Volek is one of the most powerful insecti- 
cides known. It is effective on practically all 
insects on ornamental and flowering plants. 
Wonderful results have been obtained against 
red spiders, cyclamen mite, aphis (green fly), 
scale, mealy bugs, thrips, and caterpillars. 
Many pests that could not be controlled 
before are now killed with VOLCK. Even 
mildews and rusts are prevented and stopped 
by VOLCK. Not only does VOLCK give 
effective control of pests, but it also pre- 
vents reinfestation for a considerable period. 
VOLCK is odorless, colorless and non- 
poisonous. There is no unsightly residue. 
Plants are deep glistening green after using 
VOLCK. 
VOLCK IS SAFE AND SURE 
Tender foliage can be safely sprayed where 
VOLCK is used. Pests of coleus, cyclamen, 
evergreens, ferns, orchids and many other 
types of plants have been successfully con- 
trolled. VOLCK is the most effective remedy 
known for red spider on indoor vegetables. 
It is used because it is safe and sure.
