Le résumé fourni par la source

Pooled data revealed that chlorantraniliprole 18.5% w/w SC @ 30 g a.i./ha was found most effective treatment which showed 70.12–89.47% reduction in larval population over untreated control during fortnight interval with 0.20–0.56 average larvae/plant and 68.25–71.46% reduction in damaged plants over untreated control due to larval infestation with 13.18–14.49% actual damaged plant in treatment plots. It also recorded the highest of 83.86 q/ha grain yield as against 61.61 q/ha in an untreated control. Flubendiamide 90 g/l + deltamethrin 60 SC @ 36+24 g a.i./ha was the second next best treatment in which 67.55–84.46% reduction in larval population with average 0.29–0.58 larvae/plant and 66.53–70.16% reduction in damaged plants with 13.49–15.14% actual damaged plants. 82.92 q/ha grain yield was recorded in this treatment. Flubendiamide 90 g/l + deltamethrin 60 SC @ 31.5+21 g a.i./ha was the third next best treatment with 63.85–83.12% reduction in larvae and 59.44–64.39% reduction in damaged plants with 81.64 q/ha grain yield. Foliar application of evaluated treatments was found safe to natural enemies of fall armyworm.
