Abstract: Rice sheath blight is one of the most important diseases on rice. The disease control efficacy of Jinggangmycin, the comman pestcide for the control of rice sheath blight now, is gradually decresed after its wide application for decades. In order to increase the control efficacy of Jinggangmycin, some pesticide adjuvants (silicon and oil) was studied. The results showed that the pesticide adjuvants could greatly increase its inhibit activity to the pathogen of rice sheath blight (Rhizoctonia solani ) and decrease the degradation speed of Jinggangmycin in rice leaves.
