Foliar Uptake and Movement of Chlormequat in Cereals: Influence of Dose and Addition of Related Chemicals

Increased amounts of chlormequat applied to leaves of barleyand wheat resulted in a greater proportion being taken up andmoving to the tips of treated leaves. Combined foliar applicationwith certain other amines also increased uptake and movementof chlormequat - choline and glycine betaine were particularlyeffective - but a few others had the reverse effect. Ammoniumand sodium salts of acetic, butyric and hydrochloric acids alsoincreased movement of ¹⁴C-chlormequat Hordeum vulgare L., barley, Triticum aestivum L., wheat, chlormequat, foliar uptake
