Management ofMeloidogyne incognita by chemigation with fenamiphos was studied in an infested field planted to M. incognita-suscepfible yellow summer squash cv. Dixie Hybrid. Fenamiphos (VL 73.1% a.i. manufacturing concentrate in propylene glycol) was mixed with Unitol DSR-90 or used as fenamiphos 3 SC (spray concentrate). Both formulations, applied with 63.5 kl irrigation water per hectare, dec...
