Echinochloa crusgalli

Bio-control using pathogens holds promise mostly in non-cropland situations because of the slow pace of control of weeds and the wider window for control as compared with the shorter window of the cropping season and associated disturbances under cropland situations. However, in aquatic systems they appear to be more realistic, due to the absence of such cropping barriers and enhanced mode of dispersal in water. Among the wetland weeds, Echinochloa crusgalli and Cyperus rotundas are being... 

MC (Medicago sativa) (Echinochloa crusgalli) (Lolium perenne)... 

Barnyard grass (Echinochloa crusgalli (L.) Beauvois) Wild oat (Avena fatua Linnaeus)... 

The most important members of this group include Pennisetum americanum (pearl or bulrush millet), Panicum miliaceum (proso or broomcorn millet), Setaria italica (foxtail or Italian millet), Eleusine coracana (finger or birdsfoot millet), Paspalum scorbiculatum (kodo or ditch millet) and Echinochloa crusgalli (Japanese or barnyard millet). 

In addition to the 8 Ib/acre tests, several compounds with prominent preemergence activity were retested at either 0.12, 0.25, 0.5, or 1.0 Ib/acre on the following plant species, as well as the five species listed above barnyard grass (Echinochloa crusgalli), velvetleaf (AbutiIon theophrasti), wild oat (Ayena fatua), zinnia... 

As a preliminary bioassay, some alkali metal salts of (9-aIkyl 1-(substituted phenoxyacetoxy)aUtylphosphonic acids IIA-IIE were tested for herbicidal activity on barnyard grass (Echinochloa crusgalli) and cabbage type rape (Brassica napus) by the Petri dish method. For further herbicidal activity evaluation, most of... 

As a preliminary bioassay, the inhibitory activity of cyclic 1-hydrox-yalkylphosphonates IVA and IVB against barnyard grass (Echinochloa crusgalli) and cabbage type rape Brassica napus) were tested by using Petri dish methods. The inhibitory effect of IVA and IVB against the growth of roots and stems of tested plants were examined. The results are listed in Table 5.5. 

At this stage, the inhibitory activity of several optically active compounds IA-8, IC-5 and IC-22 including their racemates, R) and (5) enantiomers against rape (Brassica napus) and barnyard grass (Echinochloa crusgalli) were examined at 100 and 10 mg/L, respectively. Results are listed in Table 6.19. 

Test Plants Brassica napus L. (rape) and Echinochloa crusgalli (barnyard grass).
