Properties of controlled-release formulation of pyrimisulfan as a one-shot herbicide in a paddy field

Pyrimisulfan is a novel sulfonanilide herbicide with high herbicidal activities against major troublesome weeds in paddy fields. To use this chemical compound as a one-shot herbicide for rice, we have developed a controlled-release formulation, pyrimisulfan-1 kg granule (containing 6.7 g a.i.). This...

Summary:Pyrimisulfan is a novel sulfonanilide herbicide with high herbicidal activities against major troublesome weeds in paddy fields. To use this chemical compound as a one-shot herbicide for rice, we have developed a controlled-release formulation, pyrimisulfan-1 kg granule (containing 6.7 g a.i.). This granule formulation applied at pre-emergence to the three-leaf stage at 10 kg/ha efficiently controlled troublesome weeds, such as Echinochloa spp., perennial weeds, and sulfonylurea-resistant weeds. Furthermore, pyrimisulfan-1 kg granule exhibited consistent herbicidal efficacy under simulated overflow conditions. Therefore, pyrimisulfan-1 kg granule is suitable for use as a one-shot herbicide and is an effective tool for rice cultivation systems requiring reduced pesticide applications.
