When turf roots are damaged by nematodes, the plant is unable to absorb water and nutrients effectively from the soil. A damaged root system also weakens the plant and decreases its ability to defend itself against biotic and abiotic stress like heat, drought and disease, which can negatively impact turf quality.

Rain Bird Golf introduced a new Sod Cup Kit that reduces the risk that rotors will negatively impact play on closely mowed approaches to golf course greens. The kit also makes it possible for superintendents and their teams to spend less time trimming around rotors, freeing them up to work on other tasks. Installing the kit on Rain Bird 551 and 700/751 Series rotors is a simple process that can be done by hand. Because the sod cup is the same size as a standard golf-hole cutter, it's easy to quickly cut sod that's just the right size and shape to fit firmly and securely within the cup. After installation, when the rotor is popping up or retracting, its self-flushing action sends a burst of water through the case. This flushing action simultaneously protects the rotor's internal components from debris and irrigates the turf growing in the sod cup. Visit Rain Bird, www.rainbird.com/golf. To help golf course superintendents better manage dollar spot all season long, Syngenta has launched a new solutions-based website, GreenCastOnline.com/ dollar-spot-solutions, which includes a dollar spot prediction tool, trial data, videos and more. These new resources allow superintendents to actively monitor their courses for dollar spot development and stay up to date on the latest dollar spot solutions, research trials and agronomic program recommendations. "Research has shown that 43 percent of surveyed superintendents want more solutions to control dollar spot, more than any other disease," says Stephanie Schwenke, turf market manager for Syngenta. "To help meet those needs, we developed these online resources and delivered two innovative new fungicides, Posterity and Secure Action, to help control dollar spot." The dollar spot prediction tool is based on the model developed by Damon Smith, Ph.D., and Jim Kerns, Ph.D., et al. It helps predict the likelihood of disease development by using local, real-time weather data and disease thresholds. Superintendents can use that data to plan their fungicide applications accordingly. Through Syngenta, superintendents can also sign up to receive email alerts when their area reaches a recommended 20 percent risk threshold, and weather conditions are conducive to dollar spot. Additionally, superintendents can explore an interactive map that highlights extensive dollar spot trials and includes interviews with well-known turfgrass researchers and dollar spot experts. They can also learn about best practices for resistance management and earn GCSAA education points by watching a dollar spot webinar. Visit Syngenta, GreenCastOnline. com/dollar-spot-solutions. SiteOne Landscape Supply released Lesco CarbonPro-L with MobileEx , a liquid biological soil amendment. CarbonPro can be tank-mixed with fertilizers, herbicides and insecticides when applied to turf and landscape plantings. The multisolution product deepens and strengthens roots, helps with stress recovery and pre- vention, improves greening, assists with seed establishment and provides other benefits, the company says. The key to CarbonPro is its exclusive active ingredient formulation, including MobilEX nutrient transport technology, humic substances and kelp extract to maximize plant health. In tests, CarbonPro promoted 75 percent more root mass under 30 percent less nitrogen than positive and nega- tive controls in tall fescue. "A nutrient transporter like CarbonPro can boost nutrient uptake in plants by 30 to 35 percent and maximize ROI. It's not only a significant enhancement to current nutrient programs, but it can be used during fertilizer restriction or blackout periods because it contains no N-P-K," says John Gertz, vice president of category management-agronomics at SiteOne Landscape Supply. Other benefits of using CarbonPro as part of a nutrient program include: reducing operation costs spent on treating turf stress; preventing chlorosis in turf; support- ing establishment of new turf through accelerated seed germination; and increasing turf quality through remediation and restoration from saline soils and salt toxicity. CarbonPro was tested in university trials at the University of Wisconsin and Auburn University and was field tested by Agricen Sciences and Turf Care Supply Corp. laboratories. The product is available in 1-gallon, 2.5-gallon and 30-gallon quantities, with 275-gallon available upon request. Visit Lesco, www.lesco.com. RainBird
