Pairs well with
Broad Blue Protect Concentrate is the larger-volume, dilute-your-own version of the systemic pest control that handles broad mites, spider mites, and leaf-chewing insects in a single application. 250ml of concentrate makes 10 litres of finished spray — enough to cover multiple tents or a small commercial room through a full vegetative cycle. Same 8-week systemic protection as the RTU bottle, with roughly 13× the usable spray per bottle. Ornamental use only, 8-week withholding period — not for food crops.
Specifications
- Ornamental plants only. Not for food crops, herbs, vegetables, or anything you plan to consume. The 8-week withholding is non-negotiable.
- Stick to the dilution rate — 25ml per litre (125ml per 5L sprayer). Going stronger doesn't give more protection; it just raises burn risk and wastes product.
- Mix only what you need for one session. Diluted spray loses potency within 24 hours once it's off the concentrate bottle.
- Apply in week 2 of vegetative growth — enough foliage for proper uptake, well clear of any flowering window.
- Shake the concentrate bottle thoroughly before every pour. Actives can settle during storage.
- Spray lights-off, always. Hot leaves plus systemic spray equals leaf burn you didn't want.
- Rotate Broad Blue with different-action products (organic contact sprays, beneficials) across cycles — reduces the chance of resistance building up long-term.
- Wear gloves. Don't spray near fish tanks, ponds, or aquariums. It's a synthetic product, not a herbal one.
How to Mix & Apply
Pairs Well With
The pre-mixed version for smaller setups or anyone who doesn't want to mix. Concentrate for big rooms, RTU for single tents.
ZT 699ml AerosolOrganic contact spray for food crops and late-flower coverage where Broad Blue can't go. Different mode of action — smart rotation partner.
Insect Traps & MonitorsSticky traps flag pest pressure early — the sooner you spot broad mites, the easier the treatment window.
Full Pest Management RangeBuild a rotation program across different actives. Stacking one product indefinitely builds resistance — rotation keeps you ahead.
FAQ
What dilution rate should I use?
25ml of concentrate per 1 litre of water — or 125ml per 5L pump sprayer. Don't go stronger thinking it'll work better; over-concentration raises leaf burn risk without improving pest control. The dilution is calibrated to the systemic uptake rate.
Concentrate or RTU — which should I buy?
Concentrate wins on cost per litre of finished spray — roughly $8.50/L versus $44/L for the RTU. That's about a fifth the per-litre cost. Go concentrate if you're treating two or more tents, running a commercial setup, or want the option to mix only what you need. RTU wins on convenience: for a single home tent and no sprayer, just pull the trigger.
Can I use it on food crops, herbs, or vegetables?
No. Broad Blue Protect is registered for ornamental plants only and carries an 8-week withholding period. It's not cleared for food crops, herbs, fruit, or any plant you plan to consume. For edibles, use an organic contact spray with zero withholding — Zero Tolerance is the usual pick.
Does one spray really last 8 weeks?
Yes. Because the active is systemic, it translocates through the plant's vascular system and keeps working from the inside — including protecting new growth. That's the fundamental difference from contact sprays, which only protect the foliage wet at spray time.
How long does the concentrate keep once opened?
Around 12 months sealed and stored in a cool, dark place. Once diluted in water, use within 24 hours — the active degrades in solution. Mix what you need for one session, then rinse the sprayer before storing it empty.
Can I spray it during flowering?
No — apply in early vegetative growth (around week 2 of veg). The 8-week systemic window is designed to cover a full veg-to-flower cycle from a single early application. Spraying in flower risks residue at harvest and doesn't align with the withholding period.
What if I already have a bad mite or thrip infestation?
Broad Blue works on active pests too. Remove heavily infested leaves, bag and bin them, then apply. For severe cases, pair with an organic contact spray as the initial knockdown, then apply Broad Blue to lock in the 8-week protection window. Don't mix them in the same sprayer — use them in sequence, not combined.
Will pests build resistance if I use it every cycle?
Yes, eventually — any single-mode-of-action product will push resistance if you rely on it exclusively. Rotate Broad Blue with products that work differently (organic contact sprays, beneficial predators, different actives) across cycles to keep it effective long-term.
