Produce a potent, quick-acting, highly adhesive, 
mist-like spray. Will not hurn the tenderest leaf 
or flower. 
What we mean by COLLOIDAL: The Colloidal 
properties cause the Cartridges to dissolve into 
ultra-microscopic particles, which remain in suspen¬ 
sion while spraying, flow freely, and gives complete 
coverage and more lasting protection than non- 
colloidal materials.
