about the 20th of July amd the second about the 1st of August. Samples 
of volunteer wheat collected at Hays and in southeastern Ford County 
had as high as 30 flaxseeds per culm on August 20. Full emergence 
is now taking place in this volunteer wheat. 
There has been a determined effort on the part of the farmers in 
many counties^to follow the program recommended for Hessian fly control, 
3arly harvest this year made early seedbed preparation possible, and 
there has been ample opportunity to keep down volunteer wheat and 
prepare a good seed bed. As a result, in seme counties every stubble 
field was turned tinder by the middle of July and at present it is 
difficult to find volunteer wheat. Good rains the last fev days have 
put the ground in excellent condition, so that wheat sowing-can be 
delayed until the recommended date with safety. Most of the flaxseeds 
now contain pupae of the fly and it is expected that the recent rains will 
bring out the adults within the next few days.
