IPM Oklahoma!

Corn & Sorghum


Sorghum field

Corn and sorghum are important crops for Oklahoma producers. More than 350 thousand acres of corn and 340 thousand acres of sorghum were grown in 2008. Most of the corn and sorghum grown in Oklahoma is used to feed cattle and other livestock. Corn production practices have changed dramatically with the development and adoption of transgenic varieties that contain genetics for weed and insect control and the need to grow corn with less water. So far, sorghum variety development has not followed the transgenic trend, but new varieties are available that offer competitively high yields and make a good choice for a summer cash crop. Today, new pest management challenges await corn and sorghum producers, but fortunately IPM programs are flexible enough to meet those challenges.
