Pest categorisation of Diplodia bulgarica. [PDF]

EFSA J, 2023
Abstract The EFSA Plant Health Panel performed a pest categorisation of Diplodia bulgarica, a clearly defined plant pathogenic fungus of the family Botryosphaeriaceae. The pathogen affects Malus domestica, M. sylvestris and Pyrus communis causing various symptoms such as canker, twig blight, gummosis, pre‐ and post‐harvest fruit rot, dieback and tree ...

Identification of Tomato Disease Types and Detection of Infected Areas Based on Deep Convolutional Neural Networks and Object Detection Techniques. [PDF]

Comput Intell Neurosci, 2019
This study develops tomato disease detection methods based on deep convolutional neural networks and object detection models. Two different models, Faster R‐CNN and Mask R‐CNN, are used in these methods, where Faster R‐CNN is used to identify the types of tomato diseases and Mask R‐CNN is used to detect and segment the locations and shapes of the ...

A Novel Vision Sensing System for Tomato Quality Detection. [PDF]

Int J Food Sci, 2014
Producing tomato is a daunting task as the crop of tomato is exposed to attacks from various microorganisms. The symptoms of the attacks are usually changed in color, bacterial spots, special kind of specks, and sunken areas with concentric rings having different colors on the tomato outer surface. This paper addresses a vision sensing based system for

Rye–vetch residue quality and plastic mulch affect soil nitrogen dynamics in vegetable production systems

Agronomy Journal, Volume 115, Issue 3, Page 1463-1477, May/June 2023., 2023
Abstract Cover crops can be an important source of nitrogen (N) for organic vegetable production, but N availability depends on the characteristics of the cover crop residues and crop management practices following termination. A 2‐year field experiment in Michigan investigated (1) how the proportion of cereal rye (Secale cereale L.) and hairy vetch ...
