 ton,' Program For 1924

Methods approved by agricultural college and experiment station au- thorities for fighting the boil weevil were presented before the agricultural leaders of the south Wednesday aft ernoon at the session of the South ern Aericultural Workers association, in the Tutwiler hotel, Birmingham, and were formally adopted at the night session!
 pr. J. E. Hinds, state entomologist of Alabama, and officials and research workers representing Is cotton states were present.
 Among them were N. E. Winters of Florence, N. C.; R. E. Leily and J. A. Harris of Raleigh. N. C.: E. H. Barber of New Orleans; J. A. Moore of Birmingham; Clay Lyle of Agri- cultural College, Miss; Dr. W. Newell, director of the Florida experiment station at Gainesville, and Prof. D. R. Coker. a,
 It was the annual meeting of the organization. The program for boil weevil control in 1924 submitted, based on the reports of the eXperi- ment stations, was as follows:
 Not more acreage, but more cotton 
 by the committee studying the eco homie phase of cotton production in 1924. Only by the use of every means of efficiency, it was claimed, could the south produce cotton in way to continue it's domination of world pro- duction.t
 The report of the entomologists on holl weevil control. as adopted, was as follows;
 Pre-susare Peisonins. .4.v s 1. One pre-square poison aplicstion wherever hibernated weevils sf are fairly abundant (twenty or more to the acre.9 This application to be made just when squares begin to form.
 For sthis single treatment either home mixed rmolasses-calcuim ar senate hfxture may be used or straight ca1cuim arsenate dust. The molasses, mixture of one pound cal and one gallon water Is recommended for general conditions, but in case of extremely heavy infestation and with freuuent rains stronger and more expensive mixture may be -used' con taining two pounds calcuim arsenate, one gallon table quality Of syrup ana one gallon of water.
 Syrup mixtures must always be un- fermented and should be applied with in 24 hours after mixing; at the rate of about one gallon to the acre ana put on with a mop so that few drops may be placed in the tips Of the plants.
 In case straight calcium arsenate dust is used for this single applica- = ton of pre-square poisoning, the dust may be shaken from bag with equal effectiveness, while weevils are feed ing in tn tips of the plants. The bag treatment is, however, not effective on larger, ruiting cotton.
 O o O = For Poisoning Fruiting Cotton.
 For treating cotton generally and especially on soils capable of pro- ducing one-third bale or more per acre, normally, the calcium arsenate dusting is most reliable and profit able, and is strongly recommended in preference to late season applications of any syrup mixture or other liquid poisons yet tested.
 Dusting fruiting cotton should be- gin when 10 per cent of the squares show weevil puncture and at least three applications of five pounds per acre should be given with proper ma chinery and at four and five day intervals. Thereafter, calcium arsen-
