Herbicide evaluation for broadleaf weed control in direct-seeded broccoli
… in stand. All rates of oxyfluorfen completely controlled Venice mallow while only the 0.56 kg/ha rate of BAS 514 provided acceptable (>70%) control. Broccoli plants that survived preemergence applications of oxyfluorfen exhibited injury ranging from 32 to 97% 6 to 9 weeks after treatment. BAS …

Influence of Isoxaben Application Timing on Dissipation and Broadleaf Weed Control in Turf
Isoxaben is a preemergence (PRE) broadleaf herbicide used in turf and ornamentals. Field, greenhouse, and laboratory research evaluated this herbicide for PRE control of selected broadleaves in turf, suspected postemergence (POST) herbicidal effects, and the influence of application timings and …

Efficacy and selectivity of the herbicide rimsulfuron in potatoes [Solanum tuberosum], transplanted tomatoes [Lycopersicum esculentum], and transplanted peppers [Capsicum annum]
… for preemergence and postemergence grass and broadleaf weed control in Solanaceous vegetable crops. The efficacy and selectivity of rimsulfuron were determined in potatoes, transplanted tomatoes, and transplanted peppers in field studies in 1991, 1992, and 1993. Treatments included rimsulfuron …

Evaluation of florpyrauxifen-benzyl for use in pastures and hayfields
Weed control is a critical component in pastures and hayfields in order to ensure maximum forage yields. Typically, broadleaf weed control in pastures and hayfields is achieved through the use of synthetic auxin. However, these herbicides also control desirable broadleaf species such as forage …

Biochemical and molecular basis for metabolism-based atrazine resistance in Amaranthus tuberculatus
… is a commonly used herbicide for selective broadleaf weed control in maize (Zea mays). Rapid detoxification of s-triazine herbicides is the result of increased glutathione S-transferase (GST) activity in atrazine-tolerant crops such as maize and grain sorghum (Sorghum bicolor), or in …

Incorporating the Experimental Herbicide CGA 362622 into Cotton Weed Management Programs in Virginia
… increased, so has the need for more efficient weed control programs. Current cotton herbicides do not control all broadleaf weeds over the entire growing season, and many cotton herbicides must be applied at specific growth stages in order to reduce crop injury. CGA 362622 is an experimental …

Responses of selected chickpea cultivars to imidazolinone herbicide
Limitations to broadleaf weed management options in chickpea present obstacles for stable production. Even with low weed incidence, chickpea yield can be severely affected, creating need for an integrated weed management system. Due to zero-tillage commonly practiced in Saskatchewan, there is heavy …

Combination effect of ACP 2100, imazaquin and triclopyr on common dandelion and three Kentucky bluegrass turf types
… program, including growth regulation and broadleaf weed control. Field and greenhouse results indicated an antagonistic interaction between triclopyr and imazaquin for control of common dandelion (<i>Taraxacum officinale</i> Weber in Wigger). Addition of imazaquin at 276 g ha⁻¹ to …

Field, greenhouse, and laboratory evaluation of the efficacy and selectivity of the herbicide thifensulfuron for weed control in soybeans (Glycine max)
… Dupont de Nemours Company Inc. for postemergence broadleaf weed control in soybeans [Glycine max (L.) Merr]. Field studies evaluated the influence of adjuvants and chlorimuron upon the efficacy of thifensulfuron. Thifensulfuron applied alone provided smooth pigweed (Amaranthus hybridus L. #AMACH) …

Field efficacy and availability, movement, and persistence of ICIA-0051 herbicide in soils
… conducted in 1987 and 1988 determined the weed control efficacy of ICIA-0051 and SC-0774 in conventional and no-till systems of corn (<i>Zea mays</i> L.) culture. Results of the preemergence and postemergence applications of ICIA-0051, across all treatments after 8 weeks, showed 85% control …

Basis for Selectivity of Isoxaben in Ajuga (Ajuga reptans), Wintercreeper (Euonymus fortunie), and Dwarf Burning Bush (Euonymus alatus 'Compacta')
Isoxaben is a preemergence herbicide used for broadleaf weed control in turf and ornamentals. Although isoxaben can be used on a number of ornamentals, certain species are injured by isoxaben applications. The objectives of this research were: a) to evaluate the tolerance of ajuga, wintercreeper …
