In, 2017, Weed Wranglers sprayed for common mullein, Canada thistle, bull thistle,
houndstongue, diffuse knapweed, Chinese clematis and Dalmatian toadflax along with other
noxious weeds as detailed on the enclosed Herbicide Application Record. On August 4 a total
of three technicians from Weed Wranglers sprayed with Telar XP at a rate of 1.25 oz per 40
gallons of water (2 oz of herbicide applied), Milestone at a rate of 6 oz per 40 gallons of water
(15.75 oz of herbicide applied), and Escort XP at a rate of 1.25 oz per 40 gallons of water (1.25
oz of herbicide applied) with marking dye added at a rate of 24 oz per 100 gallons of water (25.6
oz applied), and surfactant added at a rate of 32 oz per 100 gallons of water (33.9 oz applied).
On August 8 a total of two technicians from Weed Wranglers sprayed with Telar XP at a rate of
1.25 oz per 40 gallons of water (1.25 oz of herbicide applied), Milestone at a rate of 6 oz per 40
gallons of water (6 oz of herbicide applied) and Vista XRT at a rate of 14 oz per 40 gallons of
water (14 oz of herbicide applied), with marking dye added at a rate of 24 oz per 100 gallons of
water (10 oz applied), and surfactant added at a rate of 32 oz per 100 gallons of water (13 oz
applied). Surfactant was mixed with the herbicide mixture to promote spreading and adhering of
the herbicide mixture to the plant surface. The treated area (approximately 4.5 acres) required
that approximately 140 gallons of combined herbicide mixture be used. The application was
done with telli 1 and 2 hoses and handgun work for spot spraying. On August 4 they sprayed
from 8 am to 3 pm and on August 8 they sprayed from 9 am to 12:30 pm. On both days the
weather was sunny and calm and temperatures ranged in the 60's and 70's.
