White Bean

A study was conducted over a 3-yr period (2004–2006) in Ontario to evaluate various weed management programs in white bean (Phaseolus vulgaris L.). Herbicide treatments evaluated caused no visible injury in white bean. Trifluralin provided 12% (percentage points) greater control of common lambsquarters (Chenopodium album L.) than s-metolachlor. There was no benefit of tank-mixing s-metolachlor and trifluralin for yield and profitability compared with either trifluralin or s-metolachlor alone. The postemergence (POST ) application of bentazon plus fomesafen following a soil-applied herbicide resulted in improved control of common lambsquarters by 15%. Two inter-row cultivations following a soil-applied herbicide resulted in improved control of redroot pigweed (Amaranthus retroflexus L.), common lambsquarters, and green foxtail [Setaria viridis (L.) Beauv.]. The addition of imazethapyr (60% of label dose; 45 g a.i. ha-1) to the soil-applied herbicide resulted in improved control of redroot pigweed (+6%), common lambsquarters (+16%), and green foxtail (+6%). The profit margin tended to increase if more than just a grass preplant-incorporated (PPI) herbicide was used. The best profit margin was with a grass PPI herbicide alone plus cultivation. The profit margin also tended to increase with the use of cultivation rather than a broadleaf POST herbicide.

This study compared allelopathic effects of three winter cereals, winter wheat (Triticum aestivum), winter rye (Secale cereale) and winter triticale (Triticale hexaploide Lart.) on seed germination of redroot pigweed (Amaranthus retroflexus), green foxtail (Setaria viridis) and common bean (Phaseolus vulgaris). Extracts from field- and greenhouse-grown rye significantly inhibited germination of redroot pigweed and green foxtail, yet had no effect on the navy bean cultivar Envoy. In a second study, rye, wheat and triticale provided similar inhibition of weed seed germination; however, effects on bean germination differed between cereals. Bean seed germination was significantly reduced (P < 0.05) by winter wheat and winter triticale, but unaffected by rye. Key words: Weed seed germination, bean, weed management, cover crops

Crop Maturity

Field studies were conducted from 1991 to 1994 to investigate the effectiveness of reduced rates of bentazon in tank-mixtures with imazethapyr, thifensulfuron, or HOE 075032 for improved control of redroot pigweed and common lambsquarters in navy bean. Tank-mixtures of bentazon at 600 g ai/ha plus imazethapyr at 25 g/ha or HOE 075032 at 5 to 15 g/ha controlled both redroot pigweed and common lambsquarters. These rates represent an approximate 45% reduction in total amount of active ingredient needed to control these weeds compared with full label rates. Bentazon tank-mixtures with 2 or 4 g/ha of thifensulfuron controlled these weeds but caused severe injury and delayed crop maturity. In greenhouse studies, the GR25for HOE 075032 in navy bean was > 90 g/ha, while in soybean it was 16 to 24 g/ha.

Six field experiments were conducted over a two-year period (2013 and 2014) to evaluate the tolerance of white bean and spectrum of weeds controlled with halosulfuron applied preplant incorporated (PPI) alone or tankmixed with trifluralin, pendimethalin, EPTC, dimethenamid-P, or S-metolachlor. Halosulfuron applied alone or in tankmix with trifluralin, pendimethalin, EPTC, dimethenamid-P, or S-metolachlor caused 2% or less visible injury 1 and 4 weeks after emergence (WAE). Halosulfuron applied PPI controlled common lamb's-quarters, wild mustard, redroot pigweed, and common ragweed greater than 90% and green foxtail less than 60% 4 and 8 WAE. Weed biomass and density followed a similar pattern. White bean yield with halosulfuron applied alone or in tankmix with the same herbicides was equivalent to the weed-free control.

Six field experiments were conducted during 2015 to 2017 in Ontario, Canada, to determine the efficacy of pethoxamid applied alone, and in combination with broadleaf herbicides, for the control of annual grass and broadleaved weeds in white navy bean. Visible injury was generally minimal (0 to 8%) with herbicide treatments evaluated. Weed control was variable depending on the weed species evaluated. Pethoxamid,S-metolachlor, halosulfuron, imazethapyr, sulfentrazone, pethoxamid + halosulfuron, pethoxamid + imazethapyr, and pethoxamid + sulfentrazone controlled redroot pigweed 82 to 98%; common ragweed 19 to 93%; common lambsquarters 49 to 84%; and green foxtail 47 to 92% in white bean. Weed biomass and weed density reductions were similar to visible control ratings for herbicides evaluated. Weed interference delayed white bean maturity and reduced yield by 50% in this study. Weed interference in plots sprayed with pethoxamid,S-metolachlor, and sulfentrazone reduced white bean yield 36%. White bean yield was similar to the weed-free with other herbicides evaluated. This study concludes that there is potential for the tank-mix of pethoxamid with halosulfuron, imazethapyr, or sulfentrazone for weed control in white bean production.

