Effect of (C6H5)3PbCl and (C6H5)3SnCl on delayed luminescence intensity, evolving oxygen and electron transport rate in photosystem II of Chlorella vulgaris.

The effect of the organometallic compounds containing lead, (C6H5)3PbCl , and tin, (C6H5)3SnCl, on Chlorella green algae photosystem II was studied. Suspension of the algae treated with (C6H5)3SnCl at concentrations of 1.0 and 4.

Influence of an adjuvant on the distribution of herbicides in a sediment/water system.

This study concerned the influence of a mineral oil adjuvant used as tank-mix, on the sorption of commercially formulated compounds in soil using a laboratory-scale sediment/water system. The laboratory experiment was conducted with the adjuvant Atpolan 80 EC and the triazine herbicide atrazine and isoxaflutole which belong to the isoxazole class of herbicides. Ditch bed sediment was the medium.

Comparison of some adjuvants efficacy with azoprim and buramet using chlorophyll fluorescence.

This paper presents a quick chlorophyll fluorescence method for the estimation of the influence of some adjuvants applied with Azoprim 50WP (a.s. atrazine) or Buramet 70WG (a.
