SB Plant Invigorator & Bug Killer 500ml - Triple-Action Pest and Feed Spray
Best for: growers wanting a ready-to-use, non-chemical spray that tackles pests, mildew and plant feeding in one go.
Our thoughts
SBPI has built a genuine reputation for doing three jobs with one bottle: knocking back common pests, keeping mildew down, and feeding the plant while it's at it. It works by physically suffocating pests rather than poisoning them, which means resistance isn't really a concern. Straightforward, professional-grade stuff.
SB Plant Invigorator (SBPI) is a triple-action ready-to-use spray combining pest control, mildew control and foliar feeding in a single formula. Its active substance is a low-concentration surfactant (10-20% sodium lauryl ether sulphate) that works by physical action, coating and blocking the breathing spiracles of soft-bodied pests rather than poisoning them chemically. Alongside this, the formula includes chelated iron, nitrogen and seaweed extract, which act as a foliar feed to strengthen general plant health and vigour.
How it compares
It sits apart from most single-purpose pest sprays.
- vs synthetic pyrethroid pesticides: works by physical suffocation rather than a chemical toxin, so pests can't build up resistance over repeated use
- vs neem oil sprays: no oily residue or strong odour, and it's sold ready-to-use rather than needing dilution
- vs plain foliar feeds: also treats pests and mildew in the same application, doing three jobs where a standard feed only does one
In plain terms: professional-grade performance at a more sensible cost than buying separate pest control and feed products.
Usage guidance
When to spray
Use at the first sign of pest activity, or as a routine preventative during veg and early flower.
Application
Spray until the foliage is visibly wet, covering both the top and underside of leaves where pests like aphids and whitefly tend to hide.
Timing
Avoid spraying in strong direct light or heat to reduce the risk of leaf scorch - early morning or evening is best.
Edible crops
SBPI's manufacturer states it doesn't require a set harvest interval on edible crops thanks to its physical mode of action, but always check the current product label before use.

Our take
Three jobs, one spray, no synthetic pesticide baggage - SBPI earns its reputation by actually doing what it says. The physical mode of action is the real selling point: pests can't adapt to it the way they can to chemical sprays.
Does exactly what it should, day in, day out. Worth keeping a bottle of this on hand for the moment aphids or mildew show up.
