Abstract:
Sunflower necrosis disease (SND) is a new threat for sunflower cultivation in India. The disease was observed during 1997 in Karnataka, a major sunflower growing state of India. Later, its occurrence was reported from almost all sunflower growing states of India, posing threat to sunflower cultivation. Presently no reliable resistant sources are available. The disease being viral in nature is very much difficult to combat by single approach. At Oilseeds Research Station, Latur (M.S.), India, three-year (2002-2004) field experiments revealed that if the sunflower crop is bordered with sorghum, and sunflower seeds treated with imidacloprid (Gaucho 70 W.S., 5 g/kg) along with sunflower spraying with imidacloprid (Confidor 200 S.L., 0.05 percent, three sprays at 15, 30 and 45 days after sowing), the incidence of sunflower necrosis disease can be minimized.
