Dose-response of pests to ethanedinitrile dose-response of weed seeds, soil borne pathogens, and plant-parasitic nematodes to ethanedinitrile

Abstract Ethanedinitrile is a chemical soil fumigant with promising efficacy against several key pests including weeds, nematodes, and soil-borne pathogens. The of 12 concentrations ethanedinitrile, ranging from 8.7 to 1,751 mg kg − 1 soil, control seeds tubers five weed species ( Cyperus esculentus, C. rotundus, Malva parviflora, Portulaca oleracea , Stellaria media ), two nematode Globodera rostochiennsis Tylenchulus semipenetrans four pathogenic fungal Fusarium oxysporum, Macrophomina phaseolina, Pythium ultimum Verticillium dahlia ) were evaluated in acidic sand (pH: 5.6) alkaline sandy loam 7.5–7.6), under controlled laboratory conditions. These pathogens weeds are common strawberry vegetable fields have been targeted by fumigants. was injected into microcosms for 24 h. Lower doses ethanedinitrile nematodes better than loam. However, the reverse tended be true as higher required Results showed that can provide excellent fungi,
