Preliminary Report on Controlling the Winter Emergence of the Japanese Beetle in Rose Greenhouses by Application of Chemicals to the Soil

Abstract

The Japanese beetle (Popillia japonica) may cause injury in greenhouses containing roses by emerging during the winter months and feeding on the plants. This paper gives preliminary results obtained in an effort to control this injury by treating with various materials, beds containing five varieties of roses. As roses are usually allowed to remain in beds for a period of three to four years, final data on the value of the various tests will not be available until the expiration of that length of time.
