P.15. Management of sesame phyllody disease by vector control

A field trial was conducted at Regional Research Station, Vriddhachalam under the control of Tamil Nadu Agricultural University, Coimbatore, with two modules (viz.,) M₁ – Consisting of seed treatment with thirm (0.2%) + Carbendazim (0.1%), Combined with spray of Mancozeb (0.25%) + Endosulfan (0.07%) at 30–40 and 45–55 days after sowing and M₂ consist of farmer's practice (No spraying). Each module was tested in larger area (200 sq.m.). Observations on incidence phyllody diseases (transmitted by jassid orosius sp) root rot and grain yield were recorded. It was observed that the M₁ module recorded the lesser incidence of phyllody (3.42%) root rot (16.9%) and higher grain yield (663.5 kg/ha) then the module M₂ farmers practice consists of no seed treatment and no spraying. It has recorded the maximum incidence of phyllody (14.10%), root rot (38.75%) and minimum grain yield (430.0 kg/ha). The result concluded that seed treatment with thiram 0.2% + carbendazim (0.1%) combined with spray of mancozeb (0.25%) + Endosulfan (0.07%) was effectively control the vector transmission of phyllody disease.
