The timing of the Thinrite (endothall)
applications were made at 80% full bloom of
the latest blooming cultivar on 6 May.
Endothall was applied at 3x concentrate (85
gpa). Treatments were applied at a speed of
2.8 MPH at 250 PSI as calibrated. The
timing of the Amid Thin (NAD) treatment
was left to the discretion of the grower based
on weather conditions and his past experience
with NAD performance. The Amid Thin
treatments were applied dilute (250 gpa) on
15 May. This treatment date occurred in the
middle of a four-day period of full sun with
daytime maximum temperatures averaging

Table 3: Cultivars and treatments, Experiment 2.
Note: Not all varieties received all three treatments. The determination of cultivar treatments was again
left up to the grower's discretion in order to accommodate his management practices.
