Uptake of iprodione and control of diseases on potato stems

摘要

AbstractWhen applied to the roots of potato plants growing in different soils iprodione became systemic in the plants. Although iprodione was adsorbed on the soils tested, sufficient fungicide was present in potato stems to prevent infection byPhoma exiguavar.foveataon all plants except those grown in peat soils. The amount of fungicide present in the aerial parts of the plant was related to the soil/water distribution coefficients. Application of iprodione to the sprouts of seed potato tubers prior to planting decreased the incidence and severity of infection byRhizoctonia solani(stem canker) andPolyscytalum pustulanson stem bases.
