Resumen

Fusarium proliferatum has been reported on garlic in the north west U.S.A., Spain and Serbia, causing as water-soaked tan lesions on cloves. Moreover, F. proliferatum is known to produce a range of toxins, including fumonisin B1, moniliformin, beauvericin, fusaproliferin and fusaric acid, which are implicated in pathogenesis. In this study six randomly selected F. proliferatum isolates from garlic were tested for pathogenicity and screened for fusaric acid production. Healthy seedlings of onion (Allium cepa), leek (A. porrum) and chives (A. schoenoprasum) and garlic clones (A. sativum) were inoculated. Onion seedlings and garlic clones were soaked in the conidial suspensions of each F. proliferatum isolate for 24 h and then planted in flats containing soil previously inoculated with the same isolate of F. proliferatum. Plants were maintained in a temperature and light-controlled greenhouse (12 h/12 h light/dark; 25/21°C). The root and bulb/clove rot disease symptoms were graded into five classes following the method of Stankovick et al. (2007). A disease severity index (DSI) was calculated as the mean of three plants of each species and four test replicates. Symptoms on onion and garlic plants were observed three weeks after inoculation. The overall effects of isolate, host and variety were analyzed. Effects were significant for all the studied isolates. The correlations between isolate pathogenicity and production of FA are also discussed .
