New MU app helps identify herbicide injury

MU Extension introduced a new mobile app to identify herbicide injury at its annual Pest Management Field Day on July 10, 2018.  MU Extension weed specialist Mandy Bish says Herbicide Injury ID lets users send photos of injured plants to MU Extension for preliminary diagnosis and feedback.  Users can also scroll through a library of more than 200 photos to look for similar types of damage.  When the app launches, users can choose from four options:  diagnose injury, search by herbicide, view sites of action or send photos and detailed description to MU for diagnosis.  

Bish says the app is not limited to corn and soybeans.  I includes photos of some ornamentals, cucurbits, tomatoes and trees.  It will continue to be expanded.

Download the Herbicide Injury ID app from the Apple App Store or Google Play on any mobile device.

Soil testing

Soil tests save time and money.  Soil testing is the best guide to the wise and efficient use of fertilizer and soil amendments, said Manjula Nathan, director of the University of Missouri Extension Soil Testing and Plant Diagnostic Services.  Whether you grow acres of row crops or have a vegetable patch in the backyard, a soil test will provide you with an analysis of nutrients and a set of recommendations for any improvements.

We frequently get questions from customers like, 'I apply fertilizer every year. How come my plants are not doing well?'" Nathan said.

"Most of the time the problem is they never have done a soil test, but have been guessing on fertilizer requirements," she said. "They do not realize that by guessing they are wasting money by over- or under application, and the excess fertilizer can end up in streams, ponds and underground water, polluting the environment."

Soil testing provides analysis of pH, phosphorus, potassium, calcium, magnesium, organic matter percent, neutralizable acidity, cation exchange capacity and nutrient requirements.  For information on test results, see MU publication G9112, Interpreting Missouri Soil Test Reports. Regional specialists also can assist you with additional information and recommendations. Soil testing can be done through the extension office. See Services for details.
