Our corn has grown well but on opening it to check there were caterpillars eating it. What is the best way to control these?

If they don't eat much just cut the damaged section off. That is what I do. Caused by the heliothis moth. Look on the internet for a spray.

Plant 2-3-4 rows about 80-90cm between rows. When plants are about 40-50cm high run some fertiliser down each side of the plant and then hill the soil up around the plants. Makes the plant more stable in the ground.

I’ve always though corn was super hardy. My plants are about 3 weeks old, decent size and some little green caterpillars (about 1cm long) smashing it. Please help, what can I do? Natural solution?

Hi, we use a mix of 1 tablespoon molasses to 1 litre water on caterpillars in corn, swamp lilies, and new cycad leaves. Molasses is available in 2 litre containers from produce stores. Good luck.

Go to iView (ABC TV) on the internet and find Landline from yesterday Sunday 5/04/20 and watch the show. There is a story about the army worm (I think) that has just arrived in Northern Australia in particular Qld that is hammering sweet corn/maize.
