MANAGEMENT OF RED PUMPKIN BEETLE, RAPHIDOPALPA FOVEICOLLIS LUCAS AND SERPENTINE LEAF MINER, URIOMYZA TRIFOLU BURGESS ON CUCUMBER UNDER MID HILL CONDITIONS OF HIMACHAL PRADESH

摘要

Investigations were carried out for three consecutive years (2006-2008) at Seed Technology and Production Centre of Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan. The study revealed that minimum number of red pumpkin beetles (1.64 adults/plant) and minimum leaf infestation (14.57%) caused by serpentine leaf miner were recorded with soil application of carbofuran @ 500 g a.i./ha at the time of sowing followed by seed treated with thiamethoxam 70WS @ 3g/kg seed and dusting with rice husk ash @ 30 kg/ha. Maximum number of fruits (16.53 fruits/plant), fruit weight (7.19 kg/plant), fruits yield (106.13 q/ha) and benefit: cost ratio (1.75) were also recorded in carbofuran.
