Remedies. Preventive remedies are the best. Destroy affected 

 leaves and worthless fruit by fire or otherwise. Spray affected 

 trees with Bordeaux mixture or ammonio-carbonate of copper, late 

 in the winter, after pruning. Again, at half -strength, while the 

 leaves are appearing and as the blossoms begin to unfold from the 

 buds, and again as the blossoms fall, and fourthly , when the fruit is the 

 size of marbles. At that time loz. of Paris green in 12 gallons of 

 the Bordeaux mixture will hold the codlin moth in check where this 

 troublesome insect has established itself. It is important that the 

 early sprayings should be made as directed. In bad cases an extra 

 spraying is given a few weeks after the one given whilst the 

 blossoms are falling. Do not neglect the trees during an " off " 

 year because there is little fruit, the spores, living and thriving on 

 branches and leaves as well, will cause great loss the following 

 season.
