Fludioxonil effectively controls Sclerotinia sclerotiorum incited decay in stored carrots in Israel

December 2022

Carrot is an important crop in Israel, subjected to postharvest decay, incited in cold storage by the fungus Sclerotinia sclerotiorum, which may cause up to 7% loss. The fungicide iprodione, which had been used until recently to limit decay was phased-out in 2020. Hence, in the present study, the fungicide fludioxonil was examined as a replacement. In two cold storage trials with artificial inoculations, fludioxonil...

Determination of appropriate packaging materials for cowpea seed storage

June 2019

Quality seed is an important resource for any seed-propagated crop. Cowpea (Vigna unguiculata) seed is prone to cowpea weevil (Callosobruchus maculatus) infestation during storage. This can result in 100% seed loss when stored without treatment. Smallholder farmers in Kenya use traditional methods of storage and occasionally accompanied by pesticides treatment. Due to health concerns, pesticide use is discouraged....
