but found it very inconvenient to use on part of my orchard. The 

 last two years I appHed dust to about one-half of my orchard, 

 and cannot see any difference in the efifects of the two. Those sprayed 

 with dust are free from worms and fairly free from fungus, and about 

 the same with liquid. The most of the labor that we get for this work 

 is not of the most intelligent order ; with the dust spray they cannot do 

 any injury, and I find it cheaper. In applying the liquid, w'e work 

 from 7 a. m. to 6 p. m. In using the dust we begin as early as four in 

 the morning and work till 8 a. m. and from 6. p. m. till 9 or 10. The 

 foliage is covered with dew at these hours, and the spray adheres well to 

 both fruit and foliage. It will not adhere in the daytime, when it is 

 dry and windy. I have 800 acres in apples, and on the level land will 

 use the liquid and on the hilly land will use dust. 



Mr. Todd — I have used dust spray six years. Tried both liquid 

 and dust. I left two rows unsprayed, and found no difference be- 

 tween the two methods of spraying. I am only studying the best 

 methods to raise apples, and have made a success in growing this fruit. 

 I never had a real failure; once had a partial failure caused by hail- 

 stones. Expect to continue the use of the dust spray. Have been suc- 

 cessful W'ith it and do not care to change. 



Mr. Faurot, Mountain Grove Experiment Station — Have tried both 

 kinds of spray. The results of dust spraying show differences between 

 sprayed and unsprayed. We tried it at Fordland, Olden and Moun- 

 tain Grove, and used three formulas — Maxwell's, the one from Colum- 

 bia, and tried by Professor Bird, and one of our own. Spraying for in- 

 sects should be done just after the petals fall and while the embryo apple 

 still stands upright with the calyx not yet closed. After our experi- 

 ence, I certainly could not recommend the dust. In some of the experi- 

 ments we could see no diiterence between trees which were dusted and 

 those which were not treated at all. I believe that the dust process is 

 ineffective against fungous diseases. For codling moth, I can believe 

 that perhaps the first spraying, when the petals of the young apples are 

 open and the young apples are turned upward, will help to hold this in- 

 sect in check, but after the blossom ends of the apples turn down I don't 

 believe the dust will be effective against the codling moth.
