Title: Translocation of Nematicide Residues in Mushroom Following Their Application at Composting
Authors: N. Bahl and N.P. Agnihotri
Nematodes infest and damage the established mycelium m compost resulting considerable reduction in crop yield. Several instances have been reported m India where nematodes were responsible for total crop failure (Bhardwaj et al., 1972; Thapa et al., 1977). Nematodes are introduced into the compost alongwith wheat straw used as raw material for making compost. Although, most of the nematodes are killed during composting by the heat of compost. Some who survive in the cooler part of the stack proliferate and multiply rapidly after spawning. Nematodes, once established into the spawned or cropping trays are very difficult to eliminate. Heat treatment, though gives very satisfactory results (Cains and Thomas, 1950; Bukowski, 1964) but is a cumbersome and expensive method. Most of the small growers cannot afford the costly facilities required. Hence, chemical method is the only alternative which is easy and economical. Many nematocides have given satisfactory result as far as control of nematode is concerned. However, not much information is available on residues of these nematocides that may remain m the compost and later get translocated into the mushrooms. The present study was, therefore, conducted to determine the bioefficacy of aldicarp, carbofuran and quinolphos and translocation of their residues in mushroom crop.Please login to download the PDF for this proceeding.
