368 Report op the Horticulturist of the 



grower has to contend with. The trunks of the trees should be 

 examined carefully in spring and fall and the borers dug out. 



Yarious other remedies have been advocated from time to time 

 but none of them take the place of the examination of the trunks 

 and the removal of the insect as above advised. Mr. C. K. Scoon 

 of Geneva, N. Y., finds that strips of tarred paper tied carefully 

 around the trunk of the tree have given encouraging results as a 

 preventive of attacks of borers. The strips of paper are about eight 

 inches high, the low^er end being covered with earth. The paper is 

 tied firmh' in place encircling the trunk and tied at the top so tightly 

 that insects cannot pass between it and the bark. Should creases or 

 crevices occur in the trunk under the paper, sticks or twigs are 

 driven between the string and the paper so as to force the paper 

 tightly against the bark. The trees are examined for borers the 

 same as before. 



Codling Moth. — This insect is the same as that which causes 

 wormy apples and pears as previously described, see p. 349. It 

 should be treated by spraying with Paris green or London purple as 

 soon as the fruit sets, followed by one or two later applications at 

 intervals of ten days, or even less if heavy rains fall in the mean- 

 time. The poison thus used is also recommended for the curculio 

 mentioned below. It may be combined with Bordeaux mixture 

 when that is used against fruit spot and leaf blight, using one 

 pound for from one hundred and fifty to two hundred gallons. 



Curculio. — This insect, somewhat larger than the plum curculio, 

 feeds on the quince and also deposits its egg in the fruit. The egg 

 hatches and the larva burrows into the fruit, but according to Saun- 

 ders does not enter the core. 



Remedy. — Spraying with Paris green or London purple as for 

 the Codling Moth mentioned above, is recommended for trees that 

 are headed quite low. This system of training is commonly adopted 

 in large orchards and jarring such trees is a rather slow and expen- 

 sive operation. No carts adapted for jarring quinces have yet been 

 devised, so that thorough spraying with Paris green or London purple 

 appears to be as effective as any treatment that has yet been tried.

Anthracnose. — This disease is very common to both raspber- 

 ries and blackberries, but is most injurious to black raspberries. 

 It lives over winter in the canes and begins its attack on the new
