Fader, 2-4D is a plant growth hormone. Does not work well this time of year. Kills because the plant has uncontrollable growth. The problem is 2-4D only works when a plant is growing so this is not a good time of year to spray. In early spring is best time for 2-4D, an amine salt that is a plant growth hormone.
Whatch a plant sprayed with 2-4D, the plant, the top of the plant curls and grows in all directions, uncontrolled growth like a cancer.
