Abstract
Protomyces macrosporus Unger inciting the stem gall disease of coriander (Coriandrum sativum L.) is perpetuated through the resting chlamydospores released in the soil after the monsoon rains from the crop debris and/or the fruit galls in uncleaned seed lot planted in the season. The pathogen also survives in the soil through the heat-resistant desiccated endo- and blastospores and possibly through the chlamydospores hibernating in an intensively cultivated field.
