Comparison of bio-agents and botanicals with fungicides against tikka and anthracnose diseases of groundnut (Arachis hypogea L.)

Abstract

Groundnut is an important oilseed crop and contributes about 40 per cent of total oilseed\rproduction in India. Due to its nutritional value and oil production, it is very valuable and\reconomical crop but several diseases like tikka, collar rot, rust, peanut bud necrosis and\ranthracnose take heavy toll every year decrease the yield severely. A field trail was conducted\rin Kharif season in the month of August, 2012 to test the effect of seed treatment with bioagents,\rbotanicals in comparison to chemical fungicides against tikka disease and anthracnose of\rgroundnut to minimize the disease intensity. The treatments were control (water irrigation),\rTrichoderma harzianum 1 per cent, Trichoderma viride 1 per cent, Neem seed kernel extract 5\rper cent, Pseudomonas flourescens 5 per cent, Bavistin 0.2 per cent, Thiram 0.2 per cent, Neem\roil 5 per cent. Seed treatment with Bavistin @ 0.2 per cent was found superior among all the\rtreatments in managing the tikka leaf spot, whereas, neem oil showed better results next to it.\rHowever, anthracnose infection was very little or negligible.
