Abstract
During the last decade certificate registration of 13 active ingedients were removed by European Union from sunflower herbicide market, including the basis for the incorporating technology, the trifluralin active ingredient as well. Its relative, the benfluralin active ingredient, which include the Balan 600 WDG herbicide product in sunflower, will be sold again from 2015 spring in Hungarian pesticide market. It has a broad-spectrum and lond residue besides it has very high level selectivity on sunflower. It has very good effect against annual monocotweeds such as common barnyadgrass, foxtail species, large crabgrass and wild proso millet, dicotyledonous weeds such as common lambsquarters,and redroot pigweed. It has significant side-effect against common ragweed, black nightshade, wild buckweed and prostrate knotweed. The long effect residue provide the weed-free til harvest. Benfluralin is totally selective on sunflower, as no colouring, any deformation or growth inhibition was not observed during the entire growing season. It should be sprayed 3-4 days before sowing within 1 hour and to be incorporated into the soil in 4-6 cm depth with tillage equipment. It can be used in tank mix with fluorochloridon in incorporated technology against annual dicotyledonous weeds. After the Balan incorporation can be used postemergence timing imazamox and tribenuron-metil active substances against hard kill and deeply germinating weeds. The products can not be used in tank mix with bacterial products.

Summary
Az elmúlt évtizedben 13 hatóanyagot vontak ki a napraforgó gyomirtásából, köztük a bedolgozásos technológia alapját, a trifluralint. A benfluralin hatóanyagú Balan 600 WDG bedolgozásos napraforgó gyomirtó készítmény 2015 tavaszától újra elérhető lesz a magyar kereskedelemben. Széles és hosszú hatásspektrummal rendelkezik, nagyfokú szelektivitás mellett. Kiváló hatékonysággal rendelkezik a magról kelő egyszikű gyomok közül a kakaslábfű, muhar fajok és a vadköles ellen, a magról kelő kétszikű gyomok közül a fehér libatop és a szőrös disznóparéj ellen, míg markáns mellékhatással a parlagfű, fekete csucsor, ugari szulákpohánka és porcsin keserűfű ellen. A magról kelő kétszikű gyomok ellen tankkombinációban együtt lehet használni fluorkloridon tartalmú készítménnyel. Balan-os bedolgozást követően állománykezeléssel imazamox vagy tribenuron-metil hatóanyagú készítménnyel a nehezen irtható, mélyről csírázó gyomok is megoldhatóak. A készítmény nem keverhető a legfontosabb baktérium tartalmú talajoltó készítményekkel
