The broadacre fungicide market is filled with choices – single actives, combinations, and varying formulations. Here’s our list of fungicides options available for 2023.
Azoxystrobin aka Accolade/Mirador (Formulations 250g/L, 625g/L, 800g/kg)
Crops: Pulses, Canola & Cereals.
A group 11 fungicide, straight azoxy products now have broadacre crops registrations on the label. They can only be applied with an alternate MOA for resistance management, such as tebuconazole, propiconazole, prothioconazole or epoxiconazole.
Carbendazim aka Spin Flo (Formulations 500g/L, 900g/kg)
Crops: Chickpeas, lentils, faba beans.
Carbendazim is a go-to in pulse crops. It’s strong on Botrytis diseases in chickpeas, lentils and Chocolate Spot in faba beans.
A great feature about carbendazim is it has both protective and systemic activity. Carbendazim is also a member of the Group 1 benzimidazole fungicide group. And with no other members of this group available for use in pulse crops – it remains a valuable tool for resistance management.
Chlorothalonil aka Echo (Formulations 720g/L, 900g/kg)
Crops: All pulses
Chlorothalonil is a critical protective spray in all pulse crop spray programs. It’s a member of the multi-site activity group giving it a low risk of developing fungal disease resistance. Thus, chlorothalonil plays a crucial role in spray programs from a resistance management point of view. As a protectant fungicide, it must be applied before disease infection to achieve maximum control. And since it has no systemic activity, thorough spray coverage at the time of application is essential. It’s strong on Ascochyta diseases in Chickpeas, Lentils and Faba Beans.
Epoxiconazole aka Opus (Formulations, 125g/L, 500g/L, 800g/kg)
Crops: Wheat, barley (Soprano in oats and oaten hay).
Epoxiconazole is a great cost-effective option for cereals, with preventative, curative and eradicant control. Thorough coverage of the crop is necessary for best results. Used for rust in cereals, and strong on Septoria in wheat, as well as Stripe Rust in wheat. Also provides good protection from Powdery Mildew in wheat.
Note: Only Adama’s Soprano is registered for Septoria in Oats and Oaten Hay.
Mancozeb (Formulation 750g/kg)
Crops: Chickpeas, faba beans, lentils and Field Peas
Mancozeb is a protectant fungicide, and as the name suggests, it works by protecting crops from infection by fungal diseases. It is therefore essential that Mancozeb applications are made before infection occurs. Crops must be regularly monitored to detect any disease infection as early as possible to allow for timely application. Mancozeb is strong on Ascochyta and Rusts in Faba Beans, as well as Ascochyta in Lentils and Chickpeas where it will give good control. Mancozeb also give good protection from black spot in Field Peas.
