Efficacy of bio-pesticides along with plant product against the incidence of leaf eating caterpillar and stem borer in soybean

Abstract

An experiment was conducted during kharif season of 2015 on soybean crop to test the bio-efficacy of bio-pesticide along with plant product against leaf eating caterpillar and stem bore. The result revealed that two spray of trizophos 40 EC proved to be the most effective against all the larval population followed by first spray of neem oil and second spray of triazophos. The highest net profit and incremental cost benefit ratio was observed in plots treated with triazophos Rs.10425/ha and 1:5.36) followed by Beauveria bassiana (and) triazophos (Rs. 8410.46/ha and 1:4.26). The maximum seed yield of 964.45 kg/ha was recorded with the application of two sprays of triazophos. The minimum yield was recorded in plot treated with two spray of Metarhiziumanisopliae (826.89 kg/ha).
