Currie's farm and garden annual : spring 1918 43rd year curriesfarmgarde19curr_1 Year: 1918 ( LIST OF INSECTICIDES AND FUNGICIDES 93 SprayiuK is an insurance, and every fruit-grower and gardener should insure himself' against failures in order to succeed. In some seasons spraying may seem useless, but the next season will produce results that will repay him for the at- tention given. Spraying must be done thoroughly to be ef- fective. It should not be done without the knowledge as to the nature of the insects and how they destroy. These may be divided into two classes, viz., (1) leaf eating, (2) sucking. Both require separate treatments. The leaf eating caterpillars, potato-bugs, etc., require a stomach poison, which is sprayed on to the plant and intended to be eaten. The sucking insects, plant lice, aphides, etc., require a contact poison such as the Tobacco Extracts, Kerosene Emulsion, etc., whereby their en- tire body is covered with an irritant and their breathing pores closed. The fungicides listed are to be used for plant diseases. The cheapest and most effective way to combat these is to spray early in the season and prevent same. Fruit trees, potatoes, tomatoes, beans, etc., thus treated will thrive, where others fall. 'Spraying Calendar' pamphlet sent upon request.
