Winged SCA in Hill

Winged sugarcane aphids have been found in Hill County in the Johnsongrass where they overwintered. These aphids have the ability to move to sorghum fields, as well as other Johnsongrass patches and volunteer sorghum. It is recommended to being scouting sorghum for the aphids 3-4 weeks post-emergence. Most seed treatments should provide protection for at least 4 weeks, but varying environmental conditions (rain, soil moisture, ect) may affect their potency.

Because effective control depends on timing sprays according to population numbers, early scouting may be essential in preventing economic damage in fields.

Mosquito season is upon us! Make sure you use insect repellent while outdoors, especially in the mornings and evenings. The Zika virus (as well as other diseases) is not being transmitted by mosquitoes in the United States, but it is a possibility.

Pest Update

Pest Update:

Some varieties without resistance may have disease due to the cool temperatures and wet weather. Scout fields for leaf and stripe rust, septoria, powdery mildew, and tan spot. We have mostly been seeing rusts, with a little bit of septoria and powdery mildew, and some scarce signs of tan spot. Many varieties are resistant to disease, but if the cool wet weather continues disease may move up to the flag leaf, and (depending on the cost) a treatment may be warranted.

Very few aphids (greenbug, BCOA, ect) have been seen due to the cooler weather which slows their reproduction and growth. No fall armyworms have been seen but may start to arrive soon.
