Kendon White Oil Insecticide 5L – Petroleum Spray Oil for Scale, Aphids & Mites

Kendon White Oil Insecticide 5L: Petroleum Spray Oil for Scale, Aphids and Mites

Kendon White Oil Insecticide is a petroleum-based spray oil for controlling scale and other sap-sucking insects on citrus, fruit trees, roses, ornamentals and indoor plants. It contains 825g/L petroleum oil and works physically rather than chemically: it coats the pests in a fine film of oil that blocks their breathing pores and suffocates them. That contact mode of action makes it a long-trusted, versatile tool for gardeners, and Kendon is an Australian-owned company that has been making it since 1950.

Because it kills by smothering rather than by a chemical toxin, white oil is effective on the soft-bodied and armoured pests that are otherwise hard to reach, including scale, aphids, mites, mealybugs and citrus leaf miner. It works well on the hard, waxy scale insects that shrug off many other sprays, and it also has a low poison profile: it is a Schedule 0 (unscheduled) product with just a one-day withholding period, so edible plants can be sprayed right up close to harvest.

The 5L size is a value pack for anyone with a number of citrus or fruit trees, a large rose garden or ongoing pest pressure, giving you plenty of concentrate to mix and spray across the seasons.

How to Use

White oil is a concentrate that you dilute with water and spray, and the correct dilution rate varies by pest and plant, so always mix according to the rate on the product label for your situation. Shake or stir to mix thoroughly, then spray to thoroughly wet the plant, covering both sides of the leaves, stems and the undersides where scale and mites hide, until just before run-off. Since it works by contact and smothering, complete coverage of the pest is essential. A repeat application is often needed to catch newly hatched pests.

Timing matters with oils. Spray in the cool of the early morning or evening, and avoid spraying in hot weather (generally over about 30°C) or on drought-stressed plants, as oil applied in heat can burn foliage. Do not spray plants that are sensitive to oil, and test on a small area first if unsure.

Safety and Responsible Use

• Read and follow the label. Mix at the labelled rate for your pest and plant, and observe the one-day withholding period on edible plants.

• Avoid heat and stress. Don't spray in hot conditions or on stressed plants, to prevent leaf burn.

• Check plant sensitivity. Some plants can be damaged by oil. The waxy blue coating on some conifers can also be removed by white oil.

• Protect yourself. Avoid contact with skin and eyes, wear suitable protection, and wash your hands after use.

• Dangerous goods shipping. As a petroleum product this item may need to ship by courier and can't go to a PO box.

Frequently Asked Questions

What is the mixing ratio for Kendon White Oil?
White oil is diluted with water, but the correct rate depends on the pest and plant, so follow the dilution table on the product label rather than a single fixed ratio. Mix thoroughly and spray to full coverage.

What pests does white oil control?
It controls scale, aphids, mites, mealybugs and citrus leaf miner, among others. It is especially useful on hard, waxy scale insects that resist other sprays.

What plants can I use it on?
Citrus, deciduous fruit trees, roses, ornamental shrubs, daphne and indoor plants, plus other listed crops. Avoid oil-sensitive plants, and note it can strip the blue bloom from some conifers.

Can I spray it on fruit and vegetables before harvest?
It has a one-day withholding period, so edible plants should not be picked for one day after spraying. Otherwise it can be used close to harvest.
