Biological control of weeds.
Classical biological control, i.e. the introduction and release of exotic insects, mites, or pathogens to give permanent control, is the predominant method in weed biocontrol. Inundative releases of predators and integrated pest management are less widely used. The United States, Australia, South Africa, Canada, and New Zealand use biocontrol the most. Weeds in natural ecosystems are increasing...
متن کاملThe Future of Biological Control of Weeds with Insects: No More ‘Paranoia’, No More ‘Honeymoon’
To meet the future challenges facing biological control of weeds, two issues are considered: first the ‘paranoia’ about the threat of biocontrol agents to non-target plant species, and second, the ‘honeymoon’ regarding the lack of accountability for projects that failed to achieve their desired objectives. With a suggested new mindset on these issues, proposals are made to deal with five curren...
متن کاملPlant protease inhibitors in control of phytophagous insects
Plant proteinase inhibitors (PIs) have been well established to play a potent defensive role against predators and pathogens. Although diverse endogenous functions for these proteins has been proposed, ranging from regulators of endogenous proteinases to act as storage proteins, evidence for many of these roles is partial, or confined to isolated examples. On the other hand, many PIs have been ...
متن کاملBiological Control of Weeds Using Plant Pathogens
Changes in program directions at the Saskatoon Research Centre have resulted in the organization of a research team equipped to develop microorganisms for the biological control of important agricultural weeds. This paper presents a brief introduction to the science of inundative biological control and an overview of the research progress made on controlling Canada thistle, wild oats, and green...
متن کاملIsolation and screening of phytotoxin-producing actinomycetes for biological control of Cardaria draba
Cardaria draba is an important, troublesome weed in the sustainable production of wheat. Inthe first step of this study, 100 actinomycete isolates were purified from soil samples collectedfrom the rhizosphere and phyllosphere of plants in different provinces of Iran. All isolates weresubjected to primary screening by assaying the fermentation broth of the sterile surfaces of C.draba leaves. Con...
