NEMATODE CONTROL IN COTTON WITH PLANTING AND POST-PLANTING APPLICATIONS OF NEMOUTTM (PAECILOMYCES LILACINUS STRAIN 251).

NemOut™ is a new nematicide in development for use on cotton and peanuts. NemOut contains an EPA registered bio-rational fungal nematicide formulated for applications at planting, side dressing and through overhead irrigation. This new product, based on Paecilomyces lilacinus strain 251; is being evaluated by public researchers throughout the mid-south and southeast and is being commercially introduced by Plato Industries of Houston, Texas. The active ingredient in NemOut has been developed and is produced by ProPhyta GmbH of Germany and is presently labeled for use on a variety of vegetable crops and for turf use. The registration process for cotton and peanuts is underway and registration was received in late 2007. NemOut has activity against reniform, root knot and lance types of nematodes. Field tests were conducted in 2006 and 2007 to evaluate different application strategies for NemOut. Application in cotton using liquid fertilizer equipment and timed during the 4-7 leaf growth stage consistently increased cotton yields compared to no treatment of when applied following the use of a nematicidal seed treatment.
