Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

open access: yesPest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Cytoskeleton in the Parasitic Plant Cuscuta During Germination and Prehaustorium Formation

open access: yesFrontiers in Plant Science, 2018
Although cytoskeleton is a driving force for cell division and growth in higher plants, there is little evidence about its components in parasitic angiosperms.

Parasitic fungi on selected invasive weeds [PDF]

open access: yes, 2010
Parasitic fungi on selected invasive weeds Zuzana Forejtová Abstract This thesis deals with the invasive plant species problems and their pathogens in the Czech Republic. Special attention is given to weed species colonizing the agroecosystems. The modes

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

open access: yesPest 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

Identification of Structural Features of Hydrocinnamic Acid Related to Its Allelopathic Activity against the Parasitic Weed Cuscuta campestris

open access: yesPlants, 2022
Cuscuta campestris is a parasitic weed species that inflicts worldwide noxious effects in many broadleaf crops due to its capacity to withdraw nutrients and water directly from the crop vascular system using haustorial connections.

Weeds, worms and geostatistics

open access: yes, 2010
Weeds and plant-parasitic nematodes occur in patches in agricultural fields. Farmers can control them with chemicals. They can do so precisely and prevent competition (from weeds) and predation (by nematodes) provided they know where the pests are early ...

Soil‐dependent variation in strigolactone signaling distance revealed by a parasitic seed germination bioassay

open access: yesPest Management Science, EarlyView.
A parasitic seed germination bioassay reveals strong soil‐dependent variation in strigolactone signaling distance, controlled by physical and biological soil properties, which shapes signaling range and parasitic weed infection risk. Abstract BACKGROUND Strigolactones are root‐exuded plant metabolites acting as germination stimulants for several ...

The failing firm defence: merger policy and entry

open access: yes, 2003
This paper considers the 'failing firm defence', the principle found in most antitrust jurisdictions that a merger which would otherwise be blocked due to its adverse effect on competition might be permitted when the firm to be acquired is a failing firm

A preliminary approach for modelling the effects of cropping systems on the dynamics of broomrape (Phelipanche ramosa) in interaction with the non-parasitic weed flora

open access: yesOléagineux, Corps gras, Lipides, 2011
The current decrease in herbicide use may increase and diversify weed flora in crops as well as companion bioagressors spreading via weeds. Among these bioagressors is Phelipanche ramosa (L.) Pomel, a parastic plant which is very harmful on oilseed rape.

Endophytic fungi from two isolated Bethencourtia palmensis populations: metabolomic and bioactivity fingerprinting

open access: yesPest Management Science, EarlyView.
We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.
