| Abstract: | A simple in-vitro ‘wet-plate’ method for mass-producing Phytophthora nicotianae zoospores at ≥ 1.0 × 106 zoospores/ml is described. Temperature critically affected zoospore production; 22 °C was optimum, while 36 °C was completely inhibitory. Zoospores being the most important propagule of P. nicotianae, temperature of recycled irrigation water may be manipulated to reduce diseases in irrigated nursery crops. |
