a large number of products with the trichloroisocyanuric acid (TCCA) rice seed packaging placed on the market

According to "Pesticide Management Regulations" provisions for agriculture seed disinfection products must obtain pesticide registration certificate.  trichloroisocyanuric acid (TCCA) in the domestic marine bio-engineering Co., Ltd. and other enterprises in Hunan Province to obtain pesticide registration of pesticides for rice seed disinfection.
Mixtures of granular trichloroisocyanuric acid (TCCA) (CDB 90®Olin Corporation, Stamford, Conn.) with 2 parts by weight of Guar gum; and with10 parts by weight of Guar gum (Aldrich Chemical Co., Milwaukee, Wis.), thetrichloroisocyanuric acid being the only other component, were prepared by blending. A tabletting die (2.5 cm.dia.) was charged with 14 grams of the each of the mixtures and the mixtures compressed on a Carver press (Laboratory press, Model B, Sterling, Inc., Menomonee, Wis.) at 9,000 psi to produce a tablet of each mixture. To determine the disintegration rate of the tablets, a tablet was placed into an 8 oz. jar filled with tap water (25° C.) and the time measured for the tablet to completely disintegrate and disperse the trichloroisocyanuric acid (TCCA)  to form a mound of trichloroisocyanuricacid granules at the bottom of the jar. The disintegration time of the tablets containing 2 percent by weight and 10 percent by weight of guar gum was less than 1 minute.
Currently in the province of rice seed sales market, we found a large number of products with the  trichloroisocyanuric acid (TCCA) rice seed packaging placed on the market. With these rice seeds sold TCCA products, with the exception of marine bio-engineering Co., Ltd. in Hunan Province to obtain pesticide registration certificate, the rest of no pesticide registration. Reflecting prominent are the label Nanning Chemical Industry Co., Ltd. honor products, Guilin Lingui West chemical plant, chemical plant west of the city of Guilin Lingui dispensing of TCCA. The product label on the bag disinfection health card number, but did not obtain pesticide registration. Further packaging label Lingchuan County of Guangxi Baofeng Chemical Plant, Nanning Chemical Group Co., Guanyang factory packing of seed disinfectant products were not obtained registration of pesticides, such products used in agricultural production, especially seed disinfection does not meet " pesticide management regulations "requirements.
