The foliar pathogens of wheat, particularly Zymoseptoria tritici and Pyrenophora tritici-repentis, represent a significant threat to yield. We used a SEIR (Susceptible–Exposed–Infected–Removed) model to quantify epidemic dynamics based on different ...

Meadow birds on organic and conventional arable farms in the Netherlands: abundance and nest success [PDF]
Intensification of agriculture is mentioned to be the key drive behind the decline of farmland birds on grassland and on arable land. This raises the question whether a less intensive system, such as organic, can stop or reverse these declines.

Bioenhancer‐Driven Modulation of Membrane Dynamics Improves B‐Vitamin Uptake in Caco‐2 Cells
Natural bioenhancers such as extracts from ginger, turmeric, black pepper, and spearmint increase the uptake of vitamins B1, B5, B6, and B7 in Caco‐2 cells. Micellized formulations further increase efficacy. These findings indicate that altered membrane fluidity contributes to enhanced cellular absorption, providing a new route to improve vitamin B ...

Farmers worldwide use agrochemicals and biological inputs to fertilize fields, manage pests and diseases, and promote plant growth. However, there is still limited field-based evidence on the extent to which biological inputs function as substitutes ...

Rosemaund Pesticide Transport Study 1987-1993 [PDF]
This report comprised the results, conclusions and recommendations of a project in the early 1990s to study the pesticide concentrations in soil and water that resulted from normal use of agrochemicals on arable crops at a farm in the Rosemaund catchment.

ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Explaining Productivity Variation among Smallholder Maize Farmers in Tanzania [PDF]
Using a stochastic frontier production model proposed by Battese and Coelli (1995), the paper estimates the levels of technical efficiency of 233 smallholder maize farmers in Tanzania and provides an empirical analysis of the determinants of inefficiency

This work presents a pH‐responsive ON–OFF fluorescent system based on a novel pyranoflavylium dye functionalized with a boronic acid receptor. The receptor exhibits a markedly higher affinity for the catechol‐containing polyphenol (+)‐catechin than for conventional diol‐rich molecules such as glucose and lactic acid.

Insights on the Use of Pesticides in Two Main Food-Supplier Coastal Valleys of Lima City, Peru
The food security of Lima—Peru’s capital city, which shelters over 30% of the total country’s population—depends on the food production of its nearest agricultural areas, the Chancay-Huaral and Chillón valleys, wherein agrochemicals are widely used. This

Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.
