Biological control of weeds by means of plant pathogens: Significance for integrated weed management in modern agro-ecology

Biological control of weeds by using plant pathogens has gainedacceptance as a practical, safe, environmentally beneficial, weedmanagement method applicable to agro-ecosystems. The interest in thisweed control approach from public and private groups, and support forresearch and developmental effort, are on the upswing. This increasinginterest is stimulated largely due to major economic, social, andenvironmental forces that are directing our choices in crop productionpractices. Some of these changes are market-driven while others aresocial and ecological in nature. These changes are in turn influencingthe choices in weed control methods. In this regard, biocontrol withplant pathogens has been proven a feasible, albeit minor, component ofmodern integrated weed-management systems. This environmentallybeneficial method should be promoted and exploited further to meet thecurrent and future challenges in weed management in agro-ecosystems.
