IMPACT OF MICRO-RATES OF DICAMBA OR 2,4-D CHOLINE ON SENSITIVE SOYBEAN TYPES IN NEBRASKA

Major Goals (Objectives) include:(I) Impact of dicamba micro-rates on sensitive soybeana. To establish baseline data on the injury of potentially sensitive crops (e.g. non-DTsoybeans) to various rates of dicamba.b. To establish baseline data on the injury of tomato and grapes to various rates ofdicamba.c. To establish baseline data on the injury of Roundup-Ready soybeans to ultra-lowrates of Dicamba (Hormesis or not).d. To collect photos of dicamba's injury symptoms (time-lapse photography) in orderto develop educational materials and presentations that can be disseminated tofarmers, crop consultants and State and local agencies through traditional and webbasedtechnologies.(II) Impact of 2,4-D choline micro rates on sensitive soybeans.a. To establish baseline data on the injury of potentially sensitive crops to variousrates of 2,4-D choline.
