Bio-efficacy of bas 306 02 I 240 SC against major insect pests of chilli during rabi season 2016-17 to 2017-18

An experiment was conducted to observe the “Bio-efficacy of BAS 306 02 I 240 SC against major insect pests of chilli during Rabi Season 2016-17 and 2017-18” at Horticulture farm, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur. During the bio efficacy trial among the insecticidal treatments, T3 @ 240g a.i. /ha BAS 306 02 I 240 SC were showed significantly superior mortality over untreated control in effectively control the major insect pests population of chilli. All the tested doses of insecticides, there was no phytotoxicity symptoms were recorded in chilli crop. Among all the insecticidal treatment minimum coccinellids beetle population was observed in (T4) BAS 306 02 I 240 SC @ 288 g a.i. /ha (0.17 coccinellids beetle per plant), followed by (T3) BAS 306 02 I 240 SC @ 240 g a.i./ha (0.26 coccinellids beetle per plant),(T2) BAS 306 02 I 240 SC @ 192 g a.i. / ha (0.24 coccinellids beetle per plant), and were found statistically at par. There was maximum coccinellids beetle population (0.36 coccinellids beetle per plant) in untreated control (T7). On the basis of pooled data 2016-17 and 2017-18 the highest average yield of 106.11 q/ha was recorded in the T3 plot treated with BAS 306 02 I 240 SC @ 240 g a.i./ha followed by T4-BAS 306 02 I 240 SC @ 288 g a.i./ha (106.11 q/ha) as compared to the control (78.00 q/ha).
