The Eelworm Disease of Wheat and Its Control
"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

The Wheat Jointworm and Its Control
Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, feeding on the juices of the plant and causing a slight swelling or distortion of the stem above the joint. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks wheat only. The injury which it causes to wheat is very distinct from that caused by the Hessian fly, yet the effects caused by these two insects are often confused by farmers." -- p. 1-2. This bulletin gives a brief outline of the life cycle and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended.
