Phosphine Fumigation Technology

Jul.04, 2017Keywords:grain fumigation, grain moisture, silo sealing

Now phosphine is widely used in grain dryer storage fumigation industry.

Phosphine mainly has below characters:

1. Small molecular weight, low boiling point, bigger density than air. Good performance for volatility, diffusivity and drill permeability inside grain bulk, can kill the insects in deep bulk and inside grain particle. 

2. Wide insecticidal spectrum, can kill insects effectively.

3. More available, with lower fumigation cost.

4. Can be easily dispersed after fumigation.

5. Almost no harm residual on the grain.

6. Require silo with perfect sealing performance and airtightness.

 For seeds fumigation, grain moisture should not be larger than below:
