Outline of Final Research Achievements

In order to establish a pesticide-free measure during the transplant production period, deoxidant-induced anoxia was tested for controlling agricultural pests without any degradation of transplants. As the results, adult survival and egg hatchability of two Tetranychus spider mites reached 0% when anoxia duration was longer than 12 h. Under this condition, leaves of kidney been and strawberry transplants showed physiological disorders, whereas newly-developed leaves were normal.
