Red rice competition and control in cultivated rice
Studies were conducted to evaluate rice competitiveness with red rice and how to utilize glufosinate- and imazethapyr-resistant rice in water-seeded rice to control red rice. In the interference study, CL 121, Cocodrie, Drew, and Jasmine were seeded to obtain 95, 190, and 290 plants/sq m. Red rice …

Risk assessment of the transfer of imazethapyr herbicide resistance from Clearfield rice to red rice
Potential outcrossing between Clearfield rice and red rice will have a direct impact on the management and long-term usefulness of imazethapyr technology for rice weed control. The principal objective of this research was to determine the rate and agronomic consequences for outcrossing between …

CHROMOSOME AND GENOTYPE CHARACTERIZATION IN SOME RICE BIOTYPES SHOWING GRAIN SHATTERING
Red rice (Oryza sativa var. silvatica L.) is a common weed in rice crop, very troublesome to control due to high shattering. The aim of the present research was to analyse the genome of some biotypes of red rice in order to promote innovatives methods for its control. In the first year, …

Crescimento e produção de variedades de arroz vermelho em neossolo flúvico submetido a doses de esterco bovino
The decreasing in the productivity of red rice comes from the inadequate soil management coupled with the lack of technical guidance for the use of resources available in the properties as crop fertilization with proper use of manure as well as the lack of use of varieties promising for the …

Evaluation of Very-Long-Chain Fatty Acid-Inhibiting Herbicides in Arkansas Rice Production
… weeds, such as barnyardgrass and red rice in rice, there is a need for alternative herbicide sites of action. Very-long-chain fatty acid (VLCFA)-inhibiting herbicides are not labeled for use in U.S. rice production; however, this site of action (SOA) has been used with success in …

… the soil on the germination and early growth of red rice (Oryza sativa L.), sesame (Sesamum indicum L.) and tomato (Lycopersicon esculentum Mill.). The experiments were conducted in a BOD chamber located in the Laboratory of Plant Ecology (12h light: 12h dark, at 25 °C), with a total duration of …

The Impacts of Climate Change on Rice Production and Small Farmers' Adaptation: A Case of Guyana
… change is having an overall negative impact on rice production worldwide. The vast majority of climate change impacts on rice production result from fluctuations in precipitation and temperature, which lead to flooding, water scarcity, and increases in insects and pests, diseases, and weeds. As …

Identification of molecular markers and association mapping of selected loci associated with agronomic traits in rice
… markers associated with complex traits in US rice germplasm. Markers for percent head rice, percent total rice, and grain yield were identified with high levels of correct classification that mapped within or near traditional Quantitative Trait Loci (QTL). Mixed model-regression procedure to …

MODELLING THE INTERACTION BETWEEN WILD AND CULTIVATED SPECIES.
… cropping systems worldwide, e.g., in the case of rice weeds they can reach 60%. However, in the broader sense, wild species may also have positive effects on cropping systems for their capability to provide environmental benefits. In fact, they are fundamental to maintain high levels of …
