BASF launches new complete fungicide solution for Irish growers.
Navura® + Comet® 200, offers growers a complete T1 solution for their barley crops.This new pack provides well balanced disease control covering all major barley diseases; Rhynchosporium, net blotch, septoria nodorum, brown rust and ramularia.
Navura® (mefentrifluconazole (Revysol®) + prothioconazole), is a combination of 100 g/l prothioconazole and 50 g/l Revysol®, the 2 key barley azoles. Navura® builds on the proven strength of Revysol® to give excellent efficacy and long-lasting protection.
The addition of Comet® 200, (pyraclostrobin) adds the principal strobilurin for barley, essential to control the net blotch population now dominated by F129L mutation.
Navura® + Comet® 200 joins Balaya® (Revysol® + prothioconazole) + Imperis® (Xemium®), the T2 solution for barley, as an additional Revysol® containing option in 2025.
Navura® formulation enhances performance
The unique formulation of Navura® results in benefits which are greater than the sum of the performance of its active ingredients.
Steve Dennis, Head of Business Development, BASF said, “Navura is not the same as a tank mix of Revysol + prothiconazole. It is fundamentally different in terms of its performance. It’s not just a good formulation, it’s so much more than that, it‘s in the way that we can get the two actives working well together. Revysol interacts with prothioconazole, allowing the prothioconazole to become more active on key diseases.
“It gives exceptional leaf and ear coverage and rapid uptake gets both the Revysol and prothioconazole components into the leaf faster than other prothioconazole products. This ensures better protection from wash-off and UV degradation whilst enabling quicker activation of prothioconazole resulting in enhanced disease activity.”
Powered by complimentary active ingredients
David Leahy Business Development Manager BASF said, “In contrast to last year, crops are coming out of the winter in very good nick. We have seen levels of net blotch, and bits of Rhynchosporium in some varieties over the last few months so you do need a product that will deliver curativity early on in play.”
Applying Navura® + Comet® 200 at T1 will deliver reliability on a broader level giving control of the primary diseases, key to maintaining yield potential in crops and reducing the ramularia pressure later in the season.
David said, “When we talk about managing disease in barley, we talk about a programmed approach. Navura, at T1, with prothioconazole as its backbone and the complimentary activity of Revysol sets a new benchmark for broad spectrum control.
“The two azoles in the Navura co-formulation complement each other in terms of disease control. Prothioconazole is the leading Rhynchosporium azole in barley and gives excellent net blotch control.
“We know Revysol’s strength on ramularia and this T1 solution is going to offer us a head start in that regard. Revysol also has strength on septoria nodorum, a disease that is becoming more common in specific varieties and another disease that you want to manage early on.”
This is all supported by pyraclostrobin in the form of Comet® 200, which as well as disease control also delivers proven physiological benefits, reducing plant stresses. The Navura® + Comet® 200 pack at T1 sets the crop up to deliver.
Independent trials
Bryan Kearney, Trials Co-ordinator, Eurofins said, “We’ve done a lot of work at Eurofins with Navura + Comet 200 and in terms of performance it has been the most consistent barley product in trial over the last 3 years. We have probably tested it under the highest disease pressure going, pressure from a trials perspective we didn’t even think was possible in barley. Navura + Comet 200 gave excellent disease control, from a net blotch and a Rhynchosporium perspective under this maximum disease pressure.”
Barley Agronomy Guide
Growing barley successfully is not all about the chemistry and in order to maximise both winter and spring barley yields it is absolutely crucial to get the basics right. To help growers with this, BASF have created the Barley Agronomy Guide in collaboration with Teagasc, ADAS, SRUC, and NIAB.
