Priorities

Category	Rank	Pest Type	Pest	Crop Stage	Priority
Extension/Outreach	1	All		6- to 12-Inch Shoot	Educate and reduce fears of the public concerning genetically modified products and how they are safe, if consumed.
Extension/Outreach	2	All		6- to 12-Inch Shoot	Inform growers that granular treatments placed within the whorls are more effective than using insecticide sprays for first generation European corn borers. Stress that applications should be made May – early June for control of this pest.
Extension/Outreach	3	All		6- to 12-Inch Shoot	Inform growers that rotation helps control rootworm larvae and controls for rootworms are not needed, if sweet corn is followed by another crop other than corn.
Extension/Outreach	4	All		6- to 12-Inch Shoot	Inform growers that white grubs and wireworms are generally more of a problem in corn when planted in areas previously in sod.
Extension/Outreach	5	All		6- to 12-Inch Shoot	Educate growers concerning importance of application timing for control of common stalk borer and southwestern corn borer.
Regulatory	1	All		6- to 12-Inch Shoot	Assist in the review process by speeding up the process of obtaining use permits for genetically modified varieties.
Regulatory	2	All		6- to 12-Inch Shoot	Registration of mesotrione (Callisto) herbicide for annual broadleaf weed control.
Regulatory	3	All		6- to 12-Inch Shoot	Registration of foramsulfuron (Option) annual and perennial grass and broadleaf weed control.
Regulatory	4	All		6- to 12-Inch Shoot	Streamlined Section-18 process.
Research	1	All		6- to 12-Inch Shoot	Development of corn earworm resistant varieties that are free of the “Bt” gene.
Research	2	All		6- to 12-Inch Shoot	Development of varieties that can tolerate and/or resistant to damage caused by corn earworm and European corn borer.
Research	3	All		6- to 12-Inch Shoot	Development of “Bt” varieties which have greater flavor.
Research	4	All		6- to 12-Inch Shoot	Investigate products that are effective in controlling both the corn earworm and European corn borer.
Research	5	All		6- to 12-Inch Shoot	Development of varieties with resistance to the downy mildews. With the possible threat of introduction of Philippine downy mildew (Peronosclerospora philippinensis) and brown striped downy mildew (Sclerophthora rayssiae var. zeae) investigation of resistance should be a priority.
Research	6	All		6- to 12-Inch Shoot	Develop varieties resistant to rust.
Research	7	All		6- to 12-Inch Shoot	Develop IMI, glufosinate-consumer-acceptable, and sethoxydim resistant varieties.
Research	8	All		6- to 12-Inch Shoot	Develop varieties that may tolerate late season pests (insects and diseases).
