David Grays Malathion & White Oil Insecticide 200mL – Dual-Action Spray for Scale, Aphids & Mites

David Grays Malathion & White Oil Insecticide 200mL: Dual-Action Spray for Scale, Aphids & Mites

David Grays Malathion & White Oil is a dual-action insecticide concentrate that combines two proven pest controls in one easy-to-mix formula. It contains 100g/L maldison (malathion) together with 400g/L petroleum (white) oil, so you get the fast, broad-spectrum knock-down of malathion plus the smothering action of white oil in a single spray. It controls scale, aphids, thrips, caterpillars, leafhoppers and other insects, and is used on vegetables, fruit trees and ornamentals in the home garden.

Pairing the two actives is what makes this product so effective, especially on scale. White oil works physically, coating and smothering scale, mites and their eggs, while the maldison delivers a contact insecticide hit across a wide range of pests. Together they tackle both the hard, waxy pests that oils are good at and the softer, more mobile insects, which makes it a strong all-rounder for common garden infestations, particularly the scale that troubles citrus, roses and ornamentals.

Because it is a concentrate, you mix only what you need, which keeps it economical and flexible. As with any garden chemical, it should be used strictly as directed on the label, including the withholding period before harvesting any treated produce.

How to Use

Shake well, then mix the concentrate with water at the rate on the product label for your pest and plant, since rates vary with the situation. Spray to thoroughly wet the plant, covering both sides of the leaves, the stems and any visible scale, since both the oil and the insecticide need good contact to work. Apply late in the day, out of the heat, as oil-based sprays applied in hot conditions can burn foliage, and this also helps protect bees. Avoid spraying in high temperatures or on drought-stressed plants, and observe the withholding period on the label before harvesting treated fruit or vegetables. Always use as directed by the product label.

Safety and Responsible Use

• Read the label and keep out of reach of children. This is an organophosphate-based insecticide and must be used strictly as directed.

• Wear protective clothing, including gloves and eye protection, and avoid skin and eye contact and breathing the spray mist.

• Do not spray in high heat. As an oil-based spray, applying it in hot weather or on stressed plants can burn foliage.

• Observe the withholding period on the label before harvesting treated fruit and vegetables.

• Protect bees. Spray late in the day when bees are less active, and avoid spraying flowers that bees are visiting.

• Protect waterways. Do not let the product or spray enter drains, sewers, streams or ponds.

• First aid / poisons. In case of poisoning, contact the Poisons Information Centre on 13 11 26 or a doctor.
