Colletotrichum acutatum belongs to polyphagous fungal pathogens and is widespread in many countries on all continents. C. acutatum causes the most serious economic damage in strawberry (Fragaria x ananassa Duch.). Considering the wide variability of the pathogen may be assumed spread to other areas which constitutes danger not only for strawberry, but also other economically important fruit crops, vegetables and fruits.
The main objective of our study was to verify the cross infection of eleven C. acutatum isolates from different host plants (strawberry, safflower, lupine, pepper and Hypericum perforatum) to selected host plants (strawberry, pepper and safflower). Two varieties from each of the experimental plant species were selected and virulence of isolates C. acutatum was evaluated.
Based on results of statistical evaluation, virulence of C. acutatum isolates was different on strawberry, pepper and safflower. The strawberry variety Pegasus was more susceptible to C. acutatum than the variety Elkas. Isolate 710 from H. perforatum showed the highest virulence for both varieties in terms of index of infection intensity. The pepper variety Pirouet was more susceptible than the variety Cynthia. The highest degree of virulence was found for isolate 29267 from pepper in the variety Cynthia, the highest virulence was proved for isolate 231 from strawberry in the variety Pirouet. No statistical difference was confirmed between susceptibility of the safflower varieties. Isolate 1209 from safflower showed the most important effect on tested plants of safflower.
Isolates 710 from H. perforatum, isolate 1209 from safflower, isolate 29267 from pepper and isolate 231 from strawberry showed different virulence for tested host plants.
