Frost and the Prevention of Damage by It

Frost and the Prevention of Damage by It

Date: 1920
Creator: United States. Dept. of Agriculture.
Description: "All frost protection methods, from the simplest to the most complicated, can be carried on more successfully if the processes by which the earth's surface cools at night and the factors which influence the rate of cooling are well understood. In the first part of this bulletin an attempt has been made to describe in a simple, elementary manner the changes that take place at and near the earth's surface on a frosty night, so that persons protecting plants or trees may be able to understand how their protective devices operate to prevent damage and in what manner they are most efficient. In treating a matter of this kind it is practically impossible to eliminate all technical terms, but so far as possible these have been carefully explained in simple language. The larger portion is given over to a discussion of the various methods and devices now being used for protection against frost, together with a chapter on temperatures injurious to plants, blossoms, and fruit." -- p. 2

The Corn Earworm As an Enemy of Vetch

The Corn Earworm As an Enemy of Vetch

Date: 1921
Creator: Luginbill, Philip & Beyer, A. H. (Adolph Harvey), b. 1882
Description: "Vetch, which has become an important forage crop throughout the Southeastern States, needs protection from the same insect that works such havoc on corn and cotton. This corn earworm, or cotton bollworm, is the most serious pest that growers of vetch have to combat. The caterpillars eat both the foliage and the seed pods, and, if the infestation is heavy, make the crop practically worthless. Vetch intended for a hay crop generally escapes serious injury, as it is cut before the caterpillars are large enough to do much damage. It is recommended that a crop intended for seed be carefully watched and if the insects become numerous an insecticide be applied at once or the vetch cut for hay. Spraying, dusting, the use of poisoned-bran bait, and other control measures are discussed and summarized in this bulletin." -- p. 2

Green Manuring

Green Manuring

Date: 1922
Creator: Piper, Charles V. (Charles Vancouver), 1867-1926 & Pieters, A. J.
Description: "Green manuring means turning under suitable crops to enrich the soil. Such crops may be turned under green or when ripe. Green manuring adds organic matter and, directly or indirectly, nitrogen to the soil. Leguminous crops are most desirable for green manuring, since they add to the soil nitrogen gathered from the air in addition to the organic matter which they carry. Besides the nitrogen in the legumes turned under, an additional supply of nitrogen is fixed in the soil by the action of bacteria, using the carbon in the organic matter as a source of energy. Turning under an entire crop is advised only when the soil is poor and for the purpose of starting a rotation. Turning under catch crops or winter-grown green crops is an economical and successful method of supplying nitrogen." -- p. 2

Grasshoppers and Their Control

Grasshoppers and Their Control

Date: 1939
Creator: Parker, J. R.
Description: "Grasshoppers in a single year have destroyed crops valued at over a hundred million dollars. The best way to prevent losses is the use of poisoned bait supplemented by tillage and seeding methods which restrict egg laying and imprison the young grasshoppers in the ground after they hatch. Bait is most effective while grasshoppers are still on their hatching grounds or massed along field margins. It should be put out when grasshoppers are doing their first feeding of the day. This usually occurs between 6 and 10 a.m. at temperatures of 70° to 80°F. Bait should not be spread unless grasshoppers are actively feeding. In mixing and distributing the poisoned bait care should be taken to prevent injury to persons and farm animals. Seeding grain only on plowed or summer-fallowed ground and plowing infested stubble before the eggs hatch greatly reduces the quantity of bait needed for control and decreases the liability of crop injury. Cooperation in the use of control methods by all the farmers in a community is necessary for best results." -- p. i

How Insects Affect the Rice Crop

How Insects Affect the Rice Crop

Date: 1920
Creator: Webb, J. L. (Jesse Lee), 1878-1942
Description: This pamphlet discusses insects that damage rice crops: "The slender, milk-white grub or 'maggot' of the rice water-weevil lives on the roots of rice, and whether it feeds little or much upon them, kills practically all the roots that it attacks. This pruning of the roots weakens the rice plant and often kills it. Another enemy of this staple crop of the South is the stink bug, which sucks the juices from the soft grains of rice. The fall army worm, when it becomes abundant, works great havoc in its attack upon young rice. Other insects also, such as the rice stalk-borer, infest the rice field, and the rice planter must constantly guard his crop against them. This bulletin tells when to plant, and when to flood and drain the fields in order to reduce the numbers of these pests, and recommends other measures that will prevent attack by the many minor species of insects which normally breed in and near rice fields." -- p. 2
