Efficacy of Ethanedinitrile against Pinewood Nematode in Woodchips under Field Conditions

Abstract As the ban on methyl bromide widens, need for an effective phytosanitary fumigant alternative grows. Currently available alternatives, phosphine and sulfuryl fluoride, lack efficacy against pinewood nematode. Ethanedinitrile is a highly efficacious with chemical properties similar to bromide. was tested nematodes in large-scale field setting southern yellow pine wood chips at dose rates of 75 120 g/m3 24 hours. All treatments resulted complete control whereas nontreated confirmed presence live nematodes. These preliminary results confirm ethanedinitrile under conditions.
