2012 Annual Report
Commercially acceptable minor crops were grown and sprayed according to the protocols with various test substances using small plot sprayers that simulate commercial application equipment. Crops were frequently monitored for phytotoxicity from application treatments and timing. Residue samples were collected at harvest and frozen until shipment to a designated laboratory for residue analysis.
Four of the FY12 trials were joint USA and Canadian studies on asparagus, basil and cane berries. These projects will establish international maximum residue level tolerances acceptable to US Environmental Protection Agency and the Organization for Economic Cooperation and Development. The purpose of these studies was to reduce or eliminate pesticides as a trade barrier for export of US produced specialty crops.
Herb projects were undertaken on chives, basil and rosemary for both fresh and dried samples. Two insecticides, Evergreen and Movento, were sprayed on chives to control various insect pests. Basil was tested with a new fungicide, DPX-QGU42, for control of downy mildew. The herbicide Treflan was applied on rosemary plants to help with weed control.
