Patternator Results - 2012

Total Spray Recovery

The mean of the total amount of spray captured by the SARE and modified Cornell patternator was calculated. The mean of the four replicates for each patternator was compared to the mean of the replicates for the total output of the sprayer to give the percentage recovery.

Table 9. Total spray recovery

total output: 1969 ml
Treatment Mean recovery
Cornell 471.5 ml 24.0%
SARE 1046.25 53.1%

The percentage of the total spray captured by the two patternators reiterates the statistical significance found when comparing the individual panels. The SARE patternator captured more than twice as much total spray as compared to the modified Cornell patternator. Similar results were obtained in 2010.
