Quick Answer Dual-action spray eliminating pathogens on contact, then forming a protective biofilm for up to two weeks. Targets powdery mildew, grey mould and bacterial leaf infections specifically. Best suited to stopping outbreaks fast, once mould or bacterial spread has already started. Ships fast from within Australia. Micro Kill Concentrate is a dual-action antimicrobial spray that eliminates fungal and bacterial pathogens on contact, then forms a protective biofilm over plant surfaces to prevent reinfection for up to two weeks. Powdery mildew, grey mould, and bacterial leaf infections are among the fastest ways to lose plant health and yield, and once established, they spread quickly across an entire crop. Micro Kill is formulated to stop outbreaks fast and keep them from coming back. Effective as both an emergency treatment and a preventative spray across indoor plants, hydroponics, coco coir, and soil. Key Benefits Destroys fungi, mould, and bacteria at the cellular level within 48 hours Forms a protective biofilm that blocks spore germination and pathogen reattachment for up to 2 weeks Reduces microbial load across plant surfaces and grow environments Protects leaf health and photosynthesis from disease-related disruption Dual-use: foliar disease treatment and grow space hygiene control How It Works Micro Kill penetrates microbial cell walls and disrupts the internal structures of pathogens, breaking down fungi, mould, and bacteria rapidly on contact. After the initial kill phase, it forms a thin biofilm layer over treated surfaces that prevents spore germination and blocks pathogen reattachment, extending protection well beyond a single application. This two-phase mechanism means you're not just treating the outbreak you can see, you're reducing the conditions that allow the next one to establish. It can also be used to lower overall microbial load in grow spaces, supporting crop hygiene across the full cycle. How to Use Dilute and apply as a foliar spray with full coverage, paying attention to undersides of leaves where pathogens establish first. Use at first signs of infection or apply preventatively during high-risk periods. Works across indoor plants, DWC, NFT, coco, and soil. Apply during low light or lights-off periods for maximum effectiveness and to reduce the risk of leaf stress. Micro Kill is a pathogen control system, not just a fungal spray. Use it to stop outbreaks fast and protect your plants long after the application dries. Frequently Asked Questions How do I add Micro Kill Concentrate to my feeding program? Add Micro Kill Concentrate to your nutrient solution after mixing your base nutrient. Always add additives to water rather than directly to concentrated nutrient solutions. Stir well after each addition and check EC and pH before use. Start at the lower end of the recommended dose range and increase progressively, additives are potent and more is not always better. Is Micro Kill Concentrate compatible with organic and mineral nutrient programs? Micro Kill Concentrate is compatible with most hydroponic nutrient programs including both mineral and organic-based systems. If running a fully organic or biological program, check the formulation, some mineral additives can inhibit beneficial microbial populations. When in doubt, contact us at [email protected] for compatibility advice specific to your setup. Can I use Micro Kill Concentrate in soil, coco, and hydro? Yes, Micro Kill Concentrate is suitable for use across all growing mediums including soil, coco coir, perlite, rockwool, and all recirculating and run-to-waste hydroponic systems. Dose rates may vary slightly between growing systems, always follow the manufacturer's feeding chart for your specific medium. Does Micro Kill Concentrate ship fast within Australia? Yes, Micro Kill Concentrate ships from within Australia with fast tracked delivery Australia-wide. Most orders to VIC, NSW, QLD, SA and ACT arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.
