Revisiting the Political Economy of Agriculture in 21st Century Food Systems

Journal of Agricultural Economics, EarlyView.
ABSTRACT In 1932, Joseph Duncan argued in the Journal of Agricultural Economics that agricultural economists should engage more explicitly with politics. Nearly a century later, the political economy of food and agriculture has expanded in both scope and complexity.

Multiple Resistance of Horseweed to Glyphosate and Paraquat and Its Control with Paraquat and Metribuzin Combinations

Agronomy, 2012
Greenhouse and field studies were conducted in 2007 and 2008 to investigate possible multiple-resistance of horseweed to paraquat and glyphosate, and to evaluate the effect of the addition of metribuzin to paraquat on control of paraquat-resistant ...

Smart double‐screening system of propagating male‐sterile lines for maize hybrid seed production

Journal of Integrative Plant Biology, EarlyView.
The Seed and Seedling Marker Method double‐screening system for maize hybrid seed production integrates Ms45‐mediated fertility restoration, Mn1/Sh1‐RNAi‐based seed selection, and Lc‐based seedling selection. It thus enables efficient, high‐purity propagation of male‐sterile lines by combining fertility maintenance with sequential visual selection at ...

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Differential Resistance Mechanisms to Glyphosate Result in Fitness Cost for Lolium perenne and L. multiflorum

Frontiers in Plant Science, 2017
Multiple mechanisms of resistance to glyphosate are exhibited by populations of Lolium spp. worldwide. Association of resistance with growth and reproductive fitness is an important predictor for long-term success of glyphosate-resistant (R) versus ...

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry

Journal of Agrarian Change, EarlyView.
ABSTRACT The global pesticide industry transformed from one dominated by patented products and legacy multinationals with strong manufacturing bases in the United States and EU to one dominated by generic products produced in India and China. We use proprietary market research data, data from regulatory filings, industry press and bilateral trade data ...

Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers
