| Abstract/Contents: | "Torpedograss is a troublesome weed of turfgrasses throughout the Southern United States. The weed invades golf courses and home lawns throughout south Louisiana and severely infests centipedegrass in the New Orleans area. There are currently no cultural practices or registered herbicides that will selectively remove torpedograss in centipedegrass. Previous research indicates that clethodim is an effective herbicide for removing creeping perennial grasses, such as common bermudagrass (Cynodon dactylon) in centipedegrass. However, information concerning the effectiveness of clethodim for torpedograss control is not available. The objective of this research was to evaluate clethodim for torpedograss control in centipedegrass. Field studies were conducted in La Place and Slidell, LA and greenhouse studies were conducted in Baton Rouge, LA to evaluate the use clethodim for torpedograss control in centipedegrass. In field studies, single or sequential applications of clethodim at 0.60 kg ha-1 and sequential applications at 0.30 kg ha-1 were more effective than sethoxydim applications. Torpedograss control with clethodim, however, did not exceed 79%. Torpedograss control with sethoxydim was no greater than 55%. Although still commercially acceptable (< 30% injury), clethodim caused some moderate centipedegrass injury. In greenhouse studies, the effectiveness of several spray adjuvants were evaluated for use in increasing the efficacy of clethodim. Regardless of adjuvant, clethodim at 0.60 kg ha-1 controlled torpedograss better than clethodim at 0.30 kg ha-1 (62 vs 44%). Results of these studies indicated that the herbicide rate is a more critical factor than the adjuvant used." |
