Effects of Acute Low-Temperature Events on Development of Erysiphe necator and Susceptibility of Vitis vinifera
Growth and development of Erysiphe necator (syn. Uncinula necator) has been extensively studied under controlled conditions, primarily with a focus on development of grapevine powdery mildew within the optimal temperature range and the lethal effects of high temperatures. However, little is known of...
