Abstract BACKGROUND Mirdametinib is an investigational, oral, selective MEK1/2 inhibitor (MEKi) with high blood-brain-barrier penetration. We hypothesized mirdametinib would benefit patients pediatric low-grade gliomas (pLGG) and launched SJ901 (NCT04923126) to determine the recommended Phase 2 dose (RP2D), safety, efficacy. METHODS 1 required be >2 <25 years-old, MEKi-naive, have recurrent/progressive pLGG biopsy-proven MAPK pathway activation (except BRAF V600). Three levels...
Due to the increased adoption of dicamba-tolerant cotton (Gossypium hirsutum L.) and soybean [Glycine max (L.) Merr.], near-by sensitive broadleaf crops such as peanut (Arachis hypogaea are at an risk for off-target movement events. Limited data on response multiple exposure events reduced rates glyphosate plus dicamba available. Therefore, objective this study was determine impact low yield grade across locations in southeast southwest production regions U.S. In 2019/2020, field trials were...

Early leaf spot, caused by Passalora arachidicola, is the most prevalent and yield-limiting foliar disease affecting peanuts in Oklahoma. Quantifying yield losses associated with end-of-season defoliation early spot essential to evaluate effectiveness of currently deployed control strategies. To that end, a meta-analysis was conducted assess heterogeneity relationship between ELS (%) peanut (kg/ha) Spanish cultivars (A. hypogaea ssp. fastigiata var. vulgaris) Data were mined from fungicide...
Greenhouse experiments determined differences in imazaquin bioavailability over time under various soil moisture regimes. All soils were initially fortified with 63 ppb (w/w) of commercially formulated imazaquin. Treatments consisted maintaining at field capacity for 15 wk (FC), air-dry (AD), that was maintained 2 and then wet to intervals (2WAD), the initiation experiment (2WFC). Little dissipation occurred AD 100 d this study. Rapid first 35 other three treatments. Imazaquin half-life...
The concentration of three sulfonylurea herbicides in soil was determined by a modified petri dish bioassay procedure. method involved planting pregerminated seed selected species dishes containing 65 to 100 g treated and measuring the radicle lengths after 24 h. Chlorimuron detected two soils at 0.002 μg –1 using either corn, sorghum, or sicklepod as assay species. Chlorsulfuron CGA-131036 were 0.001 chlorsulfuron same level sicklepod. In contrast other methods, procedure described could be...
Abstract In Oklahoma, downy brome and cheat are difficult-to-control winter annual grasses. the past, infested most of wheat hectares harvested in Oklahoma. Biotypes that cross-resistant to acetolactate synthase–inhibiting herbicides have left growers with minimal management options for conventional herbicide-tolerant systems. Field trials near Lahoma, 2019–2020 2020–2021 evaluated integrated using three strategies: planting date (optimal, delayed, late), cultivar selection (high low...

Chloropicrin was ineffective at reducing V. dahliae. The application provided a 7 10% reduction in incidence wilt; however, there no or Applications reduced but did not impact yield, Although had minor dahliae lack response quality limits use these chemicals production system.

Abstract Halauxifen plus florasulam, thifensulfuron fluroxypyr, and bromoxynil bicyclopyrone are three, relatively new POST premix herbicides developed for control of broadleaf weeds in winter wheat. These herbicides, along with older products, were evaluated their horseweed Altus, Perkins, Ponca City, Oklahoma, during the spring 2017 2018. Horseweed has become a critical weed Oklahoma because its extensive germination window, changes tillage practices, increase herbicide-resistant biotypes....
Field studies were conducted from 2007 to 2010 evaluate the response of peanut cultivars different fungicides, application timings, and methods. Overall, fungicides reduced Sclerotinia blight incidence increased pod yields when applied susceptible partially resistant cultivars. Disease suppression was greater full fungicide rates preventatively; however, between treated plots similar. Lower levels disease higher achieved with cultivar Tamrun OL07 compared Flavor Runner 458 OL 02. Despite...

Research was conducted to determine the effects of tillage on fluometuron and norflurazon loss in runoff when applied preemergence cotton. Cumulative water concentrations were not affected by systems. In 1992, no-till system had less sediment than conventional system. Tillage systems did affect 1993. The highest amount total occurred with whereas reduced lowest There no differences cumulative between as loss, This research indicates that, while conservation may reduce it necessarily be best...
Wheat ( Triticum aestivum L.) production in the southern Great Plains is a unique enterprise that provides both high‐quality forage and grain crop within same growing season. However, information on fertility management programs to maximize beef dual‐use wheat system lacking. A 3‐yr, field‐scale study was initiated Tillman clay loam near Vernon, TX, 1999 (i) determine influence of P fertilizer placement forage, beef, from wheat, (ii) compare economic costs returns grain‐only systems.

Peanut (Arachis hypogaea L.) is grown extensively in several counties West Texas. Sclerotinia blight, caused by the soilborne fungus minor Jagger, an increasingly important disease throughout this region. In September of 2007, diseased peanut plants (cv. Tamrun OL02) exhibiting symptoms blight (2,4) were collected from a commercial farm Gaines County during regional survey. Infected stem sections surface disinfested 0.5% sodium hypochlorite for 1 min, air dried, and placed petri dishes...

ABSTRACT Cultivar selection is one of the most economically important decisions made by peanut producers. The development genotypes capable maintaining yield and quality under a wide range conditions so that profitability can be maximized. Issues such as declining irrigation capacity diseases limit production in parts Texas. Efforts Texas AgriLife Peanut Breeding Program are to develop breeding lines with improved potential, total sound mature kernels (TSMK), disease resistance. trials were...
