Question: "What's the difference between broadleaf [weeds] and grasses?"
"Well, grass is more like your lawn grasses. It's what we refer to as grass. The broad-leaf weeds we refer to as bindweed and dandelions and those type of broadleaf weeds."
Question: "And corn, in fact, is actually a grass."
"Corn is actually a grass, yes. Of course, 2,4-D was strictly developed for broadleaf which would take care of bindweed and any of your broadleaf weeds We sold several carloads the first year we had it. Of course, I guess the farm people had trust in us in selling what we did."
