About two years ago, I was on the phone with Dr. Jim Kerns, Dr. Bruce Clarke and other legends of plant pathology, digging into the testing and trials of two new BASF products: Maxtima fungicide and Navicon Intrinsic brand fungicide. 

• An amazing 85% of the superintendents surveyed who have used the products said they were “likely” or “highly likely” to recommend them to their colleagues.
• Dollar spot is an important target, but many users (38%) embraced it as an effective broad spectrum rotation tool.
• Nearly 93% of users were pleased with the products thus far. A quarter of all users surveyed said they already consider it an important part of their disease control program.
• When asked to rate the value of Maxtima fungicide and Navicon Intrinsic brand fungicide overall, supers gave it 4.1 stars out of 5.

I asked Lance Rogers of the venerable Colonia Country Club to describe his experience with the product in one word:

Alan Corbin of Corbin Turf in the Carolinas said it got his attention two years ago when so many great turf researchers were giving it a thumbs up.

“When PhDs like Bruce Martin, Jim Kerns, Bruce Clarke and Rick Latin all say the product is great, you have to sit up and pay attention. Plus, it’s obviously a very rare thing to have a DMI you can use in the summer. I was so impressed that all those professors said Maxtima [fungicide] had zero problem[s] with growth regulation."

“I’m pretty cautious about new products, but I have zero hesitancy recommending this one. Overall, everybody who tried it anywhere this year has loved it. And the price is right, so it works for a lot of people as a broad spectrum control. Even courses with tighter budgets who were only spraying tees and greens can now afford to also spray maybe 10 acres for spring dead spot control in fairways. We also highly recommended it for fairy ring. The biggest thing overall for us down here is we have a new active we can trust in the heat.”

When I talked to him in August, Paul Dotti of the great old Arcola Country Club had just hosted the New Jersey state amateur — in the middle of a pandemic and a hurricane. It was crazy, but the one thing he didn’t have to worry about was disease.

“For a long time, my go-to summer sprays have been BASF products. This year we added Maxtima [fungicide] to the mix as we prepared to host the amateur. We finally sprayed at day 22, right before the event. We probably could have pushed it longer, but I didn’t want to spray during play. It was 90 [degrees] and humid, but it was still doing great. Maxtima [fungicide] was just bulletproof for 21 days during the toughest conditions you could imagine.

“Everybody has products that I like and it’s really amazing that we have so many good products in our arsenal today. But I am excited to have an effective fungicide like Maxtima [fungicide] that I can use with one hundred percent confidence during any kind of weather.”

According to Noble Turf’s Brian Bontemps, it’s all about having a summertime weapon. “The biggest thing Maxtima [fungicide] offers is the ability to have a DMI in the summer. The efficacy and spectrum of it gives [you] a great summer patch product, as well as anthracnose control. And I’ve had no reports of problems, which is amazing considering my supers are saying these are the worst summer conditions they’ve faced in a long time.

“The fact that we can use the products at high rates and still get high efficacy and extended control with zero impact is such a big deal. And it’s hard to imagine they’d come up with something better on [a] cost-per-acre basis. I see it continuing to be a core product for years to come and I can’t wait until it’s approved in New York.”

Jeff Gregos of Pennsylvania’s E.H. Griffith, a rep with extensive experience in testing new products in the turf market, put the products through their paces before he ever recommended them to supers.

Ryan Snowden, a second-generation super, said the convenience and labor-saving factor interested him right away. “When you see a new DMI come to the market, you obviously pay attention. When you can also spray it with growth regulators and it’s safe [for the turf], that really gets your attention. I hate to spray when I can’t put Primo in the tank because it’s expensive and a hassle to do a second spray. We have 30 acres of fairways and it’s essentially a two-day job to do a spray. That’s why I want to put as much in a tank as I can.”

Snowden, who works with his famed father, Buddy, at North Carolina’s Burlingame Country Club, hit his fairways with Navicon Intrinsic brand fungicide in early March to “clean things up a little” and got 30 days of control [over] brown patch and other early diseases. In summer he’s targeting anthracnose and brown patch and getting the results he’d hoped for. “You pay for what you get. Some of the less expensive products work sometimes, and sometimes they don’t. One of our goals on fairways is to get 21 days of control and we’re getting it. It gives you more time between applications, more tank-mixing flexibility and BASF makes good products. I just feel like you get a lot of bang for the buck.”

Josh Kopera, the Harrell’s rep for one of the “ground zero” disease regions in the northeast, is a believer. “Maxtima [fungicide] delivers as promised and the price is really competitive considering the longer intervals. It’s been a very trusted product for us. [Users] won’t have to worry about a rescue and it has zero growth regulation effects. 

“I also like it because it’s a ‘softer’ chemistry. It does its job but doesn’t get angry with the turf. You can’t overlook that. Finally, the price point is amazing and BASF is a trusted name. It’s going to be a valuable product for a lot of years to come.”
