Abstract: With the impending cancellation of fenamiphos, new management strategies are needed for plant-parasitic nematodes on turfgrasses. Bran derived from oriental mustard (Brassica juncea) releases the nematicide allyl-isothiocyanate (AITC) upon contact. with water. The dry material can be added topically to turf and the AITC can be moved into the ground during irrigation. Numerous field experiments conducted over a four-year period evaluated the effectiveness of mustard bran for management of Hoplolaimus galeatus and Belonolaimus longicaudatus on turfgrasses. Multiple formulations, rates, and application methods were evaluated on several grass species. Unformulated mustard bran was bulky, caused phytotoxicity, and was difficult to apply. However, improved formulations caused no phytotoxicity, were easier to apply, and reduced population densities (P < 0.05) of H. galeatus and B. longicaudatus in soil. Visual improvement of turf often was pronounced (P < 0.05), especially in sites where H. galeatus was the primary nematode problem. Results of these studies indicate that formulated mustard bran could be an acceptable alternative to fenamiphos for certain turfgrass situations.
