Winter Meeting. 205 



common Avashing soda as possible in six gallons of water, then add one 

 gallon of ordinary soft soap and one pint of ci-iide carbolic acid and 

 tboronglily dissolve ; slack a quantity of lime in four gallons of water so 

 that when it is added to the above, the whole will make a thick white- 

 wash; add this to the above and mix thoroughly, and finally add one- 

 half pound of Paris green or one^fourth pound of powdered white 

 arsenic and mix thoroughly. Apply by means of a whitewash brush. 



The leaf crumpler can be picked off a few young trees by hand 

 during the winter, but if they be in large trees and a large orchard it 

 is better to spray wath the arsenite soon after the tree begins to leaf 

 out, using one pound of Paris green or two quarts of arsenate of soda 

 in one hundred and fifty gallons of water. 



The leaf folder can be killed bv the above method also, but should 

 be watched so as to begin spraying just as soon as the larvae hatch and 

 before they curl up the leaves. 



The canker worm is easily killed by the above method, and 

 spraying should begin as soon as the larvae appear, otherwise they may 

 defoliate the trees in a few days. 



The web-worms and tent caterpillars are better destroyed by 

 means of a torch applied in the late evening when the larvae are all 

 collected in their nest. 



The ISTew York weevil and the imbricated snout beetle can be 

 killed, but not successfully by spraying with the arsenite. 



The twig pruners, girdlers and borers can not be prevented, 

 but may be lessened by gathering and burning the fallen twigs. 



The climbing cut-worms may be prevented from getting up the 

 trees bv tving cotton wool about the trunks. 



The codling moth can be largely controlled by spraying with the 

 arsenates using one pound of Paris green or two quarts of arsenate of 

 soda (plus lime in all cases) in one hundred and seventy-five gallons 

 of water. The first spray should be applied about one week after the 

 flowers (petals) fall and then every eight days for four sprayings. If 

 it rains at any time during this, repeat the spraying and do not count it.
