UK launch for new fungicide co-formulations

Three new fungicide co-formulations have been launched – giving growers more options against cereal diseases.

All three Adama products contain the active ingredient prothioconazole. Two incorporate the company’s Asorbital formulation technology to provide rainfastness and faster protection against key cereal and oilseed rape diseases.

The first of the three new products is Maganic. It contains a combination of prothioconazole (175g/litre) and difenoconazole (125g/litre) in an emulsifiable concentrate (EC) formulation, says Adama.

Strong protection

Manganic provides strong protection against a range of wheat, barley, rye, triticale and oilseed rape diseases, and is the ideal tebuconazole-free option for the T3 timing in wheat, says Adama fungicide specialist Andy Bailey.

The second new product is Avastel. It provides protection against a broad spectrum of foliar and stem base diseases thanks to a combination of prothioconazole (150g/litre) and fluxapyroxad (75g/litre).

Also manufactured using Asorbital technology, Avastel boasts a flexible label in terms of which cops it can be applied to and when. In wheat, for example, it can be applied at T1, T2 or T3, and in barley at T1 or T2.

Giving broad spectrum control of key foliar and stem base diseases in wheat, Avastal is and is also effective against brown rust, yellow rust and tan spot. In barley, it protects against net blotch, rhynchosporium, brown rust, ramularia and mildew.

‘Great value’

The third new product is Maxentis. It is marketed as a great value disease control fungicide thanks to its mix of two broad spectrum active ingredients: azoxystrobin (200g/litre) and prothioconazole (150g/litre).

Maxentis 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 fusarium on the ear of wheat, Maxentis can be applied after ear emergence until the end of flowering, says Mr Bailey. The optimum timing being early flowering, he adds.
