What is Flumioxazin?
It is a broad spectrum contact herbicide. It works by interfering with the plants production of chlorophyll and is applied in early spring. It is available in granular form (ClipperTM) for control of submerged plants, and can be used as a direct foliar application to control emergent and floating-leaf plants. It also controls some filamentous algae.
What is foliar application?
A foliar application means that you are feeding plants by applying liquid fertilizer directly to the leaves as opposed to in the soil. The absorption takes place through their stomata and their epidermis. Transport is usually faster through the stomata, but total absorption may be as great through the epidermis.Jun 15, 2022
