Summary The effect of chlorsulfuron on uptake of 45 Ca was studied in maize ( Zea mays L. cv. Earliking) plants grown from seeds dusted with 1, 8 naphthalic anhydride (NA). 45 Ca absorption in sand‐grown maize was significantly decreased when chlorsulfuron was applied to the foliage but this was not so when seeds had been dusted with NA. Uptake of 45 Ca was also reduced when either root or shoot soil zones were separately exposed to chlorsulfuron. When seeds had been dusted with NA, uptake of 45 Ca from main roots was similar to that of untreated plants, but only when chlorsulfuron was localized in the shoot zone. NA did not counteract the severe reduction in 45 Ca absorption when chlorsulfuron was localized in the root zone.
