Interaction between saflufenacil and imazapyr+imazapic in the management of barnyardgrass and weedy rice and selectivity for irrigated rice [PDF]

Ciência Rural
: The use of imidazolinone-tolerant rice cultivars allows selective control of weedy rice and barnyardgrass. However, in many situations, there is a need to add herbicides from other chemical groups to increase the spectrum of weed control. In this sense,

Rice and Barnyardgrass: Water Stress and Initial Establishment

American Journal of Plant Sciences, 2017
The present work aimed to evaluate the effect of different water stress levels on the development of both rice and barnyardgrass. The study was established into greenhouse, in completely randomized design, in factorial scheme 2 × 5, with four replications. Factor “A” comprised the plant species (rice cv.

The Leaf Anatomy of Barnyardgrass (Echinochloa crusgalli Beauv.)

Journal of Weed Science and Technology, 1968
In the previous report the author pointed out that the number of roots on both nodes, coleoptile and the first leaf, in barnyardgrass (Echinochloa crusgalli) was clearly less than those of rice plants.Present report is an anatomical survey on the leaf blade and leaf sheath in barnyardgrass seedlings.

First report of barnyardgrass resistant to glyphosate in Brazil

Advances in Weed Science
Abstract Background Barnyardgrass (Echinochloa crus-galli (L.) P. Beauv.) is an annual weed affecting many field crops. A glyphosate-putative-resistant barnyardgrass population was found from a soybean field in southern Brazil. Objective This study aimed to confirm this resistance in Rio Grande do Sul (RS) and identify its mechanism.

Echinochloa spp response to preemergence and postemergence herbicides in California rice (Oryza sativa L.)

Frontiers in Agronomy
Historically, herbicides were used for Echinochloa spp control in California rice production which led to the selection of herbicide-resistant biotypes. Field surveys were conducted across the seven major rice-growing counties in 2020 and Echinochloa spp
