Molte volte sul forum viene chiesto se l'antigerminello in caso di pioggia immediatamente succesiva all'applicazione perde di efficacia. La risposta come già sappiamo è no, ma quanto può incidere ciò nella vita reale? Da uno studio sul campo è emerso che irrigando con 2,5-5mm post applicazione l'efficacia può aumentare fino al 50% rispetto al caso in cui si irrighi 3 giorni dopo.
Watering-in: Tough the label on all
PREs (especially the sprayable formulations)
clearly state that they should be
watered-in within 24 to 48 hours afer
application, this recommendation is
ofen ignored.
However, watering-in PREs immediately
after application with 0.1 to 0.2
inches of water resulted in up to 50
percent improved crabgrass control in
one of our studies on fairway-height
Kentucky bluegrass in 2011 (Figure 2).
Watering-in the PREs moves the active
ingredient to the soil, where it can
be effective and reduces loss through
volatilization and UV degradation.
