Determination on Sensitivity of Botryosphaeria berengriana to Mancozeb in Shandong Province
摘要
Abstract
The Mancozeb - sensitivities of 54 strains of Botryosphaeria berengriana f. Sp. Piricola isolated from the diseased apple fruits in Shandong from August to October in 2007 were determined with the method of mycelial growth rate. The frequency distribution of Ecjq value of Mancozeb to these 54 strains was unimodal, the EC^ values ranged from 1. 9287 u>g/mL to 20. 8004 jjLg/mL, and the mean Ecjovalue was (9.4383 ±0.5561) |xg/mL. The sensitive baseline of Botryosphaeria berengriana f. Sp. Piricola to Mancozeb was determined as 3. 0963 u,g/mL based on the mean EC50 value of Mancozeb to the most sensitive strain isolated from Taishan. The results of Duncan' s test and hierarchical clustering analysis showed that the sensitivities of Botryosphaeria berengriana f. Sp. Piricola from different regions to Mancozeb were at high levels. There was generally no evident difference in the sensitivity among different strains, and the resistant sub - colony was not found.关键词
