PLUM CURCULIO CONTROL 
CORN EAR WORM CONTROL 
; SOIL FUMIGATION 
A mixture of Dichlorethyl Ether and white mineral oil effec- 
tively controls the corn ear worm. Injection is made into the 
ear immediately following the completion of pollination. Ether 
fumes kill all stages of insect development—making possible 
increased production of hybrid corn and increased quality of 
sweet corn. 
Government agencies are now recommending a Dichlorethyl 
Ether emulsion as a dormant spray of the soil in the orchard 
for the control of plum curculio as an effective means of pre- 
venting the over-wintering of this destructive pest.
