| Summary: | A study of in vitro sensitivity of five Alternaria solani isolates to cooper-oxychloride,
chlorothalonil, difenoconazole, pyraclostrobin and a biofungicide based on tea tree
essential oil was carried out. The isolates were obtained from infected tomato leaves
collected from five different locations in Serbia. The tested isolates showed the highest
sensitivity to pyraclostrobin with EC50 values ranging from 0.0014 to 0.0041 μg ml-1. The
EC50 values of difenoconazole were 0.018-0.037 μg ml-1, chlorothalonil 2.99-4.54 μg ml-1, and
cooper-oxychloride 13.27-15.63 μg ml-1. All tested A. solani isolates were the least sensitive
to tea tree oil (1323.97-3307.08 μg l-1). |
