GMO enhanced crops provide
growers and consumers with a
number of benefits. The
reluctance of consumers to
accept GMO sweet corn is a
barrier to their adoption.
Consumers need to be educated
on the advantages of GMO
crops. These advantages might
include for example; more
biodiversity, less pesticide use,
and human and environmental
safety. |

Corn earworm is one of the most
serious insect pests of sweet
corn and requires regular
insecticide sprays when
populations are high. Growers,
especially fresh market sweet
corn growers, need to be
educated regarding corn
earworm monitoring procedures
so that pesticide applications
can be reduced. The trapping
networks and information
delivery mechanisms regarding
this insect should be better
coordinated. |

Sweet corn diseases can
seriously reduce crop yield and
quality. Since the number of
fungicide products is limited to a
couple of modes of action, it is
imperative that disease
resistance management
schemes be implemented now to
retain the usefulness of these
products. Growers need more
information on how to implement
pesticide resistance
management for sweet corn
diseases. |

A number of pesticides are
labeled for field corn that may
have acceptable uses for sweet
corn. The possibility of
expanding the label to include
sweet corn should be
investigated for the following
products; Callisto, Camix,
Lumax, Option, Liberty, Poast,
acetachlor. Regulatory
agencies, the sweet corn
industry, land grant partners,
and manufacturers should seek
to support these labels. |

For some sweet corn insects,
control is achieved almost
exclusively through the use of
pyrethroid insecticides. Corn
earworm, European corn borer,
and the fall armyworm would
become serious problems if
these insecticides were lost.
There is a critical need to
maintain registration of these
insecticides. |

Registrants and regulatory
agencies should update
rotational restrictions regarding
atrazine use on sweet corn. The
current label is based on older,
higher use rates, usage patterns.
Sweet corn growers, who often
grow other vegetable crops in
their rotations, are now
unnecessarily restricted on
rotations. |

The widespread adoption of
Roundup Ready and Bt hybrids
has become a disincentive for the
development of new products.
The sweet corn industry needs
new pesticide products,
especially herbicides, to combat
newly invasive weeds, and weeds
which are becoming resistant to
current herbicides. Research
needs to continue into new
synthetic compounds so that
pests can be controlled as necessary. |

Common smut is one of the more
devastating sweet corn diseases.
Research is needed to screen
hybrids for reaction to common
smut, and investigate
mechanisms of resistance.
Hopefully this will lead to the
development of hybrids with
greater resistance to this disease. |

Leaf rust; timing of initial
applications of strobilurins needs
to be examined. Because these
compounds are more efficacious
than other fungicides, they may
be applied later in the disease
cycle, thus allowing for a better
assessment of whether chemical
control is actually needed.
Strobilurin-resistant fungi are
likely to occur- so resistance
management strategies should be
developed. Hybrid screening and
resistance breeding need to be
continued. |
