White oil manufacturers charge a lot for what's so simple. Okay, I'll confess it up front; there's only one person who should be making this stuff that controls the sap sucking and chewing pests in your garden, and that's you.
Can you mix together cooking oil and washing up liquid, pour it into a two litre plastic container and give it a good shake? Then why would you want to approach a white oil manufacturer for their product that costs ten times as much? Do it yourself.
These blood suckers can cause havoc with your citrus trees, and roses, for example, spreading viruses that then attack your favourite plants.
I'll admit it up front; for three years I spent hours mechanically scraping white fly and aphids off the leaves of our citrus trees. Then an Australian cousin who was visiting told me about white oil.
Just one spray, taking five minutes per tree, removes 90 percent of the bugs by asphyxiating them, and a second a week later does the rest in.
My apologies, this isn't the greatest graphic. On the right is a five litre spray bottle, on the left a two litre plastic container, and in the foreground a measuring jug with 100ml of the white oil which I'm about to add to 5 litres of water; that's a 2% mixture.
Give a good shake, and away you go. Fill the spray bottle near to the top by the way.
It takes about five minutes per tree to spray against the sap suckers, depending on how old it is.
Although we are trying to wean off plastic, the root of many environmental evils, my old spray can has rusted through.
White oil manufacturers for making your own quite safe mixture that will control many of the bugs that attack your citrus and roses for example.
If you're a greenie like me, then you'll be reluctant to use toxic sprays to kill these aphids, and the like. Then you also destroy the ladybirds that feed on the sap suckers, and the little brown jobs that feast on all these tiny insects.
Just this afternoon I sprayed eight citrus trees. A not inconsiderable amount drifts onto you, and you inhale some of it too. Those toxic chemicals kill the bugs, but don't they affect our health too? White oil though is harmless.
When spraying with Roundup now, the only poison that keeps the weeds from around the pool, I wear the full regalia, including the gas mask for when using the sanding machine. They've admitted it causes cancer, albeit in large doses.
Okay, so here's the deal. Find a plastic two litre bottle. Pour in
Give it a good shake and, hey presto, you are a white oil manufacturer. It's not rocket science keeping these little menaces under control. Your mixture starves them of oxygen and they die a horrible death from asphyxiation. If that bothers you, give up gardening.
Make sure you spray both sides of the leaf, especially the lower where the white fly tends to congregate. The aphids prefer the stems of young leafy shoots.
Last year an unknown pest, I think a stink bug, attacked our pole beans leaving nasty black spots all over the fruit. This year I'm going to use our white oil on the young shoots and see if it helps. Growing green beans is a must for every gardener. Reduce your reliance on red meat for protein.
Here's an update; we then got hens and they sorted out the pests that were attacking our beans.
Then there are bean leaf beetles and a host of sap sucking bugs that attack both the leaves and the fruit. Asphyxiate them with your white oil.
It's highly concentrated, so dilute your white oil by adding 100 ml of the concentrate to five litres of water in a spray bottle; that's 2%. My cousin who is a citrus farmer recommends not going over 3 percent. Then spray it onto both sides of the leaves, and concentrating on the young shoots. Turn the nozzle upside down to spray upwards where most of the sap suckers will be found. Repeat in a week. You'll be stunned how successful it is on citrus. I have yet to try it on our green, snap beans.
Again, my cousin says not to spray more than twice a year; he's been using it for years, so I'm sure he's got good reasons for saying so.
This is what a lime leaf looked like before white oil.
And this, of course, is the appearance after white oil; the bugs are quite dead.
Notice how the parasites turn black and then peel off the leaf.
Update: It's now three months since I sprayed and there is not a sign of white fly.
It's now midsummer and I'm going to spray again soon; flowering is over and the new fruit set.
Update: It's now three years since we became one of the white oil manufacturers; I can mix together two parts + 1 part of two harmless liquids! It doesn't take a chem graduate or cordon bleu cook to do that!
What's interesting is that we have had much less of a problem of aphids on our broccoli, even though we never sprayed the broc; the citrus trees had become the breeding ground for many sap sucking bugs in our garden. We may even get to try brussel sprouts again.
Growing lemon trees is so easy. Dig a hole, fill it with compost and a bit of lime, and plant the young sapling; but you will need to be one of the white oil manufacturers.
And oranges, limes, mandarins and grapefruit too, but it's too cold here at nearly 4000' above sea level for the latter.
We enjoy a mixed citrus drink for most of the year, buying in when there is a glut on the market and keeping our own for when the commercial season is over. Your own white oil manufacturers is vital for oil of them. Aphids and other bugs will stifle the life out of them.
Growing lemon trees, so goes the old adage, should be your first move when you move into a new home; well, one anyway. I like a lime too; the flavour is rather different and the fruiting season doesn't entirely overlap.
If you want to do it properly, growing lemon trees is hard work, but it pays off with the tree bearing sooner, prolifically and for years. It means digging a hole one metre square, and another deep.
And without white oil manufacturers, the bugs spread viruses that will destroy your trees.
Lime nutrition is a wonder protecting us from cancers, gum disease, nerve dysfunction and promotes healing of tissues, such as after a slipped disc or sprained ankle. Limonin is the substance that is unique in citrus, giving it the sour taste, and of course vitamin C is important in many enzyme reactions in the body. None of it can happen, though, without your white oil manufacturers.
If only for their bioflavonoids that mop up the free radicals that destroy our DNA causing cancer, lime nutrition is a wonder. Not a day in your life should pass when you don't have at least a couple teaspoonfuls of fresh citrus juice, and the pulp too.
Don't use your white oil whilst the citrus is flowering; whether the bees don't like the smell, or the flower is covered in oil making fertilization more difficult, it makes no difference; it will affect the yield.
I sprayed these aphids yesterday, 23 January, 2017. I'll take another photo in a few days. It took 8 litres of the diluted mixture to spray 11 citrus trees, two quite small. Our citrus fruit list is quite extensive for a suburban home garden.
The aphids, arrowed, are quite dead, asphyxiated by the white oil; I scrape them off with my thumb; it may need to be repeated in a week or two.
Bernard Preston is a semi-retired chiropractor, passionate about not the cure, but the prevention of cancer. With 11 citrus trees in the garden attacked by aphids, the development of this white oil manufacturers page became vital.
Helen and he starting growing lemon trees the moment they built their home in the Midlands of South Africa. Now they have many citrus fruit bar grapefruit which really needs a hotter climate.
Lime nutrition only became a passion after he was introduced to them by his Dominican Republic brother; what a wonderful fruit.
I mentioned above that I was going to try this white oil on our green beans; that have been seriously attacked by the Mexican bean beetle. However it's not going to be necessary; since acquiring and allowing our free range hens to wander in the veggie garden for a couple hours every day, under supervision or they destroy the seedlings, we have little further problem with that bug. In fact I think the white fly is much less of a problem too.
I call it the synergy of green living; you let some hens loose that you've acquired for cage free eggs and, hey presto, you have much less of a problem from cutworm larvae and other beetles and bugs. Your kids will love this story in pictures of what do tadpoles eat. It's all part of what's known as backyard permaculture; working with nature instead of against it.
