The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Journal of Field Robotics, EarlyView.ABSTRACT The architecture of apple orchards can be converted to easier operation by implementing the use of a low‐cost, tractor‐mounted, dual manipulator based on a robotic harvesting system with lower degrees of freedom (DoF). To accurately avoid injuries by detecting apples, an efferent, real‐time vision system that includes a new gripping mechanism ...

Pollination success in apples is dependent upon wild bees and orchard design
Journal of Pollination EcologyInsect pollinators are important drivers of fruit quality and yield in horticultural systems. The global reduction in wild bee populations has increased the demand for managed honeybees, despite honeybees relatively low pollination efficiency.

Robotics for Crop Pollination: Recent Advances and Future Direction
Journal of Field Robotics, EarlyView.ABSTRACT There is great interest in alternative pollination strategies for crop production in the face of climate change and perennial threats to the traditional pollination mechanisms. This review explores the potential of robotic pollination as a promising solution to these challenges affecting crop fertilization, agricultural sustainability, and ...

Arthropods on Abandoned Apple Trees: Comparison of Orchard Versus Alley
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016 Occurrence of arthropods on abandoned apple trees was studied in 2010 and 2011. The research was carried out in South Moravia (Czech Republic). Two sites were selected within this area – apple trees (Malus domestica) in an alley along a road and an ...

INVESTMENT ANALYSIS OF ALTERNATIVE FRUIT TREE SPRAYERS IN MICHIGAN ORCHARDS [PDF]
Changing orchard sprayer technology and rising pesticide costs to fruit growers raise the need to analyze the profitability of alternative sprayer investments. This study analyzes investments in four orchard sprayers for use in Michigan apple production:

How Passive Acoustic and Traditional Monitoring Estimate Bird Diversity Across Habitats
Remote Sensing in Ecology and Conservation, EarlyView.We compared traditional bird counts (PC) with passive acoustic monitoring (PAM) in a heterogeneous Alpine landscape. PAM recorded twice as many species, with a strong correlation between species richness and the bird counts (rs = 0.71); however, there were significant differences depending on habitat type.
