open. This application will not only destroy many 

 of the curculio, canker worms and other leaf-eating 

 insects, but if done at just the right time the blos- 

 soms and blossom stalks can be coated with bor- 

 deaux, and can thus be saved from the attack of 

 fungi, to which they are subject if cold, wet 

 weather prevails. 



" A second application should always be made 

 within a week after the petals have fallen. In cases 

 where the first application was made at exactly 

 the right time and it has not been washed off it 

 will, perhaps, be fully as well to wait four or five 

 days after the petals of a given 

 variety have dropped, but it 

 should by all means be com- 

 pleted within a week, and the 

 sooner the better after the petals 

 are off, unless one can be sure 

 that the young fruits are well 

 coated with the fungicide. So far 

 as the codling moth is concerned, 

 the best time for making this ap- 

 plication will be after the stamens 

 have had time to dry up and be- 

 fore the calyx lobes close. 



" The third application should be made about 

 two weeks after the second, or within three weeks 

 from the time the petals have fallen, having in mind 

 the importance of keeping the fruit and foliage 

 covered with the spray mixture, and it may be 

 desirable in some cases to shorten the period be- 

 tween the sprayings. This will be made at about 

 the time that the first larvse of the codling moth 

 hatch. Eggs will have been laid upon foliage and 

 fruit over a period of perhaps three weeks, and will 

 hatch in about ten days from time they are laid.
