SDK Subsidiary Develops New Rice Herbicide

December 3, 2001

SDS Biotech K.K. (SDS), a consolidated subsidiary of Showa Denko K.K., has developed a new rice herbicide benzobicyclon that is very effective in removing tough annual broad leaf weeds.

SDS obtained registrations for benzobicyclon and six types of benzobicyclon-containing formulations in April this year.

The advantages of this new herbicide are as follows:

  • 1.The herbicidal action lasts as long as 40-50 days.
  • 2.Especially effective in removing weeds having resistance to sulfonyl-urea-based herbicide.
  • 3.Highly safe for rice.
  • 4.Required dosage per unit area has been reduced to one-tenth that of existing herbicides of SDS.
  • 5.Friendly to the environment because chemicals with low solubility in water and low toxicity to fish have been selected. (Outflow of herbicide-containing water from paddy field is minimized.)

SDS is promoting the following three types of formulations that contain benzobicyclon (but do not contain sulfonyl urea) as highly effective agent for removing a wide range of weeds:

1. Kusakonto FL (flowable)

This product has been developed jointly with Sankyo Co., Ltd. for application to sulfonyl-urea-resistant weeds. This product is sold solely by Sankyo.

2. Smart FL

One-shot herbicide for early post application. To be put on the market tomorrow by Kumiai Chemical Industry Co., Ltd. and Nihon Bayer Agrochem K.K.

3. Focus-shot (jumbo-granule)

A jumbo-granule herbicide for early post application. In 2002, this product will be upgraded to a one-shot jumbo granule herbicide and placed on the market. It will contribute to the saving of labor through application of ten 50g packs in 1,000 square meters of paddy field. Joint development with Kaken Pharmaceutical Co., Ltd.
