Missible oil containing resin acid copper salt and pyraclostrobin, preparation method and application thereof

Abstract

The invention discloses missible oil containing resin acid copper salt and pyraclostrobin, a preparation method and application thereof, and belongs to the technical field of pesticide. The missible oil containing resin acid copper salt and pyraclostrobin comprises the following raw materials in parts by weight: 1 to 30 parts of resin acid copper salt, and 1 to 40 parts of pyraclostrobin. The invention further discloses a preparation method and application of the missible oil containing resin acid copper salt and pyraclostrobin. The missible oil is prepared by taking resin acid copper salt andpyraclostrobin as raw materials, and can produce high synergistic effect, expand bactericidal broad-spectrum, and overcome and delay producing drug resistance by pathogenic bacteria. The missible oilis superior to a single agent in terms of control effect, rainwater washing resistant, good in fast-acting property, and long in lasting period, ensures that the number of use is reduced, can controlvarious pathogenic bacteria and diseases at the same time, and reduces the pesticide use cost. The missible oil has an obvious synergistic effect on citrus red mite, citrus rust mite, citrus melanose, citrus anthracnose, citrus downy mildew, citrus canker, citrus gray mold and citrus whitefly and aphid, and is good in control effect.

Description

technical field [0001] The invention relates to an emulsifiable concentrate containing copper rosinate and pyraclostrobin, a preparation method and application thereof, belonging to the technical field of pesticides. Background technique [0002] The citrus psyllid is the only medium for the transmission of Huanglongbing. If there are young shoots in the same year, there can be 11 to 14 generations in a year. The generations overlap in the field. The disease transmission rate of a single psyllid is as high as 70-80%. Adults can fly. Prevention is difficult. At the same time, in each growth period of citrus, in addition to citrus psyllid, there are also insect pests such as citrus red spider, citrus rust tick, citrus leaf miner, citrus whitefly aphid and citrus resinous disease (sand skin disease). ), citrus anthracnose, citrus downy mildew, citrus botrytis, citrus canker, citrus black rot and other diseases occur simultaneously, so it is urgent to solve such pest problems. ...

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
