Sugarcane Aphid Update

Sugarcane aphids continue to colonize Johnsongrass in Hill County and grow in number. Three sites were sampled on March 17th and all three were infested with SCA. The presence of large colonies this early in the year, most likely due to a milder winter, could indicate earlier infestations in sorghum.

No winged aphids were found on the 17th (3 sites) or the 25th (2 sites). This may be due to the cold weather and rains.

Bird Cherry-Oat Aphids

Bird Cherry-Oat Aphids (BCOA) have been on the increase in Hill County wheat fields, but population growth may have been slowed by the large number of beneficial predators and cold weather. Check out this article and scouting tips if you are finding the aphids in your fields. At the bottom there is a quick worksheet you can fill out to determine if a spray is economical.

Pest Update

Bird Cherry-Oat Aphids have been seen in low numbers on wheat across Hill county. Many beneficial predators (ladybugs, lacewings, ect) have also been seen and will help keep the aphid populations in check. Hessian Fly has also been observed in low numbers. Both of these pests are more significant in the fall, but large populations can still cause damage.

Wheat rust may begin to emerge soon due to last week's rain. If you have planted susceptible varieties, monitor your wheat carefully. A fungicide application may be warranted on susceptible varieties as rust pustules move up the plant to the newer leaves. Protecting the flag leaf is essential to maintain yields. There are many factors that go in to making decisions to spray fungicides for diseases on wheat, such as price of wheat, expected yield in that field, variety susceptibility, future weather conditions, and more.
