Tomato is the most common and widespread vegetable among other vegetable crops in Uzbekistan. It ranks the first place by its planting area and gross yield. Tomato, like other farming crops, is affected by a number of infectious diseases. Among them, grey mould causes considerable damage to the crops. This article contains the data on testing fungicides with active ingredients Difenoconazole and Cyprodinil against grey mould disease of tomato in greenhouse condition. In fungicides sprayed variants, the inhibitory effect of fungicides on the development of diseases was considerable, that is, disease development index constituted 3.4-6.4%. When 0.08% concentration of fungicide Difen Super, 55% WP was applied, then development of disease was 3.9% at the first spray; and 4.5% at the second spray; 5% at the third and 5.8% at the forth spray. Among the fungicides, 0.05% concentration of Skor, 250 g/l EC fungicide applied variant performed much less development of grey mould disease compared to other variants, disease development index indicated 3.4-4.7%. According to experiment results, it has been recommended to conduct treatment with Difen Super, 55% WP (0.08%) and Skor, 250 g/l EC (0.05%) fungicides against tomato’s grey mould disease three times with 10 days interval.
