Neporex® 2 SG

Neporex® 2 SG

Neporex®2 SG is a highly selective solution that is applied to the breeding sites of flies to control the larvae of the house fly and other fly species. House flies can transmit more than 100 human and animal disease-causing organisms¹, including avian influenza² and salmonellosis³. What if you could help control the development of flies before they become a problem for your operation? Now you can — with Neporex® 2 SG.

Key Features

  • A Novel Mode of Action — Featuring an insect growth regulator (IGR) for the control of fly larvae that disrupts the molting process, which is essential for the fly life cycle.
  • Environmental Impact —  The active ingredient, cyromazine, is from the triazine group, which as a family of pesticides is one of the least toxic to wildlife.4 It has no negative impact on beneficial insects when used according to the label.8
  • Flexible Application — Can be applied by spray or dry scattered on wet manure.

Choose Neporex® 2 SG for Your Fly Control

Spray or scatter water-soluble granules on wet manure to control nuisance flies at the larval state in breeding areas.

Novel Mode of Action for Fly Control

Neporex® 2 SG disrupts the molting process, which is essential for the fly life cycle. It also interferes with the chitin metabolism of fly larvae at all three stages,⁵⁻⁷ stopping these larvae from developing.

Impact to Well-Being

Neporex® 2 SG kills files. Fewer flies allow for more productive animals and may impact the animal's well-being.

Environmental Impact

Neporex® 2 SG has no negative impact on beneficial insects when used according to the label.⁸

Long-Lasting Effect

Neporex® 2 SG has a residual effect up to four weeks when used according to the label.⁷

Neporex® 2 SG Efficacy in the Field¹⁰

A recent study showed that Neporex® 2 SG provides strong control of M. domestica L. for up to four weeks — and possibly longer.

Figure 1 illustrates the number of adult flies that emerged after Neporex® 2 SG treatments were applied to poultry manure. While substantial numbers of adult flies emerged from the control manure, negligible numbers of adult M. domestica L. emerged from the Neporex® 2 SG-treated manure.
