Pacific shoot‐gall disease control in annual bluegrass putting greens using a new formulation of abamectin
نویسندگان
چکیده
The Pacific shoot-gall nematode (Anguina pacificae Cid del Prado Vera & Maggenti, 1984) is a devastating pest on annual bluegrass (Poa annua L.) putting greens in coastal Northern California, USA. Frequently used plant protection compounds such as fenamiphos and azadirachtin are either no longer registered or very expensive have often resulted suppression at best. A new formulation of abamectin (Divanem®; Syngenta, Greensboro, NC) was tested two rates (0.15 0.30 kg a.i. ha−1) application frequencies (2X vs. 4X) comparison to fluopyram (Indemnify®; Bayer CropScience, St. Louis, MO) applied the rate 0.5 ha−1 three California golf courses: Pasatiempo, Santa Cruz; Laguna Seca, Monterey; Del Monte, Monterey. Fluopyram showed best efficacy regarding recovery from against disease. Generally, only applications were required for season-long protection. Four high necessary achieve similar fluopyram. Overall, represents another tool that offers treatment alternative management this pathogen. Neither product had much effect populations soil-dwelling A. pacificae, spiral (Helicotylenchus spp.), ring (Criconemoides root-knot (Meloidogyne spp.) nematodes.

Developing Best Management Practices for Anthracnose Control on Annual Bluegrass Putting Greens: Summarizing Four Years of Field Research
Anthracnose is a destructive disease of weakened or senescent turf caused by the fungus Colletotrichum cereale. The disease occurs throughout the world on almost all turfgrass species but is particularly severe on annual bluegrass (Poa annua L.). It has been suggested that management practices commonly employed on golf courses may be enhancing abiotic stress and thus predisposing turf to anthra...

Tradi t ional weed control in agric u l t u r e ha s b e e n a c c o m p l i s h e d primarily through the use of chemical herbicides and cultivation. Cultivation practices are of little use for weed control in turfgrass management. Turf managers, therefore, tend to rely heavily on chemicals for weed control. Chemical herbicides tend to exhibit rather broad spectrum characteristics. Two common ...
متن کاملMoss Control in Creeping Bentgrass Putting Greens
Moss (Bryum argenteum) continues to become one of the most problematic weeds in creeping bentgrass (Agrostis palustris) putting greens. Control of moss can be approached in many different ways, including chemical applications, and cultural practices such as correcting shading or poor drainage. A study was conducted at Springdale Country Club (Springdale, Ark.) to evaluate the effectiveness of s...
متن کاملEstablishing and Trafficking New Bentgrass Putting Greens
Establishing and Trafficking New Bentgrass Putting Greens Golf turf managers are pressured from the golfing community to reduce the establishment time of playing surfaces. To this end, accelerated grow-in procedures are implemented that eventually permit play on surfaces that are less than prepared to receive traffic. Research hassuggested that accelerated grow-in procedures and premature traff...
متن کاملGreens-type Annual Bluegrass Resistance to Abiotic and Biotic Stresses during Winter
Unseeded annual bluegrass (Poa annua L.) is an important component of golf greens in many regions of northern countries. Although this turfgrass species has desirable playing attributes, it suffers from susceptibility to environmental and biological stresses including subfreezing temperatures, anoxia, and snow molds. During the last decade (1999-2008), we undertook a series of experiments to be...
