Abstract/Contents:"Sting nematode (Belonolaimus longicaudatus) is particularly devastating to turfgrass areas constructed on high sand content rootzones. Biochar and compost have arisen as potential control options for nematodes in various cropping systems. A study was initiated in August of 2021 exploring how soil amendments impact the movement of nematodes in the rhizosphere of ultradwarf bermudagrass. The experimental site consisted of a bermudagrass putting green maintained at the Pee Dee Research and Education Center in Florence, SC selected for its pre-existing sting nematode population. Amendment treatments were arranged in a randomized complete block design with 4 replications and 3 sub plots within each replicate 0.3 by 0.7 m plot. Each subplot consisted of one 10 cm circular plug removed to a depth of 20 cm. Original rootzone material and roots were removed from the 5-20 cm depth for replacement amended rootzone treatments before replacing the 0-5 cm deep turf plug containing mostly thatch and root material. Rootzone treatments included 20% red sedge peat/80% sand mixture, a 20% biochar compost blend/80% sand mixture, 100% sand mixture, and a 10% biochar compost blend/10% red sedge peat/80% sand mixture. The experiment was replicated over time in additional sting nematode infested greens across 2022. Destructive samples were taken from the sub plots every 3 months to monitor nematode population. Plots were assessed regularly for turfgrass color (i.e., Normalized Difference Vegetation Index). All data was subject to analysis of variance using the mixed procedure in SAS 9.4. Treatment means were separated using Tukeys honest significant difference at 0.05 probability. Sting nematodes were observed above threshold for samples collected throughout the study period, yet rootzone treatments did not impact sting nematode populations. Preliminary analysis showed turf quality of plots treated with 20% biochar compost blend/80% sand mixture to have significantly higher turf quality compared to 100% sand treatment."
