“…Application of oxadiargyl resulted in no marked injury to valerian at any rate or day after application. In contrast, at least in part, Alebrahim et al (2012) reported that application of oxadiargyl caused 1 to 23% injury to potato, but three weeks after application the plants had recovered. Nethra and Jagannath (2011) showed that maize and sunflower injuries increased when oxadiargyl concentrations were increased.…”

Valerian (Valeriana officinalis L.) is a medicinal plant, but its cultivation is restricted by weed competition. Therefore, three rates (0.75X, 1X, and 1.25X, where X is equal to the recommended dose of haloxyfop-R (methyl ester), sethoxydim, oxadiargyl, bentazon, oxadiazon, and oxyfluorfen) were applied at the 3-4 leaf stages to valerian plants. This application was done to select the herbicide type and rate for post-controlling broadleaf and grasses weeds in this species. Herbicide injury, Soil-Plant Analyses Development (SPAD) reading, number of leaves per plant, stem diameter, and fresh and dry weights were determined 10, 20, and 30 days after herbicide application. Oxyfluorfen application caused the most herbicide injury followed by bentazon. Injury increased as the rate and the days after application increased. Oxadiazon only caused significant damage 30 days after application under all three rates. Other treatments showed no marked injuries under any rate or date after application, as compared with the control. Effects on other measured traits depended on the trait, herbicide, and herbicide rate. The highest SPAD, leaf number, shoot diameter, fresh weight and dry weight, was recorded under application of 30 mg a.i. ∙ kg-1soil oxadiargyl and 90 mg a.i. ∙ kg-1soil oxadiazon, 81 mg a.i. ∙ kg-1soil haloxyfop-R, 37.5 mg a.i. ∙ kg-1soil oxadiargyl, 22.5 mg a.i. ∙ kg-1soil oxadiargyl, 81 mg a.i. ∙ kg-1soil haloxyfop-R, and 81 mg a.i. ∙ kg-1soil haloxyfop-R, respectively. To sum up, the results showed that sethoxydim, oxadiargyl, and haloxyfop-R produced no significant symptoms of phytotoxicity or reduction of measured traits. This means that oxadiargyl, haloxyfop-R, and sethoxydim may be used safely for weed control of valerian at the rates used in this experiment under similar conditions.

“…In other studies, the herbicide applied in pre-or post-emergence caused chlorosis and necrosis to the older leaves of plants (DITTMAR et al, 2015), with phytotoxicity scores ranging from 3% to 24% (ALEBRAHIM et al, 2012). However, in some cases, the results depended on the cultivar tested (FELIPE et al, 2006), indicating a variable response among potato genotypes to the herbicide (FRIESEN; WALL, 1984).…”

“…Still, most reports in the literature on its selectivity for potato plants (ALEBRAHIM et al, 2012;BOYDSTON et al, 2012;DITTMAR et al, 2015;FELIPE et al, 2006;GRICHAR et al, 2003;HUTCHINSON et al, 2005aHUTCHINSON et al, ,b, 2006HUTCHINSON, 2007;WILSON et al, 2002;ZAGONEL et al, 1999a,b) study only pre-emergence applications. Metribuzin inhibits electron transport in Photosystem II at the photochemical stage of photosynthesis, is a triazinone, and is registered for potato cultivation at doses of 360 and 720 g ha -1 in pre-emergence or up to a 5.0 cm height for early applications (RODRIGUES; ALMEIDA, 2011).…”

Metribuzin is the most commonly used herbicide in potato cultivation in Brazil, but there are few reports in literature regarding its selectivity, especially when applied to post-emergent potato plants. The objective of this study was to evaluate the selectivity of the herbicide metribuzin for potato cultivation, applied in pre-and post-emergence. Two experiments were carried out under field conditions, one with the Agata cultivar and another with the Atlantic cultivar. A randomized block experimental design, with a subdivided plot (5 × 3) and four replications, was used in both experiments. Plot experiments consisted of five doses of metribuzin (0, 120, 240, 360, and 480 g a.i. ha -1 ), studied for pre-emergence, as well as three doses (0, 120, and 192 g a.i. ha -1 ) studied for post-emergence. Metribuzin was selective for the Agata and Atlantic cultivars at doses of up to 480 g ha -1 for pre-emergence, as well as at 120 or 192 g ha -1 for post-emergence, applied seven days after hilling. Key words: Agata. Atlantic. Phytotoxicity. Solanum tuberosum L. ResumoO metribuzin é o herbicida mais utilizado na cultura da batata no Brasil, porém existem poucos relatos na literatura sobre a sua seletividade, principalmente, quando aplicado na pós-emergência das plantas de batata. Com o objetivo de estudar a seletividade do herbicida metribuzin para a cultura da batata, aplicadoem pré e pós-emergência, dois experimentos foram desenvolvidos em condições de campo, um com a cultivar Ágata e outro com a Atlantic. Nos dois experimentos, o delineamento experimental foi o de blocos ao acaso, em esquema de parcela subdividida (5 x 3), com quatro repetições. Nas parcelas foram estudadas cinco doses de metribuzin (0, 120, 240, 360, 480 g i.a. ha -1 ), em pré-emergência, após o plantio da batata, combinadas à aplicação de três doses desse herbicida (0, 120 e 192 g i.a. ha -1 ), em pós-emergência das plantas, nas subparcelas. O metribuzin foi seletivo para as cultivares Ágata e Atlantic em doses de até 480 g ha -1 em pré-emergência combinado com 120 ou 192 g ha -1 em pós-emergência, aplicado aos sete dias após a prática da amontoa.

“…Metribuzin damage on potato was increased over time under pre-emergence application, but at postemergence application, potato recovered partially after 3 weeks, although the injury was not negligible (Alebrahim et al, 2012). In agreement with our results, Ali and Honermeier (2016) reported that Planta Daninha 2020;38:e020223839 -https://doi.org/10.1590/S0100-83582020380100073 8/10 phenmedipham application was safe on Cynara cardunculus where injury symptoms increased until 14 DAT, followed by plant recovery.…”

“…They also reported that oxyfluorfen injury increased up to 30 DAT, whereas in our study oxadiargyl injury increased up to 10 DAT (3.3 to 7%), and then was followed by recovery (Table 3). Oxadiargyl damage on potato increased up to 3 weeks after treatment (WAT), after which plants started to recover (Alebrahim et al, 2012). (Grichar et al, 2009) also reported that flufenacet tank mixed with metribuzin resulted in at least 72% reduction in sesame (sesamum indicum) stand in Texas (U.S.A).…”
