🚚 Free UK shipping on orders over £50 🪴
SB Plant Invigorator Concentrate is an economical plant treatment that combines physical pest control, powdery mildew control and foliar nutrients in one versatile formula.
Suitable for houseplants, orchids, greenhouse plants and many edible and ornamental crops, the 250ml concentrate makes up to 25 litres of ready-to-use spray – ideal for larger plant collections or anyone treating plants regularly.
Controls Common Plant Pests
SB Plant Invigorator can be used to control a range of common plant pests, including:
- Aphids
- Whitefly
- Spider mites
- Mealybugs
- Scale insects
- Psyllids
It works through a physical mode of action rather than a conventional chemical or biological pesticide action, so pests cannot develop resistance to it.
Helps Control Powdery Mildew
SB Plant Invigorator also helps prevent and control powdery mildew, making it a useful all-round treatment for both pest and fungal problems.
Foliar Feed & Plant Wash
As well as controlling pests and mildew, SB Plant Invigorator provides foliar nutrients and acts as a plant wash, helping foliage stay clean and fresh-looking.
How to Dilute
Dilute 10ml of concentrate in 1 litre of water.
For best mixing, add the required amount of water to your sprayer first, then add the concentrate and agitate well. Always use diluted and do not exceed the recommended application rate.
How to Apply
- Shake the concentrate well before use.
- Dilute at 10ml per 1 litre of water.
- Spray the plant thoroughly, covering both the upper and lower leaf surfaces.
- For maximum effect, apply on a weekly basis.
Good coverage is important because SB Plant Invigorator works by making direct contact with the pests or mildew being treated.
