“…Regarding the use of saflufenacil with seven bean cultivars (e.g., from the black bean group, the carioca bean and the special bean), in which the method of application, the dose and the soil type were the same as in the present experiment, Diesel et al (2014) reported reductions in grain yield ranging from 65 to 100%; they highlighted a 98% reduction in the yield of the IPR-Tiziu cultivar and indicated that yield losses may be variable. Hekmat, Shropshire, Soltani, & Sikkema (2007) conducted a study to assess the sensitivity of eight commercial bean groups to sulfentrazone (840 g ha -1…”

“…The dose of 100 g ha -1 saflufenacil caused phytotoxicity and decreased the yield of the adzuki bean (Vigna angularis) and various types of common bean (e.g., Phaseolus vulgaris and Phaseolus lunatus) (Soltani et al, 2010). The response to saflufenacil in ten Brazilian common bean cultivars was evaluated by Diesel et al (2014), who reported that most of them were highly sensitive to the herbicide.…”

ABSTRACT. The temporal selectivity of an herbicide refers to the time interval required between its soil application and crop sowing to prevent damage to crop development and reproduction. Using field bioassays, this study aimed to determine the temporal sensitivity of the herbicide saflufenacil when used with a crop. The study was conducted in two time periods during 2011/2012 and 2012/2013 and employed a split-plot, randomized block experimental design. The main plots were assigned to seven time intervals between herbicide application and bean sowing (0, 5, 10, 15, 25, 35, and 50 days), and the subplots were assigned to groups in which saflufenacil was absent or present (0 and 29.4 g ai ha -1 ). We determined the stand and the plant height at 7, 14, and 21 days after sowing (DAS), and the first pod height, the number of pods per plant, the number of seeds per pod and the grain yield at maturity. Saflufenacil negatively affected the development of the IPR-Tiziu bean; at 21 DAS, the stand and the plant height at maturity were the variables most sensitive to the herbicide. A minimum interval of 15 days between herbicide spraying and bean sowing was necessary to prevent a reduction in grain yield.Keywords: persistence, Protox inhibitor, Phaseolus vulgaris, phytotoxicity.Seletividade temporal do herbicida saflufenacil à cultura do feijão em latossolo vermelho distroférrico RESUMO. A seletividade temporal de um herbicida diz respeito ao intervalo necessário entre sua aplicação no solo e a implantação de uma cultura, para não haver prejuízos ao seu desenvolvimento e reprodução. Este estudo objetivou, por meio de bioensaios a campo, determinar o tempo necessário entre a aplicação do herbicida saflufenacil no solo e a semeadura para conferir seletividade à cultura do feijão. Os estudos foram realizados em 2011/2012 e 2012/2013, em parcelas subdivididas. Nas parcelas principais foram alocados sete períodos entre a aplicação do herbicida e a semeadura de feijão (0, 5, 10, 15, 25, 35 e 50 dias) e nas subparcelas a ausência e presença de saflufenacil (0 e 29,4 g i.a. ha -1 ). Determinou-se o estande e altura de plantas aos 7, 14 e 21 dias após a semeadura (DAS) e de inserção da primeira vagem, número de vagens/planta, número de grãos/vagem e rendimento de grãos na maturação fisiológica. O desenvolvimento do feijão IPR-Tiziu foi reduzido pela presença de saflufenacil, sendo o estande aos 21 DAS e altura de planta na maturação fisiológica as variáveis com maior sensibilidade. Intervalo mínimo de 15 dias entre aplicação e semeadura foi necessário para não haver prejuízo ao rendimento de grãos.Palavras-chave: persistência, inibidor da Protox, Phaseolus vulgaris, fitotoxicidade.

