Fully Convolutional Networks with Sequential Information for Robust Crop and Weed Detection in Precision Farming [PDF]

open access: yes, 2018
Reducing the use of agrochemicals is an important component towards sustainable agriculture. Robots that can perform targeted weed control offer the potential to contribute to this goal, for example, through specialized weeding actions such as selective spraying or mechanical weed removal.

A Survey of Deep Learning Techniques for Weed Detection from Images [PDF]

open access: yesarXiv, 2021
The rapid advances in Deep Learning (DL) techniques have enabled rapid detection, localisation, and recognition of objects from images or videos. DL techniques are now being used in many applications related to agriculture and farming. Automatic detection and classification of weeds can play an important role in weed management and so contribute to ...

Surface Engineering‐Induced d‐Band Center Down‐Regulation in High‐Entropy Alloy Nanowires for Enhanced Nanozyme Catalysis

open access: yesAdvanced Science, EarlyView.
PtRuFeCoNi HEA NWs are synthesized by adjusting the metal composition and surface‐engineered with PDA to create HEA NWs@PDA nanozymes with superior catalytic activities and photothermal properties. DFT calculations confirm that self‐polymerized PDA surface engineering moderately lowers the d‐band center of the HEAs, optimizes the surface charge ...

Synthesis and biological profile of 2,3-dihydro[1,3]thiazolo[4,5-b]pyridines, a novel class of acyl-ACP thioesterase inhibitors

open access: yesBeilstein Journal of Organic Chemistry
The present work covers novel herbicidal lead structures that contain a 2,3-dihydro[1,3]thiazolo[4,5-b]pyridine scaffold as structural key feature carrying a substituted phenyl side chain. These new compounds show good acyl-ACP thioesterase inhibition in

A Low-cost Robot with Autonomous Recharge and Navigation for Weed Control in Fields with Narrow Row Spacing [PDF]

open access: yesarXiv, 2021
Modern herbicide application in agricultural settings typically relies on either large scale sprayers that dispense herbicide over crops and weeds alike or portable sprayers that require labor intensive manual operation. The former method results in overuse of herbicide and reduction in crop yield while the latter is often untenable in large scale ...

Effects of organic and chemical nitrogen fertilization and postharvest treatments on the visual and nutritional quality of fresh‐cut celery (Apium graveolens L.) during storage

open access: yesFood Science &Nutrition, Volume 11, Issue 1, Page 320-333, January 2023., 2023
Nowadays, consumers have an increasing preference for vegetables produced using healthier and environmentally friendly techniques. The postharvest quality of fresh‐cut celery is affected by nitrogen (N) fertilizer rate and type (organic and chemical) as well as postharvest treatments.

DeepWeeds: A Multiclass Weed Species Image Dataset for Deep Learning [PDF]

open access: yesSci.Rep. 9, 2058 (2019), 2018
Robotic weed control has seen increased research of late with its potential for boosting productivity in agriculture. Majority of works focus on developing robotics for croplands, ignoring the weed management problems facing rangeland stock farmers. Perhaps the greatest obstacle to widespread uptake of robotic weed control is the robust classification ...

A Concept of a Compact and Inexpensive Device for Controlling Weeds with Laser Beams

open access: yesAgronomy, 2020
A prototype of a relatively cheap laser-based weeding device was developed and tested on couch grass (Elytrigia repens (L.) Desv. ex Nevski) mixed with tomatoes. Three types of laser were used (0.3 W, 1 W, and 5 W).
