Echinochloa Phyllopogon

 

(formerly E. oryzicola), an annual plant of the family Gramineae. The stems reach a height of 120 cm. The leaves are rough and measure up to 1 cm across. The inflorescence is a panicle, and the one-flowered spikelets are distributed in groups of two, three, or four. E. phyllopogon grows as a weed in rice fields; it ripens at the same time as the rice. Its grains contaminate the soil and the seeds of rice; since its shoots resemble rice shoots, control of the weed in its early stages is difficult. In the USSR, E. phyllopogon is found in rice-growing regions, predominantly in the Caucasus, Middle Asia, and the Far East. The plant is often united with or is regarded as a subspecies of E. oryzoides.

Harvesting of mixed stands can probably explain the inclusion of some minor constituents, but not the occurrence of the main crops, like Echinochloa colona and Panicum turgidum, which grow in separate stands.
Rahman and Ungar (1994) determined that the distribution of Echinochloa crus-galli on a saline pond border was limited by salinity stress in the lower high-salinity zone and by competition with Atriplex prostrata in the upper low-salinity zone.
They evaluated the allelopathic potential of a-phenylacetic and p-ethoxybenzoic acids using Echinochloa crusgalli and Sesbania exaltata as test species.
It was found that average inhibition by the variety Duchungjong on Echinochloa crusgalli was 77.
