Dear List members,
This is an excerpt from a recent press release by the worm casting
company. I have more detailed reports if anyone is interested.
Insect Repellency: Testing by California Vermiculture has shown that
specific production methods can give worm castings the ability to
provide insect repellency. WORMGOLD® has been shown to stimulate the
organisms (chitinase enzyme producers) in plants that work as a natural
repellants for a large array of insects. The repellants increase to a
level that the insects find distasteful. The insects then leave. The
effectiveness has been seen for aphids, white fly, and other bugs that
feed on the plant juices. Plants tested include: begonias, various
citrus, hibiscus, various houseplants, morning glory, roses, solanum,
and zylosma. The number of successful applications now exceeds 10,000.
Ten nursery managers have independently confirmed the insect repellency
effect of WORMGOLD®.
Independent testing at Quail Botanical Gardens in Encinitas, CA, has
shown very strong indication that the repellency is effective for bark
boring beetles such as ipps and ambrosia beetles. Seven various pine
trees with severe infestations were shown to be free of these beetles
within three months of a three part treatment using WORMGOLD®. These
trees continue to be free of the boring beetles after six months. The
effect will continue to be monitored under academic protocol for at
least 24 months. Boring beetles are a dominant cause of death of trees
around the world. This research will be published in academic
Since WORMGOLD® has shown effective repellency for a large array of
plants, it was a natural extension to test for repellency of the glassy
wing sharp shooter passing the dreaded Pierce’s disease in the vineyard
industry. Previous testing with several organic materials with worm
castings has shown positive effects for suppression of this plant
problem. California Vermiculture is presently conducting an extensive
field test of this three-part application in the vineyards in Temecula.
This work is being done in accordance with academic standards for
One element required for effective repellency of the root knot and root
lesion nematodes is in abundant supply in WORMGOLD®. Conceptually, this
would be effective at solving the harmful nematode problem seen in the
production of strawberries, tomatoes, and other crops where Methyl
Bromide has been used as a nematode fumigating gas. Methyl Bromide is
highly toxic and was scheduled for elimination from the marketplace in
January 2000. A five year delay was given to find a solution to the
problem. Our nematode research project is showing excellent progress.
The research by Dr. Elaine Ingham on the same application came to light
showing conclusive proof that worm castings can be used as an effective
means to solve the harmful nematode problem and also improve plant
health and production.
California Vermiculture has a patent application is in process as well
as an EPA bio-pesticide registration. Also EPA applications are
in-process for the fungus control and nematode applications.
