Abstract
Trial 87KA51
The decision of when to spray is one of the major difficulties encountered when spraytopping grassy pasture for seed set control. Previous work has shown the general herbicide application timing window for the major grasses, but within this window, the amount of seed set control achieved can still be poor. Obviously timing within this window needs to be more rigorously defined. The fundamental question we need to answer is; when do the target grasses begin to produce viable seed in relation to their phenological development and in relation to other grass species? If we know this, then herbicide application before this time should greatly reduce seed set. A series of three experiments was designed to answer this question in 1987
