Johnsongrass is a perennial weed that is capable of reproducing by means of seed and rhizomes. Polymerase chain reaction-random amplified polymorphic DNA (PCR-RAPD) technique was used to examine the reproduction and genetic variation within 10 Johnsongrass populations in Kansas. Two twenty-base...

The trumpet tree (Cecropia peltata) is a small weedy tree from humid tropical America, which was introduced to Africa around 1910. For half a century after introduction, the trumpet tree remained a welcome guest in West and Central Africa, spreading only very slowly, before it began to invade...

Chromolaena odorata is a perennial weed which invades forest areas cleared for developing plantations, nurseries, young plantations, and wastelands, but is conspicuously absent in the interior of dense forests or established plantations with closed canopy. The fresh seeds of C. odorata were found...

The pathogenicity and reproductive potential of Meloidogyne mayaguensis and M. floridensis, two new species recently reported in Florida agriculture, were compared to those of M. arenaria race 1, M. incognita race 4, and M. javanica race 1 on tomato (Lycopersicon esculentum) in field microplots....

Water hyacinth (Eichhornia crassipes Solms) is one of the most well-known invasive aquatic plants in the world In Thailand, apart from this species, there are plants species, which are gradually and steadily increasing their area of invasion, such as narrowleaf cattail (Typha angustifolia), Florida ...

Using published matrix population models for 21 invasive plant species with different life histories, we examined responsiveness to survival, growth and fecundity perturbations, and determined which life stages and demographic processes to target for the greatest reductions in population growth...

Koster's Curse (Clidemia hirta (L.) D. Don) is a highly invasive shrub which has the potential to become a major weed in many parts of Queensland and elsewhere in Australia. C. hirta is perennial, can grow to 5 m in height and mature plants are capable of producing in excess of 500 berries annually ...
