The Larger Corn Stalk-Borer (open access)

The Larger Corn Stalk-Borer

This report discusses a pale, dark-spotted caterpillar known as the larger cornstalk-borer which bores into and weakens cornstalks. "Only corn is injured seriously by this insect; some of the larger grasses are food plants, and sugar cane sometimes is damaged slightly. This bulletin gives the life history of the insect, its feeding habits, and methods of combating it. There are two generations in a season, so greater vigilance is necessary. The second generation passes the winter only in the corn roots, so if these are destroyed or plowed under deeply, the pest will be largely decreased. The injury is worst where corn follows corn, so rotation of crops will help to destroy the pest." -- p. 2

The Larger Corn Stalk-Borer

Revised edition. This report discusses a pale, dark-spotted caterpillar known as the larger cornstalk-borer which bores into and weakens cornstalks. "Only corn is injured seriously by this insect; some of the larger grasses are food plants, and sugar cane sometimes is damaged slightly. There are two generations in a season. As the second generation passes the winter in the corn roots, if the roots are destroyed or plowed, the pest will be largely subdued. The injury is worst where corn follows corn, so rotation of crops will help to destroy the borer. This bulletin gives the life history of the borer, its feeding habits, and methods of combating it." -- p. ii

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

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

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria (open access)

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria

From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

Eradication of Ferns from Pasture Lands in the Eastern United States (open access)

Eradication of Ferns from Pasture Lands in the Eastern United States

"There are nearly 7,500 recognized species of ferns in the world, of which number over 200 are known to be native to the United States. A few species have become weed pests in this country, and it is to a discussion of the control of these weedy ferns that this bulletin is devoted. The parts of the United States in which ferns are bad weeds are, principally, (1) the hill country of the Northeastern States and the higher portions of the Appalachian Mountain region as far south as Georgia, and (2) the Pacific coast country west of the Cascade Mountains.... This publication deals only with fern eradication in the Eastern States." -- p. 1-2
