Abstract:
Chilli (Capsicum annuum L.) is an important commercial crop in India, valued for its enticing colour, taste and pungency. Powdery mildew of chilli incited by Leveillula taurica, is one of the major devastating diseases causing both qualitative and quantitative yield loss. For initiation and progress of the disease temperature and relative humidity plays a key role. Different set of temperature and relative humidity were evaluated under laboratory condition. Results indicated that, the optimum temperature and relative humidity for conidial germination of L. taurica was found to be around 25 ℃ and 85 %, respectively.
