Field evaluation of two additives for improving the acceptance of some molluscicide baits by the slug, Filicaulis alte Ferussac in vegetable fields at Malerkotla (Punjab)

摘要

For improving the acceptance of poison baits containing 10% carbaryl and 10% nuvan (acting as molluscicide) to control the slug, Filicaulis alte Ferussac mango flavor and apple juice were tested under vegetable field conditions. Three per cent mango flavor and three percent apple juice used to amend 10% carbaryl and 10% nuvan baits in wheat bran, improved significantly the take of and effectiveness of 10% carbaryl (50% WDP) and 10% nuvan (76% EC) in separate field tests. Three percent mango flavor induced, mean percent improvement in 10% carbaryl bait take was 25 and slug mortality 33 in tomato crop while that of 10% nuvan bait take was 19 and slug mortality was 53 in capsicum crop. However, three percent apple juice induced mean percent improvement in 10% carbaryl bait take was 58 and slug mortality 47 while that of 10% nuvan bait take was 62 and slug mortality was 38 in cabbage crop. These flavors might have acted as an attractant in the bait material to attract a large number of slugs, thus increasing toxic bait consumption and slug mortality.
