You have precisely framed the issue. Bio-decoctions like Panchagavya or Dasagavya are often touted as great out of the world solutions, sometimes presented as morning religious rituals. The reality, however, is guided by the size of the problem.

The Problem vs. Solution Disconnect

We must remember the core reality: In the first place, the problem is just not there. And if a mild infestation does occur, it is never as big as it is presumed.

• The Overkill: Formulating and applying these complex decoctions involves significant time and effort. This effort is often wasted because the home garden's natural balance means the pest problem is simply not intense enough to require such complex intervention.

• Mental Satisfaction: These elaborate decoctions are best viewed as good mental satisfactions—a way for the gardener to feel maximally engaged in holistic farming, which is a noble goal.

The Power of Simplicity: Plain Water Bathing

Before resorting to any formulated spray—even organic ones—remember the most effective, low-hassle solution that you have observed:

• The Simple Cure: Plain water bathing (a gentle, but firm spray of clean water) can be very effective in controlling soft-bodied pests, dust, and mild fungus. This is the zero-cost, zero-effort solution.

The Contextual Conclusion

The biological complexities resulting in pest infestations are not yet understood so well. While these solutions are powerful—and on large farms the dynamics are different, and the pest problems are real and intense—for your small, home garden:

Using them is good, but not using them is also ok.

If a problem persists, the complexity of the solution often fails anyway, confirming the principle that the home gardener should rely on simple hygiene, patience, and the option of plant removal, rather than becoming a formulist.
