Efficacy of Seed Treatment, Seedling Dip and Foliar Sprays for the Management of Fruit Rots of Brinjal (Solanum melongena)

摘要

Systemic and non systemic fungicides were used as seed treatment, seedling dip and foliar sprays alone and in combination to control fruit rot of brinjal (Solanum melongena) caused by a fungal complex - involving species of Alternaria, Fusarium, Colletotrichum, Phytophthora and Phomopsis. The experiments were conducted at experimental farm of CSKHPKV, Palampur and at farmer's field at Kangra. The systemic fungicide Bavistin (carbendazim 50WP) @ 0.25%) as seed treatment and seedling dip, followed by spray of non-systemic fungicides viz., Indofil M45 (mancozeb), Ridomil MZ (metalaxyl 8%+ mancozeb 64%) and Polyram (metiram 70%) each @ 0.25%) gave 62.4, 62.0 and 56.7% disease control, respectively. Integration of seed treatment, seedling dip with Captan and foliar spray of mancozeb, Ridomil MZ and seedling dip with Captan and foliar sprays with mancozeb and Ridomil MZ were at par in their effectiveness against fruit rots of brinjal.
