Iprobenfos
쵾
Introduction: Iprobenfos is systemic organophosphorous fungicide, which inhibit normal development of the thalli by interfere with the membrane permeability of the cell. Control of leaf and ear blast (Pyricularia oryzae), stem rot (Helminthosporium spp.) and sheath blight (Rhizoctonia solani) in rice. Phytotoxicity Non-phytotoxic to rice. Injury has been noted on beans, soya beans and aubergines.

ENVIRONMENTAL FATE
Animals: Three metabolites were identified in urine and faeces of rats. Soil: DT50 15d (two soils). Koc 5030. Plant: For metabolism in plants.
Usage: Iprobenfos was introduced by Kumiai Chemical Industry. It is a systemic fungicide to control fungal diseases on rice.
Application: Mode of Action Systemic fungicide with protective and curative action. Absorbed through the roots and leaves. Translocation and metabolism in the rice plant have been reported (H. Yamamoto et al., Agric. Biol. Chem., 1973, 37, 1553). Uses Control of leaf and ear blast (Pyricularia oryzae), stem rot (Helminthosporium sigmoideum, Magnaporthe salvinii) and sheath blight (Rhizoctonia solani) in rice, applied at 5000-8500 g/ha.
