Heuer, B. (Volcani Center, Bet Dagan (Israel). Inst. of Soils and Water)
Very low concentration of metolachlor, such as 1.75 x 10 sub (-7) M, considered to be non-toxic was found to inhibit vital processes in cucumber (Cucumis sativus) seedlings. Photosynthesis, leaf area and leaf conductance were reduced by 16 percent as compared with non-treated plants. Protein content remained unchanged, suggesting direct inhibition of the photosynthetic apparatus
