Pre-emergence-TestPre-emergence test
Lösungsmittel: 5 Gewichtsteile Aceton Emulgator: 1 Gewichtsteil AlkylarylpolyglykoletherSolvent: 5 parts by weight of acetone emulsifier: 1 part by weight of alkylaryl polyglycol ether
Zur Herstellung einer zweckmäßigen Wirkstoffzubereitung vermischt man 1 Ge¬ wichtsteil Wirkstoff mit der angegebenen Menge Lösungsmittel, gibt die ange¬ gebene Menge Emulgator zu und verdünnt das Konzentrat mit Wasser auf die ge¬ wünschte Konzentration. Samen der Testpflanzen werden in normalen Boden ausgesät. Der Boden wird nach 24 Stunden mit der Wirkstoffzubereitung begossen bzw. gespritzt. Dabei hält man die Wassermenge pro Flächeneinheit zweckmäßigerweise konstant. Die Wirk- stoffkonzentration 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 %To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration. Seeds of the test plants are sown in normal soil. After 24 hours, the soil is watered or sprayed with the active ingredient preparation. 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%
