SPRAYING MATERIALS AND DATES

Sucking Insects Chewing Insects Fungous Diseases 



Leaf Hopper Blue Beetle Black Rot 



Berry Moth Anthracnose 



Curculio Mildews 



Roootworm 



Leaf Hopper. Must be sprayed before young can fly, with 

 solutions of soap or oil. 



Blue Beetle, Berry Moth Larva, Rootworm, and Curculio 

 Larva are chewing insects, and are controlled by arsenate of 

 lead. First spraying for them should be before blossoms 

 come; second spraying after fruit sets, and third in July. Com- 

 bine the lead with a fungicide whenever possible. 



Black Rot. Attacks leaves first, then berries. Bordeaux 

 Mixture is the most effective remedy in most cases. Lime-sul- 

 phur in proper form, combined with arsenate of lead, should be 

 used oftener than it has been in the past. Spray first when 

 buds begin to open; second, just after new shoots appear, before 

 blossoms open; third and additional spraying should take 

 place every ten days or two weeks until five or six applications 

 have been made. If the disease shows near ripening time, use 

 ammoniacal copper carbonate, because it will not russet the fruit. 



Anthracnose. Difficult to control. Spraying material and 

 dates correspond to those for Black Rot, except that the work 

 should be done even more thoroughly. 



Mildews. Materials and dates for spraying the same as 

 for Black Rot. Two or three sprayings will control mildews; 

 first one before blossoms open; second, after fruit has set; and 

 third, ten to fourteen days later. 



PEAR 



The sucking insects, the chewing insects and the fungous 

 diseases which attack pear are practically the same as those 

 that attack apple, and are controlled by the same treatment. 

 Pear, therefore, need to be sprayed while dormant with con- 

 centrated lime-sulphur for controlling scales, when buds open 

 and when blossoms open with combined insecticide and fungi- 

 cide, and later, sometimes, with Bordeaux for rot. Pear foliage 

 is tough, and will stand strong sprays. 



PEACH

i San Jos6 Scale Curculio Leaf Curl 



I>canium Seal-; Scab 



Aphis Brown Rot 



San Jose Scale. Kill by spraying in dormant period with 

 concentrated lime-sulphur solution. Hold in check during 

 summer with self-boiled lime-sulphur or diluted lime-sulphur 

 solution to which is added arsenate of lead. 



[NOTE. Peach foliage is more tender than apple. All foliage sprays for 

 peach should be only from one-half to three-fourths as strong as for the 

 corresponding trouble on apple. This is very important, and must not be 

 overlooked.]
