Rapid evolution of invasive traits facilitates the invasion of common ragweed, Ambrosia artemisiifolia

Journal of Ecology, 2019
Invasive alien plants, together with organisms introduced for biological control, are ideal study systems with which to address questions of whether, and how fast, organisms adapt to changing environments.

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control

Pest Management Science, EarlyView.
This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

A parlagfű (Ambrosia artemisiifolia) integrált gyomszabályozása, különös tekintettel a kórokozó gombákkal megvalósítható biológiai védekezésre = Integrated control of common ragweed (Ambrosia artemisiifolia) including a biocontrol strategy using plant pathogenic fungi [PDF]

, 2008
A projekt fő célkitűzései között szerepelt a parlagfű ökológiájának és változékonyságának vizsgálata, hazai és észak-amerikai természetes ellenségeinek azonosítása és biológiájuk tanulmányozása, elsősorban a parlagfű elleni biológiai védekezésben történő

Development and Preliminary Evaluation of a Machine Vision‐Guided Smart Sprayer Prototype Toward Precision Vegetable Weeding

Journal of Field Robotics, EarlyView.
ABSTRACT Sustainable weed management necessitates herbicide‐reduced, precision weed control. Recent advancements in machine vision and artificial intelligence (AI) for weed recognition and localization have created new opportunities for high‐precision weeding. Although blanket spraying systems are widely used for weed removal, machine vision‐guided, AI‐

Development of a Remote Sensing-Based Method to Map Likelihood of Common Ragweed (Ambrosia artemisiifolia) Presence in Urban Areas

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
Common Ragweed (Ambrosia artemisiifolia) is a plant that constitutes an important and growing public health concern worldwide as it is probably expanding with climate change, which brings forward the need for improved mapping tools.

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

Insect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

Why is biocontrol of common ragweed (Ambrosia artemisiifolia), the most allergenic weed in Eastern Europe, still only a hope? [PDF]

, 2007
This chapter presents the story of a long and as yet unsuccessful struggle to find suitable fungal and/or insect biocontrol agents for ragweed, a plant that became a widespread allergenic weed in Eastern Europe.

Seed germination niche for common ragweed (Ambrosia artemisiifolia L.) populations naturalized in Turkey

South African Journal of Botany, 2019
Common ragweed (Ambrosia artemisiifolia L.) is an invasive species, and is currently spread in different habitats over several regions in Turkey. However, no information exists on the seed germination biology of Turkish populations.

Efficacy of House Dust Mite Immunotherapy in Chinese Allergic Rhinitis Patients With Diverse Sensitization Patterns: A Multicenter Study (COVER Study)

Allergy, EarlyView.
This prospective multicenter study corroborates the efficacy of AIT with the native HDM allergen extract in Chinese AR patients with diverse HDM sensitization patterns. HDM sensitization pattern affects the efficacy of AIT, with patients sensitized to both major and minor allergens of HDM showing improved outcomes with HDM SCIT.

Growth analysis of Ambrosia artemisiifolia [PDF]

Revista Ceres
We hypothesized that common ragweed has rapid growth and development in shoots and roots, which explains its high potential for establishment in the areas, as well as the high regrowth capacity after cutting or application of contact herbicides.
