Emphasizes the need to plant early maturing varieties to insure an early- 

 crop. Seven early varieties are recommended.

The authors discuss plant characteristics, such as proliferation, early 

 bearing, determinate growth, hairy stalks and stems, abundance of secretion from 

 nectaries, pendent bolls, involucral bracts grown together at base, and thick- 

 walled bolls and tendency to retain infested fruit, all of which affect weevils 

 adversely.

 conditions in Georgia. Ga. State Bd. Ent. B. 46:34. Jan. Atlanta. 



Much information useful to cotton growers as to varieties of cotton which are 

 most resistant to the boll weevil and wilt disease. Tables show results of dif- 

 ferent varieties. 



The weevils begin to emerge early in the spring and feed first on the buds of 

 the cotton and later on the squares. The buds that become blackened after the 

 attack should be picked off, as well as the squares that become yellow, while those 

 that fall to the ground should be collected and burned once a week until about the 

 middle of July. As a rule, until August the boll weevil is not sufficiently numerous 

 in the field to destroy all the squares that appear. In the absence of sufficient 

 squares, the matured bolls are attacked; hence, the necessity for selecting a 

 variety that will continue to fruit until late in the season.

Ent. B. 52, 38 p., 1 fig. Jan. Atlanta. 



Describes in detail the results of 9 tests made with varieties of cotton 

 exhibiting earliness and, therefore, adaptation to escape attacks of the cotton 

 boll weevil and resistance to wilt disease and anthracnose.

C. 29, 9 p. Jan. Atlanta. 



The results of a series of cotton variety tests are summarized and from 

 them are drawn recommendations as to the varieties of cotton that can be most 

 successfully grown under present boll weevil and disease conditions in Georgia. 



The ideal cotton plant to grow when the cotton weevil is present should begin 

 fruiting close to the ground, early in the season, and have long fruiting branches, 

 at the base, that continue to grow throughout the season. Under boll weevil 

 conditions the more cotton that is produced on the lower half of the plant, the 

 larger will be the yield per acre. 



A. grandis is now present in the greater part of Georgia, and it is important 

 to grow a variety of cotton adapted to the soil and climate and to keep the best 

 improved seed of that variety. If an individual does not improve his own cotton- 

 seed by careful selection, it will pay him to buy improved seed from someone 

 who does.
