Our tobacco crop is coming along. Some fields are about 3 weeks out from first priming. Topping and suckering is underway in some parts of the county. I have seen a few hornworms and flea beetles. Neither are very heavy as of this week, just something to keep in mind when you spray sucker control.

I have seen a fair amount of weather fleck this year and target spot on the lower leaves. Target spot is responding well to quadris this year and doesn’t seem to be spreading.

I suggest delugging this year, due to disease ridden lower leaves. I will conclude this message with a quote from an email from Dr. Matthew Vann:


My final suggestion is focused on the practice of de-lugging (removing and discarding the lower leaves on each plant). We know that de-lugging has a significant impact on our yield and value parameters, although I anticipate that many will consider this practice because of a thin-bodied and (probably) disease infested crop of lugs. This is unfortunate because there actually seemed to be a slight increase in demand for good quality lugs this season. I’m not convinced that we’re going to be able to deliver those across the board. I anticipate our farmers are going to press us on de-lugging information, so let’s be ready to send what is needed. My rules of thumb are as follows and are based on field trials that were concluded in 2017:

-the removal of four leaves is reasonable, eight leaves is too many

-the addition of 10-15 lbs of N and the removal of four leaves has a higher cured leaf yield than not adding back any nitrogen and removing four leaves.

-our data indicate that de-lugging should happen around topping (-/+10 days), but I’d say that getting it done as early as possible is ideal since this crop is going to ripen fast and needs some fertilizer.
