Yield enhancement in mango crop with effective management of leaf hoppers and powdery mildew

Abstract

A Front line demonstration was conducted on Management of leaf hoppers and powdery mildew in Mango crop at farmers fields of Nagarkurnool district, Telangana during the year 2016-17 to 2017-18. The main objective of front line demonstrations (FLDs) was to demonstrate study the efficacy of plant protection aspects for getting the higher yields. The demonstration comprised of two treatments viz., T1-Farmers practice (Sprayed Acephate 75% SP 1.5 gm/lt, Profenophos 50% EC 2ml/lt.of water) and T2-Demonstartion (Sprayed Thiomethoxam 25% WG 0.3 gm/l + Wettable Sulphur 90% WDG 3g/l at flower initiation stage and Imidacloprid 17.8% SL 0.3 ml + Hexaconazole 5% EC 2 ml/ lt at bud formation to marble fruit stage).The results showed that drastically reduced the average incidence leaf hoppers and powdery mildew. In demo only 10.50% and in farmers practice 22.50% of incidence of leaf hoppers and powdery mildew was observed. The cumulative effects of technological intervention over two years, revealed that mean average fruit yield was 108.92 q/ha under demo and 94.27 q/ha in compared to farmers practice. Net returns and B: C ratios were found to increase in demonstrated plots over farmers practice.
