Effect of Environmental-Friendly Control for White Stain Symptom on Grape

BACKGROUND: White stain symptom caused by Acremonium acutatum and Trichothecium roseum, is one of the most important diseases on the grape. This disease occurs national-wide in Korea and causes irreversible damage on grape, at harvest season. This study was conducted to develop environment-friendly control method against white stain symptom. METHODS AND RESULTS: Environment-friendly materials were tested for control activity against A. acutatum and T. roseum in vitro and in vivo. The effect of environment-friendly materials against white stain symptom on grape in farmer's greenhouse was examined. The materials, NaDCC and sulphur, were sprayed three times on the leaves and fruit of grape at the two sites of farmer's field, Anseong and Hwaseong of Gyeounggi. To evaluate control effect of NaDCC and sulphur against white stain symptom, the disease severity was investigated after the two materials were sprayed from the disease onset three times at the 7-day intervals. NaDCC showed efficacy of 59.71% for Kyoho and 72.26% for Campbell-Early, and sulphur showed 78.31% for Koyho and 66.19% for Campbell-Early. CONCLUSION: We were selected sulphur and Sodium-Dichloroisocyannurate(NaDCC) based on the results of experiments in vitro. In field test, sulphur and NaDCC showed suppressive effect in the white stain symptom of grape. These results suggested that NaDCC and sulphur selected can be used as control agents for controlling white stain symptom on grape.
