NEEM OIL
Controls both fungal and bacterial infections


Over the last few years we have talked about how great neem oil is as an insecticide and mitacide, but we don't want to forget the many fungal and bacterial problems neem oil can also solve.

Neem oil is pressed from the fruits and seeds of Neem (Azadirachta indica), an evergreen tree which is native to India, and is used as a broad spectrum insecticide, miticide, and fungicide, which is used on vegetables, fruit trees, ornamentals, and more.

It is used commonly as an effective fungicide for the prevention and control of various fungal diseases including:

  • powdery mildew
  • black spot
  • mildew and scab
  • anthracnose
  • rust
  • leaf spot
  • botrytis
  • needle rust
  • tip blight
  • alternaria
It also controls bacterial diseases such as fire blight.

As a preventative: neem oil should be applied on a 7 to 14 day schedule until the potential for disease development is no longer present.

To control disease already present: apply neem oil on a 7 day schedule until disease pressure is eliminated. Then continue spraying on a 14 day schedule to prevent the disease from reoccurring.

Directions for Use:
Mix at the rate of 2 tablespoons (30 ml) per gallon (3.8 l) of water. Thoroughly mix solution and spray all plant surfaces, including the undersides of the leaves, until completely wet. Frequently shake the solution as you spray to keep it mixed.
