Different Forms of K-L Mixtures. 



"K-L" as mentioned before is kerosene, lime and water. 

 This is an insecticide for sucking insects only. "K-L-B" is 

 kerosene, lime and Bordeaux mixture, and is worthy of trial 

 to destroy fungous diseases as well as sucking insects. This 

 is made exactly like "K-L" except that Bordeaux mixture is 

 used instead of water. "K-L-B-P" is kerosene, lime Bor- 

 deaux mixture and poison. It is miade like "K-L-B" except 

 that the poison, whether Paris green, disparene, arsenite of 

 Ume or soda, or green arsenoid, is added to the Bordeaux 

 mixture. This is a theoretical combination panacea for all 

 the ills and pests of the orchard, be they sucking insects, 

 biting insects or fungous diseases. It is worthy of serious 

 consideration and trial as a "Jack of all sprays." 



In making K-L with rosin soap a portion of the water 

 should be used to dissolve the soap. After the mixture has 

 been agitated two minutes the soap solution is added and the 

 entire lot is agitated one minute longer if limoid is used, and 

 three longer if other forms of lime are used. The directions 

 for adding rosin soap apply to caustic soda and salt also. 



Spraying During the Growing Season. 

 One fact to which your attention must be called was the 

 antagonistic behavior of the weather man toward these exper- 

 iments during the summer. Almost invariably when we 

 planned spraying work for the day he would marshal his 

 storm clouds and hold them in leash out of sight until the 

 spraying was done, then would turn them loose to deluge our 

 work. When we sprayed in the forenoon a heavy rain would 

 fall during the afternoon. When we sprayed in the after- 

 noon a terriffic storm would burst upon us during the night. 

 W'hile these weather conditions would not have been chosen 

 for the work, perhaps they were not amiss, since they made 

 the test a more severe one for the spray mixtures, and the re- 

 sults have more real significance than they would have had 

 in ideal sunshiny weather. 



For use during the summer it is safe to apply lo per 

 cent. K-L, with or without adhesives, to apples, pears, peach- 

 es, plums, cherries, quinces, currants, etc. From tests made 

 it seems perfectly safe to advocate I2j^ per cent. K-L on all
