A gyomirtószer jelölt vegyületeket hagyományosan és logikus módon a célgyomokon tesztelik.

A jó gyomirtó hatása specifikus, így gyakorlatilag csak egyetlen gyomirtó-gyom páros tesztelhető hatékonyan. Ugyanakkor a szűrővizsgálaton részt vevő vegyi anyagok sok más gyomra hatásosak lehetnek akkor is, ha arra az egy vizsgáltra nem hatásosak.

Ezért fordultak a kutatók az érzékeny békalencséhez. Ha a békalencse azt mutatja, hogy a szer hatékony, meg lehet próbálni különféle gyomokra, vagy a békalencse kísérletek alapján ki lehet deríteni a szer hatásmechanizmusát és abból előrejelezni, hogy mire lesz hatásos.

Az ilyen szűrővizsgálatokhoz nagyszámú tesztelés szükséges, melyet mikrotitráló lemezeken végeznek, ahol egyszerre 96 teszt végezhető el és az értékelés is automatizálható.
