A wild population of a plant species, especially a cross-pollinated species, can display considerable genetic variation. Genetic variability is evident in differential susceptibility to an herbicide because the population can show continuous phenotypic variation. Recent, recurrent selection studies have revealed that phenotypic variation in response to low herbicide rates is heritable and can r...

The integration of pre-emergence (PRE) herbicides is an important component sustainable long-term weed management programs in soybean [Glycine max (L.) Merr.]. objective this study was to evaluate the efficacy 11 PRE on residual control soybean. Field experiments were conducted 2018 and 2019 at Arlington Lancaster, WI. Herbicide treatments consisted imazethapyr, chlorimuron-ethyl, cloransulam-m...

In the last years the chloro-s-triazine active substance terbuthylazine has been increasingly used as an herbicide and may leave residues in the environment which can be of concern. The present study aimed at developing a bioaugmentation tool based on the soil bacterium Arthrobacter aurescens strain TC1 for the remediation of terbuthylazine contaminated soils and at examining its efficacy for b...

Weed science has contributed much to agriculture, forestry and natural resource management during its history. However, if it is to remain relevant as a scientific discipline, it is long past time for weed scientists to move beyond a dominating focus on herbicide efficacy testing and address the basic science underlying complex issues in vegetation management at many levels of biological organi...

To study the long-term usefulness of genetically-modified agriculture via herbicide-tolerant crops, a simulation model is built by focusing on the fundamental environmental feedback mechanisms. The most critical mechanism is the evolution of resistance in weeds via natural selection. Agricultural sustainability is investigated under different policies and scenarios, in comparison with conventio...

In order to investigate physiological and biochemical changes of wheat under stress residue of Imazethapyr herbicide (Imazethapyr), an experiment was conducted in a completely randomized design with four replications in greenhouse conditions at university of Mohaghegh Ardebili. The treatments consisted of five dose levels of herbicide Imazethapyr (0, 0.011, 0.022, 0.033 and 0.044 micrograms of ...

This study was conducted to compare Zest (nicosulfuron) herbicide at two rates and application timings for efficacy in grain sorghum. Palmer amaranth control best when a preemergence (PRE) followed by late postemergence (LPOST) treatment. 0.67 or 1.33 oz/a provided the velvetleaf shattercane control. Either rate of applied early (EPOST) controlled green foxtail more than 90%, but higher require...
