| dc.description.abstract | Varietal screening and effect of seed treatment on the incidence of sorghum shoot fly (Atherigona soccata Rondani) Chandra Bhan* Dr. Hemant Swami The investigation on, “Varietal screening and effect of seed treatment on the incidence of sorghum shoot fly (Atherigona soccata Rondani)” was carried out at the Instructional Farm, Rajasthan College of Agriculture, Udaipur during Kharif, 2017. The populations of shoot fly (Atherigona soccata Rondani) were recorded in significant numbers on sorghum crop during the growing season. The investigation revealed that the incidence of shoot fly commenced in the fourth week of July. The mean plant vigour and leaf glossiness were significantly negatively correlated with dead heart formation. The insect pest infestation significantly influenced the attributing characters and sorghum grain yield. The insect pest infestation caused reduction in mean plant vigour of 2.67 and in mean leaf glossiness of 3.00 in varietal screening. Similarly pest infestation caused reduction in mean height of plant of 14.04 cm, in mean plant vigour of 1.25, in mean number of plant stand of 10.84 and in mean grain yield per plot equivalent to a loss of 7.13 q/ha in seed treatment. Among the eight sorghum varieties evaluated against shoot fly, the variety CSV-23 was observed to be significantly better than the susceptible variety with a minimum mean per cent oviposition (53.35) at 12 DAG. the variety CSV-23 and CSV-20 exhibited minimum average percentage dead hearts (11.22 and 11.76) on the 14th day after germination. Similarly, the variety CSV-23(16.77) and CSV-20 (16.82) resulted in minimum average percentage dead hearts on the 21st day after germination. The variety CSV-23 with 20.82 per cent dead heart was significantly superior over the susceptible variety CSV-10 on 28th day after germination. Among the nine treatments the seed treatment by imidacloprid 70 WS was better than the all treatments and control with a minimum mean per cent oviposition (43.31) at 12 DAG. the seed treatment with imidacloprid 70 WS was observed to be significantly better than the all treatments on the 14th, 21st and 28th day after germination with a mean dead heart formation of 11.74, 18.04 and 22.14 per cent respectively.
