and leave it for six hours. This drug and its gas are explosive, so 

 keep fire away. It will form gas which will kill the weevils, but 

 the liquid should not touch the seed. If the land grew "buggy" 

 peas last year raise a few very early peas first to be destroyed 

 when nearly mature and the weevils get onto them. 



Cabbage Aphis 



(Aphis brassicae) 



This aphis or plant louse is often very bad on cabbages, but a 

 spray of tobacco extract (1 part of tobacco extract to 50 of water) 

 will control it well. The State Insectary will send you a parasite 

 for it if application is made. Before planting, dip all young cab- 

 bage plants in a solution of whale oil soap, 1 Ib. to 5 gallons of 

 water. 



Norfolk Pine Scale (Eriococcus araucariae) 



Norfolk Island Pine Scale 



(Errococcus araucariae) 



This is a pure white oval scale, much rounded over the top and 

 located at the base of and on the spines or leaves of the Norfolk 

 island pine. On crushing, they yield a yellowish, red fluid, and 

 seem to resist oil and caustic sprays ; but good results are reported 

 from the use of resin wash which seems to kill them.
