Faunsdale, AL | Get it out and get it dry or sold. The Aspergillus mold grew in the field and most likely is still growing and producing toxin. The toxin that is there isn't going to go away, but if you can blow a lot of the tip kernels and damaged ones out the back of the combine, it might help some.
In the bin, a damaged kernel is more easily parasitized by the mold than an intact one. Fines are the ultimate damaged kernel, lots of exposed surfaces for the mold to grow on, plus they interfere with drying in a bin. So if you have lots of fines, and there is enough moisture at the temperature your grain is, you may have more mold growth and toxin production. If there's not enough moisture there, no more mold growth, no matter what fines you have.
I would guess that most of the recommendations about moisture and temperature for storage are for undamaged grain, not fines. \
There is a product called Aflagard that can be applied at about the time the ear emerges that will infect the corn with a competetive strain of Aspergillus that doesn't produce aflatoxin. Also for peanuts I believe. | |

a-toxin better or worse if left to field dry?
