Georgopoulos and Vomvoyanni, 1965

Conidia (asexual reproduction) from 6-10 day old cultures of the phytopathogenic fungi Hypomyces (Fusarium) solani f. cucurbitae, Sclerotium rolfsii and Penicillium italicum did not show germination or at most a low germination rate when they were incubated for 6 days at 25 °C in potato-dextrose-agar containing 153.6 mg/l of 1,2-dichloro-3-nitrobenzene.

 

Gamliel et al., 1989

Gamliel et al. (1989) found EC50 values of 15.6 mg/l and 10.6 mg/l regarding the inhibition of growth of Fusarium oxysporum and Rhizoctonia solani respectively. The incubation period was not reported.

 

Richardson, 1968

Richardson (1968) studied the fungistatic effect of 1,2-dichloro-3-nitrobenzene vaporizing at 24 °C from non-sterile, humidified compost. For the inhibition of growth of Phythium ultimum (after 24 hours incubation) as well as Rhizoctonia solani and Trichoderma viride (both after 48 hours incubation) he found the following EC50 values:

P. ultimum: EC50 = 225 mg/l

R. solani: EC50 = 125 mg/l

T. viride: EC50 = 350 mg/l
