Mix all the ingredients together and spray the solution on the affected tomato or potato plants.Īccording to Jeff, this is going to create a solution that should prevent the fungus spores from being able to survive on the leaves or on the stems of the plants by increasing the pH level. If you don’t have one already, you can buy one from Amazon for a few dollars. I found a supposed organic remedy for early blight on Jeff Bernhard’s YouTube channel.Įven though I haven’t tested yet, I’m going to list the ingredients here. Remove the affected leaves (you can also remove any leaves that are very close or hanging on the soil) and throw them away or burn them once they dry out.ĭo not use those for your compost ( here’s my composting guide) since you risk contaminating your next generation of tomatoes or potatoes when you use the compost. You need to closely watch for the first signs of early blight, which are the appearance of brown dark spots on the leaves at the bottom of the tomato plant. Here are my top 5 most effective fungicides for tomatoes. Since the disease is caused by a fungus, a fungicide is one of the most efficient solutions. Once you’ve seen the first signs of early blight affecting your plants, one of the best solutions is to apply a fungicide treatment. Utilize fungicide at the first signs of disease While you can’t do many things to save your tomatoes once they were affected by late blight, there are a few things you can do to treat early blight. By Scot Nelson from Honolulu, Hawaii, USA (tomato_late_blight_fruit_damage), via Wikimedia CommonsMost of the time the tomato fruits affected by late blight get a bad smell and become inedible. The infections with late blight usually produce larger dark brown lesions (look like rot) on a random area of the tomato fruit and can rapidly extend to the whole surface of the fruit, destroying it completely. Plant diseases don’t affect people and the tomato fruits that only present an initial stage of the disease will only present a tiny black spot at the stem that can easily be removed. If the tomato fruit managed to reach its maturity and was only affected in a small manner, you can cut off the affected part and consume the rest. More exactly, the tomato fruit will start to turn black at the lower main stem (the green tail that holds the tomato fruit attached to the plant).Įventually, the sick tomato fruit will fall on the ground. Later on, there will appear lesions on the fruit. In the initial stages, early blight will cause dark brown (or black) spots on the leaves of the plants (starting from the leaves at the bottom of the plants).Īfter some time, the affected leaves will turn yellow and either dry up or fall off the plant. When a tomato is affected by late blight, the entire plant along with its fruits can be destroyed in only a few days from the first symptoms. The evolution of late blight is much quicker than the one of early blight. It’s pretty easy to identify if your plants have been affected by early or late blight. The late blight is caused by Phytophthora infestans, a microorganism which prefer moist and cool environments.
