“…Scenario 5: Palmer amaranth and kochia control in dry edible bean. Corn and soybean represent crops with a substantial number of available herbicides; most crops grown in the Central Great Plains (and elsewhere) have far fewer registered herbicide options (Adjesiwor et al, 2020;Soltani et al, 2018). As an example, we evaluated the cost of weed control and effective mixtures in dry edible bean.…”

“…It has been shown that herbicides, such as flumioxazin and pyroxasulfone, could either be safe or provide good residual weed control in dry bean (Adjesiwor et al., 2020; Soltani et al., 2020; Taziar et al., 2016). Flumioxazin is an N ‐phenylphthalimide herbicide that inhibits protoporphyrinogen oxidase (Niekamp et al., 1999), while pyroxasulfone is an isoxazoline herbicide that inhibits very long chain fatty acid synthesis in broadleaf weeds (Tanetani et al., 2009).…”

Field experiments were conducted in 2021 and 2022 to evaluate the effect of irrigation timing on S‐ethyl‐N,N‐dipropylthiocarbamate (EPTC), flumioxazin, pyroxasulfone, and flumioxazin + pyroxasulfone weed control efficacy and safety in dry bean (Phaseolus vulgaris L.). Treatments consisted of EPTC (3430 g ai ha−1), flumioxazin (53.6 g ai ha−1), pyroxasulfone (119 g ai ha−1), and flumioxazin + pyroxasulfone (70.4 + 89.3 g ai ha−1) incorporated with overhead irrigation at 1, 4, and 8 days after herbicide treatment (DAT). A nontreated and hand‐weeded check were included for comparison. Delaying irrigation until 8 DAT resulted in 11% and 19% injury in the pyroxasulfone and flumioxazin + pyroxasulfone treatments, respectively, but the crop recovered within 5 weeks after treatment. Delaying irrigation until 8 DAT increased total weed dry weight by 52%. Generally, flumioxazin + pyroxasulfone provided better weed control compared to flumioxazin or pyroxasulfone applied alone. Irrigation timing did not influence dry bean yield. Seed yield was 160 kg ha−1 in the nontreated check and 2521 kg ha−1 in the hand‐weeded check. Seed yield in the flumioxazin + pyroxasulfone treatment (2425 kg ha−1) was similar to the hand‐weeded check. Flumioxazin + pyroxasulfone provided very good weed control with acceptable crop safety. While irrigation timing may play a role in flumioxazin or pyroxasulfone injury, other soil and environmental factors may influence dry bean response to these herbicides.

“…Nebraska ranks fourth in dry edible bean production in the United States, representing an annual value of more than $94 million, wherein more than 70% of the dry edible bean production occurs in the Nebraska panhandle region (Lucier and Davis 2020;Soltani et al 2018a;Thomas et al 2001). Weed competition with dry edible bean can result in a significant yield loss because dry edible bean is a weak competitor with weeds, primarily because of its slow growth rate and short stature (Adjesiwor et al 2020;Beiermann et al 2021a). The potential yield loss in dry edible beans in the United States and Canada, if weeds are left unmanaged, is estimated be 71.4%, compared to 50% and 52.1% in corn (Zea mays L.) and soybean (Glycine max L.…”

Control of acetolactate synthase-inhibiting herbicide-resistant Palmer amaranth (Amaranthus palmeri) with sequential applications of dimethenamid-Pin dry edible bean

In Western Nebraska, Palmer amaranth is becoming more prevalent where acetolactate synthase (ALS)−inhibitor−resistant biotypes are widespread. There are limited effective postemergence (POST) herbicides labeled for ALS−inhibitor−resistant Palmer amaranth control in dry edible bean. The objective of this study was to evaluate the efficacy of dimethenamid−P in a sequential preemergence (PRE) fb (followed by) POST program at two POST application timings, V1 and V3, for controlling ALS−inhibitor−resistant Palmer amaranth in dry edible bean. A field study was conducted in 2019, 2020, and 2021 in Scottsbluff, NE. PRE−alone programs of pendimethalin + dimethenamid−P provided inconsistent Palmer amaranth control. Dimethenamid−P applied POST following a PRE application of pendimethalin + dimethenamid−P provided effective Palmer amaranth control (>90%) at 4 WAV3 only at the V1 application timing in 2019. In 2020 and 2021 Dimethenamid−P applied POST at V1 and V3 following a PRE application of pendimethalin + dimethenamid−P provided 99% and 98% Palmer amaranth control at 4 WAV3 and 98% and 94% Palmer amaranth control at harvest, respectively. Palmer amaranth biomass was reduced 95−99% and 96−98% compared to the non−treated control when dimethenamid−P was applied POST at V1 and V3, respectively, following a PRE application of pendimethalin + dimethenamid−P in 2020 and 2021. Mixing dimethenamid−P with imazamox + bentazon POST performed similarly to the fomesafen−containing treatments and dimethenamid−P alone POST. Dimethenamid−P applied POST following a PRE application of pendimethalin + dimethenamid−P resulted in similar yield as the fomesafen−containing treatments. If fomesafen is not an option due to the crop rotation interval restriction, using dimethenamid−P in a sequential PRE fb POST program is the only effective alternative to control ALS−inhibitor−resistant Palmer amaranth in Nebraska. The use of dimethenamid−P in a sequential PRE fb POST program, alone or mixed with foliar−active herbicides should be considered by dry edible bean growers who are dealing with ALS−inhibitor−resistant Palmer amaranth.
