Optimizing Weed Management via Microwave Irradiation
One potential alternative to chemical weed control is the use of microwave radiation, a particular form of indirect thermal weeding. Absorption of microwave radiation causes water molecules within the tissue to oscillate, thereby converting electromagnetic energy into heat. This technique is rapid, …

Weed management in early-planted Illinois soybean
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Weed management practice selection among Midwest U.S. organic growers
Weeds are the most costly of all agricultural pests, reducing crop yields, quality and harvestability while simultaneously increasing management expenses. Restriction of synthetic herbicide use in organic agricultural systems increases the complexity of weed management, leading organic farmers to …

Effects of Glyphosate on Weed Management and Reproductive Biology of Glyphosate-Resistant Corn
… from 2000 to 2002 to evaluate crop tolerance, weed control, grain yield, and net returns in glyphosate-resistant corn with various herbicide systems. Weed management systems evaluated various preemergence (PRE) and postemergence (POST) herbicide options. Glyphosate formulations did not …

Agronomic and Physiological Evaluation of Sethoxydim and Isoxaflutole for Weed Management in Corn
… base for new technologies available for weed management. This information is required to achieve a full understanding of how the technology can be optimized to benefit weed management systems as well as elucidate any negative attributes of the technology. This research has shown the …

Evaluation of integrated weed management techniques and their nuances in Virginia crop production
Herbicide resistant weeds are driving implementation of integrated weed management (IWM). A new tactic to manage weeds is harvest weed seed control (HWSC), which targets weed seeds retained on the plant at crop harvest and either destroys, removes, or concentrates them. Research is limited on the …

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 …

New Herbicide Strategies for Weed Management in Pumpkin and Soybean and Potato Vine Desiccation
Weed control and desiccation are routinely executed with herbicides. Potato vine desiccation facilitates harvest, improves skin set, and regulates tuber size. Saflufenacil, glufosinate, saflufenacil plus glufosinate, and carfentrazone plus glufosinate were compared to diquat applied at 43, 31, and …

Weed Management Programs in Potato, Transplanted Tomato and Transplanted Pepper with Rimsulfuron and Other Herbicides
Weed management programs in "Superior" potato with PRE and POST rimsulfuron treatments were investigated during 1992, 1993, and 1994. Common ragweed control by PRE combinations of metolachlor with linuron or metribuzin was higher when treatments included PRE or POST rimsulfuron. Common …

Weed management in conventional, no-till, and transgenic corn with mesotrione combinations and other herbicides
Weed management programs in corn typically include herbicides applied both preemergence (PRE) and postemergence (POST) for season-long weed control. Mesotrione is a new triketone herbicide registered for PRE and POST control of broadleaf weeds in corn. Triketone herbicides function through …

Harvest Weed Seed Control: An Integrated Weed Management Strategy for Organic and Conventional Production Systems
Harvest weed seed controls (HWSC) destroy weed seeds that are retained by the plant at crop harvest, which would typically be spread by the harvester along with other field residues. HWSC exploits coincidental maturity between crops and weeds, so an experiment was designed to collect weed seeds as …

Herbicide safeners: upregulating detoxification mechanisms for selective weed management in grain sorghum (Sorghum bicolor L. Moench)
… U.S. increasing over 20% from 2014. Controlling weeds selectively is one of the most significant challenges when producing grain sorghum. Growers are restricted to preemergence (PRE) and post emergence (POST) herbicides that typically target broadleaf weeds, but options for controlling grasses …

A gyomszabályozás lehetőségei és korlátai gyomirtószeres sárgarépa termesztési rendszerben = Possibilities and limits of weed management in herbicide free carrot production system
Az ökológiai növénytermesztés nem létezhet sikeres gyomirtás nélkül. A technológia hiányát felismerve kutatásom során célom volt: - vegyszermentes gyomszabályozási módszerek összegyűjtése és összevetése a nemzetközi szakirodalom alapján, - olyan gyomszabályozási stratégia kidolgozása, mely az …

Characterization of Acetolactate Synthase-Inhibiting Herbicide-Resistant Smooth Pigweed and Corn Weed Management Programs Utilizing Mesotrione in Combinations with Other Herbicides
… recent years has resulted in the selection of 89 weed species resistant to these herbicides. One management strategy that can eliminate or slow the development of resistance is applying mixtures of herbicides with different modes of action. This research involved the characterization of …

Evaluation of Weed Management and the Agronomic Utility of Cotton Grown on a 15-Inch Row Configuration and the Biology and Ecology of Doveweed
… Field experiments were conducted to evaluate weed management systems in glufosinate-resistant cotton planted in 38- and 97-cm rows. Greater than 90% control of annual grasses and Amaranthus spp. in 2004 and Ipomoea spp. in both years was obtained in narrow-row cotton receiving glufosinate …

Asexual Propagation of Four Cultivars of Vaccinium Corymbosum and Weed Management in an Established Orchard of Vaccinium Corymbosum 'Bluejay' (Highbush Blueberry) in South Central Kentucky
… well later in the season. The effects of four weed management schemes were investigated on berry yield components and new growth in an established orchard of 'Bluecrop' blueberries in Metcalfe County, Kentucky. The experimental design was a randomized complete block with four replications. …

Effect of Temperature and Chemical Additives on the Efficacy of the Herbicides Glufosinate and Glyphosate in Weed Management of Liberty-Link and Roundup-Ready Soybeans
… crops offers producers many more options for weed control systems. These crops allow environmentally safe, non-selective herbicides to be used as selective herbicides, broadening the spectrum of weeds controlled, while not harming the crop. As these crops are very new on the market, …

Herbicide-based Weed Management Systems for Potato (<i>Solanum tuberosum</i>) and Wheat (<i>Triticum aestivum</i>) and Growth and Reproductive Characteristics of Smooth Pigweed (<i>Amaranthus hybridus</i>)
Integrated weed management involves the utilization of weed biology principles to develop effective and economical control strategies. This research involved investigations of herbicide-based weed management programs in potato (<i>Solanum tuberosum</i> L.) and winter wheat (<i>Triticum aestivum</i> …
