Factors Affecting the Efficacy of Fungicides in Soil

in soil. Although perhaps 20 years ago little was known about soil fungicides, a great deal is now known, as attested by an article of 93 pages and 600 references (33) , and an annotated bibliog raphy (98). Much of the information concerns insecticides and herbi­ cides, but is readily applicable to fungicides. While some fundamental ad­ vances follow empirical discoveries, experiments based upon fundamental in­ formation are more apt to lead to success. For this reason a brief review of some of the fundamental knowledge of soil pesticides is presented here. A list of chemicals discussed, and their names or abbreviations used in the text will be found in Table 1.
