10 BULLETIN 382, U. S. DEPARTMENT OF AGRICULTURE. 



If, after considering the foregoing points, it seems advisable to 

 practice either of these control measures, the following seem to be 

 the best methods : 



Square picking. — A time interval of about seven days between 

 square pickings seems advisable. 



The first picking should be made within a week of the time when 

 the squares start to fall in considerable numbers. 



It is not likely to prove profitable to pick squares more than four 

 or five times. 



The squares should be disposed of as soon as possible after collec- 

 tion by burning or burying. 



Weevil picking. — The most satisfactory method of weevil picking 

 now known is the bag-and-hoop. 



The first picking should be made as soon as the weevils are suffi- 

 ciently abundant to make the operation worth while. This is likely 

 to be about the time the plants start squaring or soon thereafter, 

 although in exceptional cases it is not necessary to pick until con- 

 siderably later. 



Following this the pickings should be made as frequently as possi- 

 ble — twice a week, if practicable. 



It is not likely to prove profitable to make more than four to six 

 pickings at the most. 



Of these two measures the bag-and-hoop is likely to prove the more 

 profitable under usual conditions and is really the easiest and simplest 

 method to practice.
