Abstract
The invention relates to a bactericide composition containing oligosaccharide and copper. The composition is characterized by being prepared from main active ingredients such as oligosaccharide and a copper preparation and pesticide auxiliaries and comprising the following components in percentage by weight: 1-45% of oligosaccharide, 1-50% of copper preparation and the balance of pesticide auxiliaries, wherein the oligosaccharide is one of amino-oligosaccharin (chitosan oligosaccharide), oligogalacturonide acid (pectic oligosaccharide, oligosaccharin) and sodium alginate oligosaccharide; the copper preparation is an inorganic copper or organic copper bactericide; and the dosage form of the bactericide composition can be water agents, emulsion in water, wettable powder, water dispersible granules, suspensions, granules, paste or microcapsule sustained-release agents. The composition has the following beneficial effects: the drug resistance of crops is overcome and delayed; the disease resistance of the crops is improved; the composition can generate synergy together with chemical bactericides; and the composition is safe in application and is safe to the environment and people.
Description
technical field [0001] A fungicide composition containing oligosaccharides and copper relates to the compounding of a large part of copper-based pesticides and belongs to the technical field of pesticides. Background technique [0002] At present, chemical pesticides have played a huge role in increasing agricultural production and ensuring income due to their fast, effective and low prices. However, if they are used indiscriminately, they will cause serious problems such as ecological environment pollution and drug residues, and lead to the development of pathogenic bacteria resistance. Continuously enhancing and increasing numbers of pathogenic variants. Therefore, the use of many pesticides has been gradually banned, and there is an urgent need to develop new pollution-free and degradable biopesticides. As a biopesticide, oligosaccharides have the advantages of being harmless to humans and the ecological environment, lasting efficacy, not easy to produce drug resistance,...