The Impact

The impact of two weed management systems on the weed seed reserves of the soil, on the yearly weed problem, and on corn (Zea maysL.) production was assessed where corn was grown under furrow irrigation for 6 consecutive years. In one system, 2.2 kg/ha of atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] was applied annually to the same plots as a preemergence treatment. In the other system, a mixture of 1.7 kg/ha of atrazine plus 2.2 kg/ha of alachlor [2-chloro-2′,6′-diethyl-N-(methoxymethyl)acetanilide] was applied preemergence, followed by a postemergence application of 0.6 kg/ha of the alkanolamine salts of 2,4-D [(2,4-dichlorophenoxy)acetic acid]. The response of weeds and corn is presented only where atrazine was applied annually because the results were similar between both weed management systems. Weed seeds from eight annual species were identified, with redroot pigweed (Amaranthus retroflexusL. ♯ AMARE) and common lambsquarters (Chenopodium album♯ CHEAL) comprising 82 and 12%, respectively, of the initial 1.3 billion weed seeds/ha that were present in the upper 25 cm of the soil profile. After the sixth cropping year, the overall decline in the total number of redroot pigweed and common lambsquarters seeds was 99 and 94%, respectively. Very few weeds produced seeds during the first 5 yr, and no weed seeds were produced during the sixth year where atrazine was applied annually. When the use of atrazine was discontinued on one-half of each plot at the beginning of the fourth year, the weed seed reserve in soil began to increase due to an increase in the weed population. After 3 yr of not using atrazine, the weed seed reserve in soil had built up to over 648 million seeds/ha, and was then within 50% of the initial weed seed population. In the fifth and sixth years, grain yields were reduced 39 and 14%, respectively, where atrazine had been discontinued after 3 yr.

Seed Yields

Four field trials were conducted over a three-year period (2011–2013) in southwestern Ontario to evaluate the level of weed control provided by various halosulfuron tankmixes applied preplant incorporated (PPI) in white bean. Trifluralin, s-metolachlor, halosulfuron, and imazethapyr applied alone or in combination caused 4% or less visible injury 1 and 4 weeks after emergence (WAE) in white bean. Trifluralin, s-metolachlor, halosulfuron, and imazethapyr applied PPI provided 80–96%, 84–95%, 83–100%, and 75–92% control of redroot pigweed; 19–28%, 30–40%, 97–99%, and 73–84% control of common ragweed; 94–96%, 63–82%, 96–100%, and 96–100% control of common lambsquarters; 14-15%, 12–35%, 100%, and 96–97% control of wild mustard; and 96–97%, 95–97%, 53–56%, and 80–82% control of green foxtail, respectively. The two- and three-way tankmixes of halosulfuron with trifluralin, s-metolachlor, or imazethapyr provided 85–100% control of redroot pigweed, 90–98% control of common ragweed, 97–100% control of common lambsquarters, 100% control of wild mustard, and 93–98% control of green foxtail. Weed density, weed biomass and white bean seed yields reflected the level of visible weed control.

A total of six field experiments were conducted in southwestern Ontario over a 3-yr period (2016, 2017, 2018) to evaluate the efficacy of trifluralin and halosulfuron applied preplant incorporated (PPI) for weed management in white bean. Trifluralin, halosulfuron, and trifluralin + halosulfuron applied PPI caused as much as 2%, 6%, and 8% white bean injury, respectively. Weed interference delayed maturity and reduced white bean yield 56% compared with the weed-free control. Weed interference with trifluralin and halosulfuron applied alone reduced white bean seed yield as much as 35% and 29%, respectively; however, white bean seed yield with the trifluralin + halosulfuron tankmixes was similar to the weed-free control. Trifluralin, halosulfuron, and trifluralin + halosulfuron applied PPI provided 6%–12%, 75%–92%, and 71%–95% control of velvetleaf; 89%–95%, 93%–98%, and 96%–99% control of pigweed species; 5%–18%, 82%–96%, and 90%–97% control of common ragweed; 90%–97%, 81%–97%, and 95%–99% control of common lambsquarters; 23%–43%, 55%–88%, and 83%–96% control of flower-of-an-hour; 4%–25%, 94%–100%, and 95%–100% control of wild mustard; 96%–100%, 18%–45%, and 97%–100% control of barnyardgrass; and 92%–98%, 21%–40%, and 93%–98% control of green foxtail, respectively. Results indicated that low rates of trifluralin tank-mixed with halosulfuron has the potential to control problematic weeds and improve white bean yields in Ontario.

A new herbicide antidote, N,N-diallyl-2, 2-dichloro acetamide (hereafter referred to as R-25788) used in combination with EPTC (S-ethyl dipropylthiocarbamate), as seed treatments or as mixed sprays, protected corn (Zea mays L.) from herbicide injury in growth room and field trials. In growth room tests R-25788 gave partial protection from EPTC injury to sorghum (Sorghum vulgare Pers.) but not to winter rape (Brassica napus L.), turnip (Brassica rapa L.), white bean (Phaseolus vulgaris L.), redroot pigweed (Amaranthus retroflexus L.), lambsquarter (Chenopodium album L.), crabgrass (Digitaria sanguinalis (L.) Scop.), and green foxtail (Setaria viridis (L.) Beauv.). The antidote alone did not affect the crops or weeds.
