Ascochyta blight, which is caused by the fungus Ascochyta fabae f. Sp. Lentis, is
considered as a very important fungal disease that infects lentils and cause it damage.
The experiment was conducted in ICARDA research station for agricultural exper
iments in
the orchard area Basha, Jableh, Lattakia in four varieties of lentils that are grown in
different parts of Syria, and these varieties are: Idleb 2, Idleb 3, Idleb 4, and municipal red.
Artificial infection was performed using a local isolation of the fungus Ascochyta lentis
with an average of three times and ten days between each infection and the other. The
infectious vaccine adopted a concentration of 105 Båge / ml.
This field study was carried out at EL- Gab Research Center during furing
2000-2001. Six fungicides namely, Benomyl 50%, Difenoconazole, Diniconazole,
Fludioxonile, Triticonazole and Thiram 37.5% + Carboxin 37.5% with high
doses×1, ×2, ×4, ×8 were
used as seed dressings on chickpea cultivar Gab3 to
study their effects on Ascochyta blight infection.
The results showed that fungicides eradicated the infection from the seeds
and protected the seedlings from infection. There was a clear effect on delaying
the infection by ascochyta blight on chickpea for about 10-15 days in
comparison with the untreated control. However, Higher doses of some
fungicides negatively affected the yield.
