Insects: ADG has conducted studies on green peach aphid, European asparagus aphid, European red mite, asparagus beetle, beet leafhopper, grape leafhopper, cabbage looper, diamondback moth, codling moth, Colorado potato beetle, corn earworm, peach twig borer, potato tuber worm, potato psyllid, onion thrips, rosy apple aphid, San Jose Scale, seed corn maggot, western flower thrips, two-spotted spider mite, wooly apple aphid, wireworm and symphylans, and others.  ADG also can monitor for beneficial organisms including ladybugs, big-eyed bugs, spiders, parasitic wasps, and lacewings.
Weed Control: ADG has conducted studies with most of the pre-emergence and post-emergence herbicides used in the Columbia Basin, as well as with cultural controls and herbicides approved for organic production.  We have access to a wide array of weed species.

Diseases and Nematodes: The farm has two acres with developed infestations of Sclerotinia, which enables us to conduct studies on white mold of potatoes, alfalfa, canola, peas and beans.  Potato diseases studied include early blight, Rhizoctonia and Verticillium.  ADG has also conducted studies on corn smut, hop downy mildew, grape, apple, cherry, and peach powdery mildew, grape bunch rot and other diseases.  We can inoculate plants or infest soil to ensure sufficient incidence and severity of fungal diseases such as onion botrytis.    ADG has conducted studies on the nematodes Meloidogyne hapla, M. chitwoodi, and Pratylenchus penetrans on resident populations at the research station.  Specific areas of the farm have been identified where these nematodes are widespread which ensures that the pest is present when efficacy tests are run.

Pesticide application methods include airblast, seed treatments, in-furrow treatments, boom sprayer, backpack sprayer, and chemigation. 
In 2013, we will carry out RCBD, replicated aerial  and chemigation efficacy trials.Temperature controlled chambers for post-harvest studies.
Insect cages for indoor and field use.
Potter spray tower for laboratory assays.
Year-round greenhouse space.
Multi-crop trial site: apple, pear, peach, raspberry, cherry, grape, hazelnut, in a replicated design, for phytotoxicity or yield studies.
Commercial scale potato sorting line to conduct yield and grade analyses.
28 varieties of grapes replicated 5 times; perfect for phytotoxicity studies.
