I just bought 1 pound of Drive 75DF. Can you confirm that a level tablespoon equals 0.367 ounces? Also, for spot spraying, the label recommends 2 tablespoons (1 oz) of MSO per gallon of water. However, 0.55 oz of MSO is specified elsewhere.
Which is correct?
Thanks!

Trinity® herbicide Success Snapshot
Hendersonville Country Club- Hendersonville, N.C.
With gentle rolling hills and wide valleys, the Donald Ross designed Hendersonville Country Club is a picture of stress-free terrain. Unless you’re its superintendent.
The private, 18-hole, par-70 course in Hendersonville, N.C., hostsmore than 32,000 rounds of golf each year. Kirk McKinney joinedthe course in January 2007 as golf course superintendent, takingon the challenge of keeping the 1933 push-up greens healthydespite wear, tear and compaction from more than 70 years ofheavy traffic.
“Keeping water off the greens is crucial to prevent conditions fordisease,” McKinney said. “It’s also tough maintaining the course’sPoa annua as temperatures increase in the summer.”
Anthracnose had been a consistent summertime problem forseveral years.
“The turf was fine when I began working here,” McKinneyexplained. “But at the end of May, I saw signs of anthracnose onthe greens and we quickly lost five to 10 percent of turf on five orsix greens.”
The disease showed up as reddish-brown lesions ranging fromthe size of a pencil eraser to five to six feet in diameter in themost advanced areas.
Based on the course’s limited success at controlling the diseasein the past, McKinney knew he needed to modify the existingfungicide program.
“The other products weren’t giving us control and they werelosing their punch,” he said.
McKinney’s distributor recommended Trinity™ fungicide assafe to use during the summer stress period. Shortly beforehe planned to make his first Trinity application, McKinneyattended a distributor meeting for superintendents where BASFsales representative Willie Pennington gave a presentation onthe product. Because of the high temperatures in the area,Pennington recommended applying the fungicide at the lowerone-ounce rate, increasing the intervals to avoid turf damage.
McKinney prepared a tank mix of Trinity at a rate of one ounceper 1,000 square feet and Insignia® fungicide at a rate of .9ounce per 1,000 square feet to treat the anthracnose and controldollar spot. He applied the fungicides – along with fertilizer andgrowth regulator — in four spray applications, 30 days apart, onthe course’s greens, collars, and areas surrounding greens andapproaches. Between applications, he used other products withdifferent modes of action. As a cultural control, McKinney’s crewrolled greens weekly and moderated mowing heights.
