VEGETABLES 



Asparagus:

X TCA cannot be recommended (as of April 1, 1958) for use on asparagus since evidence has not been de- 

 veloped to prove it will leave no residue or/and tolerances have not been set under Public Law 518. 



2 DNBP cannot be recommended (as of April 1, 1958) for use on asparagus since evidence has not been 

 developed to prove it will leave no residue or/and tolerances have not been set under Public Law 518.
