Comparative efficacy of Glomus fasciculatum, Trichoderma harzianum, carbofuran and carbendazim in management of Meloidogyne incognita and Rhizoctonia solani disease complex on French bean

The treatment with Trichoderma harzianum @ 1.25 kg/ha and carbofuran @ 1 kg a.i/ha was found to be effective in increasing plant growth parameters and yield of french bean. All the treatments significantly decreased final nematode population in soil except carbendazim @ 0.1%. The treatment with carbofuran @ 2 kg a.i/ha was found to be best in suppressing the final nematode population in soil. Maximum reduction in disease incidence was recorded in treatment with T. harzianum @1.25 kg/ha + carbofuran @ 1 kg a.i/ha.
