| Abstract: | In this paper. we establish a related model which reveals the relationship betweenthe wheat yield loss and the spontaneous attack by varieties of wheat diseases and pest insects. Of many kinds of wheat diseases and pest insects.wheat aphis and white dust diseaseare asserted as main factors affecting wheat yield.lowering the thousand granulars weightand the amount of grains of a single plant. Main while.the integrated control indices areproposed concerning various kinds of wheat diseases and Pests. |
