【Abstract】 The results of the chemical experiments showed that all 5% Regent, 40.7% chlorpyrifos, 50% Daominqing, 20% chongkeshou and 50% Lewudi had the higher efficiency on the control of rice Tryporyza Incertulas, and they can be used alternately. But Regent did not fit to be used alone on the control of the third generation of Tryporyza Incertalas and it can be used together with Triazophos. Applied practice showed it can control the damage of Tryporyza Incertulas through the selection of chemicals (or formula) with higher efficiency in time in case of the serious occurrence of Tryporyza Incertulas.更多还原
