Influence of Echinochloa crus-galli density and emergence time on growth, productivity and critical period of competition with dry-seeded rice

International Journal of Pest Management, 2021
Echinochloa crus-galli (L.) Beauv. is a stronger competitor of rice for resources than other weeds. An adequate knowledge of the biology, ecology and critical period of competition of E.

Lipid biochemistry of echinochloa crus-galli during anaerobic germination

Phytochemistry, 1984
Abstract Seven day old seedlings of Echinochloa crus-galli var. oryzicola (Vasing) had a higher total lipid content when germinated under N 2 than in air, although ungerminated seeds contained more lipid than either seedling. The triacylglycerol pool was not depleted under anaerobiosis as it was in air and only air-grown seedlings showed a net ...

Effect of Fulvic Acid on Barnyardgrass (Echinochloa crus-galli) Seedling Growth under Flooding Conditions

Weed science, 2021
Barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] is a problematic weed in rice (Oryza sativa L.) fields. Overapplication of herbicides causes environmental pollution and the emergence of resistant weeds, and integrated weed management methods can ...

Pollen‐mediated transfer of herbicide resistance in Echinochloa crus‐galli

Pest Management Science, 2014
AbstractBACKGROUNDPollen‐mediated gene flow (PMGF) can facilitate the dispersal and spread of herbicide resistance from one weed population to another within an agricultural landscape. The aim of this study was to quantify the extent of PMGF in Echinochloa crus‐galli (barnyardgrass), an important herbicide‐resistant weed species in the United States ...

Non-target-site resistance mechanism of barnyardgrass [Echinochloa crus-galli (L.) P. Beauv.] to florpyrauxifen-benzyl.

Pest Management Science, 2021
BACKGROUND Florpyrauxifen-benzyl (FPB) is an arylpicolinate herbicide (Group IV) for barnyardgrass control in rice. One susceptible (Sus) and three putative FPB-resistant (R1, R2, and R3) barnyardgrass biotypes were selected based on resistant ...

Geographic variation in seed dormancy among populations of Echinochloa crus-galli

Oecologia, 1996
In 1991-1993, we investigated the incidence of seed dormancy in 25 local populations of barnyard grass, Echinochloa crus-galli (L.) P.Beauv., in the western Czech Republic. The percentage of germination after 4 months afterripening of dry seeds at 25°C varied between 0.0 and 83.6%. Although there were significant annual differences in the percentage of
