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

Kendon White Oil: A Horticultural Spray Oil for Soft-Bodied and Armoured Pests

Kendon All Seasons White Oil Insecticide is a petroleum-based horticultural spray oil containing 825g/L petroleum oil, used to control scale, aphids, mites, mealybugs and citrus leaf miner. It's mixed with water and sprayed onto citrus, deciduous fruit trees, roses, ornamental shrubs, daphne and indoor plants. Instead of a chemical toxin, this white oil insecticide works physically, coating pests in a thin film of oil that blocks their breathing pores. This 5L concentrate from Kendon, an Australian-owned company, suits gardeners with several fruit trees, large rose beds or ongoing pest pressure.

How White Oil Kills Insects

Insects breathe through tiny pores called spiracles along their bodies. When white oil spray coats them, it blocks these openings and the pests suffocate. Because it works by contact rather than as a nerve poison, it controls insects that have built up resistance to chemical sprays, and it's especially useful on scale insects, whose hard or waxy shells protect them from many other insecticide sprays. The oil also smothers mite and scale eggs that it covers. White oil has no lasting residue, so it only affects pests it touches at the time of spraying.

What Is White Oil Used For?

• Scale insects: red scale, white wax scale and other armoured and soft scales on citrus, bay trees, camellias and ornamentals
• Aphids: clusters on new growth of roses, citrus and fruit trees
• Mites and spider mites: fine webbing and speckled leaves on roses, ornamentals and indoor plants
• Mealybugs: white, cottony insects on indoor plants, succulents in pots and ornamental shrubs
• Citrus leaf miner: silvery trails in new citrus leaves
• Spreading agent: added to some other sprays to help them spread across leaves, where the other product's label allows

When to Spray White Oil

• Citrus: for citrus leaf miner, spray every 5 to 14 days while young flush growth is present. For scale, spray when pests appear and repeat about 4 weeks later. Avoid spraying citrus in late autumn and winter.
• Deciduous fruit trees and roses: spray in winter after pruning and before bud burst, or when pests appear in the growing season.
• Indoor plants and ornamentals: spray at the first sign of scale, mealybugs or mites, and repeat after about 4 weeks.

Always spray in the cool of the early morning or evening.

How to Use White Oil for Aphids and Scale

• Check the dilution table on the label for your plant and pest. Typical rates fall between about 10 and 20mL of white oil per litre of water.
• Add the white oil to water in your sprayer and shake well to mix.
• Spray to wet the whole plant, including both sides of the leaves, stems and leaf joints where scale and mites hide.
• Spray until just before run-off, as full contact is what kills the pest.
• Shake the sprayer often during use to keep the oil mixed.
• Repeat as directed to catch pests that hatch after the first spray.

What Plants Don't Like White Oil?

Some plants are sensitive to oil sprays. Test a small area first on ferns, succulents, young seedlings and anything you're unsure about, and check for damage after 2 to 3 days. White oil can strip the blue, waxy coating from blue conifers and some other silver-leaved plants. Never spray plants that are drought stressed, wilting, or in direct hot sun.

Weather and Spray Compatibility

Don't spray when shade temperatures reach 30°C or higher, as oil on hot leaves can burn them. Don't mix white oil with sulphur sprays, neem oil or other oil-based products unless a label confirms they're compatible, and allow at least 2 weeks between a sulphur spray and an oil spray.

Frequently Asked Questions

What is the mixing ratio for Kendon All Seasons White Oil?

It depends on the plant and pest. Typical rates are about 10 to 20mL of white oil per litre of water. Use the dilution table on the Kendon label for your exact situation.

Can Kendon White Oil be used on citrus trees?

Yes. It controls citrus leaf miner, red scale, white wax scale and other scales on citrus. For leaf miner, spray every 5 to 14 days during new flush growth, and avoid spraying citrus in late autumn and winter.

Does white oil kill aphids?

Yes. White oil smothers aphids on contact. Spray the colonies directly, including the undersides of leaves and the tips of new growth, and repeat if new aphids appear.

What plants don't like white oil?

Ferns, succulents, young seedlings and some sensitive varieties can be damaged. White oil also removes the blue bloom from blue conifers. Test a small area first and never spray stressed plants or in hot weather.

Is white oil a good insecticide spray for plants?

White oil is a useful insecticide spray for sap-sucking pests like scale, aphids, mites and mealybugs, because it kills by contact and pests don't build resistance to it. It doesn't control chewing pests like caterpillars or beetles, which need a different product.

What is the best insecticide in Australia?

There's no single best insecticide for every pest. Match the product to the pest and plant: spray oils like white oil for scale, aphids and mites, and a registered caterpillar or beetle spray for chewing insects. Always choose a product registered by the APVMA for your use.

Can I spray fruit and vegetables before harvest?

White oil has a 1 day withholding period for edible produce, so wait one day after spraying before picking. Check the label for the crops it's registered on.
