Onion is one of the most important commercial crops grown all over the world. The crop is attacked by many diseases which cause yield losses and result in lowering the quality and export potential of the produce. Stemphylium blight caused by Stemphylium vesicarium (Wallr.) Simmons is one such disease, which has become a serious problem since past few years, especially in Northern and Eastern India. Foliar application of fertilizers and biorationals is gaining popularity. So, their effect on the pathogen Stemphylium vesicarium was assessed. In vitro study was conducted for testing these chemicals at different doses. The results of the study revealed thaturea was most effective in inhibiting the fungal growth at all the tested concentration. It was also found that soluble NPK and Potassium nitrate promoted the fungal growth at all the concentration. Among biorationals, bromonitropropanol gave the highest mycelial inhibition (73.72%), while sodium and potassium bicarbonates at lower concentration promoted the fungal growth, but inhibited the growth at higher concentration. These results provide the insight about the possible effects that foliar spray of fertilizers and biorationals can have on the fungal pathogen and their potential use in the disease management strategy under field conditions.

Keywords: Stemphyliumvesicarium, Biorationals, Fertilizers, Inhibition, in vitro, Urea.
