The work of three seasons at the Louisiana Experiment Station has yielded consistent results showing that it is possible with a water-soluble dust like sodium silicofluoride to destroy at least half of the sugarcane borer larvae occurring on the exterior or burrowing through the interior of the stalks of corn or sugarcane which are the principal host plants of this species in Louisiana. With many of the more than fifty (50) materials tested thus far there has been a degree of burning of foliage of corn which is serious, but on cane which is much more resistant to chemical burn, a number of materials have been found safe and effective enough to justify extensive field applications which may at least supplement other measures in controlling this pest.
