Invasion of a Virulent Phytophthora infestans Genotype at the Landscape Level; Does Spatial Heterogeneity Matter? [PDF]

open access: yes
Proper landscape-scale deployment of disease resistant genotypes of agricultural crop species could make those crops less vulnerable to invasion by resistance breaking genotypes.

Strategien zur Reduzierung der Kupferaufwandmengen im ökologischen Kartoffelanbau – Projekt “ÖKO-SIMPHYT“ [PDF]

open access: yes, 2007
Potato late blight (Phytophthora infestans) is still an unsolved problem in organic farming. Up to now the disease can only be controlled by copper fungicides.

Dynamics of Fiscal Habits and Soft Budgets in Federations

open access: yesJournal of Public Economic Theory, Volume 28, Issue 2, April 2026.
ABSTRACT In this paper, we are motivated by empirical evidence of persistent, implicit or explicit, bailouts in federations from high‐tier (e.g., center) governments to low‐tier (e.g., state) governments. We build a novel dynamic model for a federation containing N ≥ 2 $N\ge 2$ identical regional governments and a central government.

Entanglement of plant immunity and endomembrane trafficking revealed by plant–powdery mildew fungal interactions

open access: yesNew Phytologist, Volume 250, Issue 2, Page 799-804, April 2026.
Summary Plant immunity is complex, and studies of leaf epidermal cells attacked by powdery mildew fungi have been instrumental in revealing how it relies on plant endomembrane trafficking. Immunity against these biotrophic fungi is manifested as cell wall deposits (‘papillae’) and the hypersensitive reaction (HR), both involving plant endomembrane ...

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

GROWING OF THE ORGANIC POTATOES WITH USING OF THE MULCHING MATERIALS [PDF]

open access: yes, 2010
Mulching which has become more popular lately is an important way of soil protection in the plant production. Mulching massively reduces soil erosion [DÖRING ET AL., 2005], virus vector in seed potatoes [DÖRING ET AL., 2006] and it may also act as a tool