“…However, there was a marked decrease in the performance of the herbicide after this period. According to Diesel (2014), the persistence of saflufenacil in Dystroferric Red Latosol, as determined by bioassays with cucumbers and beets, was between 25 and 35 DAA of the herbicide, which explains the low levels of control observed with time between sowing and application. These authors also found a high degree of variability in the tolerance of different bean varieties to saflufenacil.…”

The plants commonly known as morning glory belong to the genera Ipomoea and Merremia and are among the most important weeds in Brazil. Greenhouse studies were conducted in 2016/2017 to compare the susceptibility of different morning glory species-Ipomoea quamoclit, I. nil, I. hederifolia, I. triloba, Merremia aegyptia, and M. cissoides to soil-applied herbicides and to evaluate the effectiveness of these herbicides after periods of drought. In the first experiment, to evaluate the efficacy of each herbicide at pre-emergence stage, a fully randomized 6 (doses) x 6 (species) factorial experimental design with six replicates was used. The herbicides tebuthiuron (3,200; 1,600; 800; 400; 200 and 0.0 g a.i ha-1), amicarbazone (2,100; 1,050; 750; 375; 187 and 0.0 g a.i ha-1), sulfentrazone (1,200; 600; 300; 150 75 and 0.0 g a.i ha-1), mesotrione (240; 120; 60; 30; 15 and 0.0 g a.i ha-1), saflufenacil (200; 100; 50; 25; 12 and 0.0 g a.i ha-1), and imazapic (360; 180; 90; 45; 22 and 0.0 g a.i ha-1) were applied. Ipomoea hederifolia, I. nil, and I. quamoclit were most susceptible to saflufenacil; I. triloba and M. cissoides were most susceptible to tebuthiuron; and M. aegyptia was most susceptible to amicarbazone. Therefore, the best herbicide treatment depends on the species of morning glory. In the second experiment, to determine the effectiveness of herbicides after periods of drought, the treatments were arranged, for each herbicide, in a fully randomized 6 x 5 factorial design with four replicates, six species of morning glory, and five sowing times after periods of drought (0, 15, 30, 45, and 60 days after application (DAA) of the herbicides) relative to the application of the amicarbazone (1,050 g a.i ha-1), imazapic (180 g a.i ha-1), mesotrione (120 g a.i ha-1), saflufenacil (100 g a.i ha-1), sulfentrazone (600 g a.i ha-1), and tebuthiuron (1,600 g a.i ha-1). Herbicide effectiveness after periods of drought began to decrease after 15 days for saflufenacil; 30 days for imazapic, mesotrione, and tebuthiuron; 45 days for amicarbazone; and 60 days for sulfentrazone. Preemergence application of amicarbazone and sulfentrazone exhibited consistent efficacy during the drought periods, satisfactorily controlling the species of morning glory.

Adzuki bean is a niche market, high-value field crop suited to the temperate growing regions of the world. Adzuki bean lacks early season vigour and thus early season weed control is critical for profitable production. Efficacious application of preplant incorporated (PPI), preemergence (PRE), and, to a lesser degree, postemergence (POST) herbicides have been documented, however, the number of registered herbicides is currently limited due to the sensitivity of adzuki bean crops. In addition to the currently registered products, the literature shows the potential utility of cloransulam-methyl or halosulfuron applied PPI and (or) PRE, and imazamox or acifluorfen applied POST in adzuki. Furthermore, growers should avoid atrazine, metribuzin, EPTC, pethoxamid, pyroxasulfone, clomazone, flumioxazin, sulfentrazone, alachlor, dimethenamid-P, and S-metolachlor applied PPI and (or) PRE, and halosulfuron, thifensulfuron-methyl, and bentazon applied POST, due to poor adzuki bean tolerance to these herbicides. While crop tolerance research represents a growing body of work, there is a paucity of available weed control data to assist growers. The persistence of volunteer adzuki bean is a significant hurdle for adzuki bean growers. However, crop and herbicide mode-of-action rotation, in combination with early-season [PPI and (or) PRE] control, have demonstrated success. There is an ongoing need to evaluate weed control and expand the number of registered herbicides for adzuki bean growers.
