Abstract

The present investigation aims to examine the effectiveness of a few recently introduced systemic insecticide as seed dressers and their combined effect against the sorghum shoot fly. A field study carried out in three replications using a Randomized Block Design at the College of Agriculture's Sorghum Research Field in Indore, Madhya Pradesh, during the 2019–20 Kharif season. The sorghum variety CSV 15 was examined for Atherigona soccata oviposition, yield, and germination using six seed dressing chemicals, soil treatment of carbofuran 3G, and an untreated control. The highest germination rate (94.93%), maximum grain yield (23.67q-ha-1), and most avoidable loss (64.93%) were observed by the seed treatment with Thiamethoxam + Cyantraniliprole. Seed treated with Thiamethoxam 30 FS, Fipronil 5 SC and Chlorantraniliprole 18.5 SC also recorded better germination and yield compare to control. The oviposition of shoot fly recorded (5.74 egg/plant) highest in treatment Thiamethoxam + Cyantraniliprole and lowest (3.77) in soil application of Carbofuran 3G as compare to control due to pytotonic effect. Due to variation in the agro climatic conditions of different regions, insects show varying trends in their incidence pattern and extent of damage to the crop. Chemical control solely shows costly and it requires continual applications against target pest. Therefore, the seed treatment seems to be a plausible option for pest management. Thus, it is concluded that for the management of shoot fly seed treatment with (T5) thiamethoxam (19.8 w/w) + cyantraniliprole (19.8 w/w) 6 ml/kg followed by thiamethoxam 30 FS 10 ml/kg (T4) can be recommended on sorghum.

Conclusion

The seed treated with thiamethoxam (19.8 w/w) + cyantraniliprole (19.8 w/w) 6 ml/kg of seed increased germination percent and grain production, according to the results of the field investigations. Thiamethoxam 30 FS 10 ml/kg was the next treatment to achieve these same results. The shoot fly's mean preference for oviposition revealed that the ready-mix combination of Thiamethoxam (19.8 w/w) + Cyantraniliprole (19.8 w/w) 6 ml/kg found maximum number of eggs, followed by seed treated with Thiamethoxam 30 FS 10 ml/kg. The phytotonic impact caused the lowest number of eggs to be detected in untreated plots. Consequently, it can be said that (T5) Thiamethoxam (19.8 w/w) + Cyantraniliprole (19.8 w/w) 6 ml/kg demonstrated the most successful control of shoot fly seed treatment, which is justified because it is a novel combination that has not been evaluated before.
