Field investigations showed that the nematode DD-136 would kill Rhyacionia frustrana (Comstock) larvae under natural conditions. More first-generation tip moth larvae were killed than second or third. Nematode suspensions were aided in effectiveness by addition of 10% glycerin and to a lesser degree by addition of wetting agents or spreader-stickers, namely, 2% solution of Emgard 2050, Sole-onic CDS, and IGEPON AP-78. However, it was concluded that under the conditions of this study, DD-136 did not provide sufficient control of the Nantucket pine tip moth to recommend its use.
