| Question: | "What are your recommendations for ridding putting greens of earthworms?" |

| Source of Question: | Ohio |

| Answer/Response: | "The quickest way to rid putting greens of earthworms is to apply bichloride of mercury, mowrah meal, or one of the commercial preparations on the market. Bichloride of mercury is very effective and often the most economical. It is applied at the rate of 3 ounces to 1,000 square feet. It should be mixed, with dry soil or other inert material and applied to the surface. Immediately after it is applied it should be watered into the soil, using a fine spray, care being taken not to water so heavily as to cause puddles to occur on the green, for in these puddles the chemical would tend to accumulate in stronger solutions. It is safest to use bichloride of mercury in the spring and fall. During summer the rate should be reduced somewhat to avoid burning the grass. Mowrah meal is used in the same manner, except that 15 pounds is required for 1,000 square feet. On a good many soils, however, complete control of earthworms is maintained by keeping the surface soil poisoned with arsenate of lead. This chemical, when properly applied, does not injure the common putting green grasses, and remains active in the soil for a year or more. The usual rate of application is 5 pounds to 1,000 square feet. After the surface soil of a green has been poisoned it is a common practice to add enough arsenate of lead in each top-dressing to equal the addition of 5 pounds of arsenate of lead a year. It is usually mixed with some inert material before being applied so as to assist in obtaining even distribution. It is generally watered into the turf after being applied; this is, however, not necessary unless there is danger of the material being wasted by wind, since when applied at the rate mentioned it will not burn turf grasses." |
