Abstract

The invention relates to compositions containing bactericidal-activity compounds, and especially relates to a composition containing zinc 2-mercaptobenzothiazole and sterol demethylation inhibitors (DMIs) bactericide, and a preparation and application thereof. The composition contains a bactericidal-activity compound I and a bactericidal-activity compound II, the bactericidal-activity compound I is zinc 2-mercaptobenzothiazole, and the bactericidal-activity compound II is at least one selected from difenoconazole, diniconazole, epoxiconazole, fenbuconazole, flusilazole, flutriafol, tebuconazole, hexaconazole, myclobutanil, penconazole, propiconazole, tetraconazole, triadimenol, bitertanol, triadimefon, prothioconazole, tricyclazole, imazalil, prochloraz and triflumizole in sterol demethylation inhibitors. The sterilization composition fills bactericidal spectrum blanks of the two kinds of agents, the bactericidal spectrum is enlarged, and the farm work strength 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 zinc 2-mercaptobenzothiazole and a sterol demethylation inhibitor (DMIs) bactericide, and preparations and applications thereof. Background technique [0002] In crop production, there are many mixed occurrences of bacterial diseases and fungal diseases, causing heavy losses and difficult control. Existing single agents often cannot meet the requirements for the simultaneous prevention and control of multiple diseases, and with the prolonged use of time, the resistance and drug resistance of pathogens to agents 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...
