Prairie provinces. - On the prairies, a dust composed of 1 part of arsenate of lime or Paris green to 10 parts of hydrated lime is recommended. In areas where there is no dew, white arsenic can be substituted for arsenate of lime and used at the same strength. In Alberta, arsenate of zinc has given excellent control when diluted with hydrated lime or flour, at the rate of 1 to 10.

Book excerpt: Excerpt from The Colorado Potato Beetle, (Leptinotarsa Decemlineata Say) Domestic fowls are of some assistance in destroying this pest. And of these the duck early took to this insect, which is distasteful to some other fowls. For some time after the spread of the Colorado beetle to new territory chickens did not attack it, presumably because it has, in common with many other leaf-beetles, a nauseous taste. For sev s°al years, indeed, it was believed to be actually poisonous. After a time, however, chickens became better acquainted with this insect and began devouring its eggs and afterwards the larvae, finally eating the beetles with apparent relish. Skunks and snakes are reported to eat the beetles, and toads frequently gorge on them. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Potato Flea-Beetle (Epitrix Cucumeris) Though the adult insect has long been known to entomologists it is only within the last few yea-rs that we have learned that the larvae live in the ground feeding on the roots and tubers of the potato and perhaps on related plants. It is true that both Fitch and Riley stated more than 40 years ago that the larva is a leaf miner but it seems that their statements are based upon inference rather than upon actual observations.

Pea vines (see insectary notes) it might be advisable, if the trouble continues to be seriously prevalent, to Omit the peas from the rotation scheme. For potatoes upon numerous 20 to 60 - acre fields one year and peas over the same area the next would seem to Offer an unbroken opportunity for the growth of the summer genera tions of this destructive plant louse. This suggestion does not touch the question of the winter host, because it would be upon these vines as upon the potato that the summer genera tions would occur, and even if eggs were deposited upon the pea, as it is harvested with the oat crop it could not serve as a dangerous winter host.

Download or read book Disease Resistance of Potatoes Classic Reprint written by Lewis Ralph Jones and published by Forgotten Books. This book was released on 2018-03-18 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Disease Resistance of Potatoes The potato is one of the most important food crops Of the United States. It is, moreover, one which is subject to a number of serious plant diseases. Some of these, notably the late-blight, can be con trolled. By spraying. Yet this remedy is not applied by all farmers, and the annual loss amounts to many millions of dollars. Other dis eases, like dry-rot and the bacterial blight, are not controlled by spray ing and require a different line'of treatment. The subject of disease resistance in plants has received increased attention of late, and it is likely that the introduction of disease-resistant varieties of potatoes by supplementing spraying and special cultural practices, will be Of great practical value in lessening the Waste caused by disease. Although but little has been done in the United States toward secur ing varieties resistant to disease, the attention of potato specialists in other countries has already been directed toward this aim. AS a preliminary step in our work, Dr. L. R. Jones, botanist of the Vermont Agricultural Experiment Station, . Was commissioned to inquire into the occurrence of potato diseases abroad and the methods employed for their control, particularly with reference to the produc tion Of disease-resistant varieties. Doctor Jones spent six months from April to September, 1904 - in this work. In the course Of Doctor J ones's European itinerary, information of more or less value was secured at the following places, successively, and this was supplemented by a considerable correspondence covering a somewhat Wider area: Marseille, Naples, Florence, Munich, Halle, Berlin and vicinity, Dresden and vicinity, Bonn and vicinity, Wagen ingen (holland), Amsterdam and vicinity, Gron-ih gen, Delft, Gembloux (belgium), Paris and vicinity, London and vicinity, Reading, Cam bridge, and Edinburgh and vicinity. The thanks of the Department are accorded to the various Officials and other botanists in the coun tries visited, whose uniform courtesies made possible the success Of the mission.
