Effects of Nitrofen, Metoxuron and Methabenzthiazuron on Growth and Uptake of S³⁵ by Wheat

A solution culture experiment was carried out to investigate the inluence of four herbicides viz. nitrofen, terbutryne, metoxuron and methabenzthiazuron on the growth and sulphur uptake of wheat variety Kalyan Sona at Haryana Agricultura University, Hissar. Wheat seedlings were exposed to complete nutrient solutions containing S⁸⁵ (as H₂ SO₄) and graded concentrations (0, 0.6, 1,2, 2.5 and 5.0 ppm) of her bicides for 10 days.

All the herbicide treatments decreased the dry weight of both root and shoot per plant. The reduction in dry matter production of wheat was minimum in case of nitrofen at all the dosages tried. With the increasing levels of herbicides sulphur uptake of plant decreased but root to shoot transport of sulphur increased.
