2013 WASHINGTON RED RASPBERRY COMMISSION RESEARCH PROPOSAL New Project Proposal Proposed Duration: (1 year) Project Title: Testing herbicides for weed control in red raspberries. PI: Tim Miller Organization: <strong>Washington</strong> State University Title: Extension Weed Scientist Phone: (360) 848-6138 Email: twmiller@wsu.edu Address: 16650 State Route 536 City/State/Zip: Mount Vernon, WA 98273 Cooperators: The anticipated cooperator is Sakuma Brothers Farm, Bow, WA Year Initiated 2013 Current Year 2013 Terminating Year 2013 Total Project Request: Year 1 $4,595 Year 2 $0 Year 3 $0 Other funding sources: Herbicides are generally provided by the manufacturer. Description: Weeds continue to be problematic in red raspberry production. In order to better manage them, it would be beneficial to gain registrations for new herbicides. A thorough testing of new herbicides alone and in combination with existing products is necessary to achieve both improved weed control while maintaining crop safety. Products of interest are Stinger (clopyralid), Facet (quinclorac), Treevix (saflufenacil), and Alion (indaziflam). Sequential applications of these products will be tested for efficacy on various weed species and for crop safety in this project. Justification and Background: Perennial weed species generally become more important the longer raspberry blocks are left in production. These weeds often will outlive the raspberry crop and are also difficult to control in the break crop between raspberry plantings, so they generally remain a problem in the subsequent raspberry planting. Yet another difficulty with perennial weeds in raspberry is the physical interference to berry drop using machine harvesters, which may result in berry loss. They also impact harvest of hand-picked fruit, reducing the efficiency of hand harvest by making berries harder to find and pick. Perennial weeds frequently become established the first couple of seasons on a new raspberry block, when raspberry plants are small and not as competitive. Often, these weeds are present in the field prior to transplanting baby raspberries. If not controlled when the infestation is relatively small, perennial weeds become increasingly difficult to kill, ballooning herbicide and labor costs and becoming a major factor in reducing the longevity of raspberry plantings. Trials with Stinger in healthy raspberries over the last few years have been encouraging. 069
Importantly, floricane injury and berry harvest have not been significantly impacted by these applications. Since postemergence (POST) treatments can be made when weeds are visible and thus to areas known to be infested with perennial weeds, cost of these treatments may be significantly lower than broadcast applications to the full block. Additionally, if good to excellent weed control results from these applications, slight crop injury due to the herbicide is more acceptable if it occurs only on selected areas of the field. More reliable crop injury data resulting from applications of these products is needed to document that they are safe for use in raspberry if registrations are to result, however. Treevix (BASF) and Alion (Bayer) are two new herbicides that recently gained federal registrations in certain orchard crops. Initial data in raspberry is promising, with Treevix as a cane burning herbicide similar in activity to Goal (oxyfluorfen) and Alion providing residual control of germinating weed seeds. Dr. Ed Peachey at Oregon State University is also conducting herbicide work in red raspberry, with both of us conducting preliminary crop safety (nonresidue) trials with IR-4 with Facet. We are also cooperating with Dr. Doug Doohan at Ohio State University on our investigations with Stinger. I am unaware of any weed management projects in raspberry occurring in Idaho or British Columbia. Relationship to WRRC Research Priority(s): #2 Priority, Weed Management Objectives (2013): To test several non-labeled herbicides in various sequences or mixtures for control of several perennial weeds in established red raspberries. Procedures: Plots will be established in 2013 in established raspberries. Herbicide applications will be made for several combinations of herbicides at cane burning time in early spring (Treevix and Alion) and late spring (Stinger and Facet). A typical application sequence could be Treevix + Alion in April followed by Stinger in late May. Most sequences/combinations of these herbicides will be included in this trial, as well as combinations and sequences with other common residual herbicides such as Sinbar (terbacil), simazine, diuron, and Callisto (mesotrione). Weed control will be evaluated, as will herbicide effects on raspberry yield, berry size, and primocane growth. Anticipated Benefits and Information Transfer: (100 words maximum) If positive, data from this experiment will be used to support new herbicide registrations in raspberries for these products. The data resulting from these studies will be disseminated through extension bulletins and during grower meetings sponsored by extension faculty and the agricultural industry. 070
