The broadacre fungicide market is filled with choices – single actives, combinations, and varying formulations. Here’s our list of fungicides options available for 2023.

Straight Actives: 

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.

 

Procymidone aka Sumislex (Formulations: 500g/L, 800g/kg)

Crops: Canola, lentils, faba beans.

Procymidone is a highly effective protectant and curative fungicide for foliar application in a wide range of crops such as Canola, Lentils, & Faba Beans. It is a group 2 fungicide, which is a member of the discarboximide group of fungicides. Strongest on Botrytis Grey Mould in lentils and chocolate spot in Faba Beans. Procymidone also provides protection from Sclerotina rot (white mould).

 

Propiconazole aka Throttle/Bumper (Formulations 500g/L, 550g/L, 625g/L)

Crops: Barley, oats, wheat

Propiconazole is registered on a broad range of diseases in wheat, barley and oats and is effective on rusts, including stem rust and stubble-borne diseases. One of the key strengths of propiconazole is that it provides a high level of control of Yellow Spot in wheat. In barley, propiconazole has strengths on diseases such as Net Blotch, Scald and Powdery Mildew.

 

Prothioconazole NEW (Formulations 250g/L, 800g/kg)

Crops: Cereals, oats, canola

Prothioconazole is a group 3 DMI (Demethylation Inhibitor) fungicide that works by inhibiting the development of a specific enzyme in fungi. It boasts broad-spectrum control of many key foliar diseases. Depending on the situation, prothioconazole, such as Proviso, can be applied in rotation or tank mixtures with recommended fungicides with different modes of action to reduce the risk of resistance development. 

Ideal for use on cereals, oats and canola. Will control Blackleg, Leaf Rust, Net Form of Net Blotch, Powdery Mildew, Scald, Sclerotinia, Septoria Nodorum Blotch, Septoria Tritici Blotch, Spot Form Net Bloch, Stem Rust, and Stripe Rust. A great option for growers wanting to customise their foliar disease program.

 

Tebuconazole aka Folicur (Formulations 430g/L, 800g/kg)

Crops: Barley, faba beans, oats, wheat

Tebuconazole is a systemic fungicide with post-infection activity and up to three weeks of residual control. One of the major benefits of Tebuconazole is that it is registered on a wide range of diseases in wheat, barley, faba beans and oats. It is one of the most widely used fungicides in low-to-medium yielding wheat crops. It’s cost-effective and has greater efficacy and longer residual activity on key diseases such as Stripe Rust compared to alternatives such as propiconazole. Tebuconazole is also strong on rust and cercospora early in Faba Beans.
