Application

Hand-Held Sprayers: Hand-held or backpack sprayers may be used for spot applications of Alligare Picloram 22K if care is taken to apply the spray uniformly and at a rate equivalent to a broadcast application. Application rates in the table are based on an area of 1,000 sq. ft.

Mix the amount of Alligare Picloram 22K (fl. oz. or ml) corresponding to the desired broadcast rate in 0.5 to 2.5 gallons of water, depending on the spray volume required to treat 1,000 sq. ft.

To calculate the amount of Alligare Picloram 22K required for larger areas, multiply the table value (fl. oz. or ml) by the area to be treated in “thousands” of square feet, e.g., if the area to be treated is 3,500 sq. ft., multiply the table value of 3.5 (calc. 3,500/1,000 = 3.5). An area of 1,000 sq. ft. is approximately 10.5 x 10.5 yards (strides) in size.

Coverage Area

Each Gallon of picloram will treat up to 4 acres of land.

Time to Kill

Picloram 22K Herbicide begins to kill target weeds 2 weeks after contact but can take up to several weeks for complete control all depending on treatment area and application.

Will this kill Buckhorn Plantain?
Ray H on Aug 24, 2017
BEST ANSWER: It is not listed specifically on the label, but will kill most everything. For control of other broadleaf weeds and woody plants, picloram may be applied broadcast
at up to 0.5 lb ae per acre (1 quart Alligare Picloram 22K per acre) per annual growing season.
Apply spot treatments at an equivalent broadcast rate of up to 1 lb ae per acre (2 quarts
Alligare Picloram 22K per acre) per annual growing season, but not more than 50% of an
acre may be treated. Repeat treatments may be applied as necessary, but total use must
not exceed the maximum amount specified.

Tyler on Jul 19, 2017
BEST ANSWER: Picloram 22K does not breakdown very quickly as other herbicides and is considered to half a half life of 1 to 2 years. Should not consider planting in areas that are treated with Picloram for at least 1 year.
Will Picloram kill Russian or Spotted Knapweed?
Thank you
Basco on Jul 5, 2017
BEST ANSWER: Yes, Picloram is labeled to kill Russian or Spotted Knapweed. This is a Restricted use product and would require a license,
What do you have that is non-restricted use to kill cacti. I have a lot of cactus around my ranch.
Matt on Mar 16, 2017
BEST ANSWER: If you are looking for something non-restricted to kill cacti we have many people who get good results with Triclopyr mixed with Diesel Fuel. Mix 3oz per gallon of fuel and right before spraying see if you can somehow damage the plant either by hitting it with a machete or running it over with a tractor. That will speed up the uptake of the herbicide to ensure root kill. Hope this helps. If you have any questions let me know.
