A comparability agent, Combine, reduced the pH of the micro rate spray solution to pH 2.9 and did not reduce the amount of precipitate collected on the 100 mesh screen in the test system as compared to the micro rate without Combine. Quad 7 reduced the amount of precipitate on the 100 mesh screen probably because Quad 7 increased the pH of the micro rate spray solution. If nozzle and screen plugging persist, clean the sprayer and use normal herbicide rates. The micro rate system is not for everyone. Management requirements are greater for micro rates than for conventional rates.
Timing is critical.
Broadcasting the micro rate will have a similar cost compared to banding conventional rates.
