The soluable pesticides injected into the trunk can transported insides to every part of the tree to kill pests. The change of pesticides inside the tree was observed. The result showed that injecting pesticides once a year could kill above 80% of the pests which happened once annually. The effect of injection lasts longer than that of applying the pesticide outside. The pesticides injected into the tree are not affected by environment and do not kill natural enemies directly,and the residual amount of pesticides is below the international standard level.展开更多
