Tevos® – A new solution for barley crops

0
  • Tevos®, the new cereal fungicide from BASF is now available for use on barley as well as rye, triticale and oats. Tevos® contains the active ingredients Xemium®  (fluxapyroxad), BASF’s best-in-class SDHI, and F500®  (pyraclostrobin) the best strobilurin for barley.

This combination of active ingredients provides exceptional control of the key primary barley diseases Rhynchosporium, net blotch and brown rust and also delivers proven physiological benefits while preserving excellent straw quality, regardless of the disease pressure.

Steve Dennis, BASF’s Head of Business Development said, “Tevos gives growers an exceptional triazole free option for disease control in barley with high rainfastness due to its innovative and proven formulation.”

Mr Dennis said, “Barley matters to us at BASF and a re-evaluation of our exceptionally strong actives for wheat diseases has shown that they also have superior performance on a number of barley diseases compared to the current market standards. These can provide growers with the complete solution for this crop.

“Xemium  is the best SDHI for barley: the strongest solution for Rhynchosporium, building yield and reducing brackling.

“F500 is the best strobilurin for barley: controlling net blotch and brown rust and giving good support for Rhynchosporium. F500 is the most effective active ingredient against net blotch, including the F129L mutation of this disease which is very common in the UK.”

F500® also delivers proven physiological benefits:

•          Enabling the plant to use nitrogen more efficiently 

•          Keeping leaves greener and healthier

•          Preventing physiological leaf spotting

thereby significantly reducing plant stresses.

“Revystar XE contains Revysol (mefentrifluconazole), an isopropanol-azole, which is the strongest azole for barley as it offers the best Ramularia control out of all the azoles.”

Protecting barley crops during their early development stage is essential. Scott Milne, Agronomy Manager BASF said, “Barley is sink limited and so yield is dictated by the number of tillers and ears that the crop maintains. Everything we do with the barley crop early in the season has a knock on effect. By controlling the primary diseases Rhynchosporium, net blotch and brown rust there is a positive effect on secondary diseases such as Ramularia. Using Tevos at T1 sets the barley crop up to achieve its yield potential.

“Growers can’t do much about crop stress caused by the weather, but they can ensure crops establish well and keep them clean and well-nourished reducing the risk of stress later in the season. 

“Not getting on top of disease at T1 risks compromising yield but also puts a strain on the later chemistry. Tevos at T1 sets the crop up to perform.”

Whilst the T1 spray is all about creating yield potential, ultimately the T2 timing is all about maintaining that potential. 

Mr Milne said, “Revystar XE, with its combination of Xemium and Revysol is ideally suited to the T2 timing. Not only does it ensure prolonged Rhynchosporium control, but it also brings straw benefits too. The Revysol component is the strongest active on Ramularia, and it is well known that good Ramularia management can have a positive effect on straw brackling. 

“Brackling is an issue for modern hybrid varieties as well as high yielding spring barley varieties, resulting in difficulties with combining, yield losses and poor straw quality. Straw is a valuable product, especially on mixed farms and Xemium continues to set the standard on reducing straw breakdown.”
