Abstract

A field and greenhouse study was conducted to determine the relative effectiveness of preemergence herbicides applied at low volume (9.35 to 37.4 L/ha) and conventional volume (187 L/ha). In the field study 11 preemergence herbicides were applied to plots seeded with seven weed species. Five herbicides were used in the greenhouse study each applied at five rates and two volumes. Both field and greenhouse results indicated that water soluble materials and emulsifiable concentrates which need not be incorporated can be applied at low volume with results comparable to conventional volume application. Field results suggested wettable powders can be applied low volume with success; however, greenhouse results indicated that with present equipment and technique wettable powders are not well suited for low volume application. Incorporated materials were included only in the field study and gave irregular results.
