The Role of Triplet State Keto–Enol Tautomerism in the Photodeamination of Metamitron

The Journal of Physical Chemistry A, 2011
Substituted 4-amino-1,2,4-triazin-5-ones undergo photodeamination through cleavage of the N-NH(2) bond in the presence of oxygen and water. To elucidate the mechanism of this reaction, we investigated the photolysis of metamitron (4-amino-6-phenyl-3-methyl-1,2,4-triazin-5-one) by nanosecond laser flash photolysis, steady-state irradiation, and ab ...

Taxa fotossintética em macieiras tratadas com metamitron [PDF]

Revista Eletrônica Científica da UERGS, 2017
Metamitron (MM) um herbicida que inibe a fotossíntese, foi, recentemente, relatado como efetivo para raleio de pós floração em macieira, porem pouco se sabe sobre o seu período de interferência sobre a taxa fotossintética e possíveis interferências no desenvolvimento dos frutos após sua aplicação.

Effects of anthropogenic stress on hosts and their microbiomes: Treated wastewater alters performance and gut microbiome of a key detritivore (Asellus aquaticus). [PDF]

Evol Appl, 2023
Abstract Human activity is a major driver of ecological and evolutionary change in wild populations and can have diverse effects on eukaryotic organisms as well as on environmental and host‐associated microbial communities. Although host–microbiome interactions can be a major determinant of host fitness, few studies consider the joint responses of ...

Temperature and soil moisture change microbial allocation of pesticide‐derived carbon

European Journal of Soil Science, Volume 74, Issue 5, September–October 2023., 2023
Changing environmental conditions alter the MCPA degradation dynamics and the allocation of pesticide‐derived carbon to anabolic or catabolic metabolism. Abstract Temperature and soil moisture are known to control pesticide mineralization. Half‐life times (DT50$$ {DT}_{50} $$) derived from pesticide mineralization curves generally indicate longer ...
