spraying with lime-sulfur or Bordeaux at this time just be- 

 fore the bloom opens and before a rainy time, before the in- 

 fection can take place. 



Then, of course, the next spray after this is when the 

 petals have dropped or are just starting to fall otf and are 

 ready for the coddling moth. You are all familiar with 

 them, so I won't take any time on that. Two or three 

 pounds of arsenate of lead I believe is being most generally 

 used or the Bordeaux is used and a good many are using the 

 commercial lime-sulfur, which is diluted 1 to 40 in the case 

 of strong trees or 1 to 30 or 35 depending on the strength of 

 your home-made. This makes a black, bad looking mixture, 

 but it isn 't quite as bad looking to us as it is to the coddling 

 moth and it doesn't ruin the fruit so much as the Bordeaux 

 does in some seasons. If the canker worms are bad we ap- 

 ply another spray about ten days later of arsenate of lead 

 and Bordeaux or lime-sulfur, and for the apple scab. We 

 have to be ver^^ careful in this spray. There are some varie- 

 ties of apples, like the Ban Davis, which are very easily 

 marked with the Bordeaux injury and so these varieties will 

 require a weaker mixture than some of the others, and this 

 can only be determined by experiment in your own locality. 

 If the weather is rainy and damp it seems as if a very weak 

 solution will cause injury. If the weather is clear and sun- 

 shiny it can be used stronger. 



Perhaps we will go through with the apple spraying. 

 The last spraying is about eight or nine weeks after the 

 blossoms have opened, for the second brood of coddling 

 moths and any other leave-eating insects and some of the 

 later fungus troubles. That is the last spraying on the ap- 

 ples. 



Now, the peach spraying: "We have already sprayed 

 them in the spring with lime-sulfur or oil, for the San Jose 

 scale and the peach leaf curl. In damp seasons the peach 

 leaf curl is very serious and fully as important as the scale. 

 We spray every year, regardless of any scale or any fungus, 

 just to catch the peach leaf curl. When the buds are open 

 the little peach blossoms begin to drop away perhaps ten 

 days or two weeks after the bloom is open and we spray 

 with what is called self-boiled lime-sulfur or Scott Mix- 

 ture named after Mr. Scott of Washington. That is real- 

 ly not a boiled mixture. It is made by taking eight pounds 

 of the same cheap form of sulfur eight pounds of limey
