Behavior of and Crop Injury Induced by Native and Exotic Stink Bugs in Mid-Atlantic Soybean
… weeks using small cages in a field of double crop soybean at sites in Virginia, Maryland, and Delaware during 2007-2009. Large field cages were infested by an introduced species for two weeks in 2010-2011. Results showed that Euschistus servus Say and Acrosternum hilare Say adults or nymphs …

Influence of Several Herbicides on Visual Injury, Leaf Area Index, and Yield of Glyphosate-Tolerant Soybean <I>(Glycine max)</I>
… in 1999 and 2000 to investigate potential crop injury from several herbicides on glyphosate-tolerant soybean, and to determine the relationship between soybean maturity, planting date, and herbicide treatment on soybean injury, leaf area index (LAI), and yield. Three glyphosate-tolerant …

Evaluation of Weed Control and Crop Tolerance With Postemergence Herbicides in Sethoxydim-Tolerant Corn
… and sethoxydim, and method of application, on crop tolerance and bermudagrass (Cynodon dactylon L.) control; to evaluate the effect of sethoxydim in combination with broadleaf herbicides on crop tolerance and bermudagrass control; to evaluate sethoxydim-based herbicide programs for annual grass …

Field efficacy and availability, movement, and persistence of ICIA-0051 herbicide in soils
… organic matter. Regardless of the rate used, crop injury decreased over time, although the highest rate (1 ppm of ICIA-0051) showed significant crop injury even after 6 months in several soils in the greenhouse studies.

Weed Control in Cucumber Cucumis sativus, Pumpkin Cucurbita maxima, and Summer Squash Cucurbita pepo with Halosulfuron
… (Cucurbita pepo L.) are economically important crops in Virginia. Only a few herbicides are registered for weed control in these crops. Halosulfuron is a sulfonylurea herbicide which controls several broadleaf weeds and yellow nutsedge (Cyperus esculentus L.). Cucurbit crops have some tolerance …

Incorporating the Experimental Herbicide CGA 362622 into Cotton Weed Management Programs in Virginia
… of cotton (Gossypium hirsutum L.) to Virginia crop growers has 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 …

Herbicide safeners: upregulating detoxification mechanisms for selective weed management in grain sorghum (Sorghum bicolor L. Moench)
… L. Moench) is one of the world’s most important crops based on area sown and production. Sorghum utilizes C4 photosynthesis and is one of the most efficient crops for water usage and solar energy conversion. It is grown for human consumption, animal feed, and fuel worldwide. Originating in the …

The Impact of Herbicide-Resistant Rice and Hybrid Rice Technology on Weedy Rice Evolution
… rice in the field than inbred rice. Fields with cropping history of hybrid rice had higher volunteer rice infestation (20%) than fields planted only with inbred rice (5.6%). The total grain yield of rice was reduced by 0.4% for every 1% increase in volunteer rice density, averaged over cultivars. …

Evaluation of Topramezone for Use in Rice (Oryza sativa L.) Production
… one of the most problematic weeds in rice cropping systems, alone has been found to be resistant to four herbicide sites of action (SOA) in certain populations, leaving growers no options for control. This unsettling fact has led to research on other SOAs that have not previously been used …

Evaluation And Characterization of Herbicide Resistance In Italian Ryegrass (Lolium multiflorum Lam.) Biotypes To Diclofop-methyl And Alternative Management Options
… of biotypes previously exposed to diclofop in a cropping situation were adequately controlled versus 94% of the biotypes not previously treated with diclofop. Tralkoxydim provided the most effective control of four of the biotypes. No postemergence treatment effectively controlled one biotype …

Uptake, translocation, and metabolism 2,4-D in enlist crops and control of drought-stressed waterhemp (Amaranthus tuberculatus) with 2,4-D and glyphosate
… levels, reactive oxygen species, cell membrane injury, and ultimately plant death. Selectivity of 2,4-D is derived from metabolism differences between monocots and dicots. Until recently, 2,4-D could not be used in dicot crops like soybean (Glycine max) and cotton (Gossypium hirsutum); however, …
