The only thing that has worked for me is to apply 7 powder on the silk. Not hardly feasible for a large crop, but I only grow a small amount. There must be some way to do it, since it’s grown commercially. I have a friend that leases out 15-20 acres for sweet corn. I’ll ask him if he knows how they keep the worms out of it.

How long after the silks emerge do you spray it with liq sevin, and at what concentration? Straight 5% or diluted?
Safe?

I've heard some swear by Canola oil on the silks?????? Worms need to eat too. :lol2: They don't seem to bother my Tender Treat as much as other varieties I plant.
Now the grasshoppers are a different matter entirely. One year, I just knew judgement day had past and I was in he!!

I haven't tried it but I' too have read some have fair luck pullin the shuck back a little and putting a couple drops of food grade mineral oil on the end of the ear, then gently putting the shuck back in place. Others said they had poor luck and saw no difference when they tried it. (you can get food grade mineral oil at a drugstore)
It don't bother me much cutting the ends off, but wife complains each year that our corn has worms and cuttoff ears and all the corn she sees in the stores are perfect ears.

I mix the liquid 7 VERY weak. I start spraying as soon as I see activity. And respray if there has been rain in a week.
I don't think it hurts pollination either to have me walking thru the rows and shaking things up a bit :)
Safe????- I am still alive.

I tried the oil one year- and had a terrible crop. It probably had nothing to do with the oil, but in my mind I cannot separate the two of them.

Bt applied right when the silk starts and again when it starts to brown has kept our corn really clean for a few years now and you could drink the stuff without any side affects other than gaging from the taste.

Bt is short for something I can't spell basillus thuregensis is about as close as I'll get without looking it up. It's a bacteria that gets in the gut of moth and butterfly larvae and kills them. It isn't toxic to anything except certain moth and butterfly larvae. You can eat the crop ten minutes after you spray it. It also does a number on the caterpillars that eat up broccoli and other cole crops. I think it's sold over the counter by Safer brand which is Monterey Chemical but you can buy it in bulk under generic names at most ag chemical supply places. Just spray it on the silk like you would any pesticide and you're good to go.

Or just buy BT sweet corn seed. The corn in the store is sprayed everyday for quite a few days.
