A series of 17 new derivatives of 2-(2,4,5-trichlorphenoxy)propionate acid was synthetized and tested on pesticide activity. All compounds showed high activity against dicots at 5 kg a.s./ha. Eight compounds were tested in the II stage screening-test. The compounds had a good herbicidal efficacy only at higher dose (2.5 kg a.s./ha), when the dose decreased to 1,25 kg a.s./ha activity was strongly...
The management of a waste of FMG production by glycine method is presented in the paper. Perzocyd 75 SL is effective for monocotyledonous and dicotyledonous weeds control. It can be used for vegetation control in non-crop lands and for reclamation. The best results were obtained when the preparation was applied to fully developed plants in spring and summer treatments.
The synthesis of the new derivatives of 1,3,5-triazine was presented. The obtained compounds were biologically evaluated under glasshouse conditions. Some of them showed phytocidal activity on the bio indicators in pre- and post-emergence treatments. Compound IPO-11407 (2-methoxy-4-methylamine-6-thioalkyl-l,3,8-triazine) was distinguished by good phytocidal activity and was qualified to the II-nd...
Examination of biological activity of 537 new chemical compounds against algae and duckweed was the experimental objective. Among compounds studied only four revealed algicidal activity. They were as follows: dodecyldimethyl(5-hydroxyazomethine-2-methoxy)benzylammonium chloride (IPO--6773); 1,2-dimethyl-3-dodecyloxymethylimidazolium chloride (IPO-8958); 1-octyl-3-octyloxymethylimidazolium chloride...
The mixture containing 48% propachlor and 12% trifluralin was chosen on basis of the studies reported. Herbicidal formulation Propalin 60 WP was elaborated. The herbicide is characterized by broad spectrum of activity and low cost of treatment and is recommended to control burdensome weed species in rape.
