Tomato diseases and their treatment, photos

By carefully monitoring tomato cultivation from the moment the seeds are planted, researching tomato diseases and their treatments in advance, and carefully examining photos (as many mineral deficiency diseases are similar), problems can be avoided. This is especially true for dangerous diseases like late blight, which causes significant crop losses.

Tomato diseases - prevention

In the fall, dig up problem areas to ensure the soil freezes thoroughly, treat them with potassium permanganate in the spring, and apply ash when planting seedlings—all these measures can reduce the incidence of disease by up to 50 percent. Next, just a week after planting the seedlings, treat them with copper sulfate for even greater protection. To do this, add 1 g of copper sulfate to 4 liters of water and spray it on the leaves. Then, before flowering, treat with epin, which will both protect against disease and increase yield. One ml per half bucket of water is sufficient.

If all else fails and the most important tomato doctor, late blight, has begun to manifest, treat the tomatoes with copper-containing products such as Bordeaux mixture. Remove all diseased leaves and mercilessly burn them to prevent spreading the disease. A garlic and iodine infusion is also effective for this purpose. Then, spray the tomatoes several times (every 5-7 days) with the following infusion: a cup of crushed garlic, 1 g of potassium permanganate, and a couple of tablespoons of grated laundry soap. Dilute all of this in a bucket of water and spray approximately 100 g per plant.

Powdery mildew can be prevented on tomatoes using an infusion of mullein, baking soda with water and soap, colloidal sulfur, or fungicidal preparations like Topaz. Incidentally, if you had this problem last year, a solution of 80g of copper sulfate per bucket of water, thoroughly sprayed onto the soil, will help disinfect it.

Folk remedies are also effective for preventing tomato diseases. They recommend treating and sprinkling tomato seedlings with ash when planting them: pour 1 kg of ash into a bucket with warm water. Let it sit for a week, then strain. Spray the bushes and soil for three days in a row, which will help disinfect both the plants and the soil.

Experienced gardeners insist: start spraying tomatoes in June with a weak solution of potassium permanganate, then a week later do the same with a solution of boric acid (1 teaspoon per bucket), again after 5-7 days make a solution with the addition of iodine in the same proportions, and they promise that late blight will not settle in your area.

Treatment of diseases

Gray mold appears in damp weather as dark spots on the leaves and a gray coating. Simply remove the lower leaves, thereby increasing air circulation near the roots. Once sunny weather returns, the problem will subside.

Blossom-end rot is a common tomato disease caused by a calcium deficiency. It manifests itself as blackening of the tops. To prevent this, add a spoonful of ash and calcium nitrate when planting seedlings. If this is not the case, water the green fruit with the solution.

Mosaic spreads especially quickly during pricking out, replanting, staking, and pinching—that is, during care that damages leaf hairs. Control: Use treated seeds. As a preventative measure, water the seedlings several times with a weak pink solution of potassium permanganate after planting.

Fusarium wilt – leaves turn yellow, stems turn black, and bushes wilt. This is a fungus that can penetrate the bush from the soil. Prevention is crop rotation, treatment is with Trichodermin, and Previkur has proven effective.

Septoria leaf spot is especially common in humid areas and appears as white spots. Control: Remove and destroy affected leaves. For such areas, it's important to select varieties with resistance to these diseases. If septoria leaf spot appears, spray three times, 10 days apart, with a tried-and-true 1% Bordeaux mixture.

Blackleg is more common in greenhouses where seedlings are grown, especially if they are poorly ventilated. The root collar rots, and the plant dies. Treatment can be achieved by watering the plants with a furacilin solution. Use preventative measures more often, and you'll have fewer problems and worries later, as your tomato crop grows.
