The stem borer is one of the most difficult pests to control for rice farmers. It can affect crops at any stage of growth. To solve this issue of chewing pests, Bayer created Regent ULTRA. It can be used as foliar and granules against difficult-to-kill pests like early shoot borer, stem borer, leaf folder, and termites.

Bayer Regent ULTRA contains fipronil. It is a powerful, high-performing insecticide that protects crops such as wheat, rice, and sugarcane. Applying it helps paddy crops grow better, with more tillering and higher yields.

Regent ULTRA through its active ingredient fipronil, a phenyl pyrazole insecticide, acts by disrupting nerve impulse transmission by interfering with the flow of chloride ions through the gamma amino butyric acid (GABA) regulated chloride channel.

This disruption affects the CNS activity, ultimately resulting in the death of the insect.
