Development of bio-rational based management technology against foot and root rot and root-knot diseases of cucumber

Abstract

The experiments were conducted in the field of Plant Pathology Division, BARI during 2022-23 and 2023-24 cropping season to develop eco-friendly integrated management technology against foot and root rot disease caused by Fusarium oxysporum and Sclerotium rolfsii and root-knot nematode disease caused by Meloidogyne incognia. Pathogens infested field soils were treated with different treatment combinations of Trichoderma based Tricho-composts, saw dust burning, bio-fungicide Lycomax, poultry refuse, mustard oil cake, chemical fungicide Autostin and nematicide Rugby 10 G. All the treatments gave appreciable reduction of both foot and root rot, and root-knot nematode diseases and thereby enhanced plant growth as well as fruit yield of cucumber. The integration of Tricho-compost with Lycomax effectively reduced the foot and root rot disease upto 85.73% in addition to 44.86% reduction of gall index of root-knot nematodes in cucumber. Combined use of poultry refuses or mustard oil cake with Autostin was also a viable strategy for managing foot and root rot and root-knot nematode diseases in cucumber for enhancing cucumber yield in an eco-friendly manner.
