Responses of selected chickpea cultivars to imidazolinone herbicide
… developed chickpea cultivars with resistance to imidazolinone (IMI) class of herbicides. The objectives of this study were: (i) to examine the reaction of four chickpea cultivars – CDC Luna, CDC Corinne, CDC Alma, and CDC Cory - to imazamox, imazethapyr, and a combination of imazamox and …

Combining ability for yeild of imidazolinone resistant maize inbred lines under artificial and natural striga infestation
… striga parasitism has been the use of imidazolinone resistant maize varieties where the seed is coated with imazapyr herbicide. A study was carried out to investigate the inheritance of this trait in maize populations. Ninety three testcrosses based on three testers; CML373- …

Growth Analyses and Patterns of Cross-Resistance in Four Imidazolinone-Resistant Smooth Pigweed (Amaranthus hybridus) Populations
… 1999 to: (1) evaluate the responses of one imidazolinone (IMI)-susceptible (S) and four -resistant (R1, R2, R3, and R4) smooth pigweed populations to various acetolactate synthase (ALS)-inhibiting herbicides, (2) determine the mechanism of resistance, and (3) evaluate the relative growth and …

Crop and herbicide rotation effects on weed population dynamics and the characterization of imidazolinone-resistant smooth pigweed (Amaranthus hybridus)
Shifts in weed populations to herbicide-resistant biotypes are occurring more frequently. In two adjacent field studies from 1991 through 1994, crop rotations and herbicide programs affected control and densities of common lambsquarters, common ragweed, smooth pigweed, redroot pigweed, jimsonweed, …

Physiological response of sulfonylurea-tolerant soybean to thifensulfuron and imazethapyr
… a sulfonylurea herbicide, and imazethapyr, an imidazolinone herbicide, inhibit acetolactate synthase (ALS) and used for weed management in soybean production. Tank mixing thifensulfuron with imazethapyr would provide an excellent weed control spectrum for soybean production in Illinois but …

Biology and Control of Eastern Black Nightshade, Palmer Amaranth, and Common Pokeweed, in No-Till Systems on the Eastern Shore Regions of Virginia and Maryland
… family, but controlled with herbicides of the imidazolinone family. A population of Palmer amaranth was found to be glyphosate-resistant, but herbicide programs were identified that could control this biotype in soybean and corn systems. Experiments on the fate of glyphosate in common pokeweed …

Combination effect of ACP 2100, imazaquin and triclopyr on common dandelion and three Kentucky bluegrass turf types
The compatibility of ACP 2100, a member of the imidazolinone family (chemistry not released), imazaquin (2- [4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H̱-imidazol2- yl]-3-quinolinecarboxylic acid) and triclopyr {[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid} was investigated for use in a turf …

Evaluation of Benzobicyclon in Midsouth Rice (Oryza sativa) Production Systems
… in current standard quizalofop- and imidazolinone-resistant rice herbicide programs provides tremendous utility for Midsouth rice producers. In both of these production systems, the addition of benzobicyclon to the respective standard herbicide programs resulted in comparable or …

Characterization of Acetolactate Synthase-Inhibiting Herbicide-Resistant Smooth Pigweed and Corn Weed Management Programs Utilizing Mesotrione in Combinations with Other Herbicides
… of ALS-inhibiting herbicides that included imidazolinone (IMI), sulfonylurea (SU), pyrimidinylthiobenzoate (PTB), and triazolopyrimidine sulfonanilide (TP) chemistries. Transformation of this smooth pigweed ALS gene into <i>Arabidopsis thaliana</i> confirmed that the Asp<sub>376</sub> …

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>)
… to investigate growth and seed production of one imidazolinone-susceptible (S) and five -resistant (R1, R2, R3, R4, and R5) smooth pigweed biotypes. Although the S biotype produced more total biomass than four of the five R biotypes, R4 displayed a more rapid growth rate at 3 to 5 wk after …
