Green Waste and Cutless Granular

Cutless Granular reduces growth of landscape ornamentals.  Good, but what does that mean for business? 

Let’s look at one example from a trial in Fort Lauderdale, Florida on a difficult to regulate viburnum hedge.  In this case we’re looking specifically at green waste production in two hedgerows treated with Cutless G vs. two hedgerows left untreated. 

Immediately prior to the trial a landscape crew trimmed the hedgerows to their desired size. An application of Cutless G was then made.  Application timing was February 1, just before spring flush in the Fort Lauderdale area.  After four months of growth the property manager asked that we trim the shrubs because he was receiving excessive growth complaints for hedges not treated with Cutless Granular.  At this point the hedgerow was trimmed back to its original size by the same landscape crew.  Clippings from the treated and nontreated hedgerow were kept separated, collected, then weighed for comparison. 

In area one Cutless Granular reduced green waste production 56%.  In area two, Cutless Granular reduced green waste production 63%, both compared to the nontreated areas.  This is one example of how Cutless Granular will have a direct influence on your bottom line.  Imagine a 60% reduction of all green waste across your properties.  Now that’s a return on investment.

Irrigating with Algae

Patrick Williams is a Golf Course Industry magazine contributing editor.

Sometimes conditions are just right for algae on turf—humid, wet and shady with an abundance of nutrients. For golf courses with irrigation ponds, some of that algae could be coming directly from sprinklers and irrigation heads.

Many superintendents are hesitant to treat their ponds for algae, but they should if they want to prevent algae issues on their turf, says Steve Larose, technical services representative for BioSafe Systems. “If they’re drawing from a pond, then they’re definitely having issues and they’re just basically spreading algae all over their greens whenever they water,” he says.

BioSafe carries the products GreenClean Pro, a granular algaecide; and ZeroTol, a fungicide for turf. The company also has touring technical representatives and an in-house pathologist to address specific issues at courses, Larose says.

Even if there isn’t a noticeable algal bloom in a course pond, or a clog in an intake structure or irrigation head, algae could still be coming through, says West Bishop, algae scientist and water quality research manager at SePRO. “There’s certainly algae that are present in the atmosphere that can just be deposited from spores in the atmosphere, but irrigation is probably a primary route where algae is put right on the turf, and certainly the irrigation, or keeping it moist, can help propagate algae on the turfgrass,” he says.

The SePRO products SeClear Algaecide & Water Quality Enhancer and Captain XTR fight against algae in ponds, Bishop says. Superintendents who want to take a proactive, preventative approach should use SeClear, while those who are experiencing a large growth or bloom should use Captain XTR, he says.

Fairview Country Club in Greenwich, Conn., has had some issues with algae in its ponds over the years, says superintendent Jim Pavonetti. A pond company treats the ponds when necessary, and workers have had luck with a product called Super’s Choice. “That’s a type of bacteria that eats the nutrients that are necessary for the algae to bloom,” he says. “And then we dye the ponds black right before every weekend, and that blocks the ultraviolet rays, which is also necessary for the algae to bloom.”

Algae that spread onto the turf at East Lake Golf Club in Atlanta, Ga., could have arrived there at least in part through irrigation, says superintendent Ralph Kepple. “I’m sure that it has, and we have some algae in our irrigation pond,” he says. “I’m sure that we get some from that. It’s hard to tell, though. Algae is kind of everywhere, and if it gets the right conditions, it’s going to find its way in there.”

Reduced Fertilizer Use in Courses Across U.S.

     Conducted by the Golf Course Superintendents Association of America (GCSAA) and funded by the United States Golf Association, a recent study compared information and samples from 1,500 golf course superintendents over the period from 2006 to 2014. The information and samples gathered were then independently analyzed by scientists at PACE turf and the National Golf Foundation.

     And the study found a broad reduction in fertilizer use. Phosphate fertilizers were reduced most drastically (53%), while potash (42%) and nitrogen (34%) also showed significant reductions. All this results in 80,000 tons of nitrogen, phosphate and potash fertilizers that are no longer being applied annually.

     "This study shows us that the golf industry is doing more with less when it comes to nutrient use on golf courses," said Wendy Gelernter, co-owner of PACE Turf. "The numbers show that golf course superintendents have reduced nutrient use across the board with positive results. Conservation practices accounted for about 90 percent of the reduction in nutrient use."

     "Golf course superintendents are committed to their role as environmental stewards," said Rhett Evan,s CEO of GCSAA. "This national study further demonstrates our commitment to monitor resources used and willingness to implement change for the betterment of the environment."

Repair Systems in Algae

     A new repair system which uses chloroplast extracts and lights to release interrupting sequences from a protein was reported by research specialist Stephen Campbell and Professor David Stern at the Boyce Thompson Institute.

     While many proteins contain extra sequences, called insertions, that disrupt a protein's function, Chlamydomonas reinhardtii has a protein (RB47) that is capable of cutting the extra RNA, effectively removing the unnecessary sequences. It is likely this RNA-cutting protein helps restore function to the protein.

     The addition of insertions and repair systems could be useful for producing pharmaceuticals or protein products, such as cancer drugs, in culture which would otherwise kill the cell. It's also interesting from a purely research-based standpoint. "If it is happening in plants, is it happening in animals?" said Stern. "We're pretty sure that this protein is just one example; that we have only found the tip of the iceberg."
