PART II. 



I. A SPRAYING MIXTURE FOR CAULI- 

 FLOWER AND CABBAGE WORMS.* 



F. A. SlRKINE. 



SUMMARY. 



This mixture should be called resin-lime mixture. 



The tests made with resin-lime mixture and Paris green show 

 that late cabbage and cauliflower can be protected from the at- 

 tacks of the cabbage worm and the cabbage looper by two spray- 

 ings. 



The tests also show that in the case of cabbage the yield can be 

 increased 60 per cent to 100 per cent. 



The cost per acre will depend upon the number of acres sprayed, 

 the cost of spraying 10 acres twice being about $20.00. 



A power sprayer cannot be used to apply the above mixture to 

 cabbage and cauliflower. 



Only skilled workmen should be trusted with the spraying of 

 cauliflower. 



The resin-lime mixture with an arsenite added must not be ap- 

 plied to cabbage after the heads are two-thirds formed nor to 

 cauliflower after the " flower " is exposed.
