it’s Time to Control Early Blight on Tomatoes

Visited several commercial vegetable growers in Livingston Parish with Kenny Sharpe yesterday. Starting to see early blight showing up on tomatoes at various locations and one tomato field with bacterial speck causing a significant amount of damage on the variety Applause. Warm, wet, humid weather is ideal for the development of both of these diseases and growers should be putting on preventative sprays of chlorothalonil or one of the strobilurin fungicides to keep the early blight in check.

      For commercial growers, chlorothalonil is sold as Bravo, Chloronil, Echo and a number of other generic materials. For homeowners, it is available as Ortho Garden Disease Control, Bonide Fung-onil Multi-Purpose Fungicide, Ferti-lome Broad Spectrum Liquid Fungicide, GardenTech Daconil Fungicide, and Hi-Yield Vegetable, Flower, Fruit and Ornamental Fungicide.

      The strobilurins are really only available for commercial growers. These include things like Quadris, Cabrio and Flint.
