Field & Commercial Crops
Industry concerns over grain quality, along with increased production of specialty, identity-preserved and food-grade crops, have placed increased focus on grain quality and storage issues. Most damage that occurs during storage is caused by molds and insects. Grain spoilage occurs as microorganisms feed on teh nutrients in the grain. As they grow and develop, these microorganisms produce heat, which increases the temperature of the surrounding grain. This heating may result in hot spots. If the temperature and moisture in the grain are just right, the major mold species Apergillus, Fusarium and Pencillum may produce mycotoxins such as aflatoxin, fumonisin, DON …

Sp341-K Common Stalk Borer In Field Corn, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
The common stalk borer in Tennessee is reported to attack several crops in addition to field corn. However, the preferred host of the insect is giant ragweed. This preference is due to the largeness of the stem in which the larvae can mature. Fields of corn planted into a no-till situation are preferred by the moths because of the grassy weeds in those fields. The adult moth deposits eggs on grassy weeds in the early spring. Later, the larvae will migrate to any corn planted in the fields.

Sp341-Y Western Corn Rootworm, The University Of Tennessee Agricultural Extension Service
Field & Commercial Crops
Three species of corn rootworms are found in Tennessee. The Western corn rootworm is the most destructive of the three species. This insect is now prevalent from Texas to the Dakotas, and has moved into Tennessee within the past 10 to 15 years. Until 1955, this rootworm was found in Nebraska, Colorado, Kansas, South Dakota and Iowa. The Western corn rootworm has traditionally moved into the territory of the Northern corn rootworm, which is also found in Tennessee.
