Abstract:
Tomato crop is attacked by number of fungi, bacterial and viral diseases. Disease is major constrains in economic crop production as they inflict heavy losses. Among all the fungal diseases early blight of tomato (Alternaria solani) has currently become one of the most important disease of all tomato varieties. Therefore present investigation was under taken for the management of early blight using cow urine, cow dung, vermi wash, bio-agents, eucalyptus oil and fungicide (treated as check) for their efficacy under in vivo treatments were evaluated on different growth and yield parameters of tomato crop under field conditions at Prayagraj during Rabi season 2020-2021. Maximum Plant height @90DAT (60.58cm), maximum number of branches @90DAT (60.58). Trichoderma harzianum was found effective against reducing the disease intensity @90DAT (31.50%) Followed by cow urine, vermiwash, eucalyptus oil compared to Azoxystrobin (check) and control. The maximum yield was found with Trichoderma harzianum (16.01t/ha), eucalyptus oil (15.53t/ha), cow dung (15.45t/ha) as compared to Azoxystrobin (treated check) (18.83t/ha) and control (5.35t/ha).
