Abstract:
Cytoplasmic uptake of carbendazim (methyl benzimidazol‐2‐yl carbamate; MBC) from an aqueous solution was demonstrated with isolated mesophyll cells. About 2.5% of the labelled MBC (ring‐2‐[14C]) in the treatment solution (1.85 μg/ml) was taken up in 44 h. When cotyledons of cucumber seedling were treated with either 347 or 36 μg [14C]‐MBC/plant 1.11 and 0.13% were extracted, respectively, from the remainder of the plant, 5 days after treatment. Greatest amounts were detected in shoot apices. Likewise, when MBC and benomyl were applied at the dose of 2 μmol, 0.34 and 0.57% were detected in the untreated part of the plant with a bioassay procedure. Foliar application with 347 or 36 μg[14C]‐MBC/leaf resulted in the translocation of 1.68 and 0.11% out of the treated area. By scalding the living cells of the petiole translocation was prevented suggesting that long distance movement occurred in the symplast. During a period of 14 days 1.56% of [14C]‐MBC applied to cucumber leaves was metabolised and respired as CO2. This degradation was assumed to occur enzymically within the symplast.
