Pesticide efficacy evaluation on nitenpyram to control of rice brown plant hopper

In this paper, plot and field demonstration experiment of applying nitenpyram to control rice brown plant hopper were carried out. The results showed that 4 g 50% nitenpyram SG per 667 m² could control rice brown planthoppe efficiently. Its fast-acting and persistence efficacy were significantly higher than 25% pymetrozine WP, 25% thiamethoxam WDG and 100 g/L ethiprole SC, being safe for rice growth. The yield of rice in demonstration area was 6.2% higher than that in control area. So, it was suggested that nitenpyram and carbosulfan-imidacloprid could be alternately used to control rice brown plant hopper.
