Time-dependent adsorption of imazethapyr to soil

Weed Science, 2000
Abstract Time-dependent adsorption of imazethapyr was studied in the laboratory on a sandy loam soil at 16% moisture for 30 d. Soil pH was adjusted to 4.5 to 6.8. Concentration of imazethapyr in soil water declined rapidly within the first day of incubation for all soil pH levels, indicating rapid initial adsorption.

Maize cultivars differ in tolerance to imazethapyr

South African Journal of Plant and Soil, 2000
The low tolerance of maize (Zea mays L.) to imazethapyr ((±)-2-[4,5-dihydro-4 methyl-4-(1 -methylethyl)-5-oxo 1H-imidazol-2-yl]-5-ethyl-3-pyridinecarboxylic acid) resulted in extensive crop damage in 1992/93 due to residue carry-over from resistant soybean (Glycine max L.).

Spatial variability of imazethapyr sorption in soil

Weed Science, 1999
A significant limitation in using sorption coefficients (Kd) to predict solute transport through natural soils is the spatial variability of soil properties over large field areas. Spatial variability inKdfor imazethapyr was determined on representative samples from a 31.4-ha field, covering a pH range from 4.9 to 7.6 and an organic carbon (OC) range ...

Carryover of Imazethapyr and Imazapic to Nontolerant Rice

Weed Technology, 2010
The present work aimed to evaluate plant injury caused by residues in the soil of the formulated mixture of imazethapyr and imazapic to a nontolerant genotype of rice (IRGA 417) drilled at 371 and 705 d after herbicide application (DAA). Herbicide carryover reduced up to 55% of the grain yield of the IRGA 417 drilled at 371 DAA, and plant injury was ...

EVALUATION OF IMAZETHAPYR FOR WEED MANAGEMENT IN CHICKPEA

Plant Archives
A field experiment was carried out at the Agricultural Farm, Palli Siksha Bhavana, Visva-Bharati, during the rabi season of 2020-21 to investigate the impact of imazethapyr in chickpea weed management. The experiment was carried out in a randomized block design, which contains nine treatments and three replications. The treatments include, pre and post

Availability and Persistence of Imazaquin, Imazethapyr, and Clomazone in Soil

Weed Science, 1989
The availability and persistence of imazaquin, imazethapyr, and clomazone were studied in a Cisne silt loam (1.3% organic matter) and a Drummer silty clay loam (5.8% organic matter). Availability of all three herbicides to bioassay species was greater in the Cisne soil than in the Drummer soil.

Imidazolinone-Tolerant Rice Response to Imazethapyr Application

Weed Technology, 2006
Greenhouse research was conducted to evaluate shoot and root growth response of imidazolinone-tolerant (IT) rice cultivars to imazethapyr applied postemergence at various rates and application timings. Imazethapyr was applied at 70, 140, and 280 g ai/ha to IT cultivars ‘CL 121’ and ‘CL 161’ in the one- to two-leaf and three- to four-leaf growth stages.

Selection for resistance to the herbicide imazethapyr in somaclones of soyabean

Weed Research, 2001
Cultivars of soyabean [Glycine max (L.) Merr.] resistant to the herbicide imazethapyr were identified by suspending the roots of 5‐day‐old seedlings in nutrient culture containing 2.5 mg a.i. L–1 imazethapyr and then comparing the inhibitory effect on root length and shoot dry weight.

Interaction of glyphosate with chlorimuron, fomesafen, imazethapyr, and sulfentrazone

Weed Science, 1998
Field experiments were conducted on eight weed species to determine if chlorimuron, fomesafen, imazethapyr, or sulfentrazone at two rates (labeled and one-half the labeled rate) were complementary tank mixtures with glyphosate at 210 and 420 g ai ha−1.

Petroleum Oil and Emulsifier Affect the Phytotoxicity of Imazethapyr

Weed Technology, 1992
Six commercial petroleum oil (PO) adjuvants differed in their enhancement of imazethapyr phytotoxicity to green foxtail and kochia but not to redroot pigweed, when imazethapyr was applied postemergence at 17 g ha–1. Imazethapyr at 5 g ha–1plus 27 combinations of three oils and nine emulsifiers reduced kochia growth by 61 to 88%.
