Indaziflam (Alion)
WSSA Group 29: inhibits cellulose biosynthesis

Alion is labeled for the pre-emergence control of many annual grasses and broadleaf weeds. Controls perennial weeds from seed, only. The spectrum of weeds controlled will be affected by rate and the timing of activation.
Alion is most effective when applied in the fall or early spring to dry soil surface that does not have crack or depressions. Apply as a uniform broadcast or banded application. Alion applications should be followed by 48 hours without irrigation or rain; activating moisture (0.25 to 0.5 inches) must be received within 21 days or before weed seeds germinate. Do not use on sand or soils containing >20% gravel. Alion should not be applied to frozen or snow covered soils, or saturated soils. Use only on vines established at least three years that are exhibiting normal growth and good vigor. Ensure that there is 6 inches of soil between the soil surface and the major portion of the root. Do not apply more than 5 fluid ounces of formulated product (0.065 lbs of active ingredient) per acre per year; coarse soils with less than 1% organic matter require a lower use rate per application. If making more than one treatment per year, allow for 90 days between applications. Do not apply within 14 days of harvest. Clean spray tank thoroughly after use. Surface and groundwater advisories are included on the label because of potential to harm nontarget aquatic organisms, and potential for runoff and percolation to ground water.
