PureCrop1
PureCrop1 Australia — The Original OMRI Listed Colloidal Nano-Tech Spray
PureCrop1 is the original plant-based colloidal nano-tech foliar spray developed by Ray Drysdale and manufactured by Disco Bay Inc. — 17 years of formulation work condensed into a single bottle that works as an insecticide, fungicide, and biostimulant in one. OMRI Listed for organic use and trusted by commercial operations from berry farms to vineyards across North America, PureCrop1 is the spray you can apply right up to the day of harvest, without residue, phytotoxicity, or withholding. The Grow Guys stocks the original Disco Bay Inc formula for Australian growers — not a rebranded knock-off.

The brand story
17 years in the making — from cancer research to crop protection
PureCrop1 started in 2008 when Ray Drysdale set out to solve a problem that had been bothering him for years — the toxic chemistry baked into modern food production. He tracked down two scientists who'd spent two decades working on colloidal micelle technology originally developed for cancer therapy and asked a simple question: could the same nano-scale delivery system be rearranged to protect crops instead of target tumours? The answer, after nearly a decade of reformulation work, was yes.
By 2017 the first commercial PureCrop1 formulation was ready. Corn and soybean oils rearranged into colloidal micelles at 1 to 4 nanometres — small enough to interact directly with the gut bacteria of sap-sucking insects and the cell walls of mould spores, but food-grade enough to carry zero withholding period. Physical-mode action rather than synthetic chemistry, which means vastly lower risk of resistance buildup and no carry-over into the harvested crop.
Today PureCrop1 is OMRI Listed and trusted by commercial operations from Driscoll's berry farms to organic vineyards — growers who need plant protection that performs without the residue trade-offs of conventional pesticides. A handful of rebranded knock-offs have turned up under other distributor names since 2017. The Grow Guys stocks the original Ray Drysdale formula manufactured by Disco Bay Inc — the same bottle commercial growers have trusted since day one.
What PureCrop1 supports in your grow
PureCrop1's micelle structure is sensitive to how you prep the mix. Always fill your sprayer with lukewarm water (around 25°C) first, then add the measured PureCrop1 — never the other way around. Pouring water onto concentrate can break the colloidal structure and kill the efficacy before you've even reached the canopy. Apply early morning or just after lights-off so the spray stays wet on the leaf longer — that's when the micelles do their work. Cover leaf undersides too, because that's where sap-suckers actually live.
Frequently asked questions
Is PureCrop1 available in Australia?
Yes. The Grow Guys stocks the full PureCrop1 range from 100mL to 4L, shipping Australia-wide from our Tasmania warehouse. Free shipping over $499*.
Is this the original PureCrop1 or a rebranded version?
Yes, this is the original formula developed by Ray Drysdale and manufactured by Disco Bay Inc — the same product commercial growers have trusted since 2017. A handful of rebranded knock-offs are circulating under other distributor names; this is not one of them. If you've used PureCrop1 before and trusted the results, this is the same bottle.
What makes PureCrop1 different from standard insecticides or fungicides?
Two things. First, it's plant-based — corn and soybean oil rearranged into colloidal micelles at 1 to 4 nanometres, not a synthetic chemistry. Second, it does three jobs from one bottle (insecticide, fungicide, biostimulant) with zero withholding period. Most growers end up replacing two or three separate products in their rotation.
Is PureCrop1 certified organic?
Yes — PureCrop1 is OMRI Listed for organic use, the US Organic Materials Review Institute certification recognised by USDA NOP. In Australia, OMRI Listed status doesn't automatically translate to ACO or NASAA certification (those are separate bodies), but OMRI is the most rigorous independent review of organic-compatible inputs globally. The ingredients themselves are food-grade corn and soybean oil derivatives.
