As always, catching it early would greatly enhance your chances of a successful outcome.ĭry season: In some countries, it is preferable to plant tomatoes in the dry season when there is less moisture in the air and soil. Both are very effective methods of controlling blights (both early and late). (1) Copper Sulfate (2) Serenade Fungicide treatment. Once the disease starts, fungicides can be used to help control it. I have successfully used two different fungicides to control early blight. Examine plants often for any signs or changes. Because once it has been established, it can be difficult to control. The best way to manage diseases is to be proactive. Hosts: (Other plants that carry the disease): Tomatoes, potatoes, aubergines, peppers, hot peppers and other nightshades. Early herbaceous blight is most prevalent in plants when stressed by low fertility, heavy fruit load or nematode infestation. So it’s evidently worse during the rainy season. Fungus is most active in mild to warm temperatures and humid weather. Spores which land on tomato plants germinate and infect the leaves when wet. It can be carried by seeds, water, wind, insects, humans and agricultural equipment. Disease Cycle Of Early Blightįungus can survive in soil and infested plant and weed residues. Dark, dusty spores are created in concentric rings and can sometimes be seen when a light object is touched on the spot. The spots on the fruit are similar to those on the leaves – brown with dark concentric rings and often begin where the “fruit stalk” adheres to the tomato. This infection can also spread to plants that belong in the same family, like potatoes. The early blight fungus prevails in winter and usually spreads due to infected soil. The affected leaves die, thus exposing the fruits to sun scald. At the beginning stages of early blight, the surrounding leaf area turns yellow. Early blight will often spread quickly, infecting other plants, especially closest ones. You can easily check and take care of your tomato plants. As the disease progresses, the fungus may infect the stems, blooms and even fruit. Leaf spots usually appear on the oldest, bottom-most leaves first and progress up the plant. Brown circular spots are often surrounded by a yellow area. Early blight in tomatoes, first becomes evident on the laves of plants. It may sometimes, although rarely, affect seedlings causing damping-off in the seedbed. The disease known as Early Blight or Target Spot (because of the concentric circles within the spot) is one of the most common and harmful diseases that affects tomatoes. Symptoms Of Early Blight In Tomato Plants. But choosing varieties with good to excellent disease resistance can also help us in our battle of early blight in tomatoes. The success of our gardens depends highly on our level of commitment to early detection and treatment. Some diseases can also occur due to poorly processed seeds and other factors. Generally, the most common diseases and problems occur due to extensive and prolonged dampness coupled with humidity. But tomatoes are usually at high risk of infestation by pests and other harmful diseases. Spraying every two weeks is a good idea, but if you have an outbreak of blight you may want to spray a couple of days in a row.Growing fresh, garden ripened tomatoes, can be a satisfying, rewarding and relaxing hobby for any vegetable gardener. Let the peroxide solution dry before watering.Once you’ve determined the best mixture, be sure to spray all sides of the leaves, stems, and fruit.Too much hydrogen peroxide can burn the plant so starting with a lower concentration is recommended. Some tomato plants might need less hydrogen peroxide and some might require a higher dose. Wait 24 hours and check your plants again.
