Problems solved by technology

However, since CYP51 also affects the synthesis of gibberellin at the same time, it will inhibit the synthesis of gibberellin in plants and inhibit its growth, especially for dicotyledonous plants.
At the same time, there are many types of SBIs fungicides, and their action principle sites are the same, so there are occasional obvious cross-resistance between these types of fungicides

Abstract

The invention relates to a composition containing picarbutrazox and a sterol-biosynthesis-inhibitor (SBIs) bactericide and a preparation thereof and applications of the composition and the preparation. The bactericidal composition comprises a bactericidal activity compound I and a bactericidal activity compound II, the bactericidal activity compound I is the picarbutrazox, and the bactericidal activity compound II is the sterol-biosynthesis-inhibitor (SBIs) bactericide. The bactericide composition has the advantages of being wide in control spectrum and free of cross resistance, the using quantity and the using number of the picarbutrazox and the sterol-biosynthesis-inhibitor (SBIs) bactericide can be obviously decreased, and the resistance is delayed. The invention also provides the preparation of the bactericidal composition, a preparation method suitable for the composition is designed, the effect of a medicament can be developed to a maximum degree, and the using quantity of the medicament is decreased. The invention also provides the applications of the bactericidal composition and the preparation, so that medicine is guided to be correctly used, and misusing of the medicament is reduced.

Description

Technical field [0001] The invention belongs to the field of agriculture, and relates to a bactericidal active compound composition, in particular to a composition containing picarbutrazox and a sterol biosynthesis inhibitor bactericide, and preparations and applications thereof. Background technique [0002] In the production of crops, fungal diseases occur frequently, with heavy losses and difficult control. With the prolonged use of the existing single agent, the resistance and drug resistance of the bacteria to the agent has increasingly become a major problem for plant protection personnel. However, the development cycle of new active substances is long, the cost is high, and the difficulties are great, and they are far from meeting the needs of agricultural production. The correct combination of medicaments can not only expand the control spectrum, produce synergy, reduce the dosage of medicaments, reduce the cost of prevention and control, but also delay the development o...
