Abstract:

Tomato (Solanum lycopersicum L.) is the third most important crop in India that suffers from various biotic and abiotic stresses. Among the biotic stresses early blight caused by Alternaria solani [(Ell. and Mart.) Jones and Grout] is one of the most destructive diseases of tomato which leads losses up to 78 per cent. In the present study efficacy of cow by product and fungicides were evaluated against the pathogen in vitro and in vivo conditions. Among cow by products, cow urine showed the maximum growth inhibition of 78.44 per cent (20% concentration) in vitro. Among fungicides, Propiconazole 250 EC showed maximum growth inhibition of 96.67 per cent (250ppm) followed by Mancozeb 50%WP which showed growth inhibition of 84.44 per cent in vitro. To validate the efficacy of cow by products and fungicides, a trial was also conducted in the field conditions also. It was found that foliar application of Propiconazole @ 0.2% was found highly effective as it gave minimum disease intensity (6.5 percent) and maximum fruit yield (17.77 t/ha) and 10% concentration of combined effect of seed treatment and foliar application of cow urine was most effective as it gave minimum disease intensity (28.70 percent) and maximum fruit yield (14.72 t/ha). The effective components found in this study can be utilized as integrated disease management for Alternaria solani or early blight of tomato.
