Eragrostis plana Nees is a weed of high aggressiveness and great capacity of invasion, capable of displacing productive species of natural grassland up to their complete substitution. Recently, its presence in Uruguay has increased significantly, fundamentally, in bordering areas with Brazil,...

Hakea salicifolia and Hakea sericea are seriously invasive species in the Portuguese mainland. In this work seed germination and viability was evaluated for different pre-treatments and germination temperatures. Recently harvested fruits and seeds were submitted to heating and seed survival was...

Four years of experience in controlling Sicyos angulatus, indicate that the attempt to control and eradicate an invasive plant is expensive and not immediate. The keys to success in controlling an invasive plant are: having a network of field technicians enabling rapid problem detection and rapid...

Hakea salicifolia and H. sericea are seriously invasive species in the Portuguese mainland. In this work leaf morphoanatomy implications on glyphosate efficacy were studied. In order to explore means of chemical control, young plants of both species were sprayed with glyphosate and adjuvants. 100% ...

Manual and mechanical removal, and herbicides are the major weed management practices currently used in the agricultural systems in Latin-America. Biological control of invasive plants, using mainly host-specific insects and in a lesser extent plant pathogens, has been traditionally practiced in...

Despite of the usually weed management; the urban locals have a bigger biodiversity than we may think. These tasks related to weed control, also must be extremely safe. This work involved three different aspects: (1) weed surveys on streets and tree/flower-beds; (2) weed control methods usually...

In Mexico about 25% of the budget for conservation of the Irrigation Districts is intended to weed control of canals, drains and roads. The main control method is the mecanichal, requires machinery that does not damages the section and allowing the development of a vegetation which root system...

Starting from the agronomic practices that have always been forever the basis for weed control, and taking into consideration the legal, economic and environmental factors that define the current pest management scenary, I review three key aspects: weed sampling, decision making and control...

An unresolved, long-standing debate of fundamental importance to the success and efficiency of weed biological control is whether a single "most effective" type of herbivore insect or a set of insects in "complementary" feeding guilds is more likely to limit invasive plant density. These two...

According to Official Mexican Standard 043-FITO-1999 "Specifications on preventing introduction of quarantined weeds in Mexico" a quarantined weed is defined as that which is not present in Mexico or if so, it is found in a definite area and is officially controlled. This Standard includes a list...
