Τ KILLER ! . . . is effective w h e n applied in d o s e s a s small as o n e o u n c e o f pure S Y S T O X per acre. . . . can be effectively applied to seeds before planting, thus protecting the young plants for a considerable p e r i o d . S Y S T O X also appears to be effective in c o n t r o l l i n g many c o m m o n insects which attack fruits, vegetables, grains, forage crops, sugar and tobacco, and its ultimate use o n these c r o p s is indicated. Research also indicates that o n l y harmless traces of S Y S T O X residue—measured in tenths of parts-per-million— remain in the harvested crops. Approval for the initial use of this amazing new insect killer marks a significant milestone in the fight of this nation's great agricultural and chemical industries against destructive insects. Because of its vital importance, we are immediately making SYSTOK available to cotton growers i?i commercial quantities through our established outlets. SYSTO'K. will also be available to research organizations for experimental use 071 other crops.
Y S T O X , a revolutionary n e w type o f insecticide, Has just been approved for the control of aphid and two-spotted spider mite o n cotton. U n c h e c k e d , these killers could destroy the nation's cotton crop. S Y S T O X is the nrst true systemic insecticide ever approved for use in this country. Its dramatic method o f contarol p r o m i s e s e n o r m o u s n e w benefit to American agriculture. At>sorh>ed a n d translocated through foilage and roots, S Y S T O X renders plants highly toxic to many destructive insects for a considerable period of time. Approval of S Y S T O X for controlling these cotton insects climaxes three years of intensive research by t h e Pittsburgh Agricultural Chemical Company and its a s s o c i a t e , Chemagro Corp., f o l l o w i n g its original development by Farrbenfabriken. Bayer, Germany. Results of this work indicate that SYSTOX . . . . . . renders most plants toxic to insects three t o four times longer than conventional insecticides.
