Grass grub and porina damage will now be evident in most areas. Grass grub damage is indicated initially by loss of clover and subsequently by patches of pasture turning yellow. At this time of year these patches become soft under foot and are prone to pugging. Porina damage will show as bare areas of pasture often with only weed plant species present. Conventional insecticide is the only control option likely to give control of either pest. By now production losses have already occurred but treatment may save the affected pastures.
