rotary cultivator vs sweep cultivator

[HDLABS]

Anyone got an opinion on the rotarty cultivator for corn vs a sweep cultivator? Just trying to decide what to get? If i plant rr corn do i still need to cultivate?

don't cultivate...if you apply pre-emerge the cultivating will break the seal on it also

thanks...what if i don't do preemergence....what if i plant, cultivate and then spray round up? or do i just need to plant and then round up?
what about sunflowers that aren't rr? I'm just playing tryiing to grow some corn for deer but have been over run with weeds in the past.

Now that seed companies have developed RR corn in so many varieties, my Lillison cultivator is collecting rust. It is a great machine and with a great operator it'll clean up a field. I will only use it now and again to get rid of volunteer RR or LL corn, if needed.

Purchase some RR corn, plant it, spray it, lay-by N, spray again after the field weeds up then flood the field.

This will save you time and dollars in the long run.
