[Terminator] Why doesn't skynet use chemical and or biological warfare against humans?

I haven't watched the Terminator:Genesis , if they do use that against them then I'll have to watch it. If they didn't use it then why don't they? Why don't they engineer a superbug that resist all medications and kill all humans. Why kill them with machine guns and laser guns when you can just sprinkle them with virus and whatnot?

Those methods work less effectively when the population is scattered and scarce. You need humans moving between places to effectively transmit a disease between populations and the remaining humans may not be traveling between clusters enough to make it worth while. Any survivors would have immunity as well. It’d be much easier to just contaminate/destroy water sources or use radiation than biological agents.
