Potential for delayed orchardgrass seeding during glyphosate-resistant alfalfa establishment
Few herbicides are labeled for weed control when establishing alfalfa (Medicago sativa L.)-grass mixtures. Varying the planting date of the grass in relation to alfalfa and adjusting herbicide application timing could improve weed control and forage grass safety. The research objective was to evaluate the use of glyphosate [N-(phosphonomethyl) glycine] for weed control in seedling ...

Weed control in organic farming
Probably the most cost-intensive and time-consuming operation in organic farming is the elimination of weeds at different stages of plant development. Due to the impossibility of herbicides application, the processing must be performed mechanically. For this purpose farmers use a wide variety of rotary and striegel harrows, cultivators and tillers for interrow processing and ...

Glyphosate-based herbicides on weeds management and maize performance under conservation agriculture practices in eastern Kenya
A three-season research study was conducted at Embu Agricultural Research Station farm to determine the effect of glyphosate-based herbicides on weeds management and maize ( Zea mays L. ) performance under zero-tillage conservation agriculture practice. Glyphosate herbicide sprays were prepared from Roundup Turbo product at the rate of 2.5 L ha –1 and Roundup Weathermax at 1.5, 2.5 and 3.0 L ...

Organic and conventional production systems in the wisconsin integrated cropping systems trials: i. Productivity 1990–2002
During the last half-century, agriculture in the upper U.S. Midwest has changed from limited-input, integrated grain–livestock systems to primarily high-input specialized livestock or grain systems. This trend has spawned a debate regarding which cropping systems are more sustainable and led to the question: can diverse, low-input cropping systems (organic systems) be as productive as ...

Hairy Vetch management for no-till organic corn production
Rolling-crimping to control hairy vetch (Vicia villosa Roth) may make organic no-till corn (Zea mays L.) possible. This study investigated how rolling-crimping date and growth stage of the cover crop affected hairy vetch control and if a rolled-crimped hairy vetch cover crop could supply weed control for no-till corn. Hairy vetch was planted in late August and was rolled and crimped and planted ...

De-inking paper sludge amendment affects weeds in the presence or absence of herbicide in a soybean-corn rotation
The application of de-inking paper sludge (DPS), a C-rich but N-poor soil amendment, can sometimes decrease plant growth. This property needs to be investigated to develop the knowledge and management methods necessary for potential weed control. Today, there is no information on the effectiveness of using DPS to control weeds within a soybean [Glycine max (L.) Merr.]-corn (Zea mays L.) rotation. ...

Statistical evaluation of the early-stage development of Jatropha energy plantations in Northeastern Mexico
A systematic evaluation of agricultural factors affecting the adaptation of the tropical oil plant Jatropha curcas L. to the semi-arid subtropical climate in Northeastern Mexico has been conducted. The factors studied include plant density and topology, as well as fungi and virus abundances. A multiple regression analysis shows that total fruit production can be well predicted by the area per ...

Methodology to assess the hydrological impact of weed control practices with a view to management of Mediterranean winegrowing catchments
This paper proposes a methodology to assist water resources managers in assessing the hydrological impact of weed control practices in Mediterranean winegrowing catchments. The methodology is based on a spatial representation of practices and its integration in a distributed hydrologic model. The representation is based on the search for indicators that can be used to attribute a distribution of ...

Making Better Herbicide Decisions with Weed Density Mapping
Proper weed control early during the growing season is essential for reducing nutrient competition, gaining optimal crop health, and preventing yield loss. Weed management in corn and soybeans can be an extremely difficult problem to tackle and, if left unmanaged, can cause nearly a 52% corn yield loss and 49% yield loss in soybeans according to research conducted by the Weed Science Society of ...

Behavior of atrazine in Limited Irrigation Cropping Systems in Colorado: Prior use is important
Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full irrigation cropping systems. These systems ...

Effects of the herbicide imazapyr on juvenile Oregon spotted frogs
Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater‐breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the ...

Behavior of atrazine in limited irrigation cropping systems in Colorado: prior use is important
Received for publication October 28, 2008. Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full ...

Variation in amphibian response to two formulations of glyphosate‐based herbicides
Variation in toxicity among formulations and species makes it difficult to extrapolate results to all species and all formulations of herbicides. We exposed larval wood frogs (Lithobates sylvaticus) from four populations to two glyphosate‐based herbicides, Roundup Weed and Grass Control™ and Roundup WeatherMax™. 96 hour LC50 values for both formulations varied among the populations (RWGC: 0.14 ...

Why consider pre-emergent herbicide?
Resistant weeds, dicamba training, new EPA rules and regulations, and ag companies being bought or merging together have been a few of the topics found in many ag media and publications this winter. In summary, things are continually changing in agriculture and will continue to change. One of those changes that many, if not all growers, have experienced is how to deal with weed resistance. ...

Peanut cultivar response to damage from tobacco thrips and paraquat
Virginia market-type peanut cultivars in North Carolina vary in the number of days following emergence required to reach optimum maturity, and concern over cultivar response to interactions of tobacco thrips (Frankliniella fusca Hinds) damage in absence of in-furrow insecticide and injury from paraquat exist with respect to cultivar selection. Experiments were conducted during 2007 and 2008 to ...

Controlling Barnyardgrass with Corn Hybrid Selection
Barnyardgrass is a summer annual grass weed with a global impact on corn production. Yield losses due to barnyardgrass competition have been estimated up to 45% or more for crops such as cotton and corn. Besides corn, it can also be a serious weed pest in rice, soybean, sugarbeet, cotton, and corn. Integrated weed management techniques can be used for control of barnyardgrass in corn. High ...

Look to Ag leader to help you comply with new Dicamba rules and regulations
Sometimes, rules and regulations come along to change how you manage your farm. The federal government’s recent action on the common herbicide ingredient dicamba is one such example, and resilient farmers may need to make some changes to comply with new regulations laid out by the U.S. Environmental Protection Agency (EPA) in October 2017. That’s when EPA ruled that three crop ...
