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...

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...

Farmers' participatory field trials were conducted at Madhuban, and Taraori, the two participatory experimental sites/locations of the Cereal Systems Initiative for South Asia (CSISA), a collaborative project of IRRI and CIMMYT in Karnal district of Haryana, India, during Kharif (wet season) 2010 and 2011. This research aimed to evaluate preemergence (PRE) and postemergence (POST) herbicides fo...

Experiments were conducted during the summer of 2002 at the Rice Research and Extension Center, Stuttgart, AR, to evaluate: 1) various timings of sequential applications of imazethapyr at 0.063 lb/acre (4 oz Newpath/acre) in conventional and staleseedbed rice planting systems utilizing Clearfield ‘CL-161’ and 2) the timing of clomazone application at various rates and timings in conventional ri...

Fourteen pesticides (fungicides, herbicides, and insecticides) were tested to determine whether they had deleterious effects on the bioinsecticide Bacillus popilliae, the causal agent of milky disease. All of these pesticides reduced levels of spore viability, spore germination, and/or vegetative cell growth when they were tested over a range of concentrations from 0 to 1,000 ppm of active ingr...

Runoff from farm fields is a common source of herbicide residues in surface waters. Incorporation by irrigation has the potential to reduce herbicide runoff risks. To assess impacts, rainfall was simulated on plots located in a peanut (Arachis hypogaea L.) field in Georgia's Atlantic Coastal Plain region after pre-emergence application of metolachlor (2-chloro-N-(2-ethyl-6-methylphenyl)-N-[(1S)...

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...

A field study on the effects of pre- and post-emergence application herbicide (pendimethalin) reproductive yield five accessions cowpea (TVu-9092, TVu-16265, TVu-16320, TVu-16323 TVu-16421) was conducted between June August, 2018. Pendimethalin applied both as early (PE EPOE) followed by hand weeding at 4 8 weeks after sowing (WAS). Number pods per plant highest in TVu-9092 treated with 0.125 k...

Abstract Crop residue can intercept and adsorb residual herbicides, leading to reduced efficacy. However, adsorption sometimes be reversed by rainfall or irrigation. Greenhouse experiments were conducted evaluate the effect of differential overhead irrigation level on barnyardgrass response acetochlor, pyroxasulfone, pendimethalin applied bare soil wheat straw–covered soil. Acetochlor resulted ...
