Abstract:

The paper aims to clarify the effects of Bordeaux mixture on the downy mildew and white rot of grape, with Cabernet Sauvignon of 22 and 6 years and table grapes as test materials. The results showed that: the dynamic changes of efficacy of Bordeaux mixture on grape diseases in different periods were related not only to the climatic factors at that time, but also the cultivation management; as to the comprehensive effect, the effects of Bordeaux mixture on controlling the downy mildew and white rot of grape were different in different periods (from early June to mid-October), but the dynamic trend of efficacy was the same; the efficacy against downy mildew and white rot was the highest from early June to mid-June, and the lowest from mid-August to late September.
