1907 - Flynn, C. W., Jr. Experiments in the late planting of cotton to avoid boll weevil 

 damage during 1906. La. Agr. Expt. Sta. B. 92:8. 



Experiments were conducted to determine whether general late planting in 

 regions infested by the boll weevil could reduce the damage done by that insect. 



One experiment was conducted in Vernon Parish in a field of 2^ acres sur- 

 rounded by forest and about 2.5 miles from any other cotton field being planted on 

 June 6. On June 14, when the cotton was up to a stand, no boll weevils were ob- 

 served, but on July 21, when the field had just commenced to square, 10.4% of the 

 squares were found infested, and on August 15, 63.6%. An inspection of some of 

 the nearest fields on July 21 showed that from 20.4% to 67.8% of the squares were 

 infested with the boll weevil, and a later inspection showed 92.5% to 99.2% of the 

 bolls infested. The experiment field, which in previous seasons produced 1,200 

 lbs. of seed cotton per acre without fertilizer, in 1906 with late planting, produced 

 only 266 lbs, although well fertilized and well cultivated. 



A second experiment at Merryville gave similar results, and the conclusion 

 is drawn that late planting will not serve to solve the boll weevil problem.

A number of cultural experiments were carried out in different sections of 

 the cotton belt, during which it appeared that Triumph cotton is the best variety 

 for use in sections infested with boll weevil. Northern-grown seed, in order to 

 retain its early maturing qualities, must be renewed from its northern sources 

 at least every other year. The results obtained from these experiments confirm 

 previous work along this line, and the author, therefore, recommends thorough 

 preparation of the soil, early planting, the use of early varieties of cotton, abun- 

 dant fertilizers, thorough cultivation of the crop, and destruction of cotton plants 

 in the fall.

A brief and concise statement of the boll weevil situation. Methods of control 

 are discussed. These include the fall destruction of cotton stalks and other cul- 

 tural methods.

A revision of Bur. Ent. C. No. 56, with additional data obtained from recent 

 experiments. Following an introductory statement, results of a large practical 

 test of the efficiency of the fall destruction of cotton stalks are presented. Reasons 

 for the destruction of stalks in the fall are given; also a brief summary of the 

 data obtained from a large series of hibernation experiments upon which these 

 reasons are based.

Pest Comn. C. 15, p. 4. 



In average seasons when it is possible to produce an early crop of cotton the 

 author does not recommend the additional expense necessary in picking up and 

 destroying infested squares, it was impossible to secure an early crop during the 

 present season and the author, therefore, suggested as a means of preventing the 

 undue ravages of the boll weevil that fallen squares either be destroyed or con- 

 fined in wire-cloth cages to allow the parasitic insects to escape. 



1908 - Hinds, W. E. The first and last essential step in combating the boll weevil. J. 



Econ. Ent. 1(4) :233-243. 



The destruction of stalks by some effective method as early as possible be- 

 fore the normal time for weevils to enter hibernation constitutes the most effec- 

 tive method now known of reducing the severity of the weevil attack upon the fol- 

 lowing crop. The author considers that this procedure deserves general recognition 

 and adaption as the last step in the treatment of each season's crop and also as 

 the first step in the production of a crop with the minimum weevil injury during 

 the following season.
