The advantage of TBZ + iprodione treatment for control of grey mould decay of celery caused by the heterogenic spore population of Botrytis cinerea in Israel.

A combined thiabendazole (TBZ) + iprodione (as Rovral 50 WP) treatment was more effective in inhibiting in vitro growth of B. cinerea isolates obtained from decayed celery cv. Tender Crisp than either of the fungicides alone. When applied prior to inoculation, the combined treatment prevented decay by TBZ-sensitive/iprodione tolerant isolates and reduced initial decay by the TBZ-tolerant/iprodione sensitive isolates to 3-10% of the level with no treatment. Under natural infection conditions iprodione showed better decay control than TBZ, and at 1500 micro g/ml it reduced initial decay during prolonged storage to 3% of the no-treatment level. Although TBZ (500 micro g/ml) or iprodione (1000 micro g/ml) applied separately reduced decay significantly, the combination of lower concn of each fungicide was sufficient to eliminate decay development almost totally. The combined treatment also inhibited decay caused by Sclerotinia sclerotiorum, which contributed 3% of the total soft rot in stored celery.
