STEPHANIE PORTER UPDATES



It has finally stopped raining. Even though we were supposed to have a cool down, it has continued to be very hot and humid. The fungicide on corn appears to be holding fungal diseases below the ear. I did see some Southern rust on the end rows of corn, but not bad as you go into the field. There are obvious disease differences on different hybrids. Corn is almost at full dent. Soybean disease symptoms of SDS are starting to show. Red crown rot has not been a major issue in Montgomery Co., but this year, this disease has unfortunately made its debut and is here to stay. Soybeans are at R4 growth stage.
