Abstract
The experiment was carried out in the field of Department of Nematology Odisha University of Agricultural and Technology, Bhubaneswar during the rabi, 2021–2022 to estimate the avoidable yield losses in 12 Patra variety of cucumber due to root-knot nematode, Meloidogyne incognita in nematode infested field. Ten replications of the experiment were set up using the paired plot technique. Required quantity of Carbofuran granules@2kg a.i./ha was applied two days before sowing. Ten plots were treated and another ten plots were kept untreated control (without carbofuran application). The findings exhibited that application of carbofuran significantly reduced the number of galls, egg masses and nematode population -80.01, -84.49, -27.23 respectively. Avoidable yield losses were recorded to the tune of 66.23 percent on cucumber plants by M. incognita.
