摘要
2009年7月中旬至2010年9月,从贵州5个辣椒主产区采集到疑似辣椒炭疽病标样,根据病原菌的形态特征和致病性测定,初步确定了贵州辣椒炭疽病包括黑色、黑点和红色炭疽病,且以黑色炭疽病发生最为严重,并对其病原菌进行了室内毒力测定,结果表明:70%甲基托布津具有较好的防治效果,EC50为120.58μg/mL,其他供试药剂效果较差。
Samples of anthracnose were collected from stands of diseased pepper from July in 2009 to September in 2010 in Guizhou five plantation.According to its symptom characteristics,pathogenicity,characteristics of morphology,color of the colonies,morphology of conidium,the results of morphologic observation all showed that the pathogen was identified as C.nigrum Ell.;V.capsici Syd.;G.piperatum Ell.C.nigrum was main pathogenic bacteria,and indoor toxicity determination.The result showed that 70% thiophanate-methyl had the better control efficiency,EC50 was 120.58 μg/mL,and the others were weak.
