Eckert, 1962

Eckert studied the phytotoxic effect of 1,2-dichloro-3-nitrobenzene on 6 days old seedlings of cucumber (Cucumis sativus) and mung bean (Phaseolus aureus) that grew at 25°C and in darkness on a moist sandy soil containing the test substance and nutrient solution. The seeds of the mung bean were germinated on filter paper 24 hours prior to the test starting. Following toxic values were obtained:

Cucumber: EC50 = 96 mg/l (fresh weight)

Mung bean: EC50 = 73 mg/l (fresh weight)

 

Lynn and Thiegs, 1944

The treatment of field bindweeds and grasses by spraying them with an aqueous emulsion containing 162 g/l of dichloronitrobenzene (58 % 1,2-dichloro-4-nitrobenzene, 37 % 1,2-dichloro-3-nitrobenzene and 5 % other dichloronitrobenzene isomers) and with an application rate of 220 g/m² led to the withering of the leaves and flowers. The herbicidal effect persisted for the seasonal growth period.

Description of key information

For transported isolated intermediates according to Reach, Annex XVIII, this endpoint is not a data requirement. However, data is available for this endpoint and is thus reported under the guidance of "all available data".
