“…Injury observed was stunting; however, the peanuts quickly recovered. This response is consistent with previous research where runner-and Virginia-type peanut injury from flumioxazin was transient and did not affect yields (Main et al 2003;Wilcut et al 2001).…”

“…Injury, with possible yield losses, from flumioxazin and norflurazon can be expected. However, flumioxazin injury is possibly caused by cool wet weather (Askew et al 1999;Main et al 2003;Wilcut et al 2001;Yoshida et al 1991), which may be avoided by a later planting date. Other research has demonstrated that flumioxazin provides growers with a good PRE herbicide option for dry peanut (Eastin et al 1993;Grichar and Colburn 1996;Main et al 2000;Wilcut and Cranmer 1997).…”

Green Peanut Tolerance to Preemergence and Postemergence Herbicides

et al. 2004

Field studies were conducted near Sparr, FL, in 2001 and 2002 to evaluate the response of ‘Valencia 102’ grown for the green peanut market (or boiling peanut) to preemergence (PRE) and postemergence (POST) applications of herbicides registered for dry peanut production (roasted market). Green peanut exhibited excellent tolerance to most PRE and POST treatments. There was minimal injury (8%) from flumioxazin applications when evaluated early season in both years, and peanut quickly recovered. Norflurazon caused chlorosis to peanut foliage (23%) in both years. Yield reduction was observed in 2001 for flumioxazin (15%), metolachlor (20%), and norflurazon (41%) compared with the untreated control. However, there were no yield reductions for any of the PRE treatments in 2002. Bentazon + paraquat early postemergence (EPOST) followed by (fb) 2,4-DB POST, bentazon + paraquat EPOST fb clethodim POST, and imazapic EPOST caused ≤5% injury and had no effect on yield in either year.

“…In previous research, only POST applications of chlorimuron had an influence on the incidence of TSWV in peanut (Prostko et al 2009). In other peanut research, applications of diclosulam (PPI), flumioxazin (PRE), imazapic (POST), paraquat (POST), and 2,4-DB (POST) did not affect the incidence of TSWV (Bailey et al 2000;Faircloth and Prostko 2010;Tubbs et al 2010;Wilcut et al 2001). The mechanism of how certain herbicides influence TSWV in peanut has not yet been discovered.…”

Peanut Tolerance to Pyroxasulfone

et al. 2011

Due to limited hectares and production in comparison to field corn, soybean, and wheat, commercial research and development efforts by major manufacturers for potential new peanut herbicides are minimal. Therefore, new herbicides developed for large hectare crops should be evaluated for potential use in peanut. Field trials were conducted in Ty Ty and Plains Georgia in 2007 and 2008 to evaluate the tolerance of peanut to PRE and POST applications of pyroxasulfone at five rates (0, 120, 240, 360, and 480 g ai/ha). Pyroxasulfone did not cause significant peanut injury at the Ty Ty location. In Plains, PRE applications of pyroxasulfone caused significant crop stunting, particularly at the 360 and 480 g/ha rates. In Ty Ty, PRE applications of pyroxasulfone also resulted in greater expression of tomato spotted wilt virus than POST applications. Peanut yields were not reduced by any rate or timing of pyroxasulfone. These results suggest that pyroxasulfone may have some potential to be utilized in peanut.Key Words: crop injury, tomato spotted wilt virus, yield.In 2010, peanut was planted on 522,000 ha in the U.S. (Anonymous 2011). In contrast, field corn, soybean, and wheat were planted on 36,000,000, 31,000,000, and 22,000,000 ha, respectively (Anonymous 2011). Consequently, commercial research and development efforts for new herbicides are focused in these crops and not in peanut Pyroxasulfone is an inhibitor of very-longchain-fatty acids and should be categorized within the K3 group of herbicides (Tanetani et al. 2009). Other common K3 herbicides include acetochlor, alachlor, butachlor, dimethenamid-p, flufenacet, Smetolachlor, and propachlor (Senseman 2007). Smetolachlor is frequently used in peanut for the control of various weeds including yellow nutsedge (Cyperus esculentus L.) and Benghal dayflower (Commelina benghalensis L.) (Grichar et al. 2001;Grichar et al. 2008;Prostko et al. 2005).Little information about the tolerance of legume crops to pyroxasulfone has been published in the literature. Although pyroxasulfone was initially targeted for PRE weed control in corn, soybean has shown good tolerance The soil type at the Ponder Research Station was a Tifton sand with 96% sand, 2% silt, 2% clay, 1.2% organic matter, and pH 6.0. The soil type at the Southwest Experiment Station was a Greenville sandy loam with 71% sand, 13% silt, 16% clay, 1% organic matter, and pH 6.0. Cultivars, planting dates, inverting, and harvest dates are presented in Table 1. Common production practices and Cooperative Extension recommendations were used at all times. Supplemental irrigation was applied as needed.Herbicide treatments were arranged in a factorial design that included two application timings (PRE or POST) and five pyroxasulfone rates (0, 120, 240, 360, and 480 g ai/ha). All treatments were replicated four times. PRE treatments were activated with irrigation within 48 hours of application. POST treatments of pyroxasulfone were applied between 44 and 51 days after peanut planting and included a non-ionic surfactant...

