1. Increase seed germination

After seed treatment, it not only can improve seed vigor & germination rate, but also can stimulae the seeds immune & growth system to improve the diseases resistance & growth rate.

It has been experimentally demonstrated that we apply on rye grass seed, its germination index increased 33.5% and vitality index increased 59.5%.

improve seed germination rate

2. Increase resistance ability to stress & diseases

For stress, it can induce plants general regulation of endogenous hormones.

  • Improve plant’s water retaining capacity
  • increase the lodging/drought-resistance
  • Help the recovery of damaged plants

For diseases, it can thicken the plant’s cell walls and instantly induce defense reactions to various kinds of virus, fungus and bacteria.
