Other claims from this paper (14)

Intervention effect Foliar post-emergent propanil destroyed Echinochloa crus-galli.
Intervention effect Foliar post-emergent propanil caused little or no visible injury to rice.
Intervention effect In propanil-treated rice leaves, dry weight and pigments temporarily decreased, with complete recovery in 4-5 days.
Intervention effect At lower concentrations propanil inhibited electron flow in both rice and E. crus-galli in a manner similar to DCMU.
Intervention effect At higher concentrations propanil damaged the primary electron donor in both rice and E. crus-galli.
Intervention effect In vivo chlorophyll a fluorescence kinetics after field spraying of 1% propanil confirmed progressive deterioration of the weed.
Intervention effect Propanil decreased fluorescence in rice leaves for a few hours.
Intervention effect Rice leaves showed partial recovery of fluorescence from propanil within 6 h of spraying.
Intervention effect Rice leaves showed total recovery of fluorescence from propanil within 48 h of spraying.
Intervention effect When leaves were infiltrated with 0.01% propanil, fluorescence recovered well in both weed and crop leaves.
Intervention effect When leaves were infiltrated with 1% propanil, fluorescence was drastically affected in both weed and crop leaves.
Intervention effect With 0.1% propanil, fluorescence in the weed leaves deteriorated progressively.
Intervention effect With 0.1% propanil, fluorescence in the crop leaves recovered after 4 h of incubation.
Mechanism The authors suggest that the crop has an effective endogenous detoxifying mechanism for propanil.
