Tifdwarf bermudagrass (Cynodon sp. (L.) Pers.) sod-plugs were treated with two rates of five herbicides (DCPA, Benefin, Bensulide, Terbutol and Kerb) to determine effects of these chemicals on shoot and root growth. Ap plication rates were those commonly used for weed control and twice this recommended rate. Herbicides were applied on top of the sod and below the sod to simulate surface treatme...

Limited information is available on control of broadleaf weeds in barley and response of barley cultivars to herbicides. Field experiments were conducted from 2007 to 2009 to evaluate post-emergence herbicides for control of broadleaf weeds in four barley cultivars. Herbicide treatments included 2,4-D sodium salt at 500 g ai ha 1, carfentrazone-ethyl at three rates (15, 20 and 25 g ai ha 1), an...

The most striking response of light-grown wheat seedlings to sublethal doses (0.1 m) of the herbicide Sirmate (3,4-dichlorobenzyl methylcarbamate) was the formation of achlorophyllous leaves. This herbicide did not inhibit seed germination and the leaves emerged normally, except that they had a bleached appearance. After 9 days, these plants died, presumably of starvation due to depletionofendo...

A series of novel methyl (R)-N-benzoyl/dichloroacetyl-thiazolidine-4-carboxylates were designed by active substructure combination. The title compounds were synthesized using a one-pot route from l-cysteine methyl ester hydrochloride, acyl chloride, and ketones. All compounds were characterized by IR, ¹H NMR, 13C NMR, and HRMS. The structure of 4q was determined by X-ray crystallography. The bi...

Bentazone is a broadleaf post-emergence herbicide widely used for crop production that inhibits photosynthetic activity, resulting in phytotoxicity and injury plants. Evaluating identifying herbicide-tolerant genotypes critical step plant breeding programs. In this study, we determined the reaction of 138 Korean soybean cultivars to bentazone using visual evaluation, selected were further evalu...

The herbicide, pendimethalin, is used worldwide, but its acute toxicity is not yet widely known. There have been some reported acute pendimethalin poisoning cases in humans and most of them intentionally ingested the concentrated formulation. We describe a 73-year-old man who developed corrosive gastroduodenal injury after accidental ingestion of the diluted (300 times with water) pendimethalin...

Paraquat is a potent herbicide of lethal toxicity. Its injury mechanism is attributed to the generation of very-reactive oxygen species, such as superoxide radicals, through which multiple injuries are produced on mucosa, although there have been no reports of injuries on the trachea. We describe a case of fatal paraquat poisoning with tracheal injuries, where the clinical debut was acute respi...

Ronstar® herbicide is one of the most effective preemergent herbicides available to professional turf managers. Unfortunately, in the South, it can sometimes be difficult to apply granular fertilizer plus Ronstar® products without causing injury to the turf. Tire tracking, discoloration and thinning turf are all symptoms that can be encountered when it is applied during the growing season, espe...

Efficient herbicide absorption and translocation, satisfactory weed control can be affected by the site of application. However, during harvesting crops previous soybean sowing, cutting process made harvesters on fleabane may generate a difficult management in pre sowing crop limiting leaf area herbicide. Experiments were conducted to evaluate efficiency translocation potential saflufenacil pla...
