Control of wheat stripe rust and ensuring high yield of crops under planting of wheat variety mixtures.

Wheat stripe rust has become the most dangerous disease which threaten safe yield of wheat in Sichuan Province.It is meaningful to provide technique support for integrated disease control by exploring the effective control measures of wheat stripe rust.Wheat stripe rust dynamic developments of all-planting and mixed-planting have been systematically investigated in this study by taking different mixed-planting combinations among 6 wheat varieties with different resistance levels.The results of this experiment show that the mixed-plantings of 4 and 6 wheat varieties can delay the occurance of wheat stripe rust,slow the speed of disease and decline the damage of disease as well as stabilize yield of wheats.
