July heat has arrived in Missouri, and it’s putting garden and landscape plants at risk. Because we had such a wet spring, plants, trees and shrubs don’t have the deep roots necessary to ride out the summer heat and less rain.
Today’s guest is David Trinklein, horticulture specialist for University of Missouri Extension. He has tips for watering your plants so they can recover from our super-soggy spring.

Nitrogen fertilizer, heat and water is like ringing the dinner bell for fungi hoping to snack on your nice green lawn. If you have tall fescue, the culprit is Rhizoctonia solani, which causes brown patch. As the name implies, brown patches show up in your lawn. Many homeowners, when they see their grass turn brown, add fertilizer and water to help it green up. Big mistake, your giving the fungus exactly what it needs.
Today’s guest is Brad Fresenburg, turf specialist for University of Missouri Extension. He has information about dealing with brown patch, how to recognize it and how to treat it.

When tomatoes, peppers, melons, and eggplant develop a sunken, rotten spot on the end of the fruit it’s not caused by a disease or insect pest. It happens when the plant doesn’t get enough calcium. It’s a fairly common garden problem. Turns out there are lots of things that can happen that can deny calcium to your plants.
Today’s guest is David Trinklein, horticulture specialist for University of Missouri Extension. He discuss the causes and how to prevent it.

“Do you know the legend about cicadas? They say they are the souls of poets who cannot keep quiet because, when they were alive, they never wrote the poems they wanted to.” ~ John Berger, author (Photo by Roger Meissen)
It’s an amazing event that only occurs in North America. Periodical cicadas live underground for 13 and 17 years, and then in one mass reproduction cession the crawl out of the ground and take to the trees. They will come out in the thousands, and it can be very overwhelming because these insects will make a lot of noise for several weeks. This year the periodical cicadas will emerge in Kansas City and Cape Girardeau.
Today’s guest is Bruce Barrett, entomologist for University of Missouri Extension. He has lots of information about these fascinating insects and this amazing event.

An annual curse when cool, wet springs trigger anthracnose to flourish. It’s caused by a group of fungi that can attack trees, shrubs, flowers and just about anything green.
Today’s guests are Hank Stelzer, forestry specialist for University of Missouri Extension and Patricia Hosack, director of the MU Plant diagnostic clinic. Both discuss this disease and why it’s important to keep trees healthy so they can survive the attack of anthracnose.

“My back only bugs me when I sleep wrong. I feel my knee more than anything, the left one. It’s arthritic.” ~ Joe Montana
One of the most common knee injuries is a torn meniscus. The menisci are two C-shaped pieces of cartilage that act like a cushion between the shinbone and the thighbone.
Today, on Mizzou Spotlight on Science, host Nathan Hurst talks with a University of Missouri physical therapy professor who is working to improve knee-injury repair and to better understand arthritis.
