Host resistance modulates in planta efficacy of seed‐applied fluxapyroxad against spot form net blotch in barley

Pest Management Science, EarlyView.
Barley variety influences fluxapyroxad efficacy by affecting distribution and dissipation of the active ingredient, with plant biomass contributing to these differences. Abstract BACKGROUND Seed‐applied fungicides are used to protect barley seedlings from spot form net blotch, caused by Pyrenophora teres f. maculata, among other diseases.

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

Pest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

Clostridium difficile spore biology: sporulation, germination, and spore structural proteins

Trends in Microbiology, 2014
Clostridium difficile is a Gram-positive, spore-forming obligate anaerobe and a major nosocomial pathogen of world-wide concern. Due to its strict anaerobic requirements, the infectious and transmissible morphotype is the dormant spore.

Germination of Helminthostachys Spores

American Fern Journal, 1987
For nearly a century the spores of the Ophioglossaceae have been sown, but few investigators have succeeded in germinating them (Boullard, 1963). Campbell (1895, 1907) was the most successful in germinating spores of the Ophioglossaceae on soil. He reported the early stages of germination of spores of Botrychium virginianum (Campbell, 1895) and of ...

Presence and abundance of airborne Botryosphaeriaceae conidia are governed by temperature and season in the Okanagan Valley, Canada

Pest Management Science, EarlyView.
Presence and abundance of Botryosphaeria dieback inoculum were determined using spore trapping and droplet digital polymerase chain reaction in British Columbia, Canada. Highest inoculum was recorded in spring (April–June) and again in summer (July–September). These results suggest early pruning in December–January can mitigate pruning wound infections.

Absorption and translocation of 14C‐propiconazole associated with two adjuvants in young coffee plants

Pest Management Science, EarlyView.
Experimental workflow evaluating 14C‐propiconazole absorption and translocation in Coffea arabica with two biodegradable adjuvants, quantified at six post‐application time points using radioscanner and liquid scintillation spectrometry. Abstract BACKGROUND This study evaluated the absorption, translocation and distribution of 14C‐propiconazole applied ...

In planta fluxapyroxad gradients from seed treatment differentially select fungicide‐sensitive and reduced‐sensitive genotypes of Pyrenophora teres f. maculata

Pest Management Science, EarlyView.
Spatial concentration gradients of seed‐applied fluxapyroxad within barley create heterogeneous exposure environments, driving differential suppression of succinate dehydrogenase inhibitor‐sensitive Pyrenophora teres f. maculata isolates and enrichment of reduced‐sensitive genotypes, thereby shaping within‐host fungicide resistance selection dynamics ...

Canonical germinant receptor is dispensable for spore germination in Clostridium botulinum group II strain NCTC 11219

Scientific Reports, 2017
Clostridium botulinum is an anaerobic sporeforming bacterium that is notorious for producing a potent neurotoxin. Spores of C. botulinum can survive mild food processing treatments and subsequently germinate, multiply, produce toxin and cause botulism ...

Effectiveness of model‐based decision tools for disease control in wheat, potato and grapevine: a multilevel meta‐analysis

Pest Management Science, EarlyView.
Meta‐analysis results indicate that decision tools can provide effective disease control, although their performance may vary among crops. Despite differences, decision tools reduced the Treatment Frequency Index across three crops. Abstract BACKGROUND A multilevel meta‐analysis was conducted to provide further evidence on the benefits of decision ...
