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...

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...

Context Yield losses in lentil (Lens culinaris ssp. Medik.) caused by weeds are estimated at 20–80%. In the absence of effective broad-spectrum herbicides, menace weed has emerged as a serious yield constraint lentil. Aims Identification tolerance to two post-emergence imazethapyr and metribuzin. Methods 221 accessions were screened experimental research station International Center for Agricul...

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)...

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...
