Management of Sesame Phyllody: A Destructive Disease of East- Central Rajasthan, India

Abstract

Sesame (Sesamum indicum L.) is one of the important annual oldest oil seed crop grown in tropical to temperate zones in India. It belongs to family Pedaliaceae is native of India and plays an important role in the oilseed economy throughout the world. The sesame crop suffers from phyllody disease caused by phytoplasma. The effect of different treatments on “percent” disease incidence. The results obtained revealed that all the treatments reduced the disease significantly compared to unsprayed control. Seed treatment with imidachlorprid 70 % WG + spraying of imidachlorprid 17.8% SL+ spraying of tetracycline hydrochloride recorded the least disease incidence (7.27 %), minimum leaf hopper population and maximum “percent” disease control (65.59 %) and while seed treatment with imidachlorprid 70 % WG was least effective in which disease incidence of 15.46  “percent” and maximum leaf hopper population was recorded. The disease incidence in untreated check was 21.13 “percent” was recorded. Out of 22 germplasms/varieties screened against sesame phyllody 1 genotype was susceptible, 10 were moderately susceptible, 7 were moderately resistant and 4 genotypes were found resistant against phyllody of sesame.
