I'm wanting to use a 2,4-D Amine formulation to treat American Lotus in a 3 acre pond. Only the back shallow areas (about 1 acre) are infested with the weed, and I was hoping that I could treat only that area next spring. It's my understanding that the 2,4-D pellet version can be used to spot treat certain pond areas since they are effective at attacking the root system in a more systematic absorption way rather than by contact. However, I'm not sure about the liquid 2,4-D version. Can I treat only the affected area with the liquid or will wave motion dilute it too much to be effective ? The product label for the liquid is not definitive for piecemeal applications, but only about product amounts per acre feet. Has anyone had any experience using either of the liquid or pellet versions ? The pellets are considerably more expensive so I'm hoping to use the liquid.
