The Case for Durable, Rain-Fast Slug Pellets

August 28, 2025 Sarah Ferrie

Why De Sangosse Ferric Phosphate Leads the Field

Slug pressure is one of the most unpredictable and damaging threats to autumn crops. A single wet weekend can turn a lightly grazed crop into a write-off — and in many seasons, the window for effective control is frustratingly narrow.

In such conditions, pellet durability is everything. The more time a pellet remains intact and palatable in the field, the longer it provides control without the need for costly reapplications.

Why Rain-Fastness Matters

Slug pellets don’t just have to kill slugs — they have to keep working through the weather that slugs love most: damp, cool, overcast days and nights.

Rain dissolves inferior pellets, washing away active ingredients and reducing palatability.
Breakdown in wet conditions means more gaps in protection, requiring extra passes and risking feeding damage between treatments.
Lost bait points leave young crops exposed just when they are most vulnerable.

For every day a pellet remains attractive and intact, you buy time — protecting your crop and reducing labour and machinery costs.

The De Sangosse Difference

Not all ferric phosphate pellets are equal. De Sangosse’s class-leading range is designed around a simple principle: maximum attractiveness and palatability, maximum persistence with optimal field coverage.

Key Advantages:

High-Quality Cereal Base, Attractant
- Uses premium durum wheat flour and proprietary colzactive attractant (extracted oils from brassica plants) for exceptional attractiveness to slugs.
Perfectly Matched Additive System
- Efficient 1:1 stoichiometric ratio ensures chelating agent : ferric phosphate is perfectly matched for faster release, better transport, and optimum slug kill.
Patented TDS Advanced Wet Process Precision Manufacturing
- Uniform pellet size ensures a consistently stronger and more durable pellet than alternative wheats and simpler manufacturing processes.
Class-Leading Durability
- Proven to withstand repeated wetting and drying cycles without crumbling.
Even Spreading Performance
- Strong, dust-free pellets spread evenly up to 32m for accurate coverage.
Built to Perform Without Compromise
- Trials demonstrate De Sangosse Ferric Phosphate delivers the fastest and most effective control of slugs on the market.

De Sangosse Ferric Phosphate Pellets: 10 Days Intact

The Rain-Fast Benchmark

Trials repeatedly show De Sangosse ferric phosphate pellets hold together longer under wet conditions than ferric alternatives.

10 days intact in simulated rainfall tests
Maintained attractiveness long after other pellets had degraded
Reduced need for repeat applications in wet autumns

Economic & Agronomic Benefits

Durability is more than convenience — it’s profit protection:

Fewer reapplications mean lower labour and machinery costs.
Extended protection through prolonged slug activity periods.
Consistent baiting points maximise kill rates and crop establishment.
Better return on investment from each pellet applied.

The Farmer Takeaway

When slug pressure is high and weather is against you, you need a pellet that won’t quit. De Sangosse’s ferric phosphate range offers:

Proven rain-fastness
Market-leading attractiveness
Reliable spreadability
Consistent performance season after season

In short: spend once, spread once, and protect your crop longer
