Thanks everyone for your advice.

Firstly Simazine is readilly available and we use it on TT Canola, Chickpeas, Vetch etc.

I would be looking to use it as a post plant pre em with Atrazine and Metolachlor on corn.

Matt, unfortunatley, we can't get Nicosulfuron, Foramsulfuron or the like. Mesatrione(Callisto) I think originated in Australia but I don't think it is available to Australians! Would Cyanazine (Bladex) be better than Simazine? or safer? I was looking at using 2kg/ha (2lb/ac) of Simazine ( loam soil).

Martin, I will be looking to plant chickpeas after the Corn, or if it is too wet (like this year) it will go back to corn. Our average ranfall for spring/summer is 7".

Cheers

Jim
