Thanks, Shan, your advice is extremely helpful. I recognize you are operating out of Georgia and I am in northern Pa., but I'm hoping things basically work the same on the subject matter under discussion.
I do want to confirm that I did carefully research my weed types and I definately have the species mentioned. Second, I did mark my pond off with little pieces of florescent orange flagging tape along the shore at 100 foot intervals when I did a thorough measurement and calculation of my pond's size. I can now see how I can put those markings to good use in applying herbicides. Basically, from what you described, it sounds like when you get your area for treatment measured off, such as a shoreline, you just keep re-spraying that area with your herbicide (such as Reward) until you use up your recommended quantity of material for that space.
So, for example, 1/4 acre is equal to 10,890 sq. ft.. If I do a shoreline 40' out from shore and 270 ft. long, that comes out to 10,800 sq. ft. and I should apply a total quantity of 1-2 quarts of Reward plus clean water over that space with my trusty pump sprayer. Just keep going over that area evenly until the recommended quantity of herbicideis sprayed out. Sounds good to me.
One other question if you have time. Do the plants have to have their tops at the water's surface to be in contact with the Reward for it to work? I'd hate for them to get that mature and large before spraying, but if that is a requirement, I will wait until they reach that stage. I realize Reward is a contact herbicide, but I thought it could travel threough the water column to get to the leafs of the plants and do its destructive thing. Maybe that's where I'm also making a mistake.
Thank you again. I truly do appreciate all of the PondBoss members who have been so helpful to me thus far. I'm hoping by this time next year, I will be more independent with my pond management. (plus I am adding Grass Carp to my pond to cut down on this herbicide thing. I just put 10 in last Monday)
