Priorities

Category Rank Pest Type Pest Crop Stage Priority
Extension/Outreach 1 All 6- to 12-Inch Shoot Demonstration and education regarding cull pile management, specifically disposal, placement and composting of piles along with the associated advantages/disadvantages in disease and insect control.
Extension/Outreach 2 All 6- to 12-Inch Shoot Continue Integrated Pest management (IPM) education and on-farm demonstration plots.
Extension/Outreach 3 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 4 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.
Regulatory 1 All 6- to 12-Inch Shoot In order for Michigan onion growers to remain competitive and produce a quality product, it is imperative that the following pesticides be retained until effective and cost efficient pesticides are identified and registered: • Fungicides: chlorothalonil (Bravo, Echo, Equus), mancozeb (Dithane, Manzate, Manex II, Penncozeb), maneb (Manex), iprodione (Iprodione, Rovral). • Insecticides: chlorpyrifos (Lorsban), methomyl (Lannate), pyrethroids (Ambush, Ammo, Pounce). • Herbicides: oxyfluorfen (Goal), pendimethalin (Prowl), s-metolachlor (Dual Magnum), bromoxynil (Buctril) , sethoxydim (Poast), fluazifop-p (Fusilade), clethodim (Select).
Regulatory 2 All 6- to 12-Inch Shoot For the reasons stated previously, it is important that full registration of the following products be expedited: • Insecticide: fipronil (Regent) • Herbicide: dimethenamid (Outlook)
Research 1 All 6- to 12-Inch Shoot Develop management strategies for thrips based on the biology of the insect, dispersal patterns and interaction with foliar diseases.
Research 2 All 6- to 12-Inch Shoot Develop management strategies to control black mold.
Research 3 All 6- to 12-Inch Shoot Identify onion varieties suitable for Michigan that are resistant to black mold and thrips.
Research 4 All 6- to 12-Inch Shoot Identify the source of infection and appropriate crop management techniques for bacterial soft rot.
Research 5 All 6- to 12-Inch Shoot Identify effective reduced-risk fungicides and/or biocontrol agents, develop disease predictors and determine rotational strategies to manage foliar blights on onions.
Research 6 All 6- to 12-Inch Shoot Identify effective reduced-risk herbicides and develop alternative weed control methods for yellow nutsedge.
Research 7 All 6- to 12-Inch Shoot Evaluate cover crops and bio-fumigants for nematode, insect, disease, and weed management.
Research 8 All 6- to 12-Inch Shoot Develop improved facilities and disease management strategies for harvesting and storing onions.
Research 9 All 6- to 12-Inch Shoot Develop a rapid diagnostic tool to determine aster leafhopper infectivity rates for use in combination with economic thresholds to trigger control measures.
