Hi everyone, we need all the help we can get, Rutherglen Bugs have invaded our Potato Crop of about 1/2 acre, we have been growing organic Spuds for the last 4 years and never had a problem like that, primarily the weak plants are affected, I had them attacking my kohlrabi,cabbages and radish, some also on peas but not as many….(vegi garden is about 500 meters away from the potato patch)
I have used pyrethrum, pest oil separate and combined with soapflakes and a little borax to NO AVAIL !!!
We did call the Bugs for Bugs mob to see if there is a predator that we can use against the blighters there is nothing out there except insecticide that we are definitely not going to use…..
We don’t have any chooks or other birds that could help to keep the bad insects at bay, that might be a start?
Any idea what to do?
Thank you for reading this!!
have you tried hosing them off ?
I’ve been using soapy water
I haven’t been checking this forum often enough. I won’t use pyrethrum, although ‘organic’ it is dreadful stuff and many of the synthetic poisons are probably less harmful for you.
The rain we have had has caused the Rutherglen bugs to build up to incredible numbers. I have been experiencing a lot of trouble with them this year.
Rutherglen bugs appear to be strongly attracted to light, so for something small like a half acre a bug zapper will make a noticeable difference to their numbers. If you put some kind of container under the zapper you can collect the partly zapped injured bugs and feed them to poultry (assuming the ants don’t carry them away first).
