Effect of Controlling Rice Stripe Disease and Its Virus Vector Insect, Laodelphax striatellus (Fallén) by Seedling Box Treatmentwith Pymetrozine Granules under High Infection Pressure. SHIMIZU Nobutaka (Fukuoka Agriculture and Forest Research Center,Chikushino, Fukuoka 818-8549, Japan) Bull. Fukuoka Agric. For. Res. Cent. 5:1-4 (2019)
Rice stripe disease, one of the most serious diseases affecting rice plants, is caused by the Rice stripe virus (RSV). Since the 2000s,
outbreaks of rice stripe disease have been increasing in some parts of the Fukuoka prefecture. In addition, populations of its virus vector
insect, the small brown planthopper (SBPH), Laodelphax striatellus (Fallén), have increased in the Fukuoka prefecture. Moreover,these insects have exhibited low susceptibility to imidacloprid and fipronil, the main insecticide components against SBPH. Therefore,
the effect of controlling the rice stripe disease and the SBPH by seedling box treatment with pymetrozine granules was examined. The
study was conducted in the areas of the Fukuoka prefecture with high rates of infected SBPH. After two years of examination, treatment
with the pymetrozine granules reduced the density of SBPH and the occurrence of rice stripe disease in comparison with the fipronilgranules. Thus, it can be suggested that the seedling box treatment with pymetrozine granules is an effective method against rice stripe
disease, even under high infection pressure.
