Koenning, S. R., D. E. Morrison, and K. L. Edmisten. 2007. Relative Efficacy of Selected Nematicides for Management of Rotylenchulus reniformis in Cotton. Nematropica 37:227-235. The effectiveness of selected fumigant and non-fumigant nematicides for management of the reniform nematode, Rotylenchulus reniformis, on cotton was evaluated in field experiments in relatively high and low yield environments. Fumigant nematicides 1,3 dichloropropene (1,3-D) or metam sodium provided significant yield increases on cotton, whereas non-fumigant nematicides aldicarb, aldicarb plus oxamyl, or fenamiphos provided variable results. Metam sodium and 1,3-D were equally effective in limiting population densities of R. reniformis at mid-season but final population levels at cotton harvest were unaffected by any treatment. Cotton lint yield was positively related to the application rate of metam sodium or 1,3-D. Cotton profitability was improved by low rates of 1,3-D in a low yield environment, but all rates of fumigants were effective in improving cotton profitability in a high yield environment.
