Dear Sri Jagadish,

You can use Phosforic acid in to your drip system @ 1 ltr per 5,000 R.mtrs, through ventury . feed the acid and stop the ventury and keep the drip system untouched for at least 12 hrs.

With this , the laterals and drippers gets cleaned.

With best wishes,  g.p.rao,    farmer

Tx      G.P. Rao for your suggestion. where shall I get phospheric acid.
