Helps Garden Sprays Stay Effective Longer
Wally’s RainGard is designed to improve the performance of garden sprays by helping them spread evenly, stick to foliage, and resist being washed off by rain.
Once dry, RainGard forms a protective film over the leaf surface. This helps hold spray particles in place and slowly release them over time.
Made from Pine Resin
RainGard is made from a biodegradable terpenic polymer derived from pine resin. It is commonly used as a natural spray adjuvant to improve spray coverage, adhesion, and weather resistance.
Useful With Many Garden Sprays
RainGard can be used with many garden sprays, including:
- Copper sprays
- Neem products
- Sulphur sprays
- Herbicides
- Foliar fertilisers
- Systemic sprays
It is especially helpful during wet weather or when plants are likely to be watered soon after spraying.
Why This Product Is Different
Unlike standard spreaders and stickers, RainGard does more than improve coverage. It also helps rain-proof sprays for up to 14 days in average conditions.
This makes it a practical choice for gardeners who want better spray performance without constantly reapplying after rain, irrigation, or changing weather.
What to Expect
RainGard can help sprays stay on foliage longer and improve overall spray performance.
You may notice:
- Better spray coverage
- Less spray runoff
- Improved sticking to foliage
- Reduced need to re-spray after rain
- Better performance from systemic sprays and herbicides
Results will vary depending on weather, spray type, coverage, and application timing.
How It Works
RainGard acts as a spreader, sticker, rain-proofer, and chemical bridge.
It helps spread spray particles evenly over foliage, then forms a thin protective film as it dries. This film helps hold sprays in place and supports slow release over time.
For systemic sprays, RainGard can also help improve movement into the foliage.
