تأثير المبيدات الفطرية على الفلورا الفطرية لترب حقول الرز

الملخص EN

This study was carried out to determine the effect of concentrations gradient of benomyl and and mancozeb fungicides on mycoflora of rice field soils.

Results showed that many fungi appeared less in soil before treatment with fungicides than after treatment, such as Fusarium spp., Absidia sp.

and Alternaria spp.

While the common fungi in the soils declined after treatment with fungicides such as Penicillium and Aspergillus.

The results also showed that lower concentrations of benomyl (10,100 ppm) gave strong inhibitory action against Non-Rhizosphere fungi, Rhizosphere fungi and Rhizoplane fungi compared with mancozeb concentration action at 500 and 1000 ppm.

Key words: Soil mycoflora, rice, fungicides
