Ahead of the critical spring spraying season, Adama has launched three new fungicide co-formulations in the UK, all of which contain the active prothioconazole partnered with either an azole, an SDHI and a strobilurin.

Azole

The first is Maganic – a two-way azole mix of prothioconazole and difenoconazole – which is seen as the ideal tebuconazole-free option for the T3 timing in wheat.

Adama fungicide technical specialist Andy Bailey says the product offers strong protection against a range of wheat, barley, rye, triticale and oilseed rape diseases. 

“Maganic provides reliable control of all major ear diseases, as well as brown rust and septoria, and, like our straight prothioconazole fungicides, it uses our Asorbital formulation technology to deliver faster protection,” he says.

The formulation technology uses a patented solvent and adjuvant system to improve uptake of active ingredients into – and migration within – leaf tissue, explains Andy.

This novel technology not only provides faster protection against key pathogens, but also helps to improve rainfastness.

SDHI

The second new fungicide is Avastel, which provides protection against a broad spectrum of foliar and stem base diseases.

This time, prothioconazole is partnered with the SDHI fungicide fluxapyroxad.

The product – also manufactured using Asorbital technology – can be applied to wheat at the T1, T2 or T3 timing, and in barley at T1 or T2.

Andy says: “It demonstrates broad spectrum control of key foliar and stem-base diseases in wheat, and is effective against brown rust, yellow rust and tan spot.

“It also provides good protection against net blotch, rhynchosporium, brown rust, ramularia and mildew in barley – with field trials clearly showing its ability to maintain a stronger flag leaf, which is crucial for maximising crop yield.”

Strobilurin

The third product is Maxentis, which sees prothioconazole in a mix with the strobilurin azoxystrobin.

Andy says the product is flexible in its application rate and timing, and is suitable for use with a wide array of partner products.

“It gives effective control of a range of foliar and ear diseases, including septoria, fusarium, rusts, ramularia, net blotch and powdery mildew in cereals, and sclerotinia and alternaria in oilseed rape.”

For the control of foliar diseases in wheat and triticale, Maxentis can be applied from GS30 (stem elongation) to GS69 (end of flowering).

In barley and rye, the product can be applied from GS30 to GS65 (mid-flowering).

For the control of fusarium on the ear of wheat, Andy says Maxmentis can be applied after ear emergence until the end of flowering (GS59 to GS69), with the optimum timing being early flowering (GS61 to GS63).

Finally, the fungicide is also registered for crown rust control on winter and spring oats.
