SUMMARY
Post-transplanting and 'lay-by tests of Amiben, Dacthal, Eptam.,
Neburon and Solan were conducted with processing tomatoes on two soil types.
The soils, located near Moorestown, New Jersey, were Downer loamy fine sand
and Collington fine s~dy loam. The compound Zytron was included only in the
experiments on the ~owner .sand, .:
More of the herbicides applied broadcast approximately 3 weeks after
transplanting were effective in suppressing weed growth for the subsequent
l6-week period. Highly significant reductions in yield and fruit size were resulted
from Dactha'L; Neburon and Solan treatiJents on tb:l Collington loam, and
from Neburon, Solan .and Zytron,o~ the Downer. sand.
Eptam treatments on young tomato plants on the sand resulted in leaf
burn and epinasty. Similar treatments at lay-by injured the plants only
slightly. No injury was observed in either experiment on the loam soil.
Eptam wastne on).y. material tested at lay-by that controlled both
grasses and broadleaf' weeds on1(he ..two,soal types. . .
Amiben was as effective as Eptam on the Collington loam. On the
Downer sand, Amiben did not suppress growth of grasses as well as Eptam. Loss
of efficiency on the sand was attributed 1;0 low soil moisture.
