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 fungicidal active compound composition, in particular to a composition containing 2-mercaptobenzothiazole zinc and sterol demethylation inhibitors (DMIs) fungicides, as well as its preparation and application. Background technique [0002] In crop production, bacterial diseases and fungal diseases often occur in combination, resulting in heavy losses and difficult control. Existing single agents often cannot meet the requirements of preventing and controlling multiple diseases at the same time, and with the prolongation of use time, the resistance and resistance of pathogens to agents has become a major problem for plant protection personnel. However, the development cycle of new active substances is long, the cost is high, and the difficulty is great, which is far from meeting the needs of agricultural production. Combining the correct combination of pesticides can not only expand th...
