| Abstract: | Studies on optimum mixture proportion of Ripcord (10EC). omethoate(40EC)and BT in controlling Leaf-eating pests in fruit trees have been carried out by applying simple method centre of gravity design. Under the condition of content control effect >80%. Cost <60yuan/ha,single insecticide type, two insecticides mixed type and three insecticides mixed type, three types all told, four optimization plans were chosen, which includes 46 kinds of optimum mixture proportion. There are 42 kinds of two insecticides mixture and 4 kinds of three insecticides mixture. |
