Hi Rajgopal, Greetings from Jaipur. You are very much correct. I have gone through the literature for biological control of weeds and also how to prevent the aquatic weed problem. The first thing is that the source of aquatic weeds be identified and treated. In Chambal Project canals in Rajasthan we have this problem. The Bye passing of old tanks in the canals has been done / being done. The uprooting of weeds from bed of canals is also being done regularly. Weeds develop in clear water. Biological treatment in canals in hundreds of miles may not be very much practicable. It may more suitable in lakes and reservoirs.
