The best time to apply the resin-lime mixture is when the 

 plants have only five or six leaves; theii, if necessary, follow with 

 two more applications to the top lea^'es before the heads are 

 one-half formed. This mixture should not &e used on cabbage aftei- 

 the heads are two-thirds formed. 



Experiments. 



The following tests of the poisoned resin-lime mixture have 

 been made. The tests were made on two separate farms, one- 

 half acre of cabbage being used on each farm. 



The first test was made on medium late cabbage, a mixture of 

 Savoy, Red Dutch and Flat Dutch, part of whioli had commenced 

 to head. 



August 26 — 1. Sprayed six rows with the poisoned resin-lime 

 mixture. 



2. Sprayed six rows with Bordeaux mixture. 



3. Sprayed six rows with poisoned Bordeaux mix 



ture. 



4. Sprayed two rows with poisoned resin mixture. 



5. Sprayed two rows with a poisoned Bordeaux 



mixture plus resin mixture. 



Note — The Bordeaux mixture used alone adhered only in the 

 folds of the Savoy cabbage. Where the resin mixture was com- 

 bined with the Bordeaux mixture it adhered as well as the resin- 

 lime mixture. 



September 4. Resprayed the above field, api^ying the same sub- 

 stHuces and in the same manner. 



Note. — The cabbage on Nos. 1 and 5, have nearly perfect foli- 

 age. Only a few cabbage loopers to be found and practically 

 none of the imported cabbage-worms. No distinguishable differ 

 ence between cabbage on No. 2 and on check. All badly eaten 

 and both kinds of caterpillars numerous. Condition of test No. 

 3 little if any better than No. 2. 



On August 31 the owner of the above field treated an adjoining 

 field with salt. When examined September 4 not a dead worm
