On turf areas that require heavier applications because of drainage issues or high traffic, the CR-15 smart controller can allow operators to increase the spread rate as needed, all at the push of a button. This capability applies to areas with variable soil profiles as well as others, like ball landing zones. Visit Turfco, www.turfco.com. Air-O-Lator revealed its latest addition to an extensive line of Font'N-Aire fountains. The Nu-Wave decorative floating fountain system is designed for applications where electrical power entering the water is prohibited or not desired. This fountain is designed to operate without an electrical motor or wire in the water. The Nu-Wave is designed with shallow applications in mind and can run in water as low as 9 inches deep. Water is pumped from the body of water through a centrifugal pump and then back to the fountain through a minimum 2-inch flexible hose. The Nu-Wave has no moving parts that can become fouled from debris, so there's no need for electric- ity to enter the body of water and, therefore, no possibility of clogging. The Nu-Wave is perfect for shallow irrigation ponds, stormwater retention ponds, ponds with heavy debris or swimming areas, or any application. The Nu-Wave fountain consists of a float, a mounting disc, a 2-inch hose adaptor, a water plenum and one of Air-O-Lator's standard five decorative nozzles and a transfer pump located outside of the body of water. Visit Air-O-Lator, www.airolator.com. Target Specialty Products launched Turf Fuel Root Down 18-0-0, a product for turf professionals to strengthen plants, fight sodium and bicarbonates and enhance turf color. Turf Fuel products are designed to help turf professionals get the most out of their turf even in extremely stressful conditions. A combination of acidified nitrogen, micronutrients and a strategic amount of surfactant, Root Down is designed to be applied as a routine nitrogen source or an advanced sodium and bicarbonate remediation tool. The product is derived from a unique nitrogen compound that provides multiple secondary benefits beyond nutrition, the company says. It is composed of several cutting-edge components aimed at strengthening plants from the root up. Visit Target Specialty Products, www.target-specialty.com. Nufarm Americas announced that Safari 20 SG Insecticide has received a 24(c) label for the control of spotted lanternfly in New York. This follows 2ee label approval to control spotted lanternfly in 15 states: Connecticut, Delaware, Kentucky, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, North Carolina, Pennsylvania, Rhode Island, Tennessee, Vermont, Virginia and West Virginia. The spotted lanternfly is an invasive plant-hopper quickly invading, and spreading in, the northeastern U.S. The pest impacts more than 70 host plants and, if infested, can result in significant damage and loss to nursery operations. Safari 20 SG supplemental labels are approved for use in containerized and field-grown (in-ground) ornamental plants in nurseries, outdoor landscapes, tree plantations and reforestation nurseries. It includes national, private and state forests and wooded areas. The label provides application alternatives that include foliar spray, media drench, soil drench or basal trunk spray. Safari is a super- systemic insecticide with quick uptake and knockdown of tree, shrub and herbaceous ornamental pests. It controls a broad spectrum of invasive pests, including Q- and B- biotype whiteflies, emerald ash borers, mealybugs, leafhoppers, leafminers, and armored and soft scales — and now nymph- and adult-stage spotted lanternflies. To help golf course superintendents monitor for dollar spot, the most prevalent disease on courses nationwide, Syngenta has enhanced its dollar spot alerts. Based on the Smith-Kerns Dollar Spot Model, the alerts offer season-long text and email notifications and the ability to forecast disease development risk five days into the future. Superin- tendents may sign up at www.greencastonline.com/dollarspot to be notified by email or text when conditions in their area are conducive to dollar spot development. The dollar spot prediction model was developed by Damon Smith, Ph.D., associate professor and Extension specialist, University of Wisconsin-Madison, and Jim Kerns, Ph.D., associate professor and Extension specialist, North Carolina State University, along with researchers in Wisconsin, Oklahoma, Pennsylvania, Mississippi, Tennessee, Connecticut and New Jersey. It uses weather indicators to predict when conditions will be conducive to dollar spot development. "The model itself is basically a logistic equation that you plug in the parameters, such as relative humidity, mean and max air temps, as well as how much risk you're willing to take — 20%, 30%, 40%, whatever it might be," Kerns explains. "Essentially, it spits out a probability of whether or not you're going to have disease. One of the things we are most proud of is it allows superintendents at their own facility to de- cide for themselves how much risk they are willing to accept. In our research, we found that 20% was the most accurate prediction." Once superintendents sign up, they will receive a notification when dollar spot pressure in their area is forecast to reach a 20% percent risk threshold in the next five days, which will help them prepare for a preventive fungicide application. After the first alert, superintendents can also elect to be notified of their dollar spot risk at 7-, 14-, 21- or 28-day intervals. The website provides more dollar spot resources, including trial data, researcher interviews and control options, including Posterity and SecureAction, the latest dollar spot fungicides from Syngenta.
