EFFECT OF BIO-AGENTS AS SOIL APPLICATION AGAINST ROOT-KNOT NEMATODE, MELOIDOGYNE INCOGNITA INFECTING BRINJAL
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 33
Abstract
An experiment was conducted to find out the effect of both fungal and bacterial bio-agents as soil application on plant growth and reproduction of Meloidogyne incognita on brinjal. For this study, two fungal and one bacterial bio-agents viz. Trichoderma viride, Trichoderma harzianum and Pseudomonas fluorescens were used at 2 g and 3 g per kg soil. A chemical check (carbofuran 3G at 2 kg a.i. per ha) and untreated check were also maintained for comparison. Results indicated that these bio-agents were found better over untreated check (control) in improving plant growth characters and reducing nematode reproduction. Among all the treatments T. harzianum at 3 g per kg soil proved better over other bio-agents. However, the chemical check carbofuran 3G at 2 kg a.i. per ha used as soil application was found the best treatments in improving plant growth characters as well as in reducing nematode population over other treatment. So according to bio-agents its concluded that soil application with T. harzianum at 3 g per kg soil was found best treatment followed by T. Viride and P. Fluorescens 3g/kg soil to enhanced plant growth of brinjal and management of M. incognita.
