Hydrothol Granular with alkylamine endothall is a selective, rapid-acting, contact herbicide and algaecide. Controls submersed weeds and algae in lakes, ponds, irrigation canals, and drainage ditches. Works rapidly enough to be effective in both still and slow-moving water. May be harmful to fish at recommended application rates.

Aquathol with a boost!

The physical form, mode of action, and general usage of Hydrothol Granular are similar to Aquathol Super K Granular. Where fish are present, application of Hydrothol Granular at rates over 0.3 ppm should be used only for spot treatments, narrow margins, or where some fish kill is acceptable. Do not treat more than 10% of a lake or pond at one time at application rates above 1.0 ppm.

When treating lakes or ponds with Hydrothol Granular, begin at shoreline and work toward center. Apply parallel to the shoreline. This will herd fish away from the treated area into deeper, untreated portions of the lake or pond.

Treat your entire pond for algae.

Lakes and Ponds:

Algae can be controlled with as little as 0.2 ppm of Hydrothol Granular when the entire pond is treated. For longer term control or spot treatments, use 0.5 to 1.5 ppm. Repeat treatment when growth reappears. For floating mats, scatter uniformly over the surface of the mat.

Weeds can be controlled with 0.5 to 3.0 ppm of Hydrothol Granular.  For most Pondweeds, 1.0 to 2.0 ppm will give excellent control.  When treating an entire pond you can use 25% to 50% less material.  

To determine pounds of Hydrothol Granular to use per 1,000 sq. ft.:

(application rate in ppm) x (average depth in feet) x (1.25) 

To use 1.5 ppm at an average depth of 4.0 feet:

1.5 x 4.0 x 1.25 = 7.5 pounds per 1000 sq. ft.

Canals and Ditches:
Irrigation canals or drainage ditches will require 3.0 to 5.0 ppm of Hydrothol Granular.

To determine pounds of Hydrothol Granular in canals and ditches:

(application rate in ppm) x (1000's of linear ft.) x (cross section in sq. ft.) x (1.25) 

To use 3.0 ppm over 2,000 feet with a cross section of 15 sq. ft.:

3.0 x 2.0 x 15 x 1.25 = 112.5 lbs.

Treat heavy infestations in sections of 1/3 to 1/2 of the total weed volume to avoid oxygen depletion.  Allow 5 to 7 days before continuing to untreated sections.

See Water Use Restrictions (Days).

Great Bag
Color: Brown
Okay I was hesitant on buying this bag. Finally did it. I can say OMG this bag is everything. I have recently started to love carrying the backpack bags as everyday bags. The one I have is a little big so looking for a smaller one. This one is more medium size with plenty of pockets. The color was beautiful. It seems it will hold up for a while.

Perfection, Or Close to It
Color: Black
I absolutely love this bag! Now that my child is a toddler, I’ve found it easiest to combine my purse and diaper bag into one bag. I no longer need to lug around a huge diaper bag full of bottles, blankets, etc., but I did need enough room to store toddler essentials (a few diapers, a changing pad, wipes, diaper cream, snacks, snack, and more snacks, medicine, a couple of wash cloths, and a toy) plus my essentials (wallet, keys, lotion, lip balm, eye drops, kindle). This has room enough for all of those things without it being an oversized purse or a full sized backpack. A lot of purses will state that they have a lot of different compartments, but the compartments won’t be a size that makes it actually useful, but this purse is different. Each compartment is spacious. Plus, the compartment on the back that’s a secure place for your phone or wallet is actually big enough to store things without having to squeeze it in! If I could give this purse 6 stars, I would. My only qualm is wishing the straps were a different material so that they wouldn’t readjust the size so easily. But if you slide the metal part up toward the decorative leather part of the strap, the leather adds friction and stops it from sliding down.

Beautiful Color
Color: Green
This was a very nice purse. It seemed to be of good quality and I loved the color. I did return it because it was just too big for my tastes and needs. I loved the functionality of it with all the pockets, but didn't want to carry around a backpack sized purse. I would recommend it for anyone who likes large purses. Seller was wonderful to work with.
