That the Siberian crab apple tree does not make a good stock upon 

 which to graft the varieties of our larger apples ; 



Tiiat girdling the grape vine during the season of 1890 in Dr. 

 Fisher's vineyard resulted in a weakened growth and a diminished

OUTLINE OF PLANS FOR USING FUNGICIDES AND 



INSECT1CIDP:S for 1892. 



for the apple. 



Spray for the destruction of the spores of the apple scab, and leaf 

 blight, with sulphate of copper, (Blue Vitriol;, one pound to twenty- 

 five gallons of water, or sulphate of iron (Copperas) one pound to 

 two gallons. 



For the destruction of the tent caterpillar, canker worm and bud 

 moth use the Bordeaux mixture, one-half strength, with Paris green, 

 one pound to 150 gallons, just before the blossoms unfold, and .for • 

 the same and the codling moth, as soon as the petals have fallen. 



Make a third application of the Bordeaux mixture nnd Pans green 

 in about two weeks from the time the petals fall should there have 

 been heavy rains since the last application ; then use the ammoniacal 

 carbonate of copper, one pound to fifty gallons of water, at intervals 

 of from two to four weeks, according to the weather, until the middle 

 of August. 



We would recommend the trial of sulphate of copper, one pound 

 to 500 and 800 gallons of water, after the middle of June. Should 

 no rain occur after the use of any fungicide or insecticide no further 

 application need be made until it does rain, .but if the interval has 

 been long, spraying should immediately follow a heavy rain. 



FOR THE PEAR. 



For the pear scab, leaf blight and cracking of the fruit, and cod- 

 ling moth, the same treatment should be given as for the apple, 

 except that no Paris green need be used until after the petals have 

 fallen, and only two applications of that need be made. 



If the pear tree psylla should appear, spray the trees thoroughly 

 with the kerosene emulsion (see page 24), one part to twenty parts 

 of water.
