The processing of tomatoes from such diseases is carried out even at the very first stage - when preparing the seeds for planting.

Fungal diseases of tomatoes growing in a greenhouse and open ground are good, give in to treatment if they are sprinkled with ashes every three days. A handful is simply thrown up over the plants, so that the drug covers the foliage. This helps reduce the concentration of spores of phytophthora.
