Market regulation and productivity: The case of the Canadian Wheat Board

American Journal of Agricultural Economics, EarlyView.
Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

Corn tolerance to florpyrauxifen-benzyl rates and its mixture with atrazine and mesotrione

Frontiers in Agronomy
Florpyrauxifen-benzyl is a new synthetic auxin herbicide labeled in rice with a broad spectrum of control, typically more potent on broadleaf weeds. It has garnered some interest as a potential broadleaf weed control option for use in corn at low rates ...

Comparative Toxicity of Bordeaux Mixture by Ingestion and Cuticular Contact Under Climate Change Conditions on Trichogramma cordubensis

Entomologia Experimentalis et Applicata, EarlyView.
In the face of environmental contamination to copper, mainly resulting from frequent copper‐based fungicide applications, it is crucial to understand the side effects of these pesticides on non‐target organisms to improve pest management. Trichogramma cordubensis, used as a biological control agent against grape berry moths in vineyards, shows strongly

Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

Entomologia Experimentalis et Applicata, EarlyView.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...
