Liquid Sprays. — Paris Green may be applied as a spray in water at 

 the rate of one pound to 50 or 75 gallons of water with good effect in 

 checking the Boll-worm, but this process is slower and more tedious 

 and does not commend itself to the consideration of the cotton farmer 

 in the middle of our average August day. Professor Quaintance 

 found, however, a net gain of $6.99 per acre as result of three spray- 

 ings. Five to six acres per day could be treated with a barrel outfit 

 by using a team and wagon and two men. But the cost of the out- 

 fit and the few occasions on which it would be used on the general 

 cotton plantation, lead us to recommend the planter not to depend 

 on the spraying process. We believe the dusting process to be gen- 

 erally more practical and satisfactory. 



A Word About Dusting Cotton. — We have gone into some detail 

 here to describe and illustrate the methods of dusting cotton. We 

 give this discussion in connection with the Boll-worm because at 

 present it is the cotton pest most likely to require this treatment, 

 but it must be remembered that the same method is effective against 

 practically all insects which devour the foliage, squares, etc., the 

 exact result depending largely on the care and thoroughness with 

 which the work is done. We well know that with a large field of cot- 

 ton a rapid method of treatment is the only practical one, even if it 

 is not absolutely thorough. Every grower should be familiar with the 

 methods and materials used in this dusting process, so that he can put 

 it into operation without delay at any time that an emergency arises. 

 That it can be used with decided profit in bad outbreaks of Boll-worm 

 and Cotton Worm is absolutely proven, and there is reason to believe 

 that it will be of some benefit against the New Cotton Beetle and 

 against the Cowpea-pod Weevil. It will not be effectual against the 

 Leaf-louse, and its effect on the Rust-mite will be only very slight 

 if indeed there is any effect whatever.

THE COTTON BOLL-WEEVIL. (Anthonomus grandis.) 

 Order Coleoptera. Family Citrculionidce. 



Notice. — The Cotton Boll-weevil is not yet (June, 1908) known 

 to be in this State, despite many rumors of its appearance. This 

 account of the insect is given to instruct our farmers in advance. 



Description. — A brown or blackish weevil, less than one-fourth 

 inch in length, with snout about half as long as body, found on grow- 

 ing buds and young leaves of cotton in early season, and later attack- 

 ing squares and young bolls, causing squares to "flare" and drop and 

 bolls to be deformed. At present known in United States only in 

 Texas and Louisiana and edge of adjoining cotton-growing States. 

 The adult beetle is much like the Cowpea-pod Weevil in size and ap- 

 pearance.
