Abstract: Sosnovskio barščio kontrolės eksperimentas atliktas 2016 m. Varluvoje (54°59'37.36", 23°55'12.38"), Kauno r., purškiant atskirus augalus herbicidais ir jų mišiniais (15 variantų). Didesnės glifosatų normos (2160, 2880 ir 3600 g ha-1) praėjus 14 d. po purškimo sunaikino Sosnovskio barščio lapus ir chlorofilo indeksas buvo nenustatytas. Praėjus 28 d. po purškimo augalai sunyko juos purškiant glifosatu 1440 g ha-1, glifosato 720 g ha-1 + dikambos 480 g ha-1, glifosato 720 g ha-1 + fluroksipiro 180 g ha-1, glifosato 720 g ha-1 + triasulfurono 4,0 g ha-1 bei triasulfurono 4,0 g ha-1 + fluroksipiro 90 g ha-1 mišiniais
Control experiment of Sosnowskyi's hogweed (Heracleum sosnowskyi) carried out at Varluva (54°59'37.36", 23°55'12.38") Kaunas region, in 2016 by spraying individual plants with sole herbicides and their mixtures. The experiment included 15 treatments: 1. Glyphosate 1,440 g ha-1, 2. Glyphosate 2,160 g ha-1, 3. Glyphosate 2,880 g ha-1, 4. Glyphosate 3,600 g ha-1, 5. Glyphosate 720 g ha-1 + dicamba 480 g ha-1, 6. Glyphosate 720 g ha-1 + fluroxypyr 60 g ha-1 + clopyralid 35 g ha-1 + MCPA 450 g ha-1, 7. Glyphosate 720 g ha-1 + fluroxypyr 180 g ha-1, 8. Glyphosate 720 g ha-1 triasulfuron + 4 g ha-1, 9. Dicamba 960 g ha-1, 10. Dicamba 480 g ha-1 + fluroxypyr 180 g ha-1, 11. Dicamba 480 g ha-1 + triasulfuron 4 g ha-1 12. Fluroxypyr 360 g ha-1, 13. Triasulfuron 8 g ha-1, 14. Fluroxypyr 120 g ha-1 + clopyralid 60 g ha-1 + MCPA 600 g ha-1, 15. Triasulfuron 4 g ha-1 + fluroxypyr 90 g ha-1. During the experiment every two weeks, five times during the growing season was estimated plant height (cm) and chlorophyll index before the spraying. It shows the intensity of photosynthesis, and hence the viability of the plant. In this article presented the changes of chlorophyll index. In the experiment the higher glyphosate rates (2,160; 2,880 and 3,600 g ha-1), 14 days after spraying destroyed Heracleum sosnowskyi leaves and was impossible to measure chlorophyll index. The plants were destroyed 28 days after spraying with glyphosate at the rate of 1,440 g ha-1, and with mixtures of glyphosate 720 g ha-1 + dicamba 480 g ha-1, glyphosate 720 g ha-1 + fluroxypyr 180 g ha-1, glyphosate 720 g ha-1 + triasulfuron 4 g ha-1, and triasulfuron 4 g ha-1 + fluroxypyr 90 g ha-1. Mixtures of glyphosate 720 g ha-1 + fluroxypyr 60 g ha-1 + clopyralid 35 g ha-1 + MCPA 450 g ha-1, dicamba 480 g ha-1 + fluroxypyr 180 g ha-1, fluroxypyr 120 g ha-1 + clopyralid 60 g ha-1 + MCPA 600 g ha-1, and sole dicamba 960 g ha-1 was not effective for Heracleum sosnowskyi control
