Ronstar® 250 EC Bayer

Ronstar® 250 EC is a selective pre-emergence herbicide from Bayer, containing Oxadiazon (20g/kg), Quartz Silica (9-92 g/kg), and Surfactants (up to 100%). Developed through Bayer's herbicide research, this emulsifiable concentrate provides season-long weed control in rice, vegetables, and ornamental crops.

Drawing on Bayer's expertise in oxadiazinone chemistry, Oxadiazon inhibits protoporphyrinogen oxidase, preventing chlorophyll synthesis in germinating weed seedlings. Ronstar® 250 EC demonstrates exceptional efficacy against annual grasses and certain broadleaf weeds. The product offers extended residual activity through soil incorporation, maintaining weed-free conditions throughout critical crop establishment periods. Refer to the product label for locally registered crops, target weed species, and application protocols in your region. Particularly effective in rice paddies and transplanted vegetables, Ronstar® 250 EC represents Bayer's commitment to providing growers with reliable, selective weed management solutions.
