Look out for tomato leaf spots this year

The most commonly grown crop in central Indiana gardens is the tomato. They do well in our climate; however, as any experienced grower knows, they are also susceptible to several diseases.

About this time of year two common fungal leaf-spot diseases often appear on tomato plants. Septoria leaf spot and early blight are both characterized by brown spots on the leaves.

Septoria leaf spot usually appears earlier in the season than early blight and produces small dark spots. Spots made by early blight are much larger and often have a distorted "target" pattern of concentric circles. Heavily infected leaves eventually turn yellow and drop. Older leaves are more susceptible than younger ones, so these diseases often start at the bottom of the plant and work up.

This is the type of year where both of these diseases can become prevalent. The reason is that each of the pathogens responsible survive in the soil and old plant material. When we experience vigorous rainfall, such as we have had several times over the past few weeks, soil particles carrying the fungus are splashed onto the lower leaves of the plants. The warm, humid weather we've been having is also very good for the development of these diseases.

These diseases can spread rapidly, so it's important to scout for symptoms. If you find evidence of them, fungicides can be effective in preventing their spread. Be sure to apply fungicide to both upper and lower leaf surfaces, and reapply if rainfall removes it.

  • Teach children to contribute as well as receive I receive a lot of emails and phone calls from parents facing difficulty in their parenting. Often parents ask, “What do I need to give my child? What do I need to do for my child?” While there are many moments we as parents need to give or do something, sometimes the answer lies in expecting from our children.

  • Exercise helps body resist injury I hurt myself last week. It’s a good one too. Low back, below the belt, all the way across. Hurt. When I get hurt, I am instantly grateful for the strength training and body care I do every week and the knowledge I’ve gain from moving my body regularly.

  • A bee, or not to be It’s weird that while working in my garden I am always looking for insect damage as a positive sign. I spotted lots of torn leaves on my Dutchman’s Pipevine and was pleased. The vine is a larval food source — caterpillar food — for the Pipevine Swallowtail, one of Indiana’s many swallowtail butterflies.

  • Vacation workout can be simple, convenient It’s vacation time, so many of my customers are requesting workouts they can do while on vacation to stay in shape. The tricky part is 1.) knowing what kind of equipment they will have, and 2.) if it’s too complicated, they won’t do it. So I like to keep it as simple as possible to minimize both of those barriers.
