Relationship of vegetation indices with herbicide phytotoxicity in winter cereals [PDF]

Advances in Weed Science, 2021
Abstract Background: The evaluation of selective herbicides for weed control in winter cereals is extremely important. Simple methods to evaluate alterations caused by herbicides in the growth and development of winter cereals can be performed with vegetation indices.

Atmospheric Oxidation of a Thiocarbamate Herbicide Used in Winter Cereals [PDF]

Environmental Science & Technology, 2018
The gas-phase atmospheric degradation of prosulfocarb (a widely used thiocarbamate herbicide in winter cereals) at different NOx concentrations was investigated at the large outdoor European PHOtoREactor (EUPHORE) in Valencia, Spain. Photolysis under sunlight conditions and reaction with ozone were shown as unimportant.

Suppressing Alopecurus myosuroides in winter cereals by delayed sowing and pre-emergence herbicides

Plant, Soil and Environment, 2022
Delayed sowing of winter cereals in Western Europe is a preventive method to reduce Alopecurus myosuroides infestations. Two series of on-farm studies including 36 experiments were conducted in South-Western Germany to analyse the combined effects of ...

The Potential of Arable Weeds to Reverse Invertebrate Declines and Associated Ecosystem Services in Cereal Crops [PDF]

, 2020
There is global concern that invertebrate populations are declining rapidly, particularly in agricultural habitats. Declines have been attributed to the intensification of farming systems, with many studies focussing on a lack of semi-natural habitat in ...

Integrated Palmer Amaranth Management in Glufosinate-Resistant Cotton: I. Soil-Inversion, High-Residue Cover Crops and Herbicide Regimes

Agronomy, 2012
A three year field experiment was conducted to evaluate the role of soil-inversion, cover crops and herbicide regimes for Palmer amaranth between-row (BR) and within-row (WR) management in glufosinate-resistant cotton.

Abundance of Cereal Aphids (Homoptera: Aphididae) and Their Predators in Spring Wheat-Alfalfa Intercrops Under Different Crop Management Intensities [PDF]

, 2018
Natural infestations of cereal aphids and abundance of their predators were compared from 1990 through 1993 among plots of intercropped spring wheat and alfalfa grown under high, intermediate, or low crop management intensity (CMI).

Efficiency, profitability and carbon footprint of different management programs under no-till to control herbicide resistant Papaver rhoeas [PDF]

, 2020
The present work examines the effects of different integrated weed management (IWM) programs on multiple herbicide-resistant Papaver rhoeas populations in terms of effectiveness, profitability and carbon footprint.

Analysis of herbicide residues in cereals, fruits and vegetables

Journal of Chromatography A, 2000
The determination of herbicide residues in cereals, fruits and vegetables by chromatographic methods is reviewed. The principal chemical groups of herbicides, like phenoxyacids, benzonitriles, ureas, triazines, dinitroanilines, chloroacetamides, carbamates, uracils, glyphosate and bipyridylium compounds, are considered.

Grass-weed challenges, herbicide resistance status and weed control practices across crop establishment systems in Ireland’s mild Atlantic climate

Frontiers in Agronomy, 2022
The challenges of grass-weed control in a mild Atlantic climate, added to by the use of non-inversion tillage and limited herbicide options necessitated on-farm knowledge acquisition on grass weeds in Ireland.

Grass weed control and herbicide tolerance in cereals

New Zealand Plant Protection, 2003
Field trials were undertaken over three years to determine herbicide options for grass weed control in cereal crops (wheat and barley) The susceptibility of phalaris perennial ryegrass Italian ryegrass prairie grass and soft brome to a range of herbicides were evaluated at fixed rates and with a logarithmic sprayer Wheat and barley damage and grain ...
