In the past I have grown sweet corn but the cobs get attacked by an orange beetle with black spots, (pumpkin beetle)?
They attack through the silks.
How do I deter these beetles before they start please?
Hi Wayne,
You could try planting your corn seeds in pots and putting them in a greenhouse or a shade clothed area. That's how I'm growing mine this year. Hope this helps.
A simple way would be to place a small cover/bag/sock/plastic bag with a few small holes (???) over them to stop the beetle getting in there. You can go on the internet and find fruit bags from China. Cost about 20c each - have to wait for about 2-3 weeks to receive them.
