CLOVER-LEAF WEEVIL IN IOWA 
129 
Two small alfalfa fields in Des Moines county were sprayed 
with arsenate of lead in much the same manner as is employed 
in the western states to control the alfalfa weevil. The county 
agent reported that apparently 90 per cent of the worms were 
killed in one field and that the alfalfa made an excellent recovery. 
The application of the poison was followed by rain at the other 
field and in consequence the results were not so favorable. 
For the most part no control measures were attempted. The 
weevil larvae are ordinarily highly susceptible to a fungus disease 
but during the season of 1921 much damage resulted before the 
fungus became operative and in some areas but a small percentage 
of the larvae seemed to be killed in this way.
