Evaluation of Benzobicyclon for use in Midsouthern Rice (Oryza sativa) Systems
… compatible tank-mix partners, and rotational crop safety. It is recommended to apply benzobicyclon into a continuous flood system. Japonica cultivars exhibited excellent crop safety to benzobicyclon, while indica cultivars showed high levels of sensitivity to the herbicide. Benzobicyclon …

Screening of herbicides for selective weed control in African marigold (Tagetes erecta)
… and trifluralin, had an acceptable margin of crop safety both in the greenhouse and in the field when applied at one, two, and four times their labeled rates. Two postemergence herbicides, topramezone and encapsulated acetochlor, caused minimal visual injury to the crop and encapsulated …

Molecular and pathological differentiation of colletotrichum truncatum from scentless chamomile and legume crops
… pathogen on lentil, raising questions about crop safety. Ribosomal DNA (rDNA) internal transcribed space (ITS) regions of C. truncatum isolates collected from different plant hosts were examined, and compared with additional Colletotrichum species. Sequences were amplified with the universal …

Evaluation of Benzobicyclon in Midsouth Rice (Oryza sativa) Production Systems
… herbicide applications without also damaging the crop. Hence, there is a need for a new effective postemergence weedy rice control herbicide. Findings from this research indicate that the use of benzobicyclon in current standard quizalofop- and imidazolinone-resistant rice herbicide programs …

Preemergence activity of chloroacetamide herbicides on a multiple herbicide-resistant population of waterhemp (amaranthus tuberculatus)
… weeds when applied PRE, and relatively high crop safety. Waterhemp [Amaranthus tuberculatus (Moq.) Sauer] is a small-seeded, summer annual weed species native to the Midwest. Waterhemp is dioecious with an ability to evolve resistance to herbicides from various sites-of-action. This, paired …

Industrial Hemp (Cannabis sativa L.) Germination Temperatures and Herbicide Tolerance Screening
… predicted hemp would be the first billion dollar crop given its multiple industrial applications. Government policy that restricted, then prohibited, hemp's use in the U.S. prevented that from happening. A reawakening to the versatility and usefulness of hemp for products ranging from engineering …

Weathering of sulfide ores in model soils, potentially toxic element release and bioavailability
… transport, subsequently contaminating soils and crops used to support human populations. The importance of these particles, as sources and influencers of PTE biogeochemistry in productive soils, has received limited research. Long-term (365 d) batch incubation experiments, field weathering …

Evaluation of Fenclorim Safener for Use in Rice with Group 15 Herbicides
… for Arkansas rice production, but variable crop tolerance has been observed. Additionally, acetochlor at 1,260 g ai ha-1 elicited less rice injury when seeds were treated with a herbicide safener seed treatment of fenclorim at 2.5 g ai kg-1 of seed relative to without the fenclorim seed …