RESUMO -O objetivo deste estudo foi avaliar a atividade residual de herbicidas utilizados no manejo de plantas daninhas em pré-emergência da cultura da soja, bem como verificar seus efeitos sobre o milheto cultivado em sucessão. Utilizaram-se parcelas de 80 m 2 , em delineamento de blocos casualizados, com quatro repetições, em esquema de parcelas subdivididas 5 x 4, correspondendo à aplicação dos herbicidas imazaquin (0,160 kg ha -1 ), diclosulam (0,035 kg ha ) e uma testemunha, aplicados logo após a semeadura do cultivar de soja Msoy-6101. Nas subparcelas, realizou-se a semeadura do milheto, cultivar ADR-7010, em quatro períodos, correspondendo a 0, 40, 80 e 120 dias após a aplicação dos herbicidas (DAA). Durante a condução do ensaio, foram determinados os níveis de intoxicação, estande, altura e massa seca da parte aérea das plantas de milheto. No final do ciclo foi avaliado o rendimento de grãos da cultura. O híbrido de milheto ADR-7010 apresentou elevada sensibilidade com relação à atividade residual dos herbicidas sulfentrazone, diclosulam e imazaquin quando cultivado logo após a aplicação destes. A bioatividade dos herbicidas imazaquin, diclosulam e flumioxazin não foi suficiente para alterar o rendimento de grãos do milheto cultivado em sucessão à soja (120 DAA), mostrando que esse intervalo de tempo é suficiente para dissipação desses herbicidas. Dos herbicidas pré-emergentes avaliados, o sulfentrazone apresentou maior atividade residual, influenciado negativamente o rendimento da cultura durante o intervalo de tempo estudado.Palavras-chave: carryover, sulfentrazone, diclosulam, imazaquin, flumioxazin, Pennisetum glaucum.ABSTRACT -The objective of this study was to evaluate the persistence of herbicides applied in pre-emergence in soybean crop and the effects of these herbicides on pearl millet grown in succession. The herbicides imazaquin (0.160 kg ha -1 ), diclosulam (0.035 kg ha -1 ), sulfentrazone (0.600 kg ha -1 ), and fumioxazin (0.050 kg ha -1 ) were used immediately after sowing of soybean Msoy-6101, in plots of 80 m 2 , divided into sub-plots of 20 m 2 (5 x 4 m). A randomized block design with four replications was used in a split-plot scheme 5 x 4. In the sub-plots, pearl millet hybrid ADR-7010 was sown in four periods after herbicide application, corresponding to 0, 40, 80 and 120 days after herbicide application (DAA). Pear millet injury, stand, height and dry biomass of the plant were evaluated at 7, 15, and 28 days after emergence; crop grain yield was evaluated at the end of the cycle. Pearl millet hybrid ADR-7010 showed high sensitivity to the residual activity of sulfentrazone, imazaquin, and diclosulam when grown immediately after herbicide application. The bioactivity of imazaquin, diclosulam, and flumioxazin was not sufficient to affect grain yield of millet grown after soybean (120 DAA), suggesting that this interval is sufficiently long for dissipation of these herbicides. Among the pre-emergent herbicides, sulfentrazone showed longer residual activity, negatively influencing the c...
