Barnyardgrass control in conventional and Clearfield rice grown under intermittent flooding

Crop, Forage &Turfgrass Management, Volume 9, Issue 2, December 2023., 2023
Abstract In the mid‐southern United States, rice (Oryza sativa L.) is flooded primarily to suppress weed germination and growth. Two experiments were conducted to determine whether herbicide performance in conventional or Clearfield rice weed control programs was affected by intermittent flooding.

Selectivity of Cyhalofop-butyl in Poaceae Species.

Journal of Weed Science and Technology, 1998
Responses to foliar-applied cyhalof op-butyl of the seedlings of 29 Poaceae species at about 3- to 4-leaf stage were examined. Species belonging to subfamilies of Panicoideae, except for Imperata cylindrica, and Eragrostoideae were all susceptible, being completely controlled at 100g ha-1.

Resistance of barnyardgrass biotypes (Echinochloa crus-galli) to ACCase-inhibiting herbicides in the main rice-growing regions of the state of Santa Catarina, Brazil [PDF]

Ciência Rural, 2023
: The resistance of Echinochloa crus-galli (barnyardgrass) to cyhalofop-p-butyl has already been confirmed in rice fields in Santa Catarina, Brazil. However, it is not known if this resistance affects other ACCase inhibitors.

Herbicide‐resistant barnyardgrass (Echinochloa crus‐galli) in global rice production

Weed Biology and Management, Volume 23, Issue 1, Page 23-33, March 2023., 2023
Abstract Barnyardgrass (Echinochloa crus‐galli (L.) Beauv.), an annual species of the family Poaceae, is a major weed problem in rice‐producing countries throughout the globe. Synthetic herbicides can effectively control this grass in rice paddies, but the development of resistant biotypes after the continuous use of the same active ingredients has led

Assessing Potential Environmental Impacts of Pesticide Usage in Paddy Ecosystems: A Case Study in the Deduru Oya River Basin, Sri Lanka

Environmental Toxicology and Chemistry, Volume 41, Issue 2, Page 343-355, February 2022., 2022
Overuse of pesticides has led to the violation of the balance between food security and ecosystem sustainability. Abstract Rice paddies are unique ecosystems that provide rich wetland habitat. Their enduring existence across vast stretches of land has led them to evolve into unique systems serving a diverse assemblage of organisms and sustaining a ...
