Tujuan dilakukannya penelitian ini adalah untuk mengetahui efektivitas dari pencampuran herbisida dengan bahan aktif diuron dan hexazinon dalam mengendalikan gulma serta sifat campuran kedua tersebut. Penelitian dilakukan di rumah plastik Kecamatan Natar, Kabupaten Lampung Selatan bulan Mei hingga Juli 2022. disusun Rancangan Acak Lengkap (RAL). Perlakuan terdiri tiga jenis enam tingkat dosis a...

The decomposition of seven herbicides (atrazine, linuron, lenacil, chloridazon, dinoseb acetate, prometryn, and diuron) was carried out by detonative combustion. investigated blasting material produced on the basis porous ammonium nitrate, which served as an oxidizer, while pesticides played role fuel. Detonative mixtures in blast-holes soil. efficiency process assessed using techniques gas chr...

Stormwater from urban areas can transport biocidally active substances and related transformation products buildings into the environment. The occurrence of these in runoff depends on availability water, ultraviolet radiation exposure that causes photolytic reactions. In a systematic laboratory study, painted test specimens were exposed to either radiation, water contact, or combination both. L...

A 2-year study was implemented to characterize the contamination of estuarine continuums in the Bay of Vilaine area (NW Atlantic Coast, Southern Brittany, France) by 30 pesticide and biocide active substances and metabolites. Among these, 11 triazines (ametryn, atrazine, desethylatrazine, desethylterbuthylazine, desisopropyl atrazine, Irgarol 1051, prometryn, propazine, simazine, terbuthylazine...

ABSTRACT The sesame crop has great economic potential due to the various possibilities of exploitation, however, there is a lack information about chemical control weeds in crop, mainly application herbicides pre-emergence. Therefore, objective this study was evaluate viability and efficacy applied pre-emergence for crop. experimental design randomized blocks, with four replications. treatments...

Biocide contamination of receiving waters is generally linked with agriculture. However, recent studies have shown that urban contributions should be also considered [1,2]. One of the suspected biocide sources in the urban environment is building paint. Biocides like diuron, irgarol, terbutryn, carbendazim, etc., are conventionally used in paint to control fungi, algae, bacteria and other micro...

Abstract The objective of this work was to evaluate the effectiveness and selectivity herbicides applied at preemergence melon (Cucumis melo) crop. experiments were carried out from 2017 2018, in a randomized complete block design, with four replicates, state Rio Grande do Norte, Brazil. treatments consisted application of: 35 g ha-1 a.i. flumioxazin, 25 250 sulfentrazone, 480 metribuzin, 240 o...

Pre-emergent herbicides are applied directly in the soil or over straw no-till systems and can be retained, reducing product’s availability. The current study characterizes retention of diclosulam diuron forage turnip (FT), buckwheat (BW), black oat (BO) straws. Radiometric techniques evaluated sorption–desorption leaching processes. Spectroscopic microscopic methods characterized chemical morp...

Results of nine post-emergence herbicide phytotoxicity experiments are reported. The experiments were conducted on medium to heavy soils at Pongola in the northern irrigated part of the industry or on light soils at Shakaskraal on the Natal north coast. Tests were conducted using the recommended rates of herbicide combinations and double these rates, applied directly over the sugarqane foliage ...
