Previous reports have shown that fungicides affect endomycorrhizas. In the present work, the effects of several soil-applied fungicides were tested on plant growth, endomycorrhizal infection development and nutrient uptake in pot-grown soybean (cv. Amsoy 71) and micropropagated pineapple (Queen Tahiti and Smooth Cayenne varieties). Positive endomycorrhizal effects on shoot and root growth of soybean were unaffected by application of fosetyl-Al, captan and mancozeb ; however, benomyl and quintozen significantly depressed shoot growth of endomycorrhizal plants but significantly increased root growth. Mineral assimilation by endomycorrhizal plants was significantly greater than in nonmycorrhizal plants except for benomyl and quintozen application. Significantly higher values of endomycorrhizal infection were observed with trypan blue staining in fosetyl-Al and mancozeb treated plants. Benomyl and quintozen significantly reduced these values. No significant effect of any fungicide on endomycorrhizal pineapple growth was observed except for plants treated with etridiazol. Root/shoot ratio was inversed by the fungicide applications. Mineral uptake into shoots of both pineapple varieties increased in all endomycorrhizal plants and this positive effect was only slightly affected by fungicide application.
