Detection of multi-tomato leaf diseases (late blight, target and bacterial spots) in different stages by using a spectral-based sensor. [PDF]
Several diseases have threatened tomato production in Florida, resulting in large losses, especially in fresh markets. In this study, a high-resolution portable spectral sensor was used to investigate the feasibility of detecting multi-diseased tomato ...

Foliar diagnosis as a guide to olive fertilization
A long term experiment was established in olive orchards of Andalusia, southern Spain, to compare the fertilization practice based on foliar diagnosis versus the current fertilization practice in the area. Only nutrients whose concentration in leaves taken in July were below the critical levels were applied in the former treatment, whereas in the ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Study on the curative and eradicant action of fungicide combinations to control late blight in potato [PDF]
Commercial fungicide combinations were tested in the field for efficacy on foliar late blight caused by Phytophthora infestans in substitution of tin. When the first disease symptoms appeared, the tested fungicide treatments for late blight control were ...

Fungal disease management in cotton using plant protection products: An Australian perspective
Cotton disease management requires evidence‐driven use of plant protection products. Progress hinges on integrating chemistry, diagnostics, stewardship and sustainability to build resilient production systems. Abstract Cotton production faces persistent challenges from pathogens that compromise plant establishment, yield, and fibre quality.
