Potential wheat yield loss due to weeds in the United States and Canada

open access: yesWeed technology, 2021
Yield losses due to weeds are a major threat to wheat production and economic well-being of farmers in the United States and Canada. The objective of this Weed Science Society of America (WSSA) Weed Loss Committee report is to provide estimates of wheat ...

Recent Weed Control, Weed Management, and Integrated Weed Management [PDF]

open access: yesWeed Technology, 2013
Integrated weed management (IWM) can be defined as a holistic approach to weed management that integrates different methods of weed control to provide the crop with an advantage over weeds. It is practiced globally at varying levels of adoption from farm to farm.

Distributional composition using higher-order dependency vectors [PDF]

open access: yes, 2014
This paper concerns how to apply compositional methods to vectors based on grammatical dependency relation vectors. We demonstrate the potential of a novel approach which uses higher-order grammatical dependency relations as features.

Species composition of semi‐natural mesic grasslands as a factor influencing the methane yield of plant biomass (Central Europe)

open access: yesGCB Bioenergy, 2022
Semi‐natural lowland and mountain mesic meadows are grasslands rich in species, and their conservation status depends on treatments such as mowing or grazing livestock.

Agricultural intensification and climate change have increased the threat from weeds

open access: yesGlobal Change Biology, 2021
Weeds represent a significant threat to crop yields and global food security. We analysed data on weed competition from the world's longest running agricultural experiment to ask whether potential yield losses from weeds have increased in response to ...

Pretilachlor Releasable Polyurea Microcapsules Suspension Optimization and Its Paddy Field Weeding Investigation

open access: yesFrontiers in Chemistry, 2020
In this study, pretilachlor was encapsulated into polyurea microcapsules prepared by water-initiated polymerization of polyaryl polymethylene isocyanate and eventually made into pretilachlor microcapsules suspension (PMS).

Autumn mowing and pelargonic acid can suppress Elymus repens abundance especially when combined with increased crop competition

open access: yesJulius-Kühn-Archiv, 2022
Couch grass (Elymus repens) is a creeping perennial weed that can cause great yield losses in a wide range of crops. Established stands are usually controlled by glyphosate, selective herbicides, or intensive tillage.

Understanding the combined impacts of weeds and climate change on crops

open access: yesEnvironmental Research Letters, 2021
Crops worldwide are simultaneously affected by weeds, which reduce yield, and by climate change, which can negatively or positively affect both crop and weed species.
