Peanut pod rot is one of the most important soil-borne diseases on peanut. It will cause pod rot, and the seriously affected field can lead to total crop failure. In recent years, Pythium myriotylum was identified as the main pathogen of peanut pod rot in the major peanut producing areas of China. In order to control this disease efficiently, 6 fungicides were screened indoors, the experimental results showed that 96.8% fludioxonil had best inhibitory effect on mycelial growth of P. myriotylum. The EC50 value was 3.16 x 10-5 mg/L. The six fungicides were used for root irrigation, after potted seedlings inoculation, and the disease incidence was investigated after the pods ripened. The results showed that 96.8% fludioxonil was the best potential chemical agent for preventing peanut pod rot. [ABSTRACT FROM AUTHOR] |
