Abstract

The invention discloses a bactericidal composition containing dichlorooxazole and ametoctradin. The bactericidal composition has an obvious synergistic effect on a plurality of types of crop diseases in a range from (1 to 30) to (30 to 1). The pesticide composition disclosed by the invention is especially suitable for prevention and treatment of potato late blight and cucumber downy mildew; the use amount of active components of pesticides can be reduced, the pesticide cost is reduced, and the prevention and treatment effects are improved; and the pesticide composition disclosed by the invention is safe to crops and is worthy of being popularized and applied in production.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and specifically relates to a pesticide composition containing dicloconazole and pyraclostrobin and its application for blight and downy mildew. Background technique [0002] Potato late blight is a devastating disease in potato production. It occurs widely all over the world. It generally causes a 20-80% reduction in potato production, and severe cases may result in a complete failure. In the 1980s, late blight began to occur frequently all over the world. After the 1990s, late blight commonly occurred in the main potato producing areas of my country, and the damage was on the rise. The huge loss caused by potato late blight has aroused great concern from the international community. The International Potato Center listed potato late blight as a priority research target of CIP in 1992, and established the International Potato Blight Research Collaborative Network in 1996, in order ...
