Benefits of technology

This patented formula allows for uniform distribution of nifuramic acid (DNJ) or pyriminobenzil(pyrentezolbium)) powder throughout liquid solution containing ethylene glycol by mixing it together with another substance like sodium hydrogen carbonate. By doing this, we created suspending agents that could be applied on crop plants such as rice seeds without causing harmful side reactions during harvest time.

Problems solved by technology

This patents describes methods aimed towards controlling harmful organisms such as weevils (rice borne viruses), mites, mothges, fritts, nematodes, etc., particularly those caused by Phytophagidae spp. These techniques involve applying specific substances like pyracidebium to target areas where harm occurs due to attack from predators. However, there have been reports showing that both niclosporin A and pyricystabilisone were able to kill many types of beneficial microorganism species without causing any negative side reactions when applied alone.
