Abstract/Contents:"Natural in-field variability of turfgrass root growth and nematode density makes it difficult to determine effects of nematicide or fungicide treatments applied to manage nematodes or fungal infections that result from nematode feeding. Over the past two years we have analyzed over 1000 soil cores (5-cm diameter by 20-cm depth) from trials on hybrid bermudagrass (Cynodon dactylon ^D#x C. transvaalensis) infested with Belonolaimus longicaudatus or from 'Empire' zoysiagrass (Zoysia japonica) infested with Trichodorus obtusus. Treatments included three different nematicides, a fungicide, and nematicide and fungicide combinations. A 100 cm3 soil sample from each soil core was collected and assayed for nematode density using centrifugal sugar flotation. Roots in each soil core were then washed free of remaining soil, dried for five days at 70°C, and incinerated at 525°C for 3 hours in order to determine dry root weights. To more fully understand the relationship between nematode feeding and root growth, we regressed dry root weight with nematode density. In a separate nematicide trial, we compared the variability of root weights to root architecture. Soil cores (5-cm diameter by 20-cm depth) were collected and roots washed free of soil, scanned on a flatbed scanner, and analyzed for root architecture. Afterwards, root weights were evaluated as described above. Data shows that root architecture may be a better indicator of nematode damage than root weights. Results of the regression analysis will be helpful in understanding treatment effects of this and future nematicide trials."
