From semipermeable membrane devices (SPMDs) placed in five Mississippi Delta streams in 1996 and 1997, the persistent organic pollutants (POPs) aldrin, chlordane, DCPA, DDT, dieldrin, endrin, heptachlor, mirex, nonachlor, and toxaphene were detected. In addition, the insecticides chlorpyriphos, endosulfan, and hexachlorocyclohexanes were detected. Two low-solubility herbicides not detected comm...

A reduced herbicide rate with hand-weeding (HW) can act as a safer and sustainable approach for weed control. field study was conducted at CSIR-IHBT, Palampur, India during 2018 2019 to analyze the efficacy of herbicides in combination manual weeding on control yield wild marigold (Tagetes minuta L). The experiment laid 12 treatments, consisting two dosages prescribed rates (R) pendimethalin, i...

Herbicide resistance in weeds is a global threat to sustaining food security. In India, herbicide-resistant Phalaris minor was the major problem wheat for more than two decades, but continuous use of metsulfuron-methyl (an ALS inhibitor) control broadleaf has resulted evolution inhibitor-resistant Rumex dentatus L. This review summarizes current scenario herbicide R. dentatus, along with its ec...

Herbicides are usually applied multiple times by growers for season long weed control in Florida citrus (Citrus sp.). Rimsulfuron, a sulfonylurea herbicide has been recently registered for control of certain grasses and broadleaf weeds in citrus. To increase the weed control spectrum and reduce application cost, citrus growers often prefer to tank mix herbicides. Field experiments were conducte...

A field experiment with the objectives to understand evaluation of mulching effects on weed control in blackgram production under irrigated condition involving two factors viz., (paddy straw mulching, sugarcane trash no mulching) and herbicidal treatments (pendimethalin pre-emergence (PE) @ 1.0 Kg/ha, pendimathalin + Imazethapyr (pre-mix) Valor 32% EC Hand weeding 15 30 days after sowing, weedy...

Abstract Herbicide-resistant Palmer amaranth is a troublesome weed in several agronomic crops and relatively new challenge to dry bean production western Nebraska. Objectives were evaluate preemergence (PRE) postemergence (POST) herbicides for control of acetolactate synthase–resistant their effect on density biomass as well injury yield Field experiments conducted 2017 2019 near Scottsbluff, N...

Fertilizers and pesticides have been widely used in agriculture production, causing polluted soil, water, atmosphere. This study aims to quantify air emissions from fertilizers applied for peanut production Georgia during selected years (1991, 1999, 2004, 2013, 2018). Specifically, the oral dermal potential impacts pesticide global warming (GWP) impact were investigated. followed ISO 14040 seri...

The field experiments were conducted during two consecutive seasons of kharif (June to October), 2016 and 2017 at the Experimental Research Farm, ICAR Complex for NEH Region, Nagaland Centre, Medziphema, Nagaland, India. treatments consisted four planting geometries i.e. maize+black gram (1:1), (2:2), maize+soybean (1:1) (2:2) three weed management practices weedy check, pre-emergence applicati...

Finger millet (Elusine coracana) accounts for 8% of the total area and 11% production worldwide. It is grown on over 4 million ha globally, mainly food purposes. Millions people in dry lands Central East Africa, South India depend finger as an important source to them (CGIAR, 2001). one most neglected underutilized crops. Additionally, crop has received limited research attention compared wheat...
