$100 ?!?!?! A dropper will do me just fine, thank you.
Thanks for all your help. I'll try the dropper on one variety, the pump on the other. Of course the mystery of when the moths fly could not have ANY bearing on the outcome of my scientific experiment. with staggered planting and all...

I guess some googling could help you in that ''timing''regard, or a call to the local extension agent....Dates do vary a lot according to localities...

Synopsis:
Vegetable oil OR Mineral oil
Plain OR mixed with BT (Thuricide or Dipel are a couple of BT brand names)
Apply to emergent corn silks as spray OR drops.
1 small spray or 2 to 3 drops from medicine dropper or pipette.
Is this all correct?
Question:
1. There is mention of the need to not interfere with pollination. If one makes the application immediately as the silks first become visible from the husk, will that be an interference?
2. In theory, the various ears of a particular variety will present their silks over a period of several days. Therefore, it is necessary to make the application over a period of days? OR, can one make the application to the unopened tips and still achieve success?
3. How much does the addition of BT increase the efficacy of the oil alone? Is there a standard measure?

We always used a bug zapper near the corn patch to zap the
adult moths. The protection grid has to be big enough that the
moths can enter into the death zone and get fried... They don't
go easily, and if you have any neighbors they may not appreciate
the noise of huge moths getting turned into bio-char.
Regards,
Joseph

Already called my extention office. They politely claim it is one long season of orgy... No help there.
