WINTER MEETING. 227 



to scorch the foliage ; it scorches the foliage of plums, too, to a certain 

 extent. Some friends claim that it preserves the plum crop. 



S. Miller — I tried it, but with no success. I ruined the foliage, 

 and could not see a particle of difference between the sprayed and the 

 unsprayed trees. 



Mr. Espenlaub — I am satisfied that spraying the grape will keep 

 down the mildew and black-rot. 



D. A.. Robnett sprayed 10 or 12 times against grasshoppers with 

 kerosene emulsion, but it did no good. 



S. W. Gilbert sprayed his peaches in the spring when they were 

 the size of peas ; sprayed four rows, waited 10 days, then sprayed eight 

 rows ; waited a week later and sprayed six rows. Those sprayed first 

 lost a little foliage ; the second spraying lost one-half the foliage and 

 some fruit ; the last six rows sprayed lost every leaf the spray touched 

 a,nd four-fifths of all the fruit. I used 4 lbs. sulphate copper, 4 lbs. 

 lime and 4 oz3. Paris green to 50 gallons water. 



Mr. Goodman — You used four times too much Paris green. Four 

 oz. is altogether too much. Two oz. is enough for apples, one oz. 

 for peaches. Test your mixture a day or two beforehand and see if it 

 will injure your trees. Friend Gilbert lost $1000 by his experience. 



Mr. Gilbert — The bulletins I had read said they had used the dilute 

 Bordeaux mixture with four ounces of green to 50 gallons without in- 

 jury to trees. There is something wrong there. The older the leaf 

 the greater the injury. I don't believe that six ounces would kill the 

 leaf just out of the bud. You have to wait till the sun shines to see 

 what effect your spray will have. 



Miss Murtfeldt — The young leaves are somewhat protected by a 

 kind of varnish, so they are not so easily injured as older ones. 



Mr. Espenlaub — I think many authorities have come to the con- 

 clusion that they have been recommending too strong mixtures. 



Prof. Whitten — Our season was very rainy, and there was hardly 

 enough fruit to make a test. My experience would recommend for the 

 apple, four pounds copper, four pounds lime, 50 gallons water. For 

 the peach and plum, one-half as strong, with one ounce of Paris green. 

 I tried only one plum and one peach tree ; some of the leaves dropped. 

 In case of the pear, there was perceptible benefit. There is very little 

 good in spraying kinds of apples the calyx of which remains closed. 

 The trees we sprayed were old and weak. It could hardly be called a 

 fair test. The spray was of some benefit in preventing rust of the leaf. 



C. A. Kefifer — The past year I sprayed grapes; I first used one 

 pound blue-stone to 10 gallons of water ; with this we sprayed vines 

 ^nd trellis before the leaves opened. Afterward we used one pound
