Currently the most common means of reniform management is with the addition of nematicides. The collection of a representative number of soil samples is a limiting factor for any nematode management program especially for site-specific placement of nematicides. In Mississippi, remotely sensed hyperspectral imagery has been correlated with reniform nematode population levels to obtain an accurate estimation of the infield nematode distribution without taking a soil sample.Recent studies in Louisiana have demonstrated that nematicides have been less effective relative to soil EC measurements. Current observations are that higher EC measurements or soil texture the less effective the nematicide. This indicates that soil properties have a major impact in nematicide response. This will provide the producer with a more accurate nematode distribution across the field. Alabama is working with the Greenseeker. The Greenseeker emits its own light source, allowing for on-the-go collection of NDVI readings regardless of cloud cover. This may help provide our producers with real-time readings to help in the delay from aerial imagery.
