Cassava is grown on the floodplains of Solimões river and guarantees food security income for farmers. However, negative interference weeds can result in a significant yield loss crop. Therefore, aim this study was to evaluate selectivity herbicides efficiency chemical weed control cassava ‘Aipim-manteiga’ cultivar, floodplain river, Iranduba, Amazonas. The experimental design randomized blocks...

Ischaemum rugosum Salisb. (Saramolla grass) is a noxious weed of rice that is difficult to control by chemical or mechanical means once established. A study was conducted to determine the effect of light, temperature, salt, drought, flooding, rice residue mulch, burial depth, and pre-emergence herbicides on seed germination and emergence of I. rugosum. Germination was stimulated by light and in...

The study aimed to assess the occurrence and environmental risk of a group 51 selected pesticides in Guadiana Basin (a biodiversity hotspot, Mediterranean). most abundant were bentazone 2,4-D, while terbuthylazine together with terbutryn constituted ubiquitous pesticides. Eighteen out 38 detected are no longer approved Europe, 5 them included list priority substances. assessment showed that azi...

Pesticides have been used to control pests in agricultural fields and storage systems before circulating products markets. A tandem mass spectrometry, equipped with gas chromatographic separation (GC–MS/MS) or ultra-performance liquid (LC–MS/MS), was monitor residual pesticides Korean rice paddy soils. Selective multiple reaction monitoring employed during the analyses achieve multiresidue pest...

O principal método de controle plantas daninhas na cultura do alho é o químico, contudo essa extremamente sensível à herbicidas, podendo sofrer injúrias e redução produtividade dependendo dos produtos utilizados, modalidade aplicação, dose, cultivar, dentre outros. Assim objetivo presente estudo foi avaliar a seletividade herbicidas para cultivar Chonan, aplicados em diferentes modalidades apli...

Abstract In the transition zone, turfgrass managers generally utilize dormancy period of warm-season to apply herbicides for managing winter annual weeds. Although this weed control strategy is common in bermudagrass, it has been less adopted zoysiagrass ( Zoysia spp.) due variable injury during post-dormancy transition. Previous research reported that air temperature could affect and crop safe...

Parthenium hysterophorus L. is a noxious alien invasive weed species rapidly spreading in Bangladesh. P. examined the prospects of using allelopathic extracts during period July 2021 to June 2022. Experiments were conducted net house at Sher-e-Bangla Agricultural University, non-cropped areas Khustia and cropped Chudanga.
