Diverse Approaches to Herbicide-Resistant Weed Management [PDF]

Weed Science, 2016
Herbicides have been the principal means of weed control in developed countries for approximately 50 yr because they are the most cost-effective method. Such general use of herbicides has resulted in weed resistance to herbicides, which continues to be a growing problem. Within the past decade, the evolution of resistance to the once-dominant herbicide

Intercropping with legumes can reduce insect pest pressure but does not increase yield in winter oilseed rape (Brassica napus L.)

Pest Management Science, EarlyView.
Intercropping winter oilseed rape with spring faba bean reduced cabbage stem flea beetle and pollen beetle damage but also reduced crop yield. Sowing the intercrop simultaneously with winter oilseed rape was essential to maximize crop protection against cabbage stem flea beetles. Abstract BACKGROUND Winter oilseed rape (WOSR, Brassica napus) is a major

Field performance of MON 94637 and laboratory evidence supporting a Bt pyramiding strategy against key lepidopteran pests in Brazil

Pest Management Science, EarlyView.
A genetically modified soybean expressing multiple Cry proteins protects against key lepidopteran pests, consistently reducing larval damage and offering an effective resistance management option for soybean production in Brazil. Abstract BACKGROUND Pyramided Bt genes in crops have been widely adopted to delay insect resistance evolution worldwide. The

Pro‐197 mutations confer resistance to thiencarbazone but not to foramsulfuron in ALS‐resistant Poa annua populations

Pest Management Science, EarlyView.
Foramsulfuron remains effective on Pro‐197 Poa annua, but co‐formulation with thiencarbazone reduces efficacy due to limited activity and antagonism. Therefore, foramsulfuron + thiencarbazone should be used in fields without ALS‐resistant weeds to ensure effective in‐crop control.

Development of a Geo-Referenced Database for Weed Mapping and Analysis of Agronomic Factors Affecting Herbicide Resistance in Apera spica-venti L. Beauv. (Silky Windgrass)

Agronomy, 2013
In this work, we evaluate the role of agronomic factors in the selection for herbicide resistance in Apera spica-venti L. Beauv. (silky windgrass). During a period of three years, populations were collected in more than 250 conventional fields across ...

Persistence of PPO mutations and dynamics of Amaranthus palmeri resistance to PPO‐inhibitor herbicides in a decade

Pest Management Science, EarlyView.
Over a decade, Arkansas Amaranthus palmeri populations maintained resistance to PPO‐inhibiting herbicides. PPO2 mutations relate to shifts in herbicide resistance patterns over time. Abstract BACKGROUND Amaranthus is a highly troublesome weed genera globally.

No Vegetative and Fecundity Fitness Cost Associated with Acetyl-Coenzyme A Carboxylase Non-target-site Resistance in a Black-Grass (Alopecurus myosuroides Huds) Population

Frontiers in Plant Science, 2017
Attention should be devoted to weeds evolving herbicide resistance with non-target-site resistance (NTSR) mechanism due to their unpredictable resistance patterns.

Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

Pest Management Science, EarlyView.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.

Evaluation of a novel laser‐system operating at 1940 nm for weed control and determining the influence of biological and operational factors

Pest Management Science, EarlyView.
The control efficacy of a novel laser pulse system operating at 1940 nm was tested. The new system allows effective control of young weeds with 1.5 J. Targeting the plant stem is 53‐fold more energy‐efficient than the meristem. Species morphology and beam diameter significantly influence weed control efficacy. Abstract BACKGROUND This study evaluates a
