Phytophthoriosis and its symptoms

Аннотация

Phytophthora is a dangerous enemy of solanaceous crops, that tomatoes, potatoes, peppers, eggplants and physalis belong to. Late blight impairs fruits, leaves and plant stems. Its fungus becomes particularly active in the increase of air moist, especially when dew falls; with temperature fall in day time; in thick plantation of solanaceous crops. Late blight often threatens the plants in the period between the end of July and beginning of August.
