 shallow so as not to cut many roots. Clover plowed under will gen- 

 erally seed itself. 



SPRAYING DISCUSSION. 



Mr. Glassmire — We have had good results from both kinds of 

 spray. Find dust excellent after a rain. Can use dust when can't 

 get on with liquid. Sprayed grapes with dust. No rot. 



Secretary Goodman — I know this orchard very well. Mr. 

 Tune took charge last year ; sprayed 40 acres with dust exclusively, 

 and he states that the liquid is rather more effective than dust, but 

 is going to continue the experiment. We can't draw conclusions 

 from any one year. Must continue experiments for some time. 



F. W. Faurot, Mountain Grove^ — We are not using dust this 

 year, as we couldn't get it made up when it should have been. We 

 wanted to use it and make comparative tests with the liquid. In 

 all work before this year our results are decidedly in favor of liquid 

 spray. 



Prof. Scott — If you do not leave any unsprayed trees when ex- 

 perimenting, you don't know if spray does any good or not. I sug- 

 gest that fruit-growers, when using any kind of spray, leave a few 

 trees, and at the end of the season you will have something to judge 

 by. You may lose a little fruit, but get much more in valuable ex- 

 perience. 



Secretary Goodman — We have used dust for the last four years 

 quite extensively, as we have 800 acres where we cannot get water 

 enough to spray them. For the last few years we have had no crop, 

 and can't see much result. It was the same when we began with 

 liquid sprays. We were disappointed, and have been with dust, but 

 know the work is being done. 



Mr. Johnson — Where dust is used five or six times we have 

 almost a perfect stand of apples. For the last four years over 800 

 acres of orchard were sprayed, some two, some three and four 

 times. Spray as soon as petals begin to drop, and keep up till last 

 of June or July. If we take a young orchard and begin with dust, 

 I am sure we are holding all those things in check. If we begin in 

 time, and while the orchard is reasonably free from disease and 

 insects, and use dust thoroughly till late in the season, we can keep 

 both fungi and insects in check. I am not ready to say that dust 

 is equal to the liquid. I don't believe it is, as with liquid we can 

 drench before the leaves start in the spring better than with dust
