Ethylene di urea (EDU) has been widely used as the ozone masking agent, but can the same or relevant impact can be measured with different doses of ascorbic acid as well.
Before attempting to evaluate the effect of ascorbic acid as a substitute for EDU, it is essential to workout economics of application of ascorbic acid. This ultimate objective of research has to be validated by economy. Many a time, highly valuable recommendations being effective in principle, do not get patronage from the farmers as they are cost prohibitive.
Thank you Rohit. Taken for granted that ascorbic acid is highly effective on crops as a masking agent in preference to EDU, it can not be recommended to farmers as a substitute for EDU, if ascorbic acid is cost prohibitive. My humble suggestion is to consider economics of ascorbic acid application.
