SCREENING OF VARIOUS INERT DUSTS AND MATERIALS OF PLANT AND ANIMAL DERIVATIVES FOR THEIR EFFECTIVENESS IN REDUCING STORAGE LOSSES IN COWPEAS

Of twenty inert materials tested, eight gave protection to cowpea seeds in storage, from the cowpea weevil Ca1losobruchus ch i nensis (L) foe up to three months. Red mud, black pepper and paddy husk ash prevented infestation even at a low dosage of 6,7g dust/kg seed. Dosages of 13.4g dust/kg seed and 19.lg dust/kg seed also gave complete protection. Pork fat and coconut oil prevented infestation at 4.2m] oil/kg seed, but failed to do so at dosages of 1,4ml oil/kg seed and 2.8ml oil/kg seed.
