1. It is recommended that the method of control of the boll weevil ( A nthonomus grandis ) as described by the Southern Agricultural Workers Association, using calcium arsenate as a dust, or in special cases as a syrup mixture, be strictly adhered to for the time being. 2. Sodium fluosilicate, and possibly cryolite and barium fluoride, volume for volume, are equal or very nearly equal to calcium arsenate as a posion for boll weevil control. These substances should be subjected to further careful and extensive field tests to determine their exact value, using 10 to 15 pounds per acre. Every effort should be made to decrease the density of these poisons, and as the density of the poisons is lessened, the amount used per acre can be decreased. 3. It is believed that an advantage will be gained if the percentage of arsenic in calcium arsenate is reduced and a larger amount per acre used. Careful field tests should be made to establish definitely the value of this suggestion. 4. It seems quite possible that arsenic trioxide absorbed on coal dust or similar vehicle will make an effective and cheap poison for use against the boll weevil if some agent, such ,as an oil, is used to prevent plant burning. One and one-half per centarsenic trioxide on coal dust only shows occasional burning. It is. recommended that field tests using this amount of arsenic trioxide on coal dust at the rate of 10 to 15 pounds per acre be tried. Other powerful poisons should be investigated as to their possible use in this way. Probably a similar trial with arsenic pentoxide is worth while. 5. High concentrations of toxic gases are ineffective against the weevil due to the apparent ability of the weevil to suspend breathing more or less at will. There is still a possibility that low concentrations of a persistent cumulative gas may give an effective control. Some further research work along this line has yet to be undertaken.
