Composition containing resin acid copper salt and captan, preparation method and application thereof

Abstract

The invention discloses a composition containing resin acid copper salt and captan, a preparation method and application thereof, and belongs to the technical field of pesticide. The composition containing resin acid copper salt and captan comprises the following raw materials in parts by weight: 1 to 30 parts of resin acid copper salt, and 1 to 70 parts of captan. The invention further disclosesa preparation method and application of the composition containing resin acid copper salt and captan. The composition is prepared by taking resin acid copper salt and captan as raw materials, and canproduce high synergistic effect, expand bactericidal broad-spectrum, and overcome and delay producing drug resistance by pathogenic bacteria. The composition is superior to a single agent in terms ofcontrol effect, rainwater washing resistant, good in fast-acting property, and long in lasting period, ensures that the number of use is reduced, can control various pathogenic bacteria and diseases at the same time, and reduces the pesticide use cost. The composition particularly has obvious synergistic effect on citrus red mite, citrus rust mite, citrus melanose, citrus anthracnose, citrus downymildew, citrus canker, citrus gray mold and citrus whitefly and aphid, and is good in control effect.

Description

Technical field [0001] The invention relates to a composition containing copper rosinate and captan, a preparation method and application thereof, and belongs to the technical field of pesticides. Background technique [0002] Citrus psyllid is the only vector for the transmission of Huanglong disease. If there are young shoots in the same year, it can occur 11 to 14 generations a year. The field generations overlap. The transmission rate of a single psyllid is as high as 70-80%, and the adult can fly. The prevention and treatment is difficult. At the same time, in various growth stages of citrus, in addition to citrus psyllids, there are also citrus red spiders, citrus rust ticks, citrus leaf miners, citrus whitefly aphids and other insect pests and citrus resin diseases (shader disease). ), citrus anthracnose, citrus downy mildew, citrus gray mold, citrus canker, citrus black rot and other diseases occur at the same time, so there is an urgent need to solve the problem of such...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the unscientific and unreasonable single use and application of pesticides, the resistance of pests to the currently used pesticides is rapidly aggravated, and the service life of some high-cost, long-term investment in the development of new pesticide ingredients is shortened. , but also aggravated environmental pollution and increased the cost of medication

At present, for the prevention and control of diseases that are prone to resistance in agriculture, the main method is to develop new ingredients that have no cross-resistance with existing varieties or compound between existing pesticide varieties. The former requires high development costs and long cycles. , and the current development speed is far behind the speed of pathogenic bacteria resistance
