Arrowhead Engineered Products acquires Red Hawk


Editor’s Note: BASF and Golf Course Industry are working together to tell the story of the birth of three new products for the golf market. This is the second installment in a three-part series. The first part appeared in the April issue.

They listened, researched, developed, submitted their work for testing, and reviewed the encouraging results of those trials. The BASF team involved in the creation of the fungicide Encartis then spent more than a decade waiting to share their linear triumph with the golf industry.

“One of the things we kept hearing,” says Kyle Miller, BASF’s senior technical representative, “is that Encartis is the best fungicide ever released because people didn’t think we did. would market.

Better. Fungicide. Never. Spear. Quite a description. A good reason why this description went on for a decade.

“One of the reasons we decided not to market it was that we had Xzemplar,” Miller says, “and Xzemplar changed the dollar spot check. “At the time, BASF also had another successful innovation in the works in Maxtima® fungicide, a broad-spectrum, summer-safe DMI that was launched in 2019. Amid all these innovations, BASF n hasn’t stopped thinking about new solutions to help end users.

Building on the success of Emerald® fungicide and the widespread adoption of Xzemplar® fungicide and Maxtima® fungicide, BASF decided to make Encartis ™ fungicide its latest tool against leaf spot and leaf diseases. layout of golf courses. The company introduced Encartis fungicide in July and the fungicide is available for purchase from September as superintendents reflect on 2022 advance order program decisions.

The origins of Encartis fungicide are from Emerald fungicide, an SDHI labeled for dollar spot control launched in 2003. Boscalid, the active ingredient in Emerald fungicide, is also an active ingredient in Encartis fungicide. “Emerald is an integral part of our situation with Encartis,” says Miller, who has been involved in 15 product launches in over three decades with BASF. “In Emerald’s early years, people were like, ‘Well, that would be nice if it got other diseases under control. It would be nice if it worked in a curative way. And that’s what prompted us to turn to Encartis. There were a few things we thought we could improve upon and here we are. “

Encartis fungicide is a premixed formulation, containing a second active ingredient in chlorothalonil. The presence of two active ingredients enables Encartis fungicide to provide preventative and curative control of diseases beyond dollar spot, including anthracnose, brown patch and gray spot. Encartis fungicide is positioned as a fairway disease control product, although, according to Miller, “there are other places on a golf course, such as greens and tees, where it can be placed simply on the golf course. cause of the diseases he catches. “

BASF has worked with university researchers on extensive research on Encartis fungicides in contrasting environments. North Carolina state professor and extension specialist Dr. Jim Kerns performed dollar-for-dollar testing on cool-season turf during his tenure at the University of Wisconsin-Madison. Kerns moved from Wisconsin to the state of North Carolina in 2012 and continued these trials in parts of North Carolina using preventative applications with a disease prediction model.

“With our trials at the University of Wisconsin, it was a different environment, and we usually got 21 days of testing,” says Kerns. “I have always been a supporter of anything dictated by the pressure of disease and the environment. There are times when 28 days won’t be enough because the dollar spot comes and goes. If you pick the right time and use some type of forecasting system, you can easily get 21 days of control. We did follow-up testing with Encartis in the mountains of North Carolina and we got 21 days. This is quite remarkable, as some of these areas get 60 to 70 inches of precipitation each year and getting 21 days is exceptional.

Purdue University Professor Emeritus Dr Rick Latin first observed the fungicide Encartis before the solution was known as Encartis.

“It first appeared in our research program as a numbered compound, but we knew it was a combination of boscalid and chlorothalonil,” says Latin, who remains active in the industry as a turf consultant living in Pinehurst, NC. “This has proven to be very effective in terms of disease control for the dollar spot.”

Multiple benefits exist by combining two proven active ingredients such as boscalid and chlorothalonil.

“The first is simple,” adds Latin. “By increasing the spectrum of activity, you reach more target pathogens. But I really think the most important benefit is the increased processing power. Two active ingredients attacking a fungal cell at different targets will ensure a greater likelihood of cell death. The more we reduce the number of pathogen cells, the more we reduce the populations of pathogens – and reducing the populations of pathogens is the key to longer control periods. In terms of combining these two active ingredients in an optimized formulation… I think this is something that is long overdue in our industry.

Under sweltering conditions in South Carolina, Clemson University Professor Emeritus of Turf Pathology, Dr Bruce Martin, began studying Encartis fungicide in 2009 on bentgrass ‘Crenshaw’ greens. Encartis fungicide was only a numbered compound at the time. Martin says his team chose ‘Crenshaw’ to conduct the trials because the variety “is perhaps the most sensitive bentwood we have ever seen for the dollar spot.”

“We did this on purpose,” he adds. “If there’s a weak spot in a dollar spot fungicide, it would come out in ‘Crenshaw’ and we could spot it. We also have other diseases on the greens because we are in a more humid and warmer environment in the summer, so we have anthracnose that can get into the bentgrass and we have the brown patch. The addition of chlorothalonil helps fight a wide range of diseases that we can see on bentgrass greens.

When and how is Encartis most effective? See him as a potential attacker for control of the dollar spot.

“For cool season fairways, we have a wide range of active ingredients that we can use in a rotation in the Midwest and Northeast where the dollar spot is particularly troublesome,” Latin said. “I would position him at the start of the season. You have chlorothalonil as a protector and you have boscalid which attacks any infection that may have occurred, keeping the population low. You can switch at any time of the season, but it is advisable to proceed early in the season for this first application. “

Encartis fungicide can also be the damn # 9. Miller calls the first and last sprays of the season “the basis of everything that happens in the middle,” and he says Encartis fungicide works well in both locations. .

“This bookend program we’re talking about is off to a good start, putting Encartis before you have any disease issues, so you stay clean at the start of the season and then at the end of the year, we want go into the offseason with really healthy and beautiful turf, “Miller adds.” It nails the end of the year. That’s how I think of a bookend program,… it sets you up for success.

In the case of Encartis fungicide, it has been a long overdue contributor to golf course success.

What about warm season sod?

Yes, it is possible to use Encartis fungicide on warm season turf. Let Clemson University Professor Emeritus of Turf Pathology, Dr. Bruce Martin, explain.

“The adjustment is going to be on the greens,” he said. “We see dollar spots on Bermudagrass leaves and they are sometimes misidentified as leaf spots, and the two diseases occur simultaneously on Bermudagrass leaves. Chlorothalonil has activity on both pathogens. On other warm season grasses we see a dollar spot on zoysia and there is growing interest in zoysiagrass greens in the south. I can see a good fit there, almost similar to what you might have on bentgrass greens, because zoysiagrass is more susceptible to dollar spot than Bermuda grass. Seaside paspalum is an important turf in various parts of Florida and the dollar spot is probably the # 1 disease of seaside paspalum, so it would have similar uses to what you would see on a fairway in Florida. bentgrass in the northeast.
