Three new fungicide co-formulations containing prothioconazole have been launched in the UK.

The first of the three new products, Maganic, contains prothioconazole (175g/l) and difenoconazole (125g/l) in an emulsifiable concentrate (EC) formulation.

Adama’s fungicide technical specialist, Andy Bailey, says Maganic provides strong protection against a range of wheat, barley, rye, triticale and oilseed rape diseases. “It’s an ideal tebuconazole-free option for T3 timing in wheat.

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

Patented system

According to Andy, Asorbital uses a patented solvent and adjuvant system to improve uptake of active ingredients into, and migration within, leaf tissue. “This novel technology not only provides faster protection against key pathogens but also helps to improve rainfastness, with trials showing that all Asorbital formulations are extremely safe when used on registered crops.”

The second new product, Avastel, provides protection against a broad spectrum of foliar and stem base diseases and contains prothioconazole (150g/l) and fluxapyroxad (75g/l).

Also manufactured using Asorbital technology, Avastel boasts a flexible label in terms application – in wheat it can be applied at T1, T2 or T3, and in barley at T1 or T2.

“Avastel combines two complimentary modes of action to deliver robust and long-lasting protection in wheat and barley as well as in rye and triticale,” highlights Andy.

“It demonstrates broad-spectrum control of key foliar and stem-based diseases in wheat and is also effective against brown rust, yellow rust and tan spot. It 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.”


Maxentis

The third and final new product is Maxentis which has two broad spectrum active ingredients: azoxystrobin (200g/l) and prothioconazole (150g/l).

Andy adds that Maxentis is very flexible in terms of its application rate and timing and is suitable for use with a wide array of partner products. “Its co-formulation of two broad spectrum fungicides 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 OSR.”

For the control of foliar diseases in wheat and triticale, Maxentis can be applied from BBCH30 to and including BBCH69. In barley and rye it can be applied from BBCH30 to and including BBCH65. Maxentis is also registered for crown rust control on winter and spring oats.

For the control of fusarium on the ear of wheat, MAXENTIS can be applied after ear emergence until the end of flowering with optimum timing being early flowering.

To control sclerotinia in OSR, the product can be used as a protectant spray at flowering, with the optimum application timing being at the mid-flowering stage. Whereas for the control of alternaria, Maxentis can be used as a protectant spray from full flowering to and including 30% of pods at their final size.
