Initial chemical treatments were applied and sheep were allowed to graze on the site (around 15 DSE/ha), further treatments were applied post-grazing, including a follow up application of Gramoxone on part of the initial chemical treatments...

Note that infected larvae reduce their feeding but can take over a week to actually die... Trial data in sorghum show that Helicoverpa larvae are rapidly infected with NPV within an hour of spray application - irrespective of whether applied in the morning or evening... Earlier recommendations to always apply NPV in the late afternoon or early evening are no longer current...
