Abstract:

Experiments were carried out at Vegetable

Research and Development Station Bacau during

2011 – 2012, in tomato cultivated in tunnels.

In the climatic conditions of 2011 – 2012

years the following pathogens have been observed:

- Cladosporium fulvum - Tomato Leaf Mould

- Alternaria sp. – Early blight (brown spotting of the

leaves of tomato).

- Phytophthora infestans - Downy mildew, Tomato

blight.

Tomato Leaf Mould was observed on tomato

plants at the following cultivars:

- Amonita, frequency of attack (FA%) - 90%

intensity of attack (IA%) 84% degree of attack

(GA%) 75.6%.

- 5.5.C, FA% - 18.8%, IA% - 21.5%, GA% - 4.1%.

- Abelus, FA% - 40%, IA% - 46.9%, GA% - 18.8%.

- Inima de bou, FA% - 100%, IA% - 25%, GA -

25%.

The variety Inima de bou was the most

sensible to disease, with a 100% frequency of attack

and 25% intensity of the attack. This cultivar was

followed by the hybrids: Ammonita GA% - 75.6%,

Abelus GA% - 18.8% and 5.5.C, GA% - 4.1%.

Alternaria sp. had lower attack:

- 1.1.C; AF% 50% IA% - 9.4% GA% - 4.7%.

- Inima de bou, FA% - 100; AI% - 9.4% GA% -

9.4%.

Due to high temperatures and low humidity,

downy mildiew had a lower attack, as:

- 1.1.C F% - 30% I% - 3.2% GA% - 0.9%.

- L 15, F% - 10% I% - 12.5% GA% - 1.3%.
