10. Summary 1.) Location and Planting Date variables had A major impact on yield, 3.) The impact of Planting Date on yield varied by Location, 4.) There were no differences in yield among pesticide treatments 5.) Leaf area index did not differ by pesticide type. 6.) The lack of difference in pesticide treatment did not vary by location or planting date. Thus pesticides had no measurable impact on yield.

12. Kudzu Bug Update Doug Johnson Extension Entomologist

13. The following information concerning the Kudzu bug Is provided to you by in large from my colleagues in the Cooperative Extension Service and Agricultural Experiment Station as summarized below.

19. Life History (GA) Overwinters as an adult Overwintered adults become active – Feed on many plants, – seek reproductive hosts e.g. kudzu and Soybean. Usually infest kudzu 1 st but in 2012 infested early planted soybean. Soybean becomes attractive at about V-3 Overwintered adults lay eggs for many weeks.

20. Life History Cont. (GA) 1 st Gen (F1) egg-to adult development about – 6-8 wks. Spring – 6 wks. June – 1 st Gen Adults present Mid-June – F1 Adults disperse from kudzu to soybean for several weeks while overwintered adults still laying eggs. During this dispersal re-infestation can/will occur After dispersal a SINGLE application is very effective.

21. Treatment Threshold Scouting use a 15” sweep net – 1 immature kudzu bug per sweep – Don’t spray too early, if well timed a single application will preserve soybean yield. Only treat before immature appears if – Adult numbers are very high and – Plants are under significant stress from another factor. e.g. drought.

22. Yield data has been collected from 19 replicated trials in Georgia and South Carolina. Yield was numerically reduced in unprotected plots in 16 of 19 trials. An average yield loss of 18 percent and a range from 0-47 percent. Kudzu bugs feed on plant sap and can be considered a stress inducing pest Yield Impact
