultural herbicides, water treatment biocides and heavy metal salts and other chemical agents. Although the control effect is better, excessive use will easily cause environmental pollution and ecological risks.
Therefore, existing technical means all can't reach the prevention and treatment to harmful filamentous baths.

Abstract

The invention provides a spray additive for improving the removal effect of harmful filamentous algae in farmland or water body. The spray additive is composed of the following components: plant-derived allelochemicals, an emulsifier, a wetting agent, mineral oil or modified vegetable oil, a solvent and a preservative. The spray additive is applicable to manual application, conventional mechanical spraying, ultra-low volume spraying and aviation plant protection spraying, all the selected raw materials exist in natural plants or can be rapidly degraded and converted into harmless substances in the natural environment, the spray additive has the advantages of being natural and free of pollution, pesticide residues and environmental pollution are not generated, and the spray additive can generate a serious threat to aquatic organisms, has a good application prospect in the aspect of auxiliary prevention and treatment of harmful filamentous algae in the farmland or water body.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to a spray adjuvant for improving the removal effect of harmful filamentous algae in farmland or water bodies. Background technique [0002] At present, due to the increasing eutrophication of farmland and water bodies due to the intervention of human activities, the number of algae organisms in water bodies is increasing, and the dominant species among them are very easy to form algal blooms, which are very harmful. The massive growth and reproduction of filamentous algae will cause serious harm to water bodies and aquatic organisms (including: artificial wetlands, landscape water bodies, shrimp and crab fields, fish ponds, rice fields, irrigation canals, etc.), such as water hypoxia, algae toxin accumulation, reduction Water temperature, destroying the balance of biodiversity, obstructing waterways, affecting production, etc. [0003] There are many kinds of filamento...
