“…Charudattan & Dinoor [80] also state that, among the limitations of biocontrol of weeds by plant pathogens, the most important are the limited commercial interest in this approach to weed control due to the fact that markets for biocontrol agents are typically small, fragmented, highly specialized, and consequently the financial returns from biocontrol agents are too small to be of interest to big industries; and the complexities in production and assurance of efficacy and shelf-life of inoculum can further stifle bioherbicide development. For instance, the inability to mass-produce inoculum needed for large-scale use is a serious limitation that has led to the abandonment of several promising agents.…”

“…According to Charudattan & Dinoor [80], bioherbicide is defined as a plant pathogen used as a weed-control agent through inundative and repeated applications of its inoculum. In the United States and many other countries, the prescriptive use of plant pathogens as weed control agents is regarded as a "pesticidal use" and therefore these pathogens must be registered or approved as biopesticides by appropriate governmental agencies.…”

“…Solms (Pontederiaceae), continues to pose serious economic, social and environmental problem in India and many other countries in the tropics and subtropics [8]. In recent years, attention has centered on biological control, which could provide a cost-effective environmentally safe, solution to the water hyacinth problem [1,2,4,5,7]. Most emphasis has been given to fungal pathogens as biocontrol agents [11][12][13].…”

Abstract-Water hyacinth [Eichhornia crassipes (Mart.) Solms] is a noxious aquatic weed. In India,it has infested more than 200,000 ha of water surface. During the course of present investigation it was proposed to make an extensive, planned and systematic survey of fungal pathogens that destroy the water hyacinth from the ponds of M.P. The study was undertaken to evaluate the compatibility of two or more fungi for integrated management of water hyacinth. Results clearly indicate that except Alternaria eichhorniae all the pathogens are compatible to each other. In vivo the lesion diameters were greater on water hyacinth leaves when combination of pathogens were used than individual pathogens. The Alternaria alternata, Curvularia lunata and Fusarium pallidoroseum combination resulted in maximum disease development followed by A. alternata with C. lunata, A. alternata with F. pallidoroseum and C. lunata with F. pallidoroseum. Thus, it can be concluded that better management of the weed can be achieved by using combination of pathogens.

“…Different reviews have concluded that the development of herbicide-tolerant crops has revolutionized the crop production in many regions (Beckie et al 2006;Dill et al 2008;Duke and Powles 2009;Green 2012). Although biological weed management is not a panacea under prevailing conditions, it has a great potential (Ash 2010;Charudattan 2001Charudattan , 2005Hallett 2005). Meanwhile, the advancements in technology have created vast opportunities for weed management in the form of thermal techniques, including flaming, solarization, electrocution, and microwave technology (Bond and Grundy 2001;Knežević et al 2011;Rask and Kristofferson 2007).…”

Nonconventional Weed Management Strategies for Modern Agriculture

Weeds are a significant problem in crop production and their management in modern agriculture is crucial to avoid yield losses and ensure food security. Intensive agricultural practices, changing climate, and natural disasters affect weed dynamics and that requires a change in weed management protocols. The existing manual control options are no longer viable because of labor shortages; chemical control options are limited by ecodegradation, health hazards, and development of herbicide resistance in weeds. We are therefore reviewing some potential nonconventional weed management strategies for modern agriculture that are viable, feasible, and efficient. Improvement in tillage regimes has long been identified as an impressive weed-control measure. Harvest weed seed control and seed predation have been shown as potential tools for reducing weed emergence and seed bank reserves. Development in the field of allelopathy for weed management has led to new techniques for weed control. The remarkable role of biotechnological advancements in developing herbicide-resistant crops, bioherbicides, and harnessing the allelopathic potential of crops is also worth mentioning in a modern weed management program. Thermal weed management has also been observed as a useful technique, especially under conservation agriculture systems. Last, precision weed management has been elaborated with sufficient details. The role of remote sensing, modeling, and robotics as an integral part of precision weed management has been highlighted in a realistic manner. All these strategies are viable for today's agriculture; however, site-specific selection and the use of right combinations will be the key to success. No single strategy is perfect, and therefore an integrated approach may provide better results. Future research is needed to explore the potential of these strategies and to optimize them on technological and cultural bases. The adoption of such methods may improve the efficiency of cropping systems under sustainable and conservation practices.
