Rot, and the rotting of the fruit on the trees in the wann days of early 

 fall. This midsummer spraying is more important here than in some 

 other sections of the United States, and it is more needed in the warmer 

 sections of the State than in our highest and coolest locations. 



WHICH TREATMEJ^TS ARE MOST IMPORTANT ? 



The foregoing outline of five sprayings is for the man who wants the 

 best of results, and is willing to do the work to get the best returns. 

 But many will want to know which treatments they maj'^ leave out. Let 

 us see: The spraying just as the buds open (I^o. 2) reaches the least 

 number of important pests, and so may, perhaps, be omitted more safely 

 than any other. If you have no San Jose Scale, then the winter treat- 

 ment (No. 1) can be omitted, although it is better to give it anyway (at 

 least every two or three years), even if there is no scale. If you are not 

 troubled with Bitter Rot and the apples rotting on the trees, then you 

 can omit the midsummer spraying (^o. 5). The treatment that comes 

 three or four weeks after the blossoms fall (No. 4) can be omitted if 

 necessary. This leaves only one more, namely, the one just after the 

 blossoms fall (No. 3), and this is the one most important treatment for 

 every bearing apple orchard, for every such orchard is infested with 

 Codling Moth, Curculio, and leaf eating insects, and we simply must 

 give this treatment after the blossoms fall, if we are to have a full crop 

 of perfect fruit. Here is a statement of what we consider the relative 

 importance of the five treatments: 



First in importance — No. 1. Winter treatment, if there is scale. 



Second in importance — No. 3. Just after blossoms fall. 



Third in importance — No. 5. Summer spraying, if fniit rots on tree. 



Fourth in importance — No. 4. Three to four weeks after blossoms fall. 



Fifth in importance — No. 2. As the buds open. 



So it depends upon what your troubles are as to which of the treat- 

 ments you can afford to miss. If you have no scale, but have trouble 

 with fruit rotting on the trees, then you must give the summer treat- 

 ment, while you may leave out the winter one. But if you have scale 

 and do not have trouble with the rots, then you must give the winter 

 treatment and may omit the summer one. If you have both scale and 

 rot. then you must give both the winter treatment and the summer treat- 

 ment. But every bearing orchard has Codling Moth, Curculio, and leaf 

 eating insects which are reached by the treatment just after the blos- 

 soms fall (No. 3), so that stands out preeminent as the one treatment 

 that every bearing orchard should receive. 



Experience is the only teacher that can show to each and every 

 grower just what precise treatments he should use. One man will adopt 

 a regular system of three treatments, another two, another four, and 

 another five. But it is only the grower who studies for himself, and 

 who knows just what the most important enemies in his own orchard 

 are, who can hope to get the best results.
