The predominant weed flora were Echinochloa crusgalli
on both Chorchorus olitorius (broad leaved weed) and Echinochloa crusgalli
(grassy weed) associated with soybean.
Therefore, this study aimed to determine the effects of salinity on germination and seedling emergence Malva neglecta, Echinochloa crusgalli
and Sorghum halepense has been done.
Field density: Echinochloa crusgalli
was the most abundant weed with a density of 5.
More than 90% frequency was estimated for the 9 taxa Alternanthera sessilis, Achyranthes aspera, Bauhinia variegata, Cassia alata, Cynodon dactylon, Lemna acquinoctialis Mikania indica, Mimosa pudica, and Trema orientalis, while Parthenium hysterophorus, Mallotus philippensis, Enhydra fluctuans, Echinochloa crusgalli
, Commelina bengalensis, Bauhinia variegata, Crotalaria pallida, and the fern Ampelopteris prolifera either touched 90% or was very close to it.
Eclipta prostrata, Echinochloa crusgalli
, Poa annua, Poa lanigera, Polygonum punctatum and Paspalum dilatatum are some of the exclusive species of this group.
The rice straw (RS) was collected from the local market and the German grass Echinochloa crusgalli
(GG) was cultivated in field plots at the Field Laboratory of the University.

They evaluated the allelopathic potential of a-phenylacetic and p-ethoxybenzoic acids using Echinochloa crusgalli
and Sesbania exaltata as test species.
Overall, depending on the herbicide type, mixing 50% RR of herbicides with 500A- of RV or WV dilutions can effectively control the weeds in paddy rice such as Echinochloa crusgalli
, Monochoria vaginalis and Scirpus juncoides without suppressing the growth, and yield of rice with acceptable soil impacts that promotes environment health.
The herbicidal activity resulted of the title compounds against Echinochloa crusgalli
and Brassica campestris were determined.
