No sir, it's too early to spray. Next step is to get the lyme out after the test results. It takes a very long time to break down. After you see the ammount needed. Have the guy apply it as soon as he can get in the area. It is a very nominal fee to get the local co-op out and do it when purchased by the ton. From this point it can be left until mid April.
2-3 weeks before planting time it's time to plow and disc. Then at the time of planting fertilze disc and seed while cultipacking or dragging the field to ensure a good seed bed with ample soil contact.
Personally I don't spray, but if you wish, the leaves on what you want to kill need to be green. That would set planting time back another 3 weeks or so and your tonnage offered to the deer will suffer. I do not know of a herbicide that kills seed. So you still have to disc to kill the new germination. Herbicide has become common with the new farm practices of no till by drilling seed. But if you do a turn and disc practice it is waisting a whole lot of money and nutrients that could have been put back into the soil from the rotting germinated sprouts and live roots you turn under and chopped up. The weeds and grass have so many different times of the year when they are active it is impossible to kill them all with herbicide unless sprayed every month. When they are in their dormant stage most will not be killed. Plowwing them under then chopping up the roots with the disk will kill the majority of plants. I do run no till on my row crops. But you depend on killing everything that is active. Then getting the crop up to shade and choke out any weeds that may germinate afterwords. There are still weeds they just can't compete with the main crop so they are stunted and draw fewwer nutrients from the soil than a full grown weed.
