"Easily the most effective home garden product for mealy bug and scale."

Gardenadvice.co.nz review

Groventive controls a long list of nasties that suck and chew our indoor and outdoor plants, including aphids, mealybugs, scale, mites, leafhoppers, thrips, whitefly, psyllids  and more. It gives me the creepy crawlies just writing that list, eww. This is the 500ml concentrate which makes 50 litres of spray treatment. Measuring cup included.

Also available in 200ml size >

What is Groventive?

Groventive is a new generation systemic. It controls sucking and chewing insects on house plants, ornamentals, hedging and roses, while being low-toxicity making it safer for bees and beneficial insects. If you're on the hunt for the old Yates Confidor (no longer available to the hobbyist), Groventive is what you want instead. 

How does Groventive work?

Groventive is a systemic insecticide which works differently to a contact insecticide. Systemic insecticides don't have to come in contact with the insect. Instead Groventive is absorbed through the leaf, into the sap of the plant. When an insect tries to suck the sap or chew a part of the plant, they get a dose of insecticide. That means you no longer have to completely saturate every nook and cranny like a mineral oil spray and other contact insecticides, plus you'll use less and need fewer treatments. 

Yes, if you're comparing it to a contact insecticide, Groventive does cost more, however with Groventive you normally require only one application, occasionally two, to control even difficult to eradicate pests like scale and mealybugs. Other options like mineral oil sprays need excellent coverage to come in contact with all insects, and multiple applications.

What plants is Groventive for?

Potted plants (indoors and out), ornamentals (that's the category our houseplants are in), roses, flowers and hedging (note only for use on these plants listed).

What insects does Groventive treat?

Groventive treats aphids, mealybugs, scale, thrips, mites, leafhoppers, psyllids, spittlebugs and whiteflies.

How do you apply Groventive?

DOSE 

Use 10mls Groventive per 1 litre water

Groventive comes with measuring cup marked with 5ml, 10ml and 15ml increments to make measuring easy. Best used before pests get to high numbers, when they first appear or when you first notice pest damage.

DIRECTIONS 

Add all the Groventive and half the final water volume to a spray bottle. Mix well, then add the rest of the water. For best results, also add Enspray 99 which improves coverage and stays on foliage longer (recommended for both indoor and outdoor, but especially outdoor in case it rains following treatment). Spray the plant  thoroughly, concentrating on the foliage.  

TIPS

Keep the infested plant isolated away from other plants for at least 28 days. A single application may be all that's required, however keep an eye on the plant and reapply at 14 day and 28 day intervals if needed. Groventive is a systemic insecticide, not a contact insecticide, so won't kill pests instantly on contact. Two applications recommended for best results even if no signs of pests continue.

Safety first

Follow best practice when handling or applying this product. The same general safety precautions apply as for any spray treatment, including insecticides and fungicides, even those certified organic or generally safe.

Always check the label before use. Spray outdoors when possible, or in a well-ventilated area. Wear basic protective gear, including gloves and eye protection, when preparing and using the product. A coverall (like disposable Painter’s overalls) is recommended to protect clothing and reduce skin exposure. Avoid inhaling spray / mist. Avoid contact with eyes / skin. Wash hands and exposed skin with soap and water after use. Read the full safety precautions here before use >
