Improving access to new technologies: An experiment with Kenyan input sellers

American Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Residue Analysis of Herbicide Sethoxydim

Journal of Pesticide Science, 1987
An analytical method for the residue of sethoxydim [(±)2-(1-ethoxyiminobutyl)-5-[2-(ethylthio) propyl]-3-hydroxycyclohex-2-enone, STM] in crops was established using high-performance liquid chromatograph (HPLC). A chopped sample was extracted with 50% aqueous methanol (including 5% Na2S2O3) and STM was transferred to n-hexane.

Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics

American Journal of Botany, EarlyView.
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

Glyphosate-based herbicide formulations and reproductive toxicity in animals

Veterinary and Animal Science, 2020
The adoption of genetically engineered (GE) crops in agriculture has increased dramatically over the last few decades. Among the transgenic plants, those tolerant to the herbicide glyphosate are among the most common.

Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

Applications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Herbicide residues in California agricultural soils

California Agriculture, 1968
The question of herbicide residues, and possible effects on succeeding crops, is one of great importance to agriculture, particularly with increasing use of such chemicals to minimize hand labor requirements as well as soil compaction from weed ...

Understanding the structural basis of ALS mutations associated with resistance to sulfonylurea in wheat

Scientific Reports
Developing herbicide-tolerant wheat varieties is highly desirable for effective weed management and improved crop yield. The enzyme acetolactate synthase (ALS) is the target enzyme for the sulfonylurea class of herbicides.
