THE PROBLEM WITH BUGS!
Are you tired of the never ending battle with bugs? Spider mites, in particular, are the biggest problem to the indoor or hydroponic grower. It seems that once you have bugs, all you can do is keep spraying with one poison after another. As soon as you think you have them beat, they come back, again and again and control is the best you can hope for. Even predators are only effective for short periods of time and are very expensive with repeated use.
WHAT IS EINSTEIN OIL?
Einstein Oil is a unique formula whose main ingredient is a natural cold extracted oil from an Indian tree. This oil is 100% non-toxic and is the key ingredient in many herbal skin preparations, soaps and tooth pastes. It is also taken internally as a herbal remedy to treat a variety of health problems.
HOW DOES IT WORK?
Einstein Oil works by interfering with the insect's ability to molt. If a growing insect can not molt it will not reach sexual maturity and will therefore be unable to mate and reproduce. This means that within one to three life cycles, (10-40 days,) all the insects will die of old age and there will be no more eggs left to hatch. Einstein Oil will solve your bug problems once and for all!
A PLANT NUTRIENT AND GROWTH STIMULATOR
Einstein Oil is also a highly effective plant food and growth stimulator. Mix as per instructions and use as a foliar feed. Transplants will perk up immediately with a light spray. If you've had problems with red stems, dying tip ends, yellowing leaves or other nutritional problems, try a light foliar feed with Einstein Oil and watch the results.
Tests in USA on products with the same main active ingredient as Einstein Oil have shown efficacy against more than 250 species of parasites.
Einstein Oil is a natural herbal product which has proven to be harmless to humans and warm-blooded animals, fish and other marine organisms, birds and non-targeted, beneficial insects such as honey bees, spiders and so on.
Einstein Oil shows no genotoxicity, no teratogenicity, no reproduction alterations, no cancerogenicity and is fully biodegradable.
- this is the stuff we have been reading about,

- Here is some info on the Neem oil. THE STUFF WORKS but there is a down side. I only use it on young clones that will have at least 10 weeks before being harvested. The problem is its a systemic insecticide. It works by the plant absorbing the the active ingredients and as new mites try to suck on the plant they get some of the insecticide that the plant has absorbed. Similar to how the new flea repellents work for pets.
ok here it is
Rose Defense˘ - 3-in-1 Neem Product for More than Roses
by Mark Whitelaw
For centuries the people of Africa and Asia have known the benefits of the Azadirachta indica, the Neem Tree (also called the "Cornucopia Tree") ˇ its tropical foliage provides a beautiful ornamental look to the forest.
They have also known it has almost magical medicinal properties. In India, the locals have known if they chewed on the twigs of the Neem tree, mouth sores would disappear and they would have fewer cavities. The leaves could be crushed and rubbed on wounds for quicker healing. And mixing both leaves and twigs with stored grain would reduce pest infestation. [Persons] On New Year's Day, Hindus would eat the leaves of the Neem Tree or bathe in an oil-water mixture in hopes of remaining disease-free for the coming year. [Cairns] Today the Neem Tree is also grown in the Gulf Coast area and in the more temperate regions of the American hemisphere.
Refined from its leaves, stems and seeds, Neem oil is the primary product of this tree. Recent studies have identified no less than 26 constituents in Neem oil, but to date scientists are still baffled as to which properties do what and to whom!
As an insecticide, the principal active ingredient in Neem oil is Azadirachtin-A (or AZA), a teranortritepenoid and in the same family as those oils used in making fragrances. The commercial version of azadirachtin, called Azatin®, has tested effective against more than 170 different insect species, including beetles, flies, scales, aphids, mealybugs, white flies, termites, caterpillars, locust, crickets, spider mites, and root knot nematodes.
Sulfur, another ingredient that researchers believe is active, has been tested effective against fungi and molds. A study by H. E. Moline and J. C. Locke compared Neem seed oil with calcium chloride and fungicides for controlling post harvest apple decay. [Moline and Locke] In another report, Dr. William Quarles of the Bio-Integral Resource Center cited whole Neem oil as an effective fungicide against diseases common to roses. [Quarles]
This year, Green Light® has begun marketing a 3 in-1 pesticide for your roses and other landscape ornamentals. Called, Rose Defense˘, it is registered and rated effective against pest insects including spider mites, aphids and white flies, and rose fungal diseases like rust, powdery mildew, and black spot.
Rose Defense˘ is 90% clarified hydrophobic extract of Neem oil. The
balance is inert ingredients ˇ most commonly, these are surfactants and
emulsifiers. Apparently, according to the label, something else must be
in these ingredients as there is a cautionary note not to spray the product
when bees are actively visiting the treated area. (Neem oil, once dried on the leaves, is not normally harmful to bees.) The product is also very thick, and an advisory sticker reminds the user to shake well and bring the product to room temperature before mixing.
Unlike some Neem extract pesticides that require more product per gallon, Rose Defense˘ only requires one ounce (2 Tablespoons) per gallon of water to be effective. This makes the product more cost effective per application than previous Neem products. One pint of concentrate retails for about $15.
If sulfur, in fact, is the active fungicidal ingredient, its application
should probably be temperature restricted to 85°F (29ºC) and below.
Mode of action
Neem is virtually harmless to most beneficial insects such as bees, spiders, predatory mites, lady beetles, lacewings and wasps, and higher orders like us and our pets. [Olkowski] Some European studies have shown, however, that Neem can affect some species of beneficials by affecting their host.
The reason Neem is "selective" is twofold. First, it must be ingested by the insect to be effective. Most pest insects do just that ˇ chew on our plants! In most cases, beneficials prey only on pest insects, leaving our plants alone.
Secondly, Neem works as both a biodegradable contact and systemic botanical insecticide. Studies have shown that Azatin® drenched on the ground will be absorbed by the plant, while leaves that are sprayed will not absorb the chemical ˝ it just sits there waiting to get eaten.
When ingested by the pest insect, Azatin® works both as an antifeedant and prohibits molting. It does so by "antagonizing" the molting hormone, ecdysone, which permits the insect to develop from one molting stage to another. When the pest can't molt, it dies within 3 - 14 days.
Neem is virtually non-toxic to you and your pets, but of course caution should be used when applying any pesticide. It is highly biodegradable in sunlight and soil within a few weeks. Its oral LD50 (oral lethal toxicity) is greater than 13,000 mg/kg and it carries a Level IV Caution ("All Other") on the label. By comparison, chlorpyrifos (like Dursban®) has an LD50 of 163 mg/kg. And diazinon has an LD50 of 320 mg/kg. This makes Neem more than 40 times less toxic than the most common insecticides used for killing the same target pests. By comparison, common aspirin has an oral lethal toxicity of 1200 mg/kg.
This new product has the potential to solve a lot of common problems
among rosarians and is a welcomed addition to our arsenal of less toxic
controls. Look for it at your favorite nursery or home improvement center.
