Description Investigations on the screening of germplasm against pest complex and
management of S. litura were undertaken during rabi, 2004-2005 at the Agricultural
College Farm, Bapatla.
A total of 34 genotypes was screened for resistance against pest complex in
comparison with two standard checks viz., JL 24 and TMV-2. The variety, TMV-2
was used in the management trial. Among the 34 genotypes screened against the pest
complex,
ICGV – 86031, ICGV – 86590, K – 1320, K – 1340 and K – 1383 were found
resistant against the aphid, Aphis craccivora Koch; ICGV – 86031, ICGV – 86252,
ICGV-86393,
ICGV – 86590, K – 1268, K – 1274, K-1310, K - 1327 and K – 1340 were found
resistant against the leafhopper, Empoasca kerri (Pruthi); ICGV – 86031, ICGV –
86252, K – 1320, K – 1340, K – 1363 and K – 1383 were found resistant against
the leafminer, Aproaerema modicella (Deventer). The genotypes, ICGV –
86031 and K – 1340 were found resistant against all the three pests.
Investigation on the management of S. litura on groundnut revealed treatment
with indoxacarb (0.0145%) alone, combination treatments of novaluron (0.005%)
with indoxacarb (0.00725%) and spinosad (0.0075%) to be the most effective in
reducing the larval populations of S. litura followed by the corresponding individual
treatments. The treatments, novaluron (0.005%) + B. t. (0.1%), novaluron (0.005%) +
nimbecidine (0.15%) and poison bait I were the least effective among all the
treatments against S. litura.
The treatments, indoxacarb (0.0145%) alone, novaluron (0.005%) + spinosad
(0.0075%) and novaluron (0.005%) + indoxacarb (0.00725%) recorded the highest
pod yields whereas, novaluron (0.005%) + B. t. (0.1%), novaluron (0.005%) +
nimbecidine (0.15%) recorded the lowest pod yields.
