It was discovered in 1952 that 3–amino–1,2,4–triazole (amitrole) possesses defoliating and regrowth inhibiting properties in cotton. Subsequent study has shown that its most dramatic effect is in the inhibition of chlorophyll formation. Since it is readily absorbed by roots, is translocated throughout the plant, is a general growth inhibitor, and is effective in low concentrations, it is a potentially valuable systemic herbicide. It has been used successfully in the control of quackgrass, nutsedge, Canada thistle, and such woody plants as poison ivy.
