As winter slowly begins to set in, now’s the perfect time to get ahead of disease pressure and set your crops up for a healthy, productive season ahead. That’s where 7 Worlds Bordeaux WG comes in, your go-to copper-based fungicide for a thorough and effective winter clean-up spray.
Why Winter Clean-Up Sprays Matter
In crops like almonds, stone fruit, and grapes, there’s often a long gap between pre- and post-harvest fungicide applications. During this downtime, pathogens and bacteria can build up, increasing the risk of early infections and higher disease pressure in the season ahead.
That’s where winter clean-up sprays come in, giving growers a proactive strategy to stop disease before it takes hold. The most effective time to spray is during key growth stages:
- 25–50% leaf fall
- Again at 90–100% leaf fall
At these stages, the tree structure is fully exposed, allowing for deep coverage across trunks, twigs, and those hard-to-reach cracks and crevices where pathogens love to hide.
Why Choose Bordeaux WG from 7 Worlds Ag?
Traditionally, many growers have made their own Bordeaux mix using copper sulphate and lime, a time-consuming, messy, and potentially unsafe task. That’s exactly why we developed Bordeaux WG, to make your life easier.
This pre-made granular formulation features:
- Tri-basic copper sulphate – insoluble and ideal for protectant fungicide use
- Lime – enhances tenacity and sticking power
(Seriously… it sticks like glue!)
It’s safer, easier, and more effective. Some of the key benefits include:
- Active against both fungal and bacterial pathogens, including Pseudomonas and Xanthomonas
- Long-lasting protection, especially in winter and wet conditions
- Compatible with oils and wetters for even better coverage
- Blue colour for clear visibility during application
- Excellent sticking and weathering properties
- Registered on a wide range of crops
Bordeaux WG in Action
Winter clean-up sprays using Bordeaux WG are a key tool in your disease management toolbox. Applying it post-harvest helps destroy carry-over spores, reduce bacterial load, and significantly lower spring disease pressure.
It’s also the only time of year where full spray coverage is possible. For best results:
- Use higher than usual water rates
- Apply with compatible oils and wetters
- Spray past run-off to ensure deep penetration into bark crevices
