Description:<br />
Recently, Vydate (oxamyl) was registered for use on non-bearing raspberry for the control of<br />
plant-parasitic nematodes in <strong>Washington</strong>, specifically the root lesion nematode, Pratylenchus<br />
penetrans. This means that Vydate can be applied to red raspberry at least 12 months prior to a<br />
harvest (EPA SLN No. WA-120005). This is an important addition to the raspberry growers’<br />
nematode management toolbox, and being able to maximize the efficacy of this product should<br />
provide growers with another way to control nematodes. Pratylenchus penetrans attacks the<br />
roots of raspberry and slowly causes feeder roots to die, limiting the capacity of the plant to<br />
uptake water and nutrients resulting in decline. If P. penetrans is not managed it can result in the<br />
reduced lifespan of a raspberry planting. We propose to conduct on-farm field trials to determine<br />
the best time in the spring after planting to apply Vydate to maximize nematode control. This<br />
