GENTLEMEN: June 13, 1956
You've been following closely the pesticide residue studies of Dr. C.H. Van
1iddelem here at the Main Station....cooperative with Station entomologists through-
out Florida, Van's the man whose results made possible the practical interpretation
of "parts per million" tolerances into "minimum days last application to harvest,
within limits of Florida Station research"....Circular 140, pesticide guide, hand-
book, Vegegram, etc.
NOW, there's a lot of discussion as to just what will be the situation next
season on the use of systemic insecticides in vegetables. Most of you are familiar
with the "21-day interval" before harvest recently associated with systox(demeton),
We don't have an answer at this time....however, we do know that a lot of
people are greatly interested in how systox is coming out in the two-year studies
just completed.
Below are those studies compiled and summarized by Dr. Van Middelem, offered at
this early date to assist in formulation of appropriate decisions one way or the
other well in advance of the coming Fall season. Work is continuing to supplement
this information.
