SB Plant Invigorator & Bug Killer Concentrate — 3-in-1 Physical Pest Control & Foliar Feed
Best for: Growers wanting effective pest and mildew control without chemicals, toxins, or harvest delays
Our thoughts
This is one of those products that does what it says without the baggage. Physical action means no resistance build-up, safe around beneficial insects, and you can pick straight after spraying. One we sell a lot of for growers tired of hitting the same pests with the same chemicals week after week.
SB Plant Invigorator is a biodegradable, non-toxic concentrate that works as a triple-action solution: natural insecticide, mildewcide, and foliar nutrient feed all in one bottle. Unlike chemical or biological alternatives, it uses a physical mode of action based on plant-safe surfactants that penetrate pest defences and control a broad spectrum of common indoor and greenhouse pests without creating resistance. No harvest interval, no bird or bee damage, no complicated mixing — just spray weekly and move on.
How it compares
SB Invigorator sits in a different lane from most alternatives.
-
vs Neem oil: Physical action instead of chemical — no resistance risk, but requires weekly applications
-
vs Pyrethrin-based sprays: Bee-safe and bird-safe, where pyrethrin is toxic to beneficial insects
-
vs Spinosad: Faster contact kill, no harvest delay, works on a wider pest range including scale and mealybug
-
vs systemic chemicals: No toxicity concerns, no residue, safe for organic operations
The real advantage: pests can't build resistance because it's not a chemical they adapt to — it's a physical smothering action they can't evolve against.
Usage guidance
Standard application
Dilute 10ml concentrate per 1 litre of water. Spray upper and lower leaf surfaces thoroughly once per week. Works best with consistent weekly treatment rather than ad-hoc spraying.
Heavy infestations
First spray removes the protective wax coating pests rely on. Apply a second spray 2 days later to finish the job. Growers report 95% pest elimination in a single application when done properly.
Indoor growing
Safe to use indoors provided plants have good airflow after spraying. No ventilation issues or chemical fumes to manage.
Harvest timing
No waiting. Pick or harvest immediately after spraying — there's no residual period.
With biological controls
If you're running predatory insects (ladybugs, parasitic wasps), apply SB Invigorator to uninfected areas only, or use it before introducing biologicals. Repeated applications will harm their population.

Who this is for
- Growers wanting to avoid chemical pesticides without sacrificing effectiveness
- Anyone running organic or pesticide-free operations
- Operators with biological pest control programmes who need a compatible intervention
- Indoor and greenhouse growers managing regular pest pressure
- Growers who've hit resistance issues with repeated chemical use
Particularly suited to setups where harvest safety, pest resistance prevention, and ecosystem impact matter.
Our take
This is a genuinely different approach to pest control. Because it works physically rather than chemically, you're not fighting a losing resistance battle — spray it again next month and it'll work just as well. Add in the harvest safety, the bee-friendly profile, and the triple-action (pest control, mildew, nutrition) and you've got a solid all-rounder that earns its shelf space.
Good time to buy while stock lasts. Does exactly what it should, week after week.
