San Jose Scale. 



I hardly need emphasize the importance or destructiveness of 

 this insect. It is a subject for a complete talk in itself, but I 

 will only speak briefly on it. In Ontario and Illinois I have seen 

 hundreds of acres of peach, apple and pear trees destroyed by 

 it. In my opinion it will some day, and that not distant, be 

 the great factor in reducing the export of apples from certain 

 • sections which are now producing a large proportion of our 

 apples. When that time comes, the growers who have sprayed 

 in those sections and all of the growers in sections that have 

 kept clear of the pest, will reap a harvest. 



The San Jose scale is perfectly controlled by one spray with 

 lime sulphur, i to lO, as you use for your blister mite. I can 

 take you to properly sprayed orchards in the Niagara district 

 or in Illinois, in the worst scale districts, where it will keep 

 anyone busy finding a single scale. In orchards near by you 

 can find trees dying from scale. San Jose scale, as many othef 

 serious pests, usually acts as a blessing to the careful orchard- 

 ist as he will spray enough to control the scale. The benefit he 

 gets from his dormant i-io lime sulphur spray in controlling 

 blister mite, a certain percentage of black spot or scab and 

 other pests, will usually more than pay for his spray; and the 

 fruit from the unsprayed orchards of his competitors will, to 

 a great extent, vanish from the market, making better prices 

 for his own. 



In Nova Scotia, I found the first scale in the province in 

 191 2 on recently imported nursery stock. After several meet- 

 ings and consultations, the growers there decided that they had 

 plenty of blessings in the shape of insect pests and, if there 

 was a possible chance of eradicating the scale it should be done. 

 I was placed in charge of the work for that season and our 

 inspectors destroyed over 700 trees, all recently planted. Since 

 that year a provincial entomologist has been employed who has 

 continued the work and this year his men have found only ten 

 trees infested, which have been destroyed, and we have great 

 hopes that he will be able to eradicate the scale from the 

 province. I merely mention this to show you that, should you
