92 MICHAEL SHAW 



SHAW: That's a hard question to answer. I don't think it's going 

 to give you any immediate practical solutions to your problems. As I 

 said at the end of my talk, I think the genetic approach, if you want to 

 call it that, is likely to be the more practical one. But, then you 

 never know because maybe the Cronarti ton -pine system is one of these 

 ideal systems that all the biochemical plant pathologists dream about 

 where you could put your hand very easily on some specific chemical 

 substance. 



CALLAHM: I doubt it, but has anyone found one yet? 



SHAW: No. 



CALLAHAM: Thank you.
