White Oil, a Horticultural Oil is used for controlling sucking and chewing insects like aphids, scale, mealy bug and citrus leaf miner. It’s not a poison, but suffocates the pests – so they can’t develop a resistance. It needs to be sprayed on both sides of leaves and stems to work properly.
RECIPE
One cup dishwashing detergent
Two cups sunflower oil
Add to a clearly labelled jar or other container, close the lid tightly and shake until it becomes white – and presto! Concentrated White Oil.
When ready to use, dilute one tablespoon of the concentrate to one litre of water. Add to a clearly-labelled spray bottle, shake and off you go!
NOTE – please do not apply when the temperature is 30 degrees Celsius or over as it may burn your plants.

Thanks so much, my bamboo needed this, although I think it's a bit too hot in Canberra to do this right now! 🌱
Neat. A cheap alternative to neem
Thank you!
Fantastic. TY for info.
Wow very good alternative for pest control for outdoor gardening.My question is what is a good alternative for us indoors house plants if you have one? You said to use on Woody plants. Thanks for sharing
great video, but please add captions to your videos.
good Video, I want to subtitle this in my home language and publish it in a non profitable agriculture facebook page. Do you Agree ? thank you for the instructions.
Is dish detergent just dish soap?
Could the same gear be used on cucumber plants and capsicum and tomato plants?
Thank you for the great advice, Gardening Australia! 😀
Can I use any other kind of oil? Or does it have to be sunflower??
I sprayed my vegetable sprouts with this because I had aphids and the possums ate them straight after I sprayed them. Will the possums get sick?
Surely the detergent is harmful to the soil,unless its bio degradable .
Chad suffocant vs Virgin poison
would this work on thrips as well?
Hi! Does it have to be sunflower oil or can you use regular olive oil??
Can l use white mineral oil with soap
Can I spray this liquid oil on strawberry plant? ……..
I wouldn't say an insect could never evolve to exhibit a resistance to white oil.
Just a question of time
Can i pour the diluted mixture into the soil. Mealybugs also attack my fruit tree roots
