The sugarcane borer (Diatraea saccharalis crambidoides Grote) inflicts an average damage of about 20% on the sugarcane crop in Louisiana. No practicable plantation methods for controlling this pest have become adopted or practiced to any considerable extent by the cane growers. Insecticidal- treatment with arsenicals appears to be ineffective. The recent development of the insecticide dusting airplane has provided a practicable means for treating such a crop as sugarcane, and applications of sodium silicofluoride have given a fairly satisfactory degree of control of the borer larvae, including the first and second stages while they are feeding in the leaf roll and the older . stages even after they have bored into the heart of the cane. In the treatment of thirteen hundred (1300) acres of cane by this method in 1926, the borer infestation appears to have been reduced by 60% from a single application and where observations were made about six weeks after the treatment. This allowed time for one more generation to develop. A dosage of from fifteen (15) to twenty (20) pounds per acre was required. These results are considered very encouraging and the work will be continued in 1927.
