Protac SF®  is a new residue free solution for pest control. It employs a purely physical mechanism to control crop pests. Protac SF® contains polymeric substances, primarily silicone polymers. Once applied to crops, these compounds create a specific structure – a thin, sticky net – on the body surface of pests. On a molecular level, it is a three-dimensional polymeric net. The structure immediately immobilizes pests and rapidly eliminates them.

Protac SF® is perfectly suited as correction measure in any Integrated Pest Management plan. It is an alternative to chemical pest control methods.

Protac SF® has proven to be very effective against numerous insects

As demonstrated by both scientific research and the practical experience of growers, Protac SF® is highly effective in combating pests such as spider mites, aphids, psyllids, white flies, thrips.

How does Protac SF® work?

The polymeric silicone net structure that forms on body surfaces of pests following application of Protac SF®, immobilizes the insects that feed on plants. It blocks their physical life functions in multiple ways and quickly leads to the death of herbivorous insects and mites.

Dead insects may remain attached to leaves for a few days. After that time they fall off, for example during rainfall.

Unlike most traditional plant protection products, Protac SF® combats pests by employing a purely physical mechanism rather than interfering with their biochemical life processes. Therefore Protac SF® does not contain any active chemical ingredients. Ultimately it is impossible for the insects to become resistant.

How to use Protac SF®

Protac SF® has a wide range of applications. It is intended for use for vegetable cropsfruit trees and berries, ornamental plants. Always read the label carefully before use. The recommended dilution rates are on the label.

  • Always spray on dry crop.
  • Protac SF® needs to dry quickly; relative humidity below 65% if possible.
  • Do not use if rain is expected within 6 hours.
  • Protac SF® should be used at first sign of pest. If necessary, treatment should be repeated after 7 days if insects appear again.
  • Do not mix Protac SF® with other substances before consulting your Biobest Expert
