Not entirely sure what these are, have essentially turned up today, have applied sulfur 3 weeks ago and applied Mancozeb today to see if it will help but starting to think this could be a pest issue?

Hi Benjamin Ross. Please compare symptoms with Thrips effect by clicking on green link for taking control measures from Plantix library.

Dear Benjamin Ross how are you welcome to plantix community dear the above suggestions by Suresh Gollar is correct 👌👌

Look for wind damage (cold injury) infection also dear Benjamin Ross

Benjamin Ross I agree with Suresh Gollar.

Thanks, its currently summer here in Australia and we have lows of 20c and highs of 30c, im thinking thrips, will apply treatment tomorrow

Tufail Abbas I have pyrethrum on the shelf here or should i go straight for spinosad? I also have a lot of lady beetles around ive been trying to keep to assist with aphids. The lady bugs/lady beetles are roughly 30m away on some sunflowers at the moment but will likely move soon to the corn thats 20m away from these potatoes

Dear Benjamin Ross yes dear you can but if you have any sever issue you can share with us we are really happy to help you dear

Tufail Abbas thanks for that, ill try pyrethrum at a certain foliar rate and if i continue with problems will apply spinosad, just trying to keep the lady beetles around Suresh Gollar I believe you are correct, thank you

Dear Benjamin Ross let me tell you that 10 ml dettol+chilli soap+20 ml neem oil mix in 1 litre of water and spray it dear

You are always welcome and we are happy to assist you Benjamin Ross.

I hope it will help dear Benjamin Ross
