Efficacy and Residue Comparisons between Two Slow-release Formulations of Fluridone
Residue profiles and efficacy of Avast and Sonar, two slowrelease pellet formulations of fluridone {1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenly]-4(1H)-pyridinone}, were comparedin outdoor tanks. Hydrilla (Hydrilla verticillata (L.f.)Royle) and southern naiad (Najas guadalupensis (Sprengel)Magnus) were treated with a split application of 6, 12, 18 and24 μg/l a.i. fluridone and the concentrations of both formulationscompared over a 134-day period. Both pellet formulationsexhibited very similar residues over time for eachrespective treatment, resulted in peak concentrations of fluridone40 to 50 days after application, and effectively andsimilarly controlled southern naiad and hydrilla at all ratestested by 92 days after initial application.
