plots which received no side dressing than from those which were side dressed. 

 This emphasizes the importance of an effective weevil control program if the 

 added benefits of fertilization are to be fully realized. 



1951 - Hamner, A. L. Cotton fruiting in relation to insect control. Assoc. South. Agr. 



Workers Proc. 48:96. 



The fruiting cycle of cotton plants grown in fertilized and unfertilized soils 

 of 7 different types was determined for a 3-year period. Neither soil types nor 

 fertilization made enough difference in the fruiting to require any change in insect 

 control recommendations. The 3-year averages for the fertilized plots of all 

 soil types show that 8.13% of the total season's flower production occurred during 

 the first week, and the bolls developing from these flowers produced 20.41% of the 

 total seed cotton. During the fifth week 9.84% of the total flowers were produced, 

 but the bolls developing from these flowers yielded only 2.23% of the total crop. 

 The 3-year average percent of the total yield set during the first 4 weeks was 

 96.5% for the fertilized plots and 94.9% for the unfertilized. Bolls developing 

 from each succeeding week's flowers were lighter than those developing from 

 the preceding week through the fourth week.

Tex. Agr. Ext. Serv. L-173. Aug. 



Emphasizes advantages of early stalk destruction in preventing carryover 

 of pink bollworms and reducing number of weevils to infest next year's crop, 

 besides being a good practice in preparing land for the next crop.

The work upon the boll weevil conducted by the Bureau of Entomology is 

 outlined and a statement is made regarding loss due to the pest in portions of 

 Mexico. Portions of an article in the Yearbook, U. S. D. A. for 1903 are trans- 

 lated. The work of the Commission is reviewed by giving quotations from some 

 of its previous publications. The work upon the mite Pediculoides ventricosus is 

 given the greatest amount of attention.
