118 INJURIOUS INSECTS OF 1903. 



Paris Green Resin Mixture — 



Resin stock solution, i gallon ; 



Water, 16 gallons; 



Milk of lime, 3 gallons ; 



Paris Green, ^-pound. 

 This is an excellent remedy for cabbage worms and 

 other caterpillars on cabbage, cauliflower or turnips. 

 Cauliflowers innst not be sprayed after the ''flower" is ex- 

 posed; cabbages may be sprayed when the plants are 

 one-third grown and again just before the heads are 

 formed. There is then no danger to the consumer from 

 such treatment. 



Bordeaux Resin — The Bordeaux Mixture is made in the 

 usual method (liquid form), then 2 gallons of the stock solu- 

 tion is added to every 48 gallons of Bordeaux, the whole be- 

 ing stirred. It is best to dilute the stock resin with 8 parts 

 of water before adding to the Bordeaux. That is, in pre- 

 paring a 50-gallon barrel of mixture, the copper sulphate 

 and lime are diluted enough to make 40 gallons, after 

 which 2 gallons of stock resin is diluted to 10 gallons and 

 then added to the Bordeaux Mixture. 



This is an excellent remedy for Asparagus Rust. 

 (N. Y. Exp. Sta. 188, 1900.)

This substance may be used against plant lice and 

 other soft-bodied sucking insects. It may also be used, 

 like the preceding substance, with Paris or Bordeaux, to 

 make these stick to glossy surfaces.
