Use and Care Manual

With aerial applications, use a drift control system such as Microfoil or Thru-Valve
booms, or use Nalco-Trol or Arborchem 38-F drift control additive or equivalent.
Keep spray pressures low enough to provide coarse spray droplets. Do not use a
thickening agent with the Microfoil or the Thru-Valve booms, or other systems that
cannot accommodate thick sprays.
Spray Drift Management
Avoiding spray drift at the application site is the responsibility of the applicator and
the grower. The interactions of many equipment and weather related factors deter-
mine the potential for spray drift. The applicator and the grower are responsible for
considering all these factors when making decisions.
2,4-D esters may volatilize during conditions of low humidity and high temperatures.
Do not apply during conditions of low humidity and high temperatures.
Droplet Size
When applying sprays that contain 2,4-D as the sole active ingredient, or when ap-
plying sprays that contain 2,4-D mixed with active ingredients that require a coarse
or coarser spray, apply only as a coarse or coarser spray (ASAE standard 572) or
a volume mean diameter of 385 microns or greater for spinning atomizer nozzles.
When applying sprays that contain 2,4-D mixed with other active ingredients that re-
quire a medium or more ne spray, apply only as a medium or coarser spray (ASAE
standard 572) or a volume mean diameter of 300 microns or greater for spinning
atomizer nozzles.
Wind Speed
Do not apply at wind speeds greater than 10 mph. Only apply this product if the wind
direction favors on-target deposition and there are not sensitive areas (including, but
not limited to, residential areas, bodies of water, known habitat for nontarget species,
nontarget crops) within 250 feet downwind. If applying a medium spray, leave one
swatch unsprayed at the downwind edge of the treated eld.
