Question: | "A new mercury compound has been offered to us for the control of brown-patch. It is said to contain 6 per cent mercury. This is claimed to be in a not completely soluble form and therefore superior to other mercury fungicides in that it does not wash out of the turf so readily and therefore is effective for a longer period. The claim is made that this preparation has resisted attacks of brown-patch for a period of 42 days. The names of 11 golf courses are given where the preparation has been successfully used. Have you any information that would indicate that such a preparation should be superior to other mercury fungicides used in the control of brown-patch?" |

Answer/Response: | "Having tested so many mercury compounds and found that they behave very much alike when placed on the percentage of mercury basis, we feel confident that the preparation you mention would prove to be no exception to this rule. The common success in the use of preparations for controlling brown-patch during the 1930 season, is due in great measure to the fact that the dry weather of that season made brown-patch much less of a troublesome pest, and it is entirely possible that injury from brown-patch during that season in many instances would have been no more extensive had no checmical remedies whatever been used. The fact that the preparation referred to has been known to remain effective for a period of 42 days does not constitute proof of its superiority over fungicides which have been known to be effective over shorter periods, since it is well established that the same treatment put on at two different periods in the season may vary in its lasting effect all the way from 2 days to 2 months." |
