not yet seen the statement , so I do not knovr of its details or just 

 what is covered. Following the meeting at Memphis, an agreement vjas 

 worked out with the U. S. Department of Agriculture with the result 

 that a field station and laboratory are to be established in Tennessee. 

 The laboratory will be at Jackson, and the field work will probably be 

 conducted in Lake County, or wherever we find suitable infested areas 

 available for our use. The laboratory building is about comnleted and 

 will soon be in operation. 



Since the discoverj'' of the soybean cyst nematode in Tennessee, we have 

 been doing some work in a fumigation experiment. We have a total of 

 six chemicals under test. They are being applied at four rates each 

 and in both row and broadcast applications. The rates are the normal 

 recommended rates, one-half normal, one and one-half normal, and double 

 the normal rates. These are applied in plots of five rows, thirty feet 

 long. The plots have only been planted for about one month, so we have 

 no results to report as yet. 



We have also been checking to see if there are other hosts for the 

 nematode in our area. We have planted many cultivated crop plants and 

 as many wild or weed plants as we could obtain seed. VJe have found 

 that white lupin is readily attacked, producing many cysts when grown 

 in pots containing soil from infested areas. We have found cysts be- 

 ing produced on a common weed which is not a member of the legume 

 family. As this may be a first report of a host outside of this plant 

 family, you may be sure we are having this checked very carefully. 

 A compilation of the host range testing work will soon be printed in 

 the Plant Disease iteporter. 



Discussion 



Q. Do you know what the quarantine regulations are that went into 

 effect yesterday? 



A. No, not exactly, as I only have a copy of what is in the register. 

 I have not as yet seen the quarantine statement. 



Q. Is the quarantine a state by state one? 



A. No, at the present time the quarantine covers North Carolina, 



Tennessee, and Missouri, Hearings are to be held July 2h on the 

 question of including Arkansas and Texas. I think the regulations 

 will be uniform from state to state. 



Q. How effective did you find Telon to be relative to D-D? 



A, Telon was not as effective as D-D, but you know things can go 



wrong in experimental work of this sort. The applicator device 

 can become stopped up, or some other incident o C that kind can happen. 

 ['h are going to repeat the tost again this year to know for sure that
