自己配制也行，就是洗碗液和油，不过我忘了比例了。
谢谢分享，我先去bunnings看看相应的白油吧。不过找到一个homemade配方，以后可以试下。
转贴如下：
This stuff is an essential in my vegetable garden which I try to grow where possible following organic principles. It kills scale, Aphids, white Fly and smooth skinned Caterpillars including those green Cabbage moth Caterpillars (my greatest enemy!!!!). It works by covering the insects breathing pores causing them to suffocate.
Ingredients
1 cup of vegetable oil
¼ cup Dish washing detergent
Place ingredients in a jar and shake well. You will notice it turns white; this is where it gets its name.
Things to remember
You need to be careful not to spray when the temperature is greater than 30.c or you risk burning your plants
It needs to be diluted!!!!! Use only 1 tablespoon per litre of water
Shake it well so it turns a milky colour before use (as shown in picture)
Label it so you can remeber what it is and when you made it.
White oil will store in the jar for about 3 months.
Hopefully you find it as useful as me!
