Reniform Nematode Management on Cotton with VRT and Site Specific Applications
|
ABSTRACT A test was conducted in 2001 to examine the benefit of variable rate applications of the nematicide Vapam for the management of the reniform nematode (Rotylenchulus reniformis). Treatments included Vapam applied at the conventional rates of 3.0, 5.0, and 8.0 gallons per acre and a variable rate application of 3.0 to 8.0 gallons based on nematode population numbers. Vapam was injected 16 inches deep in the row 14 days prior to planting. Cotton lint yields averaged 926.18 lb per acre in all Vapam treatments. Yields were 744.24 lb per acre where no nematicide was used. The highest yields of 939.40 lb of lint per acre was recovered from the 3.0 to 8.0 gallon per acre variable rate application of Vapam. |
