1980 research Paul? A little dated don't you think?

Moving on my point is simple. For two years our Midwest fields have been
water logged in the spring when Roundup has been applied. Rains have been
several times a week and usually an inch and up in a short period of time. 
No
studies have been done under these conditions. Some fields have had round up
done several times.

The leaching of round up explains two years in a row of clover not coming
up in run off areas from round up fields. Nothing else does.

This is the lowest rate ( many use higher amounts and repeated use is common
from rain. )and a gallon of concentrate makes how much spray Paul?

reporting from the rain soaked Midwest watching the creeks and rivers flood.
14 inches of rain north of me last week in places. The rain is supposed to
slow over the next week . Supers on with some nectar but expect much bee
activity to start then. Comb honey supers ready.
