Application of silic improving the resistance to the disease caused by Piricularia oryzae on rice.

Nacentech HCM
Result Piricularia oryzae:
  • Piricularia oryzae – Treat sodium silicate with concentrations of 50 – 300 mg SiO2/liter
    (referencing treatment concentrations: 600 – 20.000 mg SiO2/lít) did not exhibit an inhibitory effect on the growth
    and development of P. oryzae under in vitro conditions.
  • The fertilizer dose of 80 mg SiO2/kg soil and foliar at a concentration of 400 mg SiO2/liter gave the highest results in limiting the damage of disease, improving the growth of rice and seed yield.
  • Separate application of silic fertilization into the soil (80 mg SiO2/kg soil/crop). foliar (400 mg SiO2/liter/spray 3 times/crop) or combining root with foliar fertilization has the effect of reducing the damage of disease and improving the growth of rice plants.
