Trunk growth between February and June of trees in the nematicide trial did not differ significantly. However, growth rates for all nematicide treatments were nominally higher than for the untreated trees. Growth for a Syngenta experimetal nematicide was 40% greater than the control, and the oxamyl, aldicarb, fluopyram and, fluazaindolizine were between 17-20% greater than the control. There was a weak inverse relationship (P = -0.09) between the trunk growth and the May sting nematode populations, measured following the nematicide treatments. The root weights ranged between 0.28 and 0.37 mg dw/g soil fw and did not differ between treatments. Sting nematode populations were significantly lower (P = 0.04) in perennial peanut plots (6 nematodes/250 cc soil) than in control plots (23 nematodes), 5 months after laying the peanut sod. Fall 2019 nematicide treatments were initiated in September and will continue throughout October. The materials are being injected for two hours, begining 30 minutes after irrigation begins. The plots are irrigated for a further 30 minutes following the nematicide applications.
