Biology and Management of Hairy Bittercress (Cardamine hirsuta) in Ornamental Crop Production

EDIS, 2015
Bittercress commonly grows in the potting media of container-grown ornamentals and often through drainage holes in nursery containers. It also can be a problem in propagation houses, greenhouses, and in the field. This 6-page fact sheet provides species

Effect of Pre and Post Moisture Level on Preemergence Control of Hairy Bittercress (Cardamine hirsuta L.) with Flumioxazin [PDF]

Journal of Environmental Horticulture, 2013
Moisture is an important component to activate preemergence herbicides; however, this aspect had not been investigated in soilless substrate. The objective of this study was to evaluate the influence of pre-application moisture levels and post-application irrigation levels in the preemergence control of hairy bittercress with flumioxazin in a pine bark

Can Predation Pressure Help Explain the Curious Evolution of Ballistic Seed Dispersal? [PDF]

Ecol Evol
ABSTRACT Ballistic seed dispersal (ballochory) involves the autonomous explosive release of seeds from adult plants. The unconventional mechanics of this strategy have understandably drawn considerable scientific attention. The explosive release of seeds is achieved by a variety of physical mechanisms but broadly involves the rapid coiling or ...

Phylogenomic Barcoding of Soil Seed Bank-Persistent and Wind-Dispersed Non-Native Plant Species in South Georgia. [PDF]

Mol Ecol Resour
ABSTRACT Climate change and invasive species are leading drivers of biodiversity loss, with island ecosystems being especially vulnerable. South Georgia, a remote sub‐Antarctic island, is 170 km long with approximately 30,000 ha of vegetated coastal areas, as snow and ice dominate the inland regions.
