Impact of cultural practices on two‐spotted spider mite (Tetranychus urticae Koch) infestation in tomato cultivation in the Central Rift Valley of Ethiopia

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

Developing and deploying an unmanned aerial system–based phenotyping program for maturity to support soybean breeding

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Soybean [Glycine max (L.) Merr.] varieties are categorized into different relative maturity groups (MGs) that correspond to the approximate region that the variety is best adapted. Maturity is an important trait that growers consider when deciding which varieties to plant and for breeders as a covariate to compare genotypes.

Pixel‐level supervision resolves overlap: Benchmarking YOLOv12 segmentation for accurate multi‐cluster dry bean stand counting from time series unoccupied aerial systems imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract An agronomic trait such as stand count is important for cultivar development and crop management practices. Manually counting the number of plants is time consuming, labor‐intensive, and prone to error. The use of unoccupied aerial systems (UAS)‐collected red, green, blue (RGB) imagery in conjunction with advanced deep learning and image ...

Defoliation reconsidered?

open access: yes, 2015
Since the 1980s defoliation (often assessed by means of crown transparency) is the most used indicator of tree condition adopted in Europe. It has been criticized for its subjectivity and scarce relation with meaningful endpoints. Here we collated the results of three different studies carried out in France and Italy to investigate the relationship ...

Resistance sources to common bacterial blight and angular leaf spot of large speckled common bean genotypes in Southern Ethiopia

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract The common bean (Phaseolus vulgaris L.) is one of the most important legume crops in Ethiopia due to its versatility and adaptability. The common bean is significantly affected by major diseases, including common bean bacterial blight and angular leaf spot.

Effect of Phosphate Fertilization and Cutting Date Improves Nutritional Status and Productive Parameters of a Tropical Forage Legume

open access: yesLegume Science, Volume 8, Issue 3, September 2026.
ABSTRACT The use of chemical fertilizers is economically and environmentally costly to produce and apply. Therefore, optimized fertilizer use is critical to increase or maintain crop yields. We evaluated the productive and nutritional characteristics of the Stylosanthes cv “Campo Grande” submitted to different cutting date and phosphate fertilization ...

Population Dynamics of Greenhouse Thrips (Heliothrips haemorrhoidalis) on Avocado Under Single and Combined Predator Releases

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.
The greenhouse thrips, Heliothrips haemorrhoidalis (Bouché, 1833), is an important avocado pest in New Zealand, where repeated infestations reduce leaf quality and tree vigour. To assess biological control stability under different predator assemblages, this study evaluated thrips population dynamics and predator survival across two sequential phases ...

Assessing the Distribution, Density and Ecological Impacts of Feral Deer in Urban and Peri‐Urban Areas of Lake Macquarie, New South Wales, Australia

open access: yesEcological Management &Restoration, Volume 27, Issue 3, September 2026.
ABSTRACT Feral deer are associated with a range of environmental impacts including overgrazing and trampling of native vegetation, increased insolation, ringbarking, creation of wallows, erosion and stream degradation. Consequences of invasive deer impacts can threaten vulnerable ecological communities and have the potential to alter long‐term ...

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery

open access: yesPlant, Cell &Environment, Volume 49, Issue 9, Page 6931-6943, September 2026.
ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.
