In 2012, theWashington raspberry (Rubus idaeus) industry received a special local needs (SLN) 24(c) label to apply Vydate L (active ingredient oxamyl) to nonbearing raspberry for the management of Pratylenchus penetrans. This is a new use pattern of this nematicide for raspberry growers; therefore, research was conducted to identify the optimum spring application timing of oxamyl for the suppression of P. penetrans. Three on-farm trials in each of 2012 and 2013 were established in Washington in

at the same time as pulse irrigation (Drip =P). The experiment had eight replications per treatment and also included a PPI reatment of oxamyl (22.5 kg a.i./ha) and a nontreated control. Compared to the control, neither the oxamyl nor the fluensulfone PPI treatments reduced root galling by Meloidogyne spp. in cucumber. Among the drip treatments, Drip NP and Drip +1P reduced root galling compared to the control. Cucumber yield was greater in all fluensulfone treatments than in the control. In a

restrictions have left oxamyl, a carbamate, as the remaining non-fumigant nematicide among older chemistry classes still labelled for tomato production in the United States.
Because of the reliance on a small selection of older nematicides, the development of new tools for SRKN management is important. One group of new tools are the benzamide, non-fumigant nematicides, such as fluopyram. Fluopyram is a succinate dehydrogenase inhibitor (SDHI) that was first used as a fungicide (Cordova et al., 2017; Kandel

current work was to investigate whether pre-exposure of P. penetrans spores to two nematicides (fluazaindolizine and oxamyl) would affect both (i) the subsequent in vitro spore attachment to J2 as well as (ii) affect the infection of nematodes by the bacterium.
Materials and methods
Spore attachment to juveniles after pre-exposure to nematicides
The experiments evaluated different rates of the nematicides and different incubation times, and conducted in two years (2018-2019). The P. penetrans used
