MR. MACHOVINA: After spraying for shuck maggot with DDT do you encourage the presence of mites?

MR. BAKER: It's very possible that you might. That has happened where DDT has been used. With some of our work with chestnut weevils, mites seem to be a little more abundant where we used DDT. We have had reports of this happening in California where they used DDT on walnuts. So it is a possibility, and that's why I brought into the paper a little information on the control of mites.

Session closed at 4:15 o'clock, p.m.
