| Abstract/Contents: | "Field tests showed that the lawn spray-gun with a 4 gpm lawn tip reduced the percentage of application volume deposited 90 cm to 210 cm downwind from the spray swath edge when compared with XR8004 flat-fan or RA-6 wide angle hollow cone applications at wind speeds between 4.7 and 14.4 km/h. The percentage of applied volume collected at 210 cm downwind from the XR8004 flat-fan applications was 5 and 16 times greater than the percentage from the RA-6 raindrop nozzle and lawn spray-gun applications, respectively. Visible injury along with height increases and fresh weights from tomato plants located downwind from the applications concur with spray-drift data for all nozzle types. Triclopyr injury decreased as the distance from the swath edge increased. All tomato plants located downwind up to 210 cm from the XR8004 flat-fan applications were visibly injured (15-40%); whereas, only plants less than 150 cm dowmwind from the RA-6 raindrop applications and less than 90 cm downwind from the lawn spray-gun applications were injured (2 to 8%)." |
