Similar products of sodium nitrophenolate include potassium nitrophenolate and ammonium nitrophenolate. The difference between them and sodium nitrophenolate is that the ions connected to the hydroxyl group on the benzene ring are different, the physical properties are slightly different, and the chemical properties and biological activities are roughly the same. The application in agricultural production is roughly the same. Because the physical properties of sodium nitrophenolate are more stable, most of them use sodium nitrophenolate.

【13】Notes

①When the concentration is too high, it has inhibitory effect on crop buds and growth.

② It can be used in combination with pesticides and fertilizers, and the effect is better.

③ Stop using tobacco leaves 30 days before harvesting.

④ Store in a cool place.
