Remarks 



Mix 7C and 2. 



Applications for cur- 

 culio must cover every 

 twig, leaf and fruit, as the 

 insect feeds and lays eggs 

 for an extended period. 

 Cultivate the soil to a 

 depth of 2 inches under 

 trees, for a period of five 

 weeks after full bloom of 

 trees. Larvse are chang- 

 ing to beetle s under- 

 ground at this time and 

 are destroyed by destruc- 

 tion of cells in which they 

 rest.

Bark beetles, common 

 to everything, are pre- 

 vented by painting trees 

 with number 10. Apply 

 just before first warm 

 days of spring. Cut out 

 branches already infested 

 and burn. Apply wash 

 again two times during 

 the fifth month later, anc 

 again two times during 

 the third month later 

 than this. If this beetle 

 is detected at once it may 

 be destroyed by touching 

 the holes of entry with a 

 sponge soaked in kero- 

 sene.
