Incidence of the Pink Noctuid Stem Borer, Sesamia inferens (Walker), on Wheat under Two Tillage Conditions and Three Sowing Dates in North-western Plains of India
Beant Singh

The pink stem borer, Sesamia inferens (Walker) (Lepidoptera: Noctuidae) is emerging as an important pest of wheat in India due to change in tillage system. It causes severe damage by forming “dead hearts” at seedling stage and “white ears” at ear-head stage. Studies were undertaken to know the effect of different tillage conditions and date of sowing on the incidence and damage caused by pink stem borer. The experiment was configurated in split block design with tillage conditions as main plot treatment and dates of sowing as sub plot treatment. Both tillage conditions and dates of sowing have significant effect on the incidence and damage caused of pink stem borer. However, effect of tillage conditions on yield was non-significant. Interaction of tillage conditions and dates of sowing indicated that there was no significant difference between two tillage conditions for pink stem borer incidence in the timely sown crop but it was higher in zero tillage if the crop was sown earlier or later than the recommended time period.

it is a nice paper mainly based on agronomic practice to help in pest reduction.
