Allelopathy on selected major crops. Many crop cultivars show strong allelopathic properties, of which rice ("Oryza sativa") has been most studied. Rice allelopathy depends on variety and origin: Japonica rice is more allelopathic than Indica and Japonica-Indica hybrid. More recently, critical review on rice allelopathy and the possibility for weed management reported that allelopathic characteristics in rice are quantitatively inherited and several allelopathy-involved traits have been identified. Many invasive plant species interfere with native plants through allelopathy. A famous case of purported allelopathy is in desert shrubs. One of the most widely known early examples was "Salvia leucophylla", because it was
Scirpophaga gilviberbis on "Oryza" species, including "Oryza sativa". Scirpophaga gilviberbis Scirpophaga gilviberbis is a moth in the Crambidae family. It was described by Zeller in 1863. It is found on the Comoros and in the Democratic Republic of Congo, Kenya, South Africa, Zambia, India, Indonesia (Java, Sulawesi), Myanmar, Singapore, Thailand and Vietnam. The wingspan is 20–22 mm for males and 23–35 mm for females. The forewings of the males are ochreous with some fuscous scales. The hindwings are white, except for the costal area and the apex which are ochreous. Females have white fore- and hindwings. The anal tuft is whitish grey
