Effect of some newer insecticides on damage intensity of Chilo partellus in Kharif maize


Author(s): Ram Kumar and Tanweer Alam

Abstract: The present experiment was carried out to assess the effectiveness of various insecticides against maize stem borer, Chilo partellus at research farm, Tirhut College of Agriculture, Dholi, Muzaffarpur (Bihar) during Kharif 2016 under field condition. The application of chlorantraniliprole 20 SC @ 0.3 ml/l as spray followed by carbofuran 3G @ 7 kg/ha as whorl application at fortnightly interval starting from 15 days after sowing recorded highest plant height, number of cobs per plant and grain yield but did not differ statistically from flubendiamide 480 SC @ 0.2 ml/l followed by carbofuran 3G @ 7 kg/ha. Maximum plant height (175.0 cm), mean number of cobs per plant (1.50) and mean grain yield (45.4 q/ha) was recorded in maize with spraying of chlorantraniliprole 20 SC @ 0.3 ml/l followed by application of carbofuran 3G @ 7 kg/ha which might be due to effective reduction of pest attack. Among all the insecticides, novaluron 10 EC @ 0.1 ml/l was least effective but was significantly superior over untreated control in respect of all the above mentioned parameters.
