Spring disease control in Oilseed Rape
Maintaining a healthy crop canopy in spring is essential for maximising green leaf area and light penetration as crops approach the critical flowering stage.
Problem diseases to watch out for in the spring...
Sclerotinia stem rot poses another spring risk, potentially leading to premature ripening, higher risk of lodging and associated yield losses.
• Infects plants at flowering.
• Causes premature ripening, lodging and yield loss.
Targeted fungicide applications during mid to late spring are essential for effective control of this damaging soil-borne disease.
Light leaf spot can continue to spread in the spring, often spreading from infections that began in the previous autumn.
Left untreated, it can severely impact leaves, stems, flowers and pods, causing significant yield losses.
• Carry-over from autumn infections.
• Affects leaves, stems, flowers and pods.
• Risk: High in mild, wet springs or where autumn sprays were missed.
Applying follow-up fungicide sprays in the early spring period provides an important last timing slot to control the disease or minimise further yield damage caused.
Other spring and early summer diseases, including Alternaria (dark leaf spot/pod spot) and Ringspot, may also need to be managed with appropriate fungicide choices.
• Alternaria affects pods, seeds and upper canopy. Can cause pod shatter and lower seed quality.
• Ringspot occurs less frequently but favoured by humid springs. Affects leaves and pods. Proactive assessment and early identification of crops at risk of disease are key to ensuring timely and effective applications to achieve the best results.

With a proven line-up including Clayton Navaro, Clayton Tuskar, Clayton Augusta, and Clayton Tebucon 250 EW, growers can rely on broad-spectrum triazoles and strobilurins that provide both systemic and protectant activity, ideal for use from stem elongation through to full flowering and pod fill.
Want to know more?
Products containing tebuconazole such as Clayton Navaro and Clayton Tebucon 250EW can be used effectively to manage forward crops to optimise the canopy for yield.
Whether you’re dealing with a forward crop, topping up after autumn sprays, or getting ready to protect during flowering, Clayton’s cost-effective range of spring fungicides give you the flexibility and reliable disease control you need.

Autumn disease control in Oilseed Rape
Establishing a healthy, well-structured canopy in autumn is essential for supporting root development, crop resilience and early disease protection in oilseed rape.
Problem diseases to watch out for in the autumn...
Phoma spray threshold: 10-20% plants infected (use lower threshold on more susceptible varieties and/ or where plants are small).
Image source ADAS
Light leaf spot should be prevented from developing early.
Good protection from subsequent disease development will be provided by a protective application of prothioconazole or tebuconazole in autumn/winter after GS20 (usually late October to early December).
Follow up spray(s) with an alternative product may be required in the spring from stem elongation, depending on disease development.
Phoma leaf spot/Stem canker can be found from October onwards and best control of stem canker may be expected from an autumn application (after GS 20) of prothioconazole or tebuconazole based products applied at the first sign of disease.
A repeat application of an alternative effective product in late autumn/winter may be required if symptoms reoccur.
For the best start, closely monitor crops for Phoma and Light leaf spot spray thresholds* in the autumn period and treat with broadspectrum protective and systemic fungicides (with either straight or coformulated product options) where required.
Disease management to control damaging diseases in the autumn is vital:
• Light Leaf Spot can lead to yield losses of up to 1.0 t/ha if left unchecked. Early prevention is key, as infection often begins in autumn but symptoms can be delayed.
• Phoma infection typical causes yield reductions of 0.5t/ha in susceptible varieties. Early leaf spotting is the first warning sign.
AHDB data shows average yield responses to a two-spray autumn fungicide programme at 0.3t/ha.
Light leaf spot threshold: As soon as infection is seen (to confirm disease, incubate leaves).
