Efficacy of neem based products against bacterial blight of clusterbean

Study was conducted to manage bacterial blight of clusterbean through eco-friendly components in kharif 2001 to 2003. Seed soaking with streptocycline @ 250 ppm for 15 minutes followed by two sprays of 3% neem seed kernel extract at 30 and 45 days after sowing gave significantly least bacterial blight intensity (PDI 8.14%) and highest grain yield (1207 kg/ha) with ICBR 1: 7.42 as compared to disease intensity of 26.02 per cent and 910 kg/ha grain yield of untreated control.
