Biorationals: Ecological Pest Management Database

Pest Category (Select one) Pest Name (Select one)	Pesticide Trade Name - OR - Active Ingredients/Beneficial Organism

The database notes which materials are listed by OMRI (Organic Materials Review Institute). Because OMRI listings are frequently updated, organic growers should always check with their certifiers prior to applying any materials to their crops or livestock.

What are biorationals? Although there is no universally accepted definition, in the context of this database, "biorational" refers to pesticides in one of the following categories:
	microbial pesticides: formulations of viruses, bacteria, fungi, or nematodes that have low non-target impacts;
	pesticides derived from plants that have low non-target impacts and degrade into non-toxic components; and/or
	various new types of pesticides, such as particle film barriers, pheromones, and compounds such as Spinosad, that have low non-target impacts and degrade into non-toxic components.

How to use this database: There are four different drop-down menus.

If you want to search for materials to control a specific pest:

1. Pest Category -- Click on the "Pest Cateogry" drop-down menu. (This will populate the "Pest Name" field.)

2. Pest Name -- (Both common and scientific names are listed there.) Click on the "Pest Name" drop-down menu, then click on the "Search Treatment Options" button below the "Pest Name" menu. A listing of materials will be generated. A direct link to the label is available for most materials.

Additionally you can select either the Pesticide Trade Name or Active Ingredient/Beneficial Organism to refine your search. Then click on the "Search Treatment Options" button to receive further specific information.

3. Pesticide Trade Name -- Click on the "Pesticide Trade Name" to provide information specific to that material.

4. Active Ingredient/Beneficial Organism -- Click on the "Active Ingredient/Beneficial Organism" to provide a second list of all the other formulations in the database that contain that active ingredient or beneficial organism.

If you simply want information about a material/formulation, you have the option of searching in the right-hand drop down menus for either "Pesticide Trade Name" (the name the product is sold under), or "Active Ingredients/Beneficial Organism". You cannot do a search on both simultaneously.

To perform a new search, simply click on "Clear Fields" or click on the back arrow of your browser.

We are always interested in feedback. Any comments or suggestions should be sent to: Rex Dufour, NCAT Agriculture Specialist.
