SPRAYING EXPERIMENTS IN THE NIAGARA REGION 



PROP. W. LOCHHEAD, 0. A. C, GUELPH. 



THE most serious enemies of the fruit 

 grower in the Niagara region are the 

 San Jose scale, the cherry aphis, the codhng 

 moth, grape rots, the phmi rot and the apple 

 ■scab. 



For several years strenuous efforts have 

 iDcen made to control the San Jose scale with 

 such materials as whale oil soap, crude pe- 

 troleum, and the lime-sulphur wash. Suc- 

 cess has fdllowed the application of the lime- 

 sulphur wash in particular, but on account 

 of the trouble involved in boiling the wash 

 it was thought advisable to try a method of 

 preparation which does not require pro- 

 longed boiling by steam or fire. Besides, it 

 was deemed advisable to know the effective- 

 ness of certain new scale remedies which 

 have recently appeared, viz. : Capdson's 

 ; mixture, Pratt's Anti-scale Remedy or Scali- 

 •cide, and the kerosene-limoid mixture. 



The grape rots have also caused much loss 

 during the last three or four years. The 

 black rot is specially destructive in the St. 

 'Cath?jrines district, and promises to give 



much trouble in its control. The downy 

 and powdery mildews are the destructive 

 rots farther west in the Grimsby-Winona 

 district, and the grape growers in that dis- 

 trict are decidedly anxious as to the future. 

 The cherry aphis and plum rot are also diffi- 

 cult to control and cause much loss in many 

 orchards. 



The Minister of Agriculture, realizing the 

 serious nature of the attacks of these vine- 

 yard and orchard enemies in the great fruit- 

 growing regions of Ontario, decided to ar- 

 range for a series of experiments and 

 demonstrations this searson in spraying at 

 eight places from Winona to the Niagara 

 river. The main object of these experi- 

 ments and demonstrations is to test the ef- 

 fectiveness of the preparations which have 

 been recommended for the control of the 

 chief insect and fungous pests of the or- 

 chard and vineyard.
