| Question: | "Our greens are creeping bent planted from stolons and contain also much annual bluegrass. Last season they suffered from brown-patch much less than the greens on several neighboring courses, a fact which we attribute to our having reduced the quantity of water and fertilizer applied to the greens. As an additional preventive measure this spring we limed the greens. Several of our neighboring courses use a power sprayer for applying mercury preparations in brown-patch control, considering this the best method of application. We are wondering whether, in view of the measures we have taken to prevent extensive injury from brown-patch, it would be advisable for us to go to the expense of purchasing a power sprayer for use in brown-patch control. The apparatus would cost about $900. In case we should purchase a sprayer, which of the mercury compounds could be safely used in it?" |

| Answer/Response: | "Any of the mercury compounds may be used in a power sprayer provided the tank contains a good agitator for keeping the mixture thoroughly churned during the application. There is a great deal to be said in favor of a power sprayer for applying mercury compounds. We do not regard it as the best means for applying those chemicals, but it is perhaps the most rapid means and is entirely satisfactory. There are several methods, which may be classified as best, though under somewhat different conditions. If by your method of handling the greens you find it is unnecessary to make frequent applications of mercury preparations it would perhaps not pay you to invest in an expensive spray outfit. If you can maintain your greens by the method you have used without relying on mercury treatments, we would advise you to continue with those methods. Chemical means of controlling disease we regard as emergency treatments. The situation is similar to that of human disease. There are persons who, in spite of everything they do to keep well, require frequent advice from physicians and frequent use of medicine, while there are others who, apparently without much effort, keep in good health without resort to medicine. Proper balance of food, exercise, and attention to other hygienic measures go far in preserving health. Where it has been found that it is necessary to apply mercury fungicides frequently in order to prevent damage from brown-patch, the power sprayer is undoubtedly the best means of application, since it does the work so much more quickly, and the overhead of the original cost is not such a big item." |
