Neem oil is effective against an array of garden insect pests that attack medical marijuana plants. Mites, thrips, gnats, whiteflies and aphids are all soft-bodied insects that can be treated with neem.
The problem with most neem oil is a lack of purity due to the extraction process. High heat and abrasive chemicals used during extraction reduces the amount of the active ingredient, azadirachtin, found in neem. This, in turn, makes the neem oil ineffective for use as an insecticide. Einstein Oil is produced differently. The process of extraction used for Einstein Oil is a cold water extraction. This process will take a little longer but will retain almost all of the neem oil’s azadirachtin content.
The higher percentage of azadirachtin found in Einstein Oil will battle bugs in a few different ways. It works as an anti-feed and the insects will choose to go elsewhere for their lunch. Einstein Oil is also a growth regulator. Any insect that eats or absorbs Einstein Oil cannot molt. If an insect is unable to molt into the next stage of its lifecycle it simply dies out. Additionally, insects seem to sense the presence of Einstien Oil and will not lay their eggs on treated plants.
The scientists who created Einstien Oil understood that a plant with an insect problem is going through stress. That is why they enhanced the formula with several other potent herbal ingredients in order to reduce stress caused by insects and help keep your medical marijuana plants healthy and green.
The dosage for Einstein Oil differs greatly depending on the plant variety. I generally start with 2 teaspoons per gallon and will increase it up to 2 tablespoons per gallon on certain varieties. Like any foliar treatment it, is always advised to test a small portion of the plants before spraying the whole crop.
