The research objective has been to evaluate the effect, unexplored yet, of a mixture of three active ingredients of the herbicide Lumax 537.5 SE: terbuthylazine (T), mesotrione (M), and S-metolachlor (S) on counts of soil microorganisms, structure of microbial communities, activity of soil enzymes as well as the growth and development of maize. The research was based on a pot experiment establi...

Blood-feeding arthropods are vectors of infectious diseases such as dengue, Zika, Chagas disease, and malaria [1], and vector control is essential to limiting disease spread. Because these arthropods ingest very large amounts of blood, a protein-rich meal, huge amounts of amino acids are produced during digestion. Previous work on Rhodnius prolixus, a vector of Chagas disease, showed that, amon...

The aim of this study was to monitor the sediment, soil and surface water contamination with selected popular triketone herbicides (mesotrione (MES) and sulcotrione(SUL)), atrazine (ATR) classified as a possible carcinogen and endocrine disrupting chemical, as well as their degradation products, in Silesia (Poland). Seventeen sediment samples, 24 soil samples, and 64 surface water samples colle...

A ampliação do gergelim (Sesamum indicum) no Brasil é dificultada por problemas relacionados ao manejo de plantas daninhas. Assim, o objetivo foi avaliar a seletividade herbicidas aplicados em pós-emergência gergelim, bem como resposta produtiva da cultura controle das Primeiramente, avaliou-se comportamento para diferentes herbicidas. Na sequência, submetida doses herbicida maior (sethoxydim)....

Particle drift happens during herbicide application when droplets travel outside the intended site. Different nozzles produce various range of droplets, so they play a very important role in coverage and occasions. When small potential for off-target movement is high. Another factor determining particle distance between crops. Wind velocity gives energy to particles move away from target place....

S Studies evaluating the effectiveness of herbicides on weed control, coupled with sustainability management system, are great importance. The present study aims to evaluate efficacy post-emergence applied maize while inferring treatments employing an ecological approach. experiment was installed in a randomized block design four replications. consisted application atrazine at dose 1500 g ha-1;...
