FERSIL enhance the effectiveness of agricultural chemicals including herbicides, insecticides, fungicides and plant growth regulators.

FERSIL is particularly effective when used with water soluble and post- emergent herbicides. Spray solutions formulated with FERSIL will complately wet virtually any leaf surface. FERSIL has also been shown to increase the amount and the rate of uptake of water soluble herbicides. This results in more consistent weed control. Enhanced herbicidal efficacy has been most evident on broadleaf and woody brushweed species. FERSIL has been shown to be less effective in enhancing performance on perennial grass weed species.

New Generation Super Spreading Agent

Surface-active agents are chemicals that reduce the surface energy of a material to which they are added by absorption at the air/liquid interface. Surface tension can be considered in various ways, but perhaps best as a result of the forces of attraction existing between the molecules of a liquid. It is measured by the force per unit length acting in the surface at right angles to an element of any line drawn in the surface (mN/m). Of the various surface-active chemistries currently available, we mainly concentrate on a class of materials called silicone polyethers. The three most common molecular structures for silicone surfactants are rake-type copolymers, ABA copolymers and trisiloxane surfactants. FERSIL is a silicone polyether copolymer with 550 molecular weight, all EO polyether type, H end group trisiloxane molecular architecture.

Comparison with conventional adjuvants;

FERSIL spray adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants. FERSIL (0,1 %) gives an aqueous surface tension of 20nM/m, on the other hand a TDA containing 12EO units nonionic surfactant at 1,0% gives a surface tension of only 30nM/m. Because FERSIL spray adjuvant is a superspreading agent, the contact angle of spray solutions on leaf surface is reduced, leading to an increase in spray coverage.

How to use

  • FERSIL should be added directly into spray tank and agitated to ensure proper mixing. Application rates should be consistent with the manufacturer label. For optimum performance, spray solutions containing FERSIL should be applied within 72 hours mixing.
  • FERSIL can be also used in different industries such as; personal care application, textile, ink & coating or any other areas where wetting and spreading is desired.

Potential Applications

FERSIL spray adjuvant has been used successfully in spray applications globally.
