Frequently asked questions

What is white oil and what is it made from? 

White oil is a horticultural spray oil. This particular product, Kendon All Seasons White Oil Insecticide, has an active constituent of 825g/L petroleum oil, which makes it a refined mineral oil rather than a plant- or vegetable-based oil. 

It works physically, not chemically, coating soft-bodied insects and their eggs in a light film of oil that blocks their breathing pores and leads to suffocation and death. Because it works on contact, thorough coverage of both sides of the plant’s leaves and the stems is essential for best results. 

Does white oil treat citrus gall wasp?

No, this white oil spray cannot be used as a citrus gall wasp treatment. For citrus plants, the product label covers citrus leafminer and scale insects (red, white wax, and black scale) only, with no control or suppression claims for citrus gall wasp. 

This is because white oil works by smothering exposed soft-bodied insects on the leaf surface, whereas citrus gall wasp larvae develop inside woody galls within the stem where a contact oil spray cannot reach them.

Government horticulture guidance for citrus gall wasp centres on lifecycle measures like pruning out and destroying galls before the adults emerge.

What is the mixing rate of Kendon All Seasons White Oil Insecticide per litre of water? 

For scale, aphids, mites, and mealybugs on deciduous fruit trees, roses, indoor plants, and ornamental shrubs, and for scale on citrus, the mixing rate varies up to 20mL per 1L of water.

For citrus leafminer on citrus, the rate is 5mL to 10mL per 1L of water for commercial use and 2.5mL to 10mL per 1L of water for home gardens.

For daphne, it is 10mL per 1L of water.

Always follow the rate on the product label for your specific plant and pest. Pour the water first, then add the white oil and stir well. Keep the mixture agitated while spraying. 

When should white oil insecticide be sprayed?

The timing of when you spray white oil will depend on the plant and pest, as instructed on the product label.

On deciduous fruit trees and roses, spray in winter after pruning and before bud burst, or at other times when pests appear. 

On citrus, spray for citrus leafminer at intervals of 5 to 14 days while young flush growth is present, and spray for scale when pests appear. Avoid spraying citrus in late autumn. 

For indoor plants and ornamentals, spray when pests appear and repeat after 4 weeks.

In general, do not spray when the shade temperature is above 30°C or when plants are moisture-stressed. Do not pick edible plants for 1 day after spraying. 

Can white oil burn or kill plants?

Yes, white oil can damage some plants if misused. The product label for Kendon All Seasons White Oil Insecticide states that certain plants are sensitive to oil sprays and advises testing on a small sample first if in doubt. Other general directions for spraying this insecticide include: 

• Do not spray on walnut foliage
• Do not spray when the shade temperature exceeds 30°C
• Do not spray when plants are moisture-stressed
• Do not combine with carbaryl, lime sulphur, or other sulphur-based sprays to avoid injuring the plant
• Note that the oil can remove the blue bloom from some evergreens

White oil vs eco-oil vs neem: What’s the difference? 

Each of these three products is a contact spray insecticide that relies on thorough coverage and generally targets soft-bodied pests like scale, aphids, mites, and mealybugs. Where they differ is the composition of the oil.

White oil is based on refined petroleum (mineral) oil. Eco-oil is a botanical oil product made from plant-based oils rather than petroleum, and neem-based products are derived from the seeds of the neem tree and are therefore also plant-based.
