  1. Very good information. regarding preparation of home made pesticides for ocimum plant, plz inform gomootra and herbal hand wash may be used as pesticide.?

  2. Would be nice if you would SPECIFY THE AMOUNTS OF soap (dawn) to add, you don’t. “Add equal parts dawn & IA to 500ml water doesn’t tell me how much those “parts should be? Unless you mean 250ml ea? But if so, should state clearly! In recipe 1 says add 15-30 drops of neem oil to a mixture of water & dawn in a 1 liter bottle, but doesn’t say HOW MUCH DAWN should be in the liter? Is it 1/2 liter of water & dawn? That seems like a lot. Again, why, why, why not just SAY what it should be, PLEASE! These recipes are all but useless without specifics & really frustrating to spend time going to & reading this article only to find it doesn’t provide enough info to be useful. PLEASE FIX!!!
