Priorities

Category	Rank	Pest Type	Pest	Crop Stage	Priority
Extension/Outreach	1	All		6- to 12-Inch Shoot	Need a handout listing plant-back restrictions for herbicides, particularly the sulfonylureas
Extension/Outreach	2	All		6- to 12-Inch Shoot	Need to maintain and preserve IPM agent and Extension Specialist positions working in vegetable production
Extension/Outreach	3	All		6- to 12-Inch Shoot	Need Extension publication on organic vegetable production; this publication should coincide with the National Organic Production (NOP) guidelines for example: address uncomposted N sources, lack of standardized labeling for organic products
Regulatory	1	All		6- to 12-Inch Shoot	Must have replacement for diazinon – critical for early season control of fire ant, wireworm, and grubs
Regulatory	2	All		6- to 12-Inch Shoot	Need to amend fire ant bait labels to allow use in fields – application may need to be at destruction of previous crop - primarily corn – perhaps a bare ground treatment
Regulatory	3	All		6- to 12-Inch Shoot	The development of glyphosate-tolerant sugarbeets is causing the loss of older products such as Spin-Aid and Nortron which are still important products for spinach growers
Regulatory	4	All		6- to 12-Inch Shoot	Need to decrease harvest interval of Ridomil Gold from 21 d to 14 or 15 d
Regulatory	5	All		6- to 12-Inch Shoot	Reduce PHI for Dual Magnum (24c) – primarily for fresh market
Research	1	All		6- to 12-Inch Shoot	Need better herbicides to control troublesome broadleaf weeds such as purslane, Virginia copperleaf, London rocket, lambsquarter, shepherd’s purse, and wild carrot – these weeds have become more prominent since the loss of Bladex and Lasso
Research	2	All		6- to 12-Inch Shoot	Need to evaluate alternative weed control chemistries for pre-plant incorporated, preemergence, and postemergence weed control
Research	3	All		6- to 12-Inch Shoot	Need research on disease management of Phytopthora rot
Research	4	All		6- to 12-Inch Shoot	Need fungicide that can be used on both fresh and processed spinach
Research	5	All		6- to 12-Inch Shoot	There is a distinct need for fungicides with alternate chemistry to the strobilurins
Research	6	All		6- to 12-Inch Shoot	Need more research on disease management tools for organic spinach production
Research	7	All		6- to 12-Inch Shoot	Need more research on weed management tools for organic spinach production
Research	8	All		6- to 12-Inch Shoot	Need research on disease management of black smutty rot – this disease is not only a processing problem – what effect does crop rotation have?
