Spot drip application of dimethyl disulfide as a post‐plant treatment for the control of plant parasitic nematodes and soilborne pathogens in grape production

Abstract

Post-plant fumigation with DMDS controlled plant parasitic nematodes in established grapevines but was less efficacious against soilborne pathogens. Low rates of DMDS were sufficient for nematode control and increased the grape yield, probably without affecting beneficial soil organisms. Further research on evaluating the potential effect of DMDS against beneficial soil organisms is needed.
