Application Tips for Clipper Herbicide

Clipper is a contact herbicide that quickly breaks down in water. Good coverage and contact time is key to getting satisfying control results. Make applications of Clipper Herbicide with sufficient volume of water according to the label. When making applications to floating or emergent weeds, apply at 6 to 12 oz per acre and mix with an adjuvant approved for aquatic sites. For subsurface applications apply Clipper at 200 to 400 ppb in the water column. Please see label for information on the effects of high pH on plant response and efficacy.


Precautions and Restrictions To Keep In Mind When Using Clipper Herbicide

* No restrictions for swimming, drinking, or fishing.

* DO NOT apply to intertidal or estuarine areas.

* In areas with dense weed vegetation only treat 1/2 the water body at one time and wait 10-14 days before treating the remaining area. DO NOT re-treat the same section of water within 28 days of application.

* Treated water may not be used for irrigation purposes on food crops until at least five days after application.

* Treated water may be used for irrigation purposes on turf and landscape ornamentals as outlined in the Irrigation Restrictions Following Application table below.

* DO NOT use in water utilized for crawfish farming.

* DO NOT re-treat the same section of water with Clipper more than 6 times per year.

* DO NOT exceed 400 ppb of Clipper during any one application.

Then after add 1 tablespoon of this product (Clipper Herbicide) to the jar. Then you will add 4 tablespoons of your chosen additive (for exact instructions depending on the type of additive added and ratios check the label). Place the cap on the jar and invert the jar 10 times and wait 15 minutes. The final mix should be uniformly distributed and should have no floating particles if the mix has layers of oils, fine particles suspended in the mixture, or there is a coagulated texture you should question the adjuvant you have chosen.


To use this product as a surface application to treat floating and emerged weeds, apply at a rate of 6 to 12 ounces of product per acre.

Application in the early morning hours may enhance weed control, as pH level then to rise in the afternoon hours as product breaks down and loses herbicidal effectiveness in high pH water levels (greater than 8.5)


Rapid decomposition of vegetation resulting from the effect of this product may result in loss of oxygen in the water. A sudden decrease in oxygen in water can result in fish suffocation. To avoid this, if aquatic vegetation is dense, treat surface weeds in sections to avoid oxygen decrease. Treat half of the water body and wait 10 to 14 days before finishing the other half. Do not-retreat the same section within 28 days after initial application.


To control submersed and floating weeds using subsurface application, apply at a rate of 100 to 400 ppb (part per billion of active ingredient flumioxazin) in the water column. Apply in a sufficient volume of water per acre to ensure adequate contact with targeted weeds. A subsurface Application Rate table can be found on the label, use it to determine of product needed to achieve the desired concentration at different water depths.


Do not exceed 400 ppb of the active ingredient during any one application.


When making applications to water bodies with a depth greater than 7 feet deep, do not exceed 14.8 pounds of product per surface acre. 


To ensure adequate coverage apply this product with weighted trailing hoses in order to place the product under the surface and throughout the biomass of aquatic vegetation. Keep swath width to a minimum in order to maximize contact with submersed aquatic vegetation.
