Essential oils (EOs) are plant-derived aroma compounds with a wide range of biological activity, but their actions are slow, and they are typically unstable to light or heat, difficult to extract and so on. To find highly potential fungicides derived from natural EOs, a series of essential oil-based β-methoxyacrylate derivatives have been designed and synthesized. The target compounds have been...

Cerrado biodiversity has been threatened by the increase in agricultural production state of Tocantins and use pesticides. This work was carried out Formoso do Araguaia region, on banks River, which is home to about 1,825 indigenous people one largest lands Tocantins, Brazil. The presence pesticides imidazolinone strobirulin classes verified, analyzed UHPLC-MS/MS from April 2018 February 2019, ...

Sclerotinia stem rot (SSR), caused by sclerotiorum, is a devastating disease of oilseed rape that may cause significant yield losses if not controlled cultural management strategies and fungicide applications. Studies were conducted to evaluate the efficacy different group fungicides as well biopesticide, including azoxystrobin, boscalid, fludioxonil, prothioconazole, tebuconazole, azoxystrobin...

Abstract The most commonly used method to control wheat powdery mildew is by fungicides. aim of the present study determine duration fungicide activity three fungicides: azoxystrobin; triadimenol; tebuconazole+spiroxamine+triadimenol. They were applied in concentrations phenophase 3-4 leaf susceptible variety. After treatment, each day one pot tested was inoculated with Blumeria graminis f. sp....

This paper evaluates the effects of different time-varying exposure patterns of the strobilurin fungicide azoxystrobin on freshwater microsocosm communities. These exposure patterns included two treatments with a similar peak but different time-weighted average (TWA) concentrations, and two treatments with similar TWA but different peak concentrations. The experiment was carried out in outdoor ...

Yellow and black Sigatoka, caused by Mycosphaerella fijiensis M. musicola, respectively, are the most important worldwide foliar diseases of bananas. Disease control is heavily dependent on intensive fungicide sprays, which increase selection pressure for resistance in pathogen populations. The primary objective this study was to assess level spread quinone-outside inhibitors (QoI—strobilurin) ...
