Progress Report Objectives (from AD-416): Objective 1: Develop chemical control measures for weeds in ornamental vegetables, fruits, and specialty crops. [NP 304, C2, PS 2B] Objective 2: Determine the response of crops to herbicides to support new pesticide registrations in minor acreage crops. [NP 304, C2, PS 2B] Approach (from AD-416): Herbicides, alone or in combination with other herbicides or with cultural and mechanical weed control methods, will be evaluated under field conditions to determine weed control and crop responses. The research conducted in this project is part of the national effort of ARS to generate information supporting the registration of minor use pesticides in cooperation with the national IR-4 program. This is the final report for this project which will be terminated and the funds redistributed between two other Inter-Regional 4 Research Projects, 0500-00007-093, �Residue Analysis of Minor Use Pesticides� and 0500-00007-094-00D, �Field Testing of Minor Use Pesticides. Research was conducted to develop new pest control tools in ornamental crops. The ARS, Inter-Regional Project Number-4 unit at Prosser, Washington, and Northwest Horticulture, Mabton, Washington, cooperated to collect and submit data required to establish registrations for thirteen new herbicides based on 163 field trials. Completed trials include the herbicides trifluralin + isoxaben, flumioxazin, dimethenamid-p, dimethenamid-p + pendimethalin, mesotrione, sulfentrazone, sulfentrazone + prodiamine, sulfosulfuron, oxyflourfen + prodiamine, sulfosulfuron, isoxaben, indaziflam, and dithiopyr tested on 18 to 33 container grown ornamental species each year. The completed research will support new registrations of these herbicides in the tested ornamental crops. In addition, nine crop safety studies were conducted with carfentrazone, flufenacet, clomazone, mesotrione, pendimethalin, pyroxasulfone, saflufenacil, sulfentrazone, and penoxsulam on peas, asparagus, Timothy hay, wine grapes, blueberry, dill, edamame, and cherry.

Replaced 0500- 00007-078-00D (8/10). Research was conducted to develop new pest control tools in ornamental crops. The ARS, Inter-Regional Project Number-4 unit at Prosser, Washington, and Northwest Horticulture, Mabton, Washington, cooperated to collect and submit data required to establish registrations for nine new herbicides based on 27 field trials. Completed trials include the herbicides oxyflourfen + prodiamine, sulfentrazone, mesotrione, carfentrazone, isoxaben, indaziflam, and dimethenamid-p + pendimethalin, pendimethalin alone, and pinoxsulam tested on 14 ornamental species (gaura, catmint, sedum rose mallow, sage, daylily, alumroot, delosperma, carex, perennial phlox, lilac, feather grass, hosta, purple coneflower, blueberry, asparagus, cherry, and wine grape). The completed research will support new registrations of these herbicides in the tested ornamental crops. In addition, four crop safety studies were conducted on asparagus, Timothy hay, wine grapes, and blueberry with five herbicides (carfentrazone, flufenacet, mesotrione, and pendimethalin). Accomplishments 01 Field tests were conducted by ARS scientists in the Vegetable and Forage Crops Research Unit in Prosser, Washington. This research determined the response of fourteen ornamental plant species to new herbicides and four food crops to four new herbicides. The crop safety of the herbicides on these species was previously unknown. Data generated will be used to support registrations of these herbicides on new ornamental species and field crops. This research will aid in development of new pest control options for ornamental plants and specialty food crops.

The research conducted in this project is part of the national effort of ARS to generate information supporting the registration of minor use pesticides in cooperation with the national IR-4 program. Research was conducted to develop new pest control tools in ornamental crops, which is often not cost effective for industry, leaving a shortage of available tools for growers of horticultural crops to use. The ARS, IR- 4 unit at Prosser, WA, and Northwest Horticulture, Mabton, WA, cooperated to collect and submit data required to establish registrations for ten new herbicides based on 32 field trials. Completed trials include oxyflourfen + prodiamine, flumioxazin, sulfentrazone + prodiamine, dimethenamid-p + pendimethalin, mesotrione, trifluralin + isoxaben, isoxaben, indaziflam, sulfosulfuron, and dimethenamid-p tested on 18 plant species (Box elder, camellia, canna, Carex, daylily, dogweed, burning bush, elm, geranium, hawthorn, eastern hemlock, western hemlock, liatris, rose mallow, muhly, oak, pampas grass, and peony). The completed research will support new registrations of these herbicides in the tested ornamental crops. In addition, five crop safety studies were conducted on peas, asparagus, Timothy hay, wine grapes, and blueberry with five herbicides (saflufenacil, carfentrazone, flufenacet, mesotrione, and pendimethalin). Accomplishments 01 Determination of plant response to new herbicides. This research determined the response of eighteen ornamental plant species to new herbicides and five food crops to five herbicides. The crop safety of th herbicides on these species was previously unknown. Field tests were conducted by ARS scientists in the Vegetable and Forage Crops Research Unit in Prosser, WA, on eighteen container grown ornamental species. Dat generated will be used to support registrations of these herbicides on n ornamental species and field crops. This research will aid in developmen of pest control for ornamental plants and specialty food crops.
