The July 21 treatments were either: a 'spTay of KarsH by itself
if Simazine had been used in the-June 21 treatment •. or' a combination of
KarsH plus Slmazine if Simazine had notbeeaiUaed earlier.. Karsil was
the-only herbicide ' available ·t.oua'that would kill annual gras.es 1-1 1/2"
tall and also kill lar.gel' broad-leaved' weeds without 'appreciable injury
to strawberry plants. Karsil, however. could be expect.d to give only
temporary control of grasses so it was necessary. to add Stmazlne for
longer· residual weed. control, if $lmazine ·.d not been u.ed in the June
21 treatments. All' previously treated plots. except the Ca.oren and
the Dacthal plua. Slma.ineplots received: an appt'ication :0£ either lCarsil
or Karsil plus Stmazine on July 21.
Between August 30,. and September 8. 1960 all gruses and
broad-leaved weeds were pulled and wei8hed' "parat.ly for each plo.t:.
The average weight of grasses', and broad-leaved. weeds for each,treatment
is given in Table 2. In' the foltow:iD.g di'$cus.tota on weeds the hoedcheck
plots will not be included since weeds were removed periodically
throughout the seasOn. These hoed-cheek plot.- are of value fo~ compariog
