Applying the agricultural cycle<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Wait at least two years before planting in the same location again, as spores in the soil and any partially decomposed plants can persist for a year.<\/p>\n\n\n\n<p>This is true even if you don&#039;t see any symptoms of early blight, as the pathogen can begin to accumulate without your knowledge.<\/p>\n\n\n\n<p>This also applies to any crops in the Solanaceae family, such as eggplant, and potatoes which can also be infected by the fungus.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_%D8%AA%D8%B7%D9%87%D9%8A%D8%B1_%D8%A7%D9%84%D8%AD%D9%82%D9%84_%D9%85%D9%86_%D8%A3%D8%B9%D8%B4%D8%A7%D8%A8_%D8%A7%D9%84%D8%B9%D8%A7%D8%A6%D9%84%D8%A9_%D8%A7%D9%84%D8%A8%D8%A7%D8%B0%D9%86%D8%AC%D8%A7%D9%86%D9%8A%D8%A9\"><\/span>2. Clearing the field of weeds of the Solanaceae family<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Plants in the same tomato family (Solanaceae or nightshades) and spontaneously germinating tomato plants can also serve as hosts for Alternaria species. It can transmit the infection to tomato plants.<\/p>\n\n\n\n<p>This is true for edible crops like potatoes, as well as hairy gooseberries, black gooseberries, and nettles, so be vigilant and keep these weeds out of your garden.<\/p>\n\n\n\n<p>When removing weeds and autoflowers, be sure to destroy them \u2013 don&#039;t put them on the compost pile.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_%D8%AD%D8%A7%D9%81%D8%B8_%D8%B9%D9%84%D9%89_%D8%AC%D9%81%D8%A7%D9%81_%D8%A7%D9%84%D9%86%D8%A8%D8%A7%D8%AA%D8%A7%D8%AA\"><\/span>3. Keep the plants dry<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Late blight spores require a lot of moisture to germinate. Since tomato plants are accustomed to growing in dry climates, they are unusually sensitive to water on their leaves, making them more susceptible to fungal infections than many other crops.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Take every precaution possible to reduce the amount of moisture on your tomato plants. In the presence of germs, this can help prevent the fungal infection from getting worse.<\/li>\n\n\n\n<li>Try to avoid spraying plants on or around plants directly with water in wet weather.<\/li>\n\n\n\n<li>Using drip irrigation instead of watering from above will help keep the plants dry.<\/li>\n\n\n\n<li>Installing plants on stakes contributes to treating early blight in tomatoes. When your plants are installed vertically, this helps create better air flow around them, which helps them stay dry. Another benefit is that there will be less contact between the leaves and the soil that can be damaged. Contaminated with germs, pruning the branches at the bottom of the plant will also help. However, don't wait until the tomatoes are fully grown to install them. Where you should place the stakes at planting time. Because if you install them later, you will risk damaging the roots.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_%D8%A5%D8%B2%D8%A7%D9%84%D8%A9_%D8%A7%D9%84%D9%86%D8%A8%D8%A7%D8%AA%D8%A7%D8%AA_%D8%A7%D9%84%D9%85%D8%B5%D8%A7%D8%A8%D8%A9_%D9%88%D8%A5%D8%AA%D9%84%D8%A7%D9%81%D9%87%D8%A7\"><\/span>4.
