Abstract:North of Zhejiang Province is a main bamboo-producing district. The bamboo forest is not only in large areas, but also has a concentrated distribution. In recent years, as many bamboo suffer damage by Algedonia coclesalis, Circobotys aurealis, Eumorphobotys obscuralis, Demobotys pervulgalis, Crocidophora evenoralis, Hippota dorsalis, Eutomostethus nigritus, Aiolomophus rhopaliodes, Otidognathus davidis etc. A large part of bamboo stands have withered and become chloratic, some bamboos even died. This cause farmer‘s enormous economic losses. After testing for many years, it is clear that injecting Tamaron into bamboo carity to control the vatious bamboo insect pests reached a mortality of over 95%. The residue of Tamaron in the bamboo shoots of current year contains some residual Tamaron with the highest amount on the tenth day after injection and gradually decreasing day by day. The residue of Tamaron could not been found in the bamboo shoots coming out next year. Even the highest amount of the residue of Tamaron on the tenth day after injection is only 23.8—47.5%, which is lower than the standard for edible vegetable.
