CSA Xpert

Seed and un-emerged seedlings attacked by the pathogen are rapidly shriveled and dried.Brown or black mass covered by yellow or greenish spores may be seen. Decay is most rapid when infected seeds are planted. After seedling emergence cotyledons already infected with the pathogen, show necrotic lesions with reddish brown margins. This necrosis terminates at or near the cotyledonary axis. Under field conditions the diseased plants are stunted, and are oftenchlorotic. The leaflets are reduced in size with pointed tips, widely varied in shape and sometimes with veinal clearing.
