Large brown patches in Queensland Blue lawn during cooler months.
The lawn was in pretty good condition when we moved in but over the years, I've got it in very good shape and it is healthy and minimal weeds. It gets lawn grub infestation every year in summer but I treat with appropriate grub killer and I generally give it 2 to 3 hits with fertiliser over spring-autumn period. This year is the worst it has been. There must still be grubs in the lawn as there are still plenty of birds around eating grubs from the lawn but I've treated it several times this year. I've read about "dollar spot" but I'm in Queensland and "dollar spot" seems to be more for down south. It's also much larger the the dollar coin. We have had more than normal rain in Brisbane this summer so it is not from lack of water.
For controlling the larvae, it is best to spray in mid-spring with "Yates Grub Kill & Protect for Lawns" against a large range of common lawn pests including curl grubs, various beetle larvae, caterpillars and provides up to 6 months protection for your lawn.
