Shout out to Richard (Rick) DeLoughery, Area Agronomy Specialist & Mississippi County Program Leader for these updates:
Jake Mikels, consultant with Wheat Tech, here in Charleston, called to say they are finding SCA throughout Miss. County through Blodgett (Scott Co.). There are groups of 10 to 15 SCA every 4 to 5 flag leaves. Numbers are growing. Most fields are close to maturity and will be sprayed with a desiccant soon.
Marshall Meeks (with MFA at Benton (Scott Co.) sent: “Reports in new Madrid county.”
Michael Ray Johnson, consultant, reported: “SUGARCANE APHIDS ( MODERATE TO HEAVY) AROUND THE NEW MADRID HIGH SCHOOL NORTH OF RAIL ROAD TRACK. SEVERAL FIELDS AROUND HOLCOMB, MO WITH LIGHT APHIDS. FINDING APHIDS ( LIGHT ) AROUND DEXTER, MO.
STARTING TO DESICCATE SOME FIELDS AND WILL BE ADDING INSECTICIDE FOR CONTROL ON APHIDS.”
Smith Deline, consultant, reported: “I found SCA west of east prairie and also in the dogwood area. Found also in new Madrid county a few weeks ago.”
[The Dogwood community is NW of E. Prairie and south of Bertrand]
We treated for Sugar cane aphid in sorghum 3 weeks ago. We found the first colonies on sorghum in the cotton wood area. You really must search for the fist small colonies to get ahead of these aphids. They are capable of shutting down the combine at harvest due to the amount of honeydew they produce. They also reduce yield substantially. We have many acres of sorghum under surveillance and all required yellow sugar cane aphid control. Chemical control worked.
