This disease has been first reported in 2906 in France; in South-Eastern Europe it was first reported in 1944 on the onion crops and in 1969 on the leek crops. This bacteria causes significant damage in seed crops, but it also severely damages consumer crops, both in the field and inside warehouses.
Tomato leaf mold – Cladosporium fulvum
The disease is common in greenhouse and solarium tomato cultures and is rarely encountered on field crops.
Sugar Beet Leaf Spot – Cercospora beticola
Sugar beet leaf spot is the most widespread disease in sugar beet crops. It is encountered every year and can damage up to 50% of the crops during years with favorable conditions.
Septoria leaf spot – Septoria lycopersici
Septoria leaf spot is a widespread disease in countries with temperate and oceanic climate, and besides tomatoes, it infests other grown or spontaneous plants from the Solanaceae family.
Fabraea Leaf Spot – Fabraea maculata
The disease, also called Entomosporium Leaf Spot, is common in nurseries and orchards. The fungus parasitizes on quince trees and pear trees, and more rarely on apple trees, medlar trees or rowan trees. In years with frequent rainfalls during summer, the disease becomes very harmful in the nurseries.
Angular Leaf Spot – Isariopsis griseola
The disease is observed more frequently in humid areas, where it causes serious damage.
Bacterial Soft Rot – Erwinia carotovora var.carotovora
This disease was first signaled in America and today it is widely spread on all crops. In Europe, this disease has been signaled around 1947-1948 and it causes damage both on field crops and on warehouse-stored plants.
Violet Root Rot – Rhizoctonia violacea
This disease is wide-spread in many European countries. It was spotted in South-Eastern European countries in 1929. It is worth mentioning that this disease does not cause a lot of damage.
Potato blackleg – Erwinia carotovora pv. atroseptica
This disease can affect both crop potatoes and warehouse stored potatoes, leading to a tubercle loss up to 50-60% of the production.
Brown rot – Monilinia fructigena
The disease affects over 40 plant species from different families, but is more threatening for the apple and pear tree. The brown rot disease causes damages to the fruits closer to their maturity and the late infestations which happen during harvesting occur in storehouses.
Tomatoes Powdery mildew – Leveillula taurica
The disease has been known for a long time in Europe but extended in the northern part in the 20th century. It’s a disease that brings serious damages to tomatoes crops in countries which cultivate tomatoes.
Tobacco Powdery mildew – Erysiphe cichoracearum
The disease is relatively spread in countries that grow tobacco from Europe, USA, Asia and Africa and may cause serious damage through the foliage’s depreciation.
