Help settle a spraying dispute please

[Brett Helmkamp]

My neighbor and I have a friendly dispute regarding spraying.

He came over to borrow my sprayer the other day becuase he has a lot of clover in his yard. I told him that now it is frosting it is too late. The legumes are done for the year now and spraying is pointless. He says that fall is the best time to spray so it is still ok. We live in northeast IN and have had a couple of frosts now.

Who is correct on this matter? Thanks

I have read on containers like Roundup for example, that you apply the product to "actively growing bla bla" with some stage of growth specified, like young, immature plants and may include time of day and an ingestion period before rain is expected to give the plant time to absorb it.

So, based on that I will go with his response.

You are correct. Fall might be a good time for seeding and fertilizing, but any kind of weed control is pretty much a moot point because the weeds are already either dead or dormant.

If he is spraying 2,4-d I would still spray the grass with it. The broadleaf weeds are storing nutrients right now and expanding their root system. I would spray that now.

They always told me the best time to spray field bindweed is in the fall,before or imediatly after frost.As stated,after frost is too late for most things.

I've never tried to kill clover, so don't know the answer to your exact question.

Some broadleaf weeds - like Canadian Thistle - use this fall period to feed their roots, and after the first light frost is the _best_ time to kill those weeds. they go into 'hyper squirrel mode' and try to lock away as many nutrients as possible in their big root systems. If you spray them then, thay also put the most chemical into the root system as well, and you get the best kill by far.

Dandy lions are the same way.

Clover I just don'r know if it acts this way or not, but I would think it might?

But anyhow, for _some_ weeds fall, even after a light frost, can be the best time to spray.

Fall is the best time to spray broadleaf weeds.

O.K. I need some help along the same lines.. Have a filed that I want to be real good clover.
Has some weeds and lots of narrow leaf grass in it now. Is there anything that will kill the weeds and leave my clover?
 

[Fergienewbee]

You want 2-4-DB, labeled to not kill clover. 2-4-D will kill it.

OK, I am not too big to admit when I am wrong. I will let him know about it.

Thanks guys for the input. Never too old to learn something new.

Depends if it's been a hard freeze or just a light frost too. Up here in our part of Wisconsin, we still haven't had that really hard killing freeze yet but we have been touched by a light frost. Alfalfa and clover is still growing some, albeit slow.
