Soybean Research Verification Program Update August 17, 2012
Author: Chris Grimes, Program Associate - Soybean/Wheat Verification Coordinator

Irrigation continues to be the main focus in the program, although we did catch a much needed rain on the fields in the River Valley and Central part of the State where we were limited on irrigation.  Several of the fields in the program have either reached irrigation termination or are real close. Insect and disease pressure was low for the most part, but there are a couple of fields requiring treatment.

CountyVariety StageGeneral Information
Arkansas-1HBK 5221R4Insects remain under control following the application of Belt on 7/27. This location depends totally on surface water. The reservoir water has been depleted, but we got a 2” rain on 8/13 and more rain Saturday.
Arkansas-2Halo 4:94R52” rain on 8/13. No insect or disease pressure so far. The field has been irrigated 4 times.
ChicotOzark & OsageR5Belt was applied on 8/10 with good results before loopers did too much damage. A fungicide was applied late last week for frogeye leaf spot and general seed quality improvement. The field has been irrigated 6 times.
Conway (DC)Halo 5:25R3 Field received 1” rain on 8-13-12 that really helped, since we are limited on irrigation. Insect and disease pressure was light this week. Insecticide applied last week for worms did a good job.
Crittenden-1Halo 4:65R6Irrigation has been terminated on this field. Stinkbugs are averaging 4/25 sweeps and we are watching field close for increased pressure.
Crittenden-2Halo 4:65R5.5Field was irrigated on 8-15-12. Picked up bean leaf beetles this week, but defoliation levels remain low. Will continue watch for increase in defoliation.
CrossProgeny 4807R5Irrigation was started back on 8-16-12. Field reached treatment level for bollworms and Belt was recommended for control.
DeshaArmor 47R44R6As of 8/15, the field had ½ treatment level for stinkbugs. Will scout this Wednesday to determine if a treatment is needed.
DrewArmor 47R44R6Irrigation has been terminated. Insecticide applied on 7/30 has held well.
Faulkner (DC)Halo 5:25R3Didn’t get to visit field this week, because gate was locked.
GreeneAG 5503R3Started back with irrigation on 8-15-12. Insect and disease pressure remains low, so far. Did find a couple of spots in the field that has blister beetle pressure.
LafayetteDelta Grow 4880R6No insect pressure at this location. Irrigation has been terminated. The field was irrigated 3 times.
LawrencePio 94Y40R6Field received 0.3” rain and irrigation. Insect and disease pressure remains low.
MillerPio 94Y40R6Insect numbers remain very low. Irrigation has been terminated. The field received 7 pivot irrigations.
MississippiOsageR5The fungicide application did a good job on the frogeye that we picked up last week. Insect pressure remains light, so far.
Phillips-1Pio 94Y70R6.5Insect numbers remain low. The 7th and final irrigation was completed last week.
Phillips-2UA 4910R6.5Insect numbers remain low. The 7th and final irrigation is planned to begin Monday.
PoinsettArmor 48R40Late R5Insect and disease pressure was light again this week. Will need to irrigate when levees get dry enough to repull.
PrairieUA 4910Late R5Irrigation was started back on 8-15-12. Insect and disease pressure still remains low.
