Simple one. I removed my sunflowers from the pot today as they were showing a rust leaf problem and not doing great. They did flower and got pretty tall but then just went sick and I tried the nutrition etc. I am in the Sydney region Australia.
So when removing them from the pot I found some of the grubs in the pictures below, sorry a little out of focus but they are about 0.75cm long and getting a shot on a cell phone with macro mode is like finding a honest politician.
There were several of them in the pot. Now I know not all insects and other critters are nasty to my plants but should I ready the flame throwers or just ignore them?
From my research this afternoon they appear to be curl grubs according to this page
Since I am concerned that they have spread to other pots(Veggies, herbs etc) what type of pesticide could I use to rid myself of them while keeping the safe for consumption?
