Biological Fungicide
Bio-Trek 22G is the first biological fungicide approved by the EPA and is a strain of the beneficial
fungus Trichoderma harzianum. It is a granular product effective in reducing dollar spot,
pythium, and brown patch as well as enhancing root growth and increasing plant vigor.
Although Trichoderma is a very common organism found in nearly all soils in low levels,
the strain in this fungicide is more effective and formulated for maximum efficacy.
Colonization on roots and soil occurs rapidly after application. It is non-toxic to vertebrates
and plants and poses no potential for groundwater contamination.

Subject: BioTrek 22gYou list BioTrek 22G as manufactured by Wilbur Ellis. I think you will find that BioTrek 22G plus Rootshield and T-22 are manufactured by BioWorks, Inc. of Geneva, NY. The product, Tricodermia, is patented by Cornell University and manufactured by BioWorks, Inc and then is marketed by a number of distributors one of which is Wilbur Ellis. Wilbur Ellis does have exclusive on BioTrek 22G.
The Tricodermia has a broad range of uses. The potato marketplace is one of the best opportunities for growers to enhance their product at a reasonable cost and a safe product for human consumption. The entire vegetable industry will benefit from a product that improves quality and is safe for human consumption. The sugar beet and dry bean markets are needing help in this area also.

Whitefly Trap
An alternative to yellow sticky cards for whitefly monitoring has been developed by C. C.
Chu of the USDA. The problems with yellow sticky trap cards are they can be somewhat
difficult to work with and where populations are dense often get completely covered with
whiteflies very quickly, thus greatly reducing their efficacy. The prototype design was
based on theories and research of adult whitefly behavior. The trap is comprised of a
disposable, replaceable bottle at the top and a folded, washable yellow card at the bottom.
Field tests have shown them to be quite effective even though they contain no bait or sticky
substance. Mass production is expected to take place soon.
For more information contact Chu at USDA-ARS, Desert Irrigation Research Station, 4151 Hwy. 86, Brawley, CA 92227.

Liquid Borate Registration in Canada
Tim-bor®, a water soluble borate salt, is the first pesticide registered in Canada for treating
wood to control carpenter ants, termites, and wood boring beetles, and also for use in
protecting wood against decay fungi. According to the product label, "application of
Tim-bor to control wood-destroying organisms must be part of an Integrated Pest
Management strategy”. It can be applied as a powder or foam, sprayed or painted as a
liquid solution; injected into wood and wall voids and other cavities as both a preventive
measure as well as for an existing infestation; and can also be used as a crack and crevice
treatment for silverfish, cockroaches, and ants in food handling areas.
For more information contact U.S. Borax, P.O. Box 8090, London, Ontario NG6 2B0 or your local supplier in Canada of commercial structural pesticides.

Canadian Registration of BTK
BTK Biological Insecticide is a new product containing Bacillus thuringiensis kurstaki
(BTK) introduced by Safer Ltd. for 1996. It is registered for use on vegetables, fruit and
shade trees, ornamentals, and evergreens for control of a variety of caterpillars, including
tent caterpillars, cabbageworm, and tomato hornworm. This is an important development
and good news for homeowners and others who are not registered pesticide applicators
because it had been almost two years since a Domestic product containing BTK was
available in Canada.

Biocontrol Organism Sprayer
A sprayer for dispersing beneficial insects and parasites, called the Bio-Sprayer, has been
recently developed in a joint venture between Smucker Mfg., Inc. of Harrisburg, Oregon,
Beneficial Insectary, Dr. Louis Tedders, retired USDA entomologist, and Walter Kropf.
Biocontrol agents such as Trichogramma wasps, green lacewings, and predatory mites can
be dispersed evenly, gently, and widely with the new equipment, greatly enhancing the
efficacy of utilizing beneficial insects for large-scale applications such as orchards,
vineyards, and field crops. Two models are currently available: a tractor-mounted three
point hitch model and a backpack unit. The equipment utilizes a low pressure application
technique which does not require a pressure regulator, and the result is a very high survival
rate of the beneficials.
For more information contact Dr. Tedders at (912) 956-6436, Rob Smucker at (800) 333-4503, or Sinthya Penn, Beneficial Insectary at (916) 472-3715.

IPMIS Update
The Integrated Pest Management Information System (IPMIS), a database website
developed and administered by BC Environment, was enhanced in September, 1995 with
the inclusion of a search engine that allows for searches within all documents in the
database in addition to the titles, abstracts, and built-in keywords. Previously, searches
would only look within the list of keywords assigned to each document.
Also recently, many complete documents and photographs have been added to the database, including over 100 out of print factsheets originally published by Agriculture Canada in addition to factsheets on forestry and wildlife pests, a pamphlet on native beneficial insects, and a complete guide for developing IPM plans for coastal landscapes. The library of color pictures includes pests, pest damage, and beneficial insects.
The URL for IPMIS is "http://pupux1.env.gov.bc.ca/~ipmis/ipmis.html".

British Columbia Pest Management Plans
As of 1996, service licensees in the Lower Mainland and Okanagan regions of B.C. are
required to submit IPM plans as a condition of receiving their public land endorsement on
their landscape service license, which is the process for registering pesticide applicators in
British Columbia, Canada. Licensees in the Vancouver Island region have been under this
requirement for the past three years.
This is part of the implementation of BC Environment’s mandate for all pesticide application licensees (both public and private) to follow an integrated approach for their pest management requirements. The purposes of the plans are to demonstrate how IPM program components (identification, monitoring, injury and action thresholds, treatments, evaluation) will be addressed; and also to develop prescriptions identifying the control and preventive strategies which will be employed for all sites and pest problems.
In an effort to assist licensees in developing their own plans, a model IPM plan for coastal landscapes was created by a committee of pest management experts from both the public and private sectors and is available on the IPMIS (go to "Search References by Title/Author" and enter "Heath" or "Search References by Keyword" and enter "guide").
