本发明所介绍的是防治抗性黑尾叶蝉的优良药剂,它由异稻瘟净分别与马拉硫磷、稻丰散复配而成。自1960年开始发现黑尾叶蝉对马拉硫磷产生了抗性以来,仅在数年之后,这种对有机磷类杀虫剂均有抗性的害虫就蔓延开来,扩展到整个日本西部地区。此后,曾相继使用西维因、害扑威、速灭威、叶蝉散、丁苯威、灭杀威和残杀威等杀虫剂加以代替。可是到了1969年前后,这些氨基甲酸酯类农药也同样产生了抗性。至今,抗性黑尾叶蝉的危害已遍及全国,近乎无药可治。
The present invention introduces the excellent medicament for preventing and controlling the resistance of the rice leafhopper, which is prepared from the mixture of the different rice blast net and the malathion and the rice hopper respectively. Since 1960, when the resistance of the leafhopper to malathion has been found to be resistant, it is only in a few years that the pest, which is resistant to organophosphate insecticides, spreads and extends throughout Japan Western Region. Since then, they have been using Xiweiyin, parasite, monosodium glutamate, leaf cicada, butadiene, carbofuran and propoxine to replace pesticides. However, by around 1969, these carbamates also gave rise to resistance. So far, the harm of resistant rice leafhopper has spread throughout the country, almost no cure.
