Fifty four seed samples of three cucurbits namely sweet gourd (Cucurbita moschata Duch. Ex Poir.), white gourd (Benincasa
hispida Cogn.) andbitter gourd (Momordica charantia L.) werecollected from sixdifferent districts of Bangladesh, to find out
asuitabledetectiontechniqueofassociatedseed-bornefungiinlaboratoryconditions. Threedifferentdetectionmethodsnamely,
dry inspection, blotter test and seedling symptom test were compared in present study. Among the tested three detection
techniques, moreinfection rateswereobserved forAspergillus flavus andPenicillium inallcucurbitseedsinblottertest method,
whereas higher infection caused by Fusarium and Rhizopus were recorded in test tube seedling symptom test. The higher
germination percentage of cucurbit seedswas observed inblotter testand itis lessexpensive, quick anduseful for the detection
of most of the infectious fungi.
