The control efficiency as affected by pesticide volumes (PV) , spraying approaches (fine spray, coarse spray) to the major pests and diseases  on rice plants at late growing stage were evaluated. For the rice neck blast, rice spikelet rot disease and leaf folder occurred at upper parts of rice plants, the best control efficiencies were obtained by two times of fine sprays(TFS), and the worst by two times of coarse sprays(TCS)  at the same pesticide application level and PV for a given rice variety. The control efficiencies by  the first fine spray and then coarse spray (FFSCS)  or the  first coarse spray and then fine spray(FCSFS) showed no significant difference. The control efficiency to japonica Xiushui 09 was better than that of  the indica/japonica hybrid combination Yongyou 12. For a rice variety at the same pesticide application level, the best control efficiency was obtained  at  PVs of 675 or 750 L/hm2, followed by 900, 1200, 450 L/hm2 and 225 L/hm2. For a variety at a given PVs, the best control efficiencies to sheath blight and planthoppers occurred on the middle and lower parts of rice plants, were gained by TCS, followed by FCSFS, FFSCS, and TFS. Control efficiency for  Xiushui 09 was better than that for Yongyou 12 at a given PV and by the same approach. For a variety by the same spraying means, the best control efficiency was obtained at the PV of 900 L/hm2, followed by 1200 and 750 L/hm2. The less water and the worse control efficiency   when the   PV was less than 900 L/hm2. The control efficiencies  to sheath blight and planthoppers were less than 50%   at the PV of 225 L/hm2. and  by TFS, especially for Yongyou 12. At the same pesticide application level, the control efficiency didn’t increase with the rising PV.
