Book Description
XtendFlex® soybean is a new trait platform which confers resistance to three herbicide sites of action that include the active ingredients dicamba, glyphosate, and glufosinate. The ability to use these three herbicides in one system has generated new management questions. Field and greenhouse experiments were conducted in 2019 and 2020 to: 1) investigate weed control systems in conventional and no-tillage XtendFlex® soybean, and 2) identify any antagonistic or synergistic responses from herbicide-tank mixtures used in this system. Control of glyphosate-resistant (GR) waterhemp was optimized with PRE flumioxazin followed by (fb) POST glufosinate or dicamba alone or in combination with each other or glyphosate. Two-pass POST systems also controlled GR waterhemp as long as dicamba and/or glufosinate was used in each application. GR horseweed control was exceptional with all herbicide programs evaluated, except glyphosate alone EPOS or POST. Annual grass control was reduced with EPOS and POST glufosinate + dicamba tank-mixtures. In contrast, this combination was often additive or synergistic for both broadleaf and grass weed control in the greenhouse. Several glyphosate + glufosinate combinations were antagonistic, especially with broadleaf weeds. Dicamba + glyphosate was often antagonistic in the greenhouse but was additive or synergistic for GR waterhemp and GR horseweed control in the field. Antagonisms were often observed when all three herbicides were applied together; however, not all antagonisms resulted in poor control. This research provides growers insight into management strategies for various agronomically important weeds in XtendFlex® soybean. .

Book Description
Glyphosate-resistant soybeans, Glycine max (L.) Merr., enable flexibility in the timing of weed removal from the soybean agroecosystem. In 2002, 2003, and 2004, field studies were conducted in central and northwestern Missouri to investigate how arthropods are affected by glyphosate-resistant soybean weed management when exposed to different weed removal times and weed species compositions. Sixty percent of arthropod groups investigated were affected by weed management. Arthropods were most influenced by weed removal timing and exhibited preferences for either weedy soybean habitats with delayed weed removal or soybean habitats with reduced weed density from early weed removal. Ground-dwelling arthropods, especially Araneae and Carabidae, were supported by increased weediness. Carabids were 1.5--2 times more abundant in the weediest treatment (season-long mixed grass and broadleaf weeds) than in the weed-free control treatment. Soybean habitats with prolonged weediness supported 10 of 15 foliage-dwelling arthropod groups with significant weed removal timing main effect results, including the total natural enemy and total phytophagous arthropod groups. Treatments with reduced weediness supported the greatest abundance of green stink bug, Acrosternum hilare (Say); potato leafhopper, Empoasca fabae (Harris); bean leaf beetle, Cerotoma trifurcata (Forster); and grape colaspis, Colaspis brunnea (Fabricius). Wireworm sampling results indicated that weed removal timing and not weed species composition affect the presence of Elateridae larvae (wireworms). Results from this study indicate that glyphosate-resistant soybean weed management impacts the taxonomic composition and abundance of arthropods in soybean agroecosystems; however disadvantages have yet to be elucidated.
