SUPPRESSION OF Urochloa brizantha AND U. ruziziensis BY GLYPHOSATE UNDERDOSES [PDF]

Revista Caatinga, 2019
ABSTRACT Intercropping of Urochloa species with corn is an alternative to enable the no-tillage system, besides influencing weed community. Therefore, the investigation of underdoses of the herbicide glyphosate to manage grasses in intercropping systems, avoid grain yield losses, and make feasible intercropping in agricultural areas is important.

Molecular and Structural Characterization of Foam Proteins from Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) Nymphs Reveals Adaptive Features and Potential Targets for Pest Control. [PDF]

Arch Insect Biochem Physiol
Nymphs of Mahanarva spectabilis produce a protective foam that supports survival, reduces plant damage, and contributes to adult population establishment. Proteomic profiling combined with protein sequencing and structural modeling revealed foam proteins enriched in functional domains associated with environmental resilience.

Leaf anatomy of Urochloa brizantha and Urochloa ruziziensis (Poaceae) plants subjected to different fertilization management practices

Agronomy Science and Biotechnology, 2022
Brazilian agribusiness is heavily influenced by beef export. Thus, it is important to evaluate the quality and growth rate of forage species used as cattle food. Given that the structural organization of leaf cells and tissues is directly related to forage-plant growth, we aimed to analyze the foliar anatomy of Urochloa brizantha and U.
