Abstract

Phyto-nematodes are very costly burdens of crop production with considerable impact on tomato grown in all the regions of the valley. Therefore, the present investigation was conducted during 2019-20 with an objective to make a general survey of these parasites on tomato by analysing the soil and root samples of the host and to study their average prevalence from the valley and to sort out a possible management strategy to reduce the parasite burden on the host for the effective production. Filenchus (Andrassy, 1954) Meyl, 1961 was met with 83.3 % of absolute frequency, 27% of absolute density and 84 as the mean intensity value. It was found that the population density of this nematode was reduced by the organic amendment to a varied extent and poultry manure and walnut leaf extract caused considerable reduction of nematode populations.
