The field control effect experiment results showed that the three main insect pests of rice (stem borer, rice leaf roller and plant hopper) can be controlled effectively by 40 % V.irtako WG of 8-10 g/667 m^2. 40 % Virtako WG can be extended in large area as its advantages: the duration of the protective efficacy longer, not so strict requirements for the spraying time, safe to rice production.
