In water, weed control is hard: opposition of herbicide in water, hard to maintain concentration of moving h20. The most successful is flea beetle: this weed goes on surface of the water. Present vs. future: persistence strategy-we want to hit certain targets. Annual/biennale-introduce insect: perennial- something that eats the seeds, insect control by chemicals.

Most of the time is fungal disease- mycoherbicide. Good candidate for mycoherbicide: virulent, host-specific, generally stable, naturally constrained, able to grow well in culture. How do mycoherbicides work: high doses of fungal propagyles applied to entire host weed population. Improved application technology: factors affecting efficacy of mycoherbicides, compatibility with other mating herbicides.
