Weed scientist Dr. Pam Hutchinson talks about some of the challenges and problems that she encounters while studying potatoes and their interaction with certain weeds. David Sparks AG Information. I look at just the biology of weeds, so like hairy nightshade is a real troublesome weed in potatoes. So I've looked at how the competition from Hairy Nightshade affects potatoes over certain period of time. It's like music. You're looking at things over time. We found out Hairy Nightshade, even though it's not a very big weed, it still can compete with potatoes and you lose yield if you have that weed there, right? When the potatoes emerge to about four weeks later where the foliage kind of closes over and you have more complete shade, I do interesting things like that and I have been working on a project where we look at different things at time, at the end of the season when we want to kill the potato vines so that we can get in and harvest. So I'm looking at the effect of how fast we kill the vines and the effect on whether or not the tubers bruise more easily or not. If you can get a fast kill, and even if you're late out in the field, you can still get your variety that won't bruise as much as it would if you had a slower kill when it's pretty late in the season evolved into more things than we control because some of the herbicides are used for vine kill. Speaker1: Dr. Hutchinson was talking about hairy nightshade, a weed that can harbor diseases and pests that affect closely related crops such as tomatoes, potatoes and peppers.
