Tolerance of dry beans to herbicides has been reported to be dependent on rate, cultivar, and environmental conditions (Bauer et al 1995;Blackshaw and Saindon 1996;Renner and Powell 1992;VanGessel et al 2000;Wilson and Miller 1991). Our research and that of others have shown that the various market classes of dry beans from different geographic origins and, therefore, different genetic backgrounds, respond differently to herbicides (Renner and Powell 2002;Sikkema et al 2004;Soltani et al 2003Soltani et al , 2004.…”

Tolerance of eight market classes of dry beans (black, brown, cranberry, kidney, otebo, pinto, white, and yellow eye beans) to the PRE application of linuron at the rate of 2.25 and 4.50 kg ai/ha was studied at two locations in Ontario, Canada, in 2003 and 2004. The eight market classes differed in their response to linuron. Linuron PRE caused as much as 43, 20, 7, 17, 54, 36, 56, and 12% visual injury in black, brown, cranberry, kidney, otebo, pinto, white, and yellow eye beans, respectively. Linuron PRE at 2.25 kg/ha reduced plant height 38% in otebo beans and 31% in white beans. Linuron PRE at 4.50 kg/ha reduced plant height 24 to 56% in black, brown, otebo, pinto, and white beans. Shoot dry weight was reduced in otebo beans by 56% and in white beans, by 46% at the low rate. Shoot dry weight was decreased 26 to 92% in black, otebo, pinto, white, and yellow eye beans at the high rate. There were no differences in the shoot dry weight of the other market classes. Linuron PRE at the low rate reduced otebo bean yield 42% and at the high rate reduced yields by 56, 74, and 61% in black, otebo, and white beans, respectively. There was no effect on the yield of other market classes. Differences in dry bean market class tolerance to linuron exists and may be summarized for these cultivars as cranberry > kidney > brown > yellow eye > pinto > black > white > otebo. Additional research is needed to determine if cultivars within a dry bean market class differ in their response to linuron.

“…have a risk of phytotoxicity as herbicide is most likely to easily reach the root system at planting since the tradition is to apply water to an opened planting hole followed by inserting a seedling into the hole. Such effects of herbicides, when applied at pre-planting, have been reported with other herbicides (Johnson 2008) and mixtures of s-metolachlor and flumetsulam in Lima Bean (Phaseolus lunatus) (Vangessel, Monks & Johnson 2000) and white bean, Phaseolus vulgaris L. (Soltani et al 2004). Trials in year 3 deliberately chose the i.a.p.…”

Herbicides are usually the first line of defence against weeds and form a formidable pair with mechanical control whether with machinery of hand hoeing. Due to the risk of weed resistance to herbicide control and environmental contamination, there is continuous need for new chemicals to be tested for control of weeds. In this work, the herbicide Bateleur Gold, a factory premix of s-metolachlor and flumetsulam was evaluated to establish the time and rate of application that would give efficacious weed control without causing phytotoxicity. In the first year, the herbicide was included in a screening trial comprising twelve herbicides arranged in a randomised complete block design. After good efficacy when applied immediately after planting, it was selected for further development. In the second year, in a split plot design with four blocks and four treatments, it was applied at 0.455 kg a.i ha -1 applied just after holing out (a.h.o) and at the same rate immediately after planting (i.a.p). A positive control Dual Magnum (smetolachlor) at 2.2 kg a.i.ha -1 i.a.p was used as a check and an untreated control was included. This trial showed that applied a.h.o, Bateleur Gold neither stunted Tobacco nor reduced yield but somewhat reduced weed efficacy especially overall (total weeds) nor grasses while the i.a.p. was ideal and showed no phytotoxicity and had good weed efficacy. In the third year, the i.a.p time of application was tested in a similar design but now more rates of Bateleur Gold were tested. The rates were, Bateleur Gold at 0.455, 0.92, 1.365 and 1.82 kg a.i.ha -1. Dual Magnum at 2.2 kg a.i.ha -1 i.a.p was again included as a check. This work confirmed the potential of the herbicide as a broad spectrum material and showed that the best rate that would ensure broad spectrum control was 0.92 kg a.i.ha-1. Further research could look at application of this material in irrigation water in order to cater for those farmers with centre pivots. In addition, although application a.h.o. does not cause stunting of Tobacco; more work may be needed to show this with greater confidence.

Ontario otebo bean growers have few herbicide options available for weed management. Six field trials were conducted in Ontario, Canada, over a 2 year period (2003 and 2004) to evaluate the tolerance of otebo bean to the postemergence (POST) application of bentazon at 1080 and 2160 g ai ha − 1 , fomesafen at 240 and 480 g ai ha − 1 , sethoxydim at 500 and 1000 g ai ha − 1 , quizalofop-p-ethyl at 72 and 144 g ai ha − 1 , imazamox plus fomesafen at 25 + 200 and 50 + 400 g ai ha − 1 , and imazamox plus bentazon at 25 + 600 and 50 + 1200 g ai ha − 1 . All treatments, including the untreated control, were maintained weedfree during the growing season. The POST application of bentazon, imazamox plus fomesafen, and imazamox plus bentazon caused as much as 9% visual injury and reduced the plant height ≤ 12%, reduced the shoot dry weight ≤ 32%, and delayed maturity but had no adverse effect on the yield of otebo bean. Fomesafen, sethoxydim, and quizalofop-p-ethyl applied POST caused as much as 8% visual injury but this was transient and had no adverse effect on the plant height, shoot dry weight, seed moisture content, and yield of otebo bean, except for quizalofop-p-ethyl, which reduced the shoot dry weight as much as 18%. Based on these results, bentazon, fomesafen, sethoxydim, quizalofop-p-ethyl, imazamox plus fomesafen, and imazamox plus bentazon applied POST have an adequate margin of crop safety for weed management in otebo bean production in Ontario. However, care must be taken to avoid spray overlaps to prevent injury from bentazon, imazamox plus fomesafen, and imazamox plus bentazon.Keywords: bentazon, fomesafen, imazamox, Phaseolus vulgaris , quizalofop-p-ethyl, sethoxydim.for use in Ontario. The lack of registered herbicides means high input costs for cultivation and hand-hoeing. In addition, the otebo bean yield and quality are reduced. Therefore, there is a great need for new weed control products to keep Ontario otebo bean production competitive.Bentazon is a selective benzothiadiazole postemergence (POST) herbicide that can provide effective control of broadleaf weeds, including common lambsquarters ( Chenopodium album L.), redroot pigweed ( Amaranthus retroflexus L.), purslane ( Portulaca oleracea L.), common ragweed ( Ambrosia artemisiifolia L.), wild radish ( Raphanus raphanistrum L.), hairy galinsoga ( Galinsoga ciliata ), common groundsel ( Senecio vulgaris ), jimsonweed ( Datura stramonium L.), giant ragweed ( Ambrosia trifida L.), velvetleaf ( Abutilon theophrasti Medic.), ladysthumb ( Polygonum persicaria L.), wild mustard ( Sinapis arvensis L.), cocklebur ( Xanthium strumarium L.), shepherd's purse ( Capsella bursa-pastoris (L.)
