Experiments with fungicides.
( 2017-07-20) Pammel, L. ; Extension and Experiment Station Publications

In Bulletin No. 16* of this Experiment Station, we reported an experiment in trying to prevent wheat rust. The three common species of rust occurring on our wheat and oats in Iowa are, Covered Rust of Wheat (Puccinia rubigo-vera), Common Grass Rust (Puccinia graminis), and Crowned Rust (Puccinia coronata).

Corn insects. Their injuries and how to treat them.
( 2017-07-20) Osborn, Herbert ; Extension and Experiment Station Publications

The corn crop is one of the most important crops of the state, and will doubtless remain so for many years to come. It is, therefore, of importance to know something of its insect enemies and the method of treating them. From the nature of the injuries to corn, particularly on account of the difficulty of any direct examination of some forms, and the difficulty of making any exact estimate, their injuries are, I think, very generally under-estimated. Probably the most serious losses come from those working under ground, the injuries of which are to be found simply in the lessened crop, and which consequently pass unnoticed by most farmers. At times the destruction of seed in the ground by wire worms, or injury to the newly sprouted plants by cut worms, wire worms or sod worms, which necessitate replanting, attract general attention. Sometimes, also, the general destruction of the crop by the corn root worm is noted, but when any or all of these insects simply destroy undeveloped plants or parts of plants, or when there is a gradual drain upon the growth of the plant, as occurs from the presence of the root lice in corn fields, it is naturally unnoticed, and the shortage in the crops is.charged to other agents.
