The effects of two types of commercial pesticides on the rice quality were investigated under the low volume aerial application. It could provide guidance for the pesticide application and choose the right types of pesticides. For chlorpyrifos and hexaconazole pesticides, aerial and traditional spraying on Nangeng 5050 rice was used during the growing season. The differences of postharvest rice quality and also the kernel spectrum of DMA between aerial application in high concentration and low volume and traditional spraying were investigated. It was found that rice kernel hardness for aerial application with chlorpyrifos was higher than tradition spraying application but no significant difference with hexaconazole application. With X-ray diffraction analyzer, it was found that the effect of aerial application was smaller than traditional one for the microstructure of rice kernels.
