Michigan Celery PMSP

Priorities

Category Rank Pest Type Pest Crop Stage Priority
Extension/Outreach 1 All 6- to 12-Inch Shoot As new products and methods become available, alert the industry of any effects they may have on the crop with regard to interactions in the field and in tank mixes.
Extension/Outreach 2 All 6- to 12-Inch Shoot Emphasize scouting and IPM.
Extension/Outreach 3 All 6- to 12-Inch Shoot Emphasize farm and greenhouse ecology regarding whole system interactions, as described in Michigan Field Crop Ecology: Managing Biological Processes for Productivity and Environmental Quality (MSU Extension Bulletin E2646).
Extension/Outreach 4 All 6- to 12-Inch Shoot Demonstration and education regarding optimum spray patterns, drying times, environmental conditions and use of equipment in pesticide application.
Extension/Outreach 5 All 6- to 12-Inch Shoot Demonstrate spray technology as a means to reduce application rates and increase spray coverage efficiency.
Extension/Outreach 6 All 6- to 12-Inch Shoot More about the biology and potential significance of nematodes as pests in Michigan.
Regulatory 1 All 6- to 12-Inch Shoot Celery growers have a limited selection of products, which makes it difficult to manage resistance as their choices for rotation narrow. In order for Michigan celery growers to remain competitive and produce a quality product, it is imperative that the following pesticides be retained: ! Fungicide: Bravo (chlorothalonil - broad spectrum, cost effective: nothing currently available compares with its efficacy). ! Insecticides: Lannate (methomyl - broad spectrum, cost effective), Vydate (oxamyl - only product registered for carrot weevil, important for nematode control), Orthene (acephate - systemic, broad spectrum), Ambush/Pounce (permethrin - broad spectrum, fast acting, short PHI). ! Herbicides: Dual Magnum (metolachlor - suppresses nutsedge and annual grasses), Lorox (linuron) and Caparol (prometryn) (both are broad-spectrum and are versatile with pre- and post-emergence use).
Regulatory 2 All 6- to 12-Inch Shoot For the reasons stated previously, it is important that registration of the following products be expedited: ! Fungicide: Topsin-M (thiophanate-methyl) to fill the gap left by the cancellation of Benlate (benomyl), which was an important tool in halting disease once it had started. ! Insecticide: Provado (imidacloprid) has the same active ingredient as Admire but is less expensive.
Regulatory 3 All 6- to 12-Inch Shoot Clarification is needed on pesticide labels for greenhouse use.
Research 1 All 6- to 12-Inch Shoot Develop a rapid diagnostic tool to determine aster leaf hopper infectivity rates for use in combination with economic thresholds to trigger control measures.
Research 2 All 6- to 12-Inch Shoot Breed for resistance to Fusarium and other diseases.
Research 3 All 6- to 12-Inch Shoot Develop disease predictor models for foliar blights.
Research 4 All 6- to 12-Inch Shoot Evaluate the fungicides Quadris and Tilt for possible growth regulator effects.
Research 5 All 6- to 12-Inch Shoot Evaluate biopesticides, induced-resistance products, and other currently unregistered
Research 6 All 6- to 12-Inch Shoot Evaluate trap crops and other alternatives for nematode management.
Research 7 All 6- to 12-Inch Shoot Evaluate broad-spectrum, systemic insecticides for use in resistance management programs.
Research 8 All 6- to 12-Inch Shoot Evaluate control measures in the greenhouse, including the use of fungicides, insecticides and cultural methods, with regard to their impact on disease and pest suppression in the field.
Research 9 All 6- to 12-Inch Shoot Conduct herbicide resistance studies on groundsel and other weeds to find alternatives for their control.
