Tomato "Pantano"

Rarely a gardener can boast that he is unfamiliar with late blight - this fungal disease initially appears on potato leaves, and then the infection spreads to tomatoes...
The first signs of the disease are brown spots appearing on the leaves and stems of tomatoes, and in wet weather a faint white coating appears on the underside of the leaf. Subcutaneous brown blurry spots form on the fruits, which quickly increase in size and cover the entire fruit. The affected tomato first becomes hard and then softens. Moreover, the infection persists in tomato plant debris.
What should you do if this scourge affects tomatoes?
In rainy and cold summers, preventive measures are especially necessary: every two weeks, tomatoes are sprayed with preparations containing copper (CHOM, Oksikhom). The first time - seedlings, the second time - before planting them in open ground, and the third time - two weeks after planting.
If for some reason this was not done, then at the first signs of late blight, the bushes are treated with a 10% solution of table salt. As a result, a protective film is formed on the fruits, preventing the penetration of the fungus, the causative agent of the disease.
Fresh kefir, which is stirred in a bucket of water (1 liter of kefir per 5-7 liters of water), will help prevent late blight for quite a long time. The resulting solution is sprayed on tomatoes two weeks after planting the seedlings in a permanent place, and then every week.
But the most effective, of course, will be biological protection - FITOSPORIN (titers of special bacteria that “eat” pathogenic late blight).
