Can outsourcing pest and disease control help reduce pesticide expenditure? Evidence from rice farmers

Agribusiness, EarlyView.
Abstract Outsourcing pest and disease control (PDC) has grown rapidly worldwide, especially in developing countries. Although numerous studies have investigated various advantages of outsourcing PDC, little is known about its impact on pesticide expenditure.

Flower color variation in Digitalis purpurea: Pollination and soil influences across native and introduced populations

American Journal of Botany, EarlyView.
Abstract Premise Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia.

Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Learning from fungicide resistance

Transactions - British Mycological Society
Crop protection against fungal pathogens is essential to prevent crop losses and maintain food security. Current crop protection relies heavily on chemical fungicides. However, rapid evolution of fungicide resistance, the constant appearance of new pathogens, and legislation against chemical pesticides due to concerns regarding their impact on human ...

Tannin resin-boron associations: Leaching and biological resistance [PDF]

, 2012
The easy leaching of boron in wood preservation formulations has allowed to use this fungicide only for short term applications. The recently discovered adduct with flavonoids allows boron to resist longer periods of time within wood and consequently ...

Early Detection of Fungicide Resistance Through Sensitivity Testing of Various Fungicide Active Ingredients and Genetic Variation of Downy Mildew-Causing Peronosclerospora maydis from Maize (Corn) Production Centers in Java, Indonesia

AGRIVITA Journal of Agricultural Science
Maize downy mildew disease in Java, caused by Peronosclerospora maydis, can cause yield losses of up to 100%. Disease management of downy mildew using synthetic fungicides has been reported to cause resistance to P. maydis.
