Lösungsmittel: 5 Gewichtsteile Aceton Solvent: 5 parts by weight of acetone
Emulgator: 1 Gewichtsteil Alkylarylpolyglykolether Zur Herstellung einer zweckmäßigen Wirkstoffzubereitung vermischt man 1 Gewichtsteil Wirkstoff mit der angegebenen Menge Lösungsmittel, gibt die angegebene Menge Emulgator zu und verdünnt das Konzentrat mit Wasser auf die gewünschte Konzentration.  Emulsifier: 1 part by weight of alkylaryl polyglycol ether To prepare a suitable preparation of active compound, mix 1 part by weight of active compound with the stated amount of solvent, add the stated amount of emulsifier and dilute the concentrate with water to the desired concentration.
Mit der WirkstofEzubereitung spritzt man Testpflanzen, welche eine Höhe von 5 - 15 cm haben so, daß die jeweils gewünschten Wirkstoffmengen pro Flächeneinheit ausgebracht werden. Die Konzentration der Spritzbrühe wird so gewählt, daß in 2000 1 Wasser/ha die jeweils gewünschten Wirkstoffmengen ausgebracht werden. Nach drei Wochen wird der Schädigungsgrad der Pflanzen bonitiert in % Schädigung im Vergleich zur Entwicklung der unbehandelten Kontrolle. Es bedeuten: Test plants with a height of 5 - 15 cm are sprayed with the active substance preparation in such a way that the desired amounts of active substance are applied per unit area. The concentration of the spray liquor is chosen so that the desired amounts of active compound are applied in 2000 l of water / ha. After three weeks, the degree of damage to the plants is rated in% damage compared to the development of the untreated control. It means:
0 % = keine Wirkung (wie unbehandelte Kontrolle) 0% = no effect (like untreated control)
100 % = totale Vernichtung  100% = total annihilation

Samen der Testpflanzen werden in normalen Boden ausgesät. Nach 24 Stunden wird der Boden mit der Wirkstoffzubereitung begossen. Dabei hält man die Wassermenge pro Flächeneinheit zweckmäßigerweise konstant. Die Wirkstoffkonzentration in der Zubereitung spielt keine Rolle, entscheidend ist nur die Aufwandmenge des Wirkstoffs pro Flächeneinheit. Nach drei Wochen wird der Schädigungsgrad der Pflanzen bonitiert in % Schädigung im Vergleich zur Entwicklung der unbehandelten Kontrolle. Es bedeuten: Seeds of the test plants are sown in normal soil. After 24 hours, the active ingredient preparation is poured onto the floor. The amount of water per unit area is expediently kept constant. The concentration of active substance in the preparation is irrelevant, the only decisive factor is the amount of active substance applied per unit area. After three weeks, the degree of damage to the plants is rated in% damage compared to the development of the untreated control. It means:
