- The results provided a reasonable basis for classified management of wheat scab.
- It was remarkable that epidemic of wheat scab was affected by both the climatic factor and the underground water level and displayed complex geographic patterns.
- Adopting the simplex-barycenter design, optimal mixture ratio among carbendazim and triadimefon and thiophanate-methyl which control wheat scab acre studied in this paper.
- In accordance with field investigation to epidemic dynamics of wheat scab,the forecast method for differential equations of epidemic state has been given respectively.
- Sumai 3 and Huzhuhong 2 were only indicative of highly disease-resistant, whereas Haidong539 and Qingchun7 and 23 were middle disease resistant, the rest 67 varieties (or lines) all represented middle degree or high degree susceptibility to wheat scab.
- The disease resistance of 72 varieties (or lines) of wheat to wheat scab in Qinghai existing agricultural production has been identified by field plot experiment at present for two years.
