Agrisil K50 is a potassium silicate based liquid fertilizer for silica supplementation in all crops.
Key benefits
Regular application of Agrisil K50 to plants has three key benefits for all plant types:
  • It improves plant tolerance to cold and heat stress, reducing damage and losses;
  • High silica content = thicker cell walls - makes it harder for biting and sucking insects to cause damage to plants; and
  • Thicker cell walls = less wilting and improved shelf-life after harvest/picking (and potentially better prices if you’re selling on).

This product is non-toxic agricultural input with no Maximum Residue Limits requirements. It is Non-toxic and residue free.
