Drift Buffer Demo (47.48 ac)

For aerial applications using medium to coarse droplet sizes, a 75 foot in-field, wind-directional buffer for windspeeds =<10 mph or a 100 foot in-field, wind-directional buffer for windspeeds 11-15 mph are required. For aerial applications using coarse to very coarse droplet sizes, a 40 foot in-field, wind-directional buffer for windspeeds =<10 mph or a 50 foot in-field, wind-directional buffer for windspeeds 11-15 mph are required. The applicator must maintain the appropriate in-field, wind-directional buffer as described above from treatment sites to any area except the following: 1) Roads, paved or gravel surfaces, 2) planted agricultural fields, 3) agricultural fields that that have been prepared for planting, or 4) areas covered by the footprint of a building, shade house, silo, feed crib, or other man-made structure with walls and/or a roof. In-field, wind directional buffers can be maintained at half the distance required above when windbreaks (e.g., trees or riparian hedgerows) between the application site and all areas except those listed above are present. The windbreak would need to have a row of broad-leaved trees the full length of the treated crop with leaves visible over the entire length, with no significant gaps. The height of the trees or windbreak would need to be at a height greater than the crop to be sprayed.
