What is Pyrethrum Concentrate made from?
Pyrethrum Concentrate is derived from chrysanthemum-type flowers and contains natural pyrethrins. It’s often used in organic gardening, but organic certification depends on the exact formulation—check the label and your certifier’s rules.
What pests does Pyrethrum Concentrate control?
It works on contact to knock down soft-bodied insects like aphids, whitefly, mites, thrips, fungus gnats, ants, flies, mosquitoes, and more. It’s less effective on insect eggs and may require repeat sprays to catch hatchlings or hidden pests.
Where can I safely use Pyrethrum Concentrate?
It can be used indoors, outdoors, and in controlled grow spaces. Keep people, pets, and pollinators away during spraying and until dry. Avoid use near ponds or aquariums, and never apply directly to animals or bedding unless the label explicitly allows it.
How do I mix and apply Pyrethrum Concentrate?
It’s a concentrate and must be diluted. Common garden rates start around 10 mL per 1 L of water, but vary by plant and pest—always follow the product’s crop/pest table. Mix only what you’ll use and shake before each application.
How often should I spray Pyrethrum Concentrate?
For active pests, weekly applications are common. Spray early morning or late afternoon for best results. Always spray leaf undersides and aim for full coverage—don’t just mist the top.
Will Pyrethrum Concentrate burn my plants?
It can if over-concentrated, sprayed in direct sun, or applied to sensitive plants. Test on a small area first, avoid midday heat, and use the correct dilution rate to reduce risk of damage.
Do I need protective gear when using Pyrethrum Concentrate?
Yes—at minimum, wear gloves. Eye protection and a mask are recommended, especially for indoor or large applications. If it contacts skin or eyes, rinse immediately with plenty of water and seek medical advice if needed.
Can I mix Pyrethrum Concentrate with other sprays?
Some combinations (like oils or sulphur) can cause burn or reduce effectiveness. Do a small jar test first, and always patch-test on plants. Rotate pest control methods to reduce resistance issues—don’t rely on one product forever.
How should I store Pyrethrum Concentrate?
Store it sealed, in a cool, dry place away from direct sun and out of reach of children or pets. Use mixed spray the same day, as potency can degrade over time. Check the label for expiry info if the bottle is old.
How much spray does each bottle make?
A 250 mL bottle makes up to 25 L at 10 mL per litre. A 1 L bottle can yield up to 100 L. Choose based on your garden size and frequency of use—larger bottles suit ongoing pest management across multiple zones.
Why didn’t Pyrethrum Concentrate work the first time?
Common issues include missed coverage (especially leaf undersides), poor timing, or pest eggs hatching later. It’s not a one-spray fix—repeat applications and proper targeting are key for effective control.
