The Edward Fred Knipling Papers are part of the Screwworm Eradication Program Records in the Special Collections of the USDA National Agricultural Library. The Knipling papers cover the areas of entomology researched by Knipling during his career with the U.S. Department of Agriculture (USDA), including his early research on the screwworm and the eradication efforts in Curacao, Netherlands Antilles, and the Southeast United States in the 1950s. Knipling's research included parasite control methods and studies on the boll weevil, fruit fly, tsetse fly, European corn borer, and various species of ticks and moths. In addition, the collection reflects Knipling's continued activity in entomology after his 1973 retirement from the USDA. Materials include correspondence, publications, manuscripts, reports, photographs, research data, notes, speeches, awards, artifacts, and biographical information.

The control of the codling moth and the apple scab Full text

1906

Marlatt, C. L. | Orton, W. A. (William Allen)

"The codling moth or apple worm and the apple scab have no direct relationship except that both attack the apple and are, respectively, the chief insect enemy and the chief fungous disease of this fruit. Both are, however, subject to practical control by sprays, which being necessary at the same dates, in the main, can be combined in single applications, and it is for this reason that they are considered together in this bulletin. A brief life history is given of the codling moth, with a description of the sprays and other remedies for it, followed by similar matter on the apple scab. The bulletin concludes with a joint consideration, for both pests, of spraying outfits and methods, with directions for the combination of the spray mixtures, and a spray calendar"--Introduction.
