California Oak Worm (open access)

California Oak Worm

"The live oak and the valley oak, which are characteristic of the landscape of central California, often are stripped of their leaves by a dark-striped worm which is the young stage of a light-brown moth. Besides stripping the trees of their leaves and making the owner think that they are dead, the worm crawls on lawns, walks, fences, and into houses, swimming pools, etc., becoming a general nuisance.... This bulletin describes and illustrates the worm and its work, tells about its habits and natural enemies, and explains the methods of control." -- p. 2

The Eelworm Disease of Wheat and Its Control (open access)

The Eelworm Disease of Wheat and Its Control

Revised edition. "The eelworm disease of wheat, long known in Europe, has been found during the past year causing considerable damage in Virginia and in isolated localities in West Virginia, Maryland, Georgia, and California. Every effort should be made to control the trouble in these infested regions, to prevent its further spread, and to find other localities where the disease may exist. The disease may be recognized on young and old plants and in the thrashed wheat by the descriptions given in this bulletin. The trouble may be controlled by use of clean seed, by crop rotation, and by sanitation. If clean seed cannot be procured from uninfested localities, diseased seed can be made safe for planting by the salt-brine treatment here described." -- p. 2
