With both new prothioconazole-based options and a range of other fungicides, our product choice for early season disease control in OSR ensures good protection for crops in the spring and more choice for growers.

 

Spring fungicide range providing choice & flexibility

 

AZOFIN® PLUS

Effective, systemic and protectant strobilurin fungicide

SC formulation 250g azoxystrobin

Crops: Oilseed Rape

Use rate and timing: apply at 1.0 L/ha for a maximum of 2 treatments per crop at a minimum 21 day spray interval. Latest application 21 days before harvest. Use against Sclerotinia as a protectant during flowering (best results from an application timing GS60-GS65, from early to mid flowering). Use against Alternaria as a protectant at early pod formation (before first spots appear on the pods).

Target diseases (Spring): Dark Leaf and Pod Spot (Alternaria spp.) – control. Sclerotinia stem rot – moderate control

 

CLAYTON TEBUCON® 250EW

Reliable, adaptable systemic triazole fungicide

EW formulation 250g tebuconazole

Crops: Oilseed Rape

Use rate and timing: apply at 1.0 L/ha between growth stages BBCH 20 and BBCH 69. For Light leaf spot, if disease develops over winter (and no Autumn treatment used), apply 1.0 L/ha in early spring from onset of stem extension. Or application either pre- or post-flowering will generally control late development of light leaf spot on pods and leaves. For Alternaria spp., apply 1.0 L/ha at onset of disease when black spots first appear on pods. For Sclerotinia stem rot, 1.0 L/ha applied at early to full flower will give some reduction. For Ringspot, spring/summer applications made for light leaf spot control may also give some reduction.

Target diseases (Spring): Light leaf spot, Sclerotinia stem rot, Dark leaf spot/pod spot (Alternaria) and Ringspot.
