Abstract [Objective] The aim was to explore integrated control technology of disease pest and weed for wheat during whole growth period in Sanyuan. [Method] Integrated control experiment and demonstration of disease pest and weed for wheat during whole growth period were carried out in Sanyuan County. [Result] Using combined agents to treat seed was helpful for the growth of seedlings， and agronomic traits of treatment was better than control. The integrated control experiment field got significant controlling effects against disease and pest and yieldincreasing rate， that was seeds were treated by combined agents； herbicide was sprayed in spring； “onespraying and threecontrolling” technology of disease and pests were carried out from heading to filling stage. The “onespraying and threecontrolling” technology was carried out firstly when the heading rate reached 60%-70%， and applied secondly in seven days， good disease and pests controlling effect and yieldincreasing effect were got. [Conclusion] The results provide reference for the production of wheat in Sanyuan County.
