Abstract:
An experiment entitled “Impact of Abiotic factors on the Incidence of Sorghum shoot fly Atherigona soccata.” was conducted at the Sorghum Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist: Ahmednagar (Maharashtra) during rabi 2021-22. During the course of study, sowing was done on 17th October 2021 for screening of different genotypes of sorghum against shoot fly, whereas for studying the effect of sowing dates on incidence of sorghum shoot fly on six dates at 15 days intervals starting 1st from 31st August 2021.Data on weather parameters were collected to correlate the influence of the abiotic factors with incidence of sorghum shoot fly. The results showed that most of the important rabi sorghum crops suffered heavily from the incidence of major insect pests resulting into reductions in their yields, when sowings were delayed. Correlation study indicated that rainfall in positively correlated with shoot fly infestation whereas maximum temperature negatively correlated with shoot fly infestation.
