Problems with ginseng

Would like to know why a few of my 3-leafers have a 90 degree bend in the stem about three fourths the way up the stem? I also remember Brad that some kind of small fly making holes in the leaves. What can I spray to stop this and find it locally. I also scratch around a 3yr, old the was leaning over and found a small cut worm. Do you ever treat your wild simulated in the woods before or after planting for pests like this?
