Example. With Compound No. 1 - 3-isoprop w 2D, 3-benzotnadiazinone- (4 -) - 2,2-cyoxenec at a dose of .322 g / l, compound No. 2 5-chloro-3- (2 hetragiaropyronyl) 6- Methyluralyl at a dose of 1.01 g / l and with a mixture of compounds No. I and No. 2 at a dose of 4.27 + 1 g / l were treated with plants with a height of oi 5 to 15 cm, such as chicken millet, mokrita, Bedgrain and chamomile. Moreover, the compounds and their mixture were tested at various concentrations, namely, 100%, 67%, 43%, 26.5%, 16.5%, 9.7%, by diluting the preparation with water. After eight weeks, the herbicidal activity was recorded on a nine-point scale: 9 — no damage; About - full of death plants.
