Effects of bean seed treatment by the entomopathogenic fungi Metarhizium robertsii and Beauveria bassiana on plant growth, spider mite populations and behavior of predatory mites
(Journal article; Peer reviewed, 2019-02-06)The fungal genera Metarhizium and Beauveria are considered as both entomopathogens and endophytes; they are able to colonize a wide variety of plants and can cause increased plant growth and protect plants against pests. ... -
Effects of integrated grassland renewal strategies on annual and perennial weeds in the sowing year and subsequent production years
(Peer reviewed; Journal article, 2023-03-14)Appropriate weed control measures during the renewal phase of temporary grasslands are critical to ensure high yields during the whole grassland lifecycle. The aim of this study was to determine which integrated grassland ... -
Effects of limited volatiles release by plants in tritrophic interactions
(Journal article; Peer reviewed, 2019-04-17)We introduce a mathematical model to describe the tritrophic interaction between crop, pest and the pest natural enemy where the release of Volatile Organic Compounds (VOCs) by crop is taken into account. The VOCs may be ... -
Effects of mild drought on the morphology of sun and shade needles in 20-year-old Norway spruce trees
(Journal article; Peer reviewed, 2019-02-28)Several studies have looked at how individual environmental factors influence needle morphology in conifer trees, but interacting effects between drought and canopy position have received little attention. In this study, ... -
Effects of renewal time, taproot cutting, ploughing practice, false seedbed and companion crop on docks (Rumex spp.) when renewing grassland
(Journal article; Peer reviewed, 2018-12-05)Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) ... -
