Journal of Bioresource Management

Pesticides are specially designed to control pests and help in increasing the yield of crops. This study aims to investigate the genotoxic effect of the major ingredients of commonly used pesticides (Profenophos and Cypermethrin) on Allium cepa L. in different regions of the province of Punjab, Pakistan. Profenophos and Cypermethrin pesticides are extensively used by local farmers. six different dilutions of Profenophos and Cypermethrin pesticide ranging from, 0.5 ml/L, 1 ml/L, 1.5 ml/L, 2 ml/L, 2.5 ml/L and 3.0 ml/L were applied initially on seeds germination. Seeds grown in a 3.0 ml/L concentration showed a lower radical length percentage as …

Root Phenotyping Of Peptide-Treated Glycine Max, Salem Jackson

Biological Sciences Undergraduate Honors Theses

Plant elicitor peptides (Peps) – endogenous chains of amino acids involved in natural plant defense – have been shown to decrease damage from herbivores and pathogens by inducing an immune response, increasing the emission of volatile organic compounds (VOCS), transcripts, and metabolites. Exogenous treatment of soybean seeds with plant elicitor peptide GmPep3 has been shown to induce these broad-spectrum defenses and offers a new method for increasing crop yield. However, the effects of GmPep3 on indicators of soybean health – root characteristics, growth stages, etc. – have not been fully realized.

Using the root-phenotyping platform RhizoVision Explorer, several root traits …

Presence Of Pesticide Residue In Feeds–An Assessment, Arpana Singh, S. K. Nag

IGC Proceedings (1997-2023)

The presence of varying types of toxic substances in feed is undesirable as it acts as the main source of entry of these chemicals into the animal body, redistribution and deposition in different tissues for a long time depending on the nature of the toxicants. Feed safety is equally important as food safety as both are directly linked when production of food of animal origin is concerned. Presence of pesticide residues are often reported in different feed resources (Kang et al., 2002; Sharma et al., 2005; Nag, 2006). These residues may ultimately contaminate the food chain and accumulate in human …

Modeling Effects Of Ecological Factors On Evolution Of Polygenic Pesticide Resistance, C. V. Haridas, Brigitte Tenhumberg

School of Biological Sciences: Faculty Publications

Widespread use of pesticides has resulted in the evolution of resistance in many insect pests worldwide, limiting their use in pest control. Effective pest and resistance management practices require understanding of the genetics of resistance and the life history of the pest. Most models for pesticide resistance assume that resistance is monogenic, conferred by a single gene. However, resistance could evolve as a polygenic quantitative trait resulting from the action of several genes, especially when pesticide dose is low. Further, fitness of the pest could be density dependent and might depend upon abiotic factors such as temperature. It is not …

Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hull Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman

The Kennesaw Journal of Undergraduate Research

The Chattahoochee Nature Center (CNC) is one of the leading educational centers in Georgia about the ecology of the Chattahoochee River. Due to lack of man power, keeping down the weeds in the CNC plant nursery is one of those tasks that often gets left undone. The nursery becomes overgrown with invasive weed species. Understandably, they must sometimes resort to the use of herbicides, such as Roundup®, to keep the hundreds of native and endangered species of plants housed at CNC from being choked out by invasive weeds. This study tests the ability to suppress weed growth by use of …

Nozzle Sensor For In-System Chemical Concentration Monitoring, Joseph S. Dvorak, Timothy S. Stombaugh, Yongbo Wan

Biosystems and Agricultural Engineering Faculty Publications

Chemical concentration is a vital parameter for determining appropriate chemical application. This study describes the design and testing of a sensor that attempted to monitor concentration of chemicals upstream from each nozzle body. The sensor is based on an LED and photodiode pair. Its ability to detect chemical concentration within the main carrier was tested with a 2,4-D formulation, a glyphosate formulation, and a powdered Acid Blue 9 dye. The liquid herbicide formulations of glyphosate and 2,4-D were tested across common application concentrations of 0% to 12.5% by volume. The powdered dye produced a much stronger effect on the sensor …

Interactions Among Insect Defoliation, Insecticide Treatments, And Growth Rate In American And Hybrid Chestnuts, Ashley Elizabeth Case

Masters Theses

The American chestnut, Castanea dentata, was once one of the most useful and abundant canopy trees in eastern North American forests. Over the last 200 years, the species has been decimated by two exotic pathogens, Phytophthora cinnamomi and Cryphonectria parasitica, killing millions of trees and reducing surviving Castanea dentata to short-lived sprouts. Cryphonectria parasitica-resistance breeding programs are currently producing advanced backcross generations, which are being compared with pure American chestnut in field tests of growth performance and Cryphonectria parasitica resistance. The Asiatic oak weevil, Cyrtepistomus castaneus, has been identified as a common defoliator of chestnut seedlings in these …

W213 Sencor™ Tolerance Ratings For Selected Wheat Varieties, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Bluegrass (aka Poa) and broadleaf winter annuals like henbit have caused serious yield loss in some wheat fields the last several years. In cases where these weeds were a problem, they became established before or with the wheat. If Poa or henbit becomes established with the wheat, it can deter tillering and readily compete for nitrogen. One way to manage these weeds is to apply Sencor at 3 to 4 oz/a postemergence over the wheat that is at 2 to 41f. This timing of a Sencor application has been a very inexpensive way to manage bluegrass and broadleaf weeds like …

Sorption-Desorption Of Imidacloprid And Its Metabolites In Soil And Vadose Zone Materials, Sharon V. Papiernik, William C. Koskinen, Lucia Cox, Pamela J. Rice, Sharon A. Clay, Nancy R. Werdin-Pfisterer, Kristen A. Norberg

Agronomy, Horticulture and Plant Science Faculty Publications

Sorption-desorption is one of the most important processes affecting the leaching of pesticides through soil because it controls the amount of pesticide available for transport. Subsurface soil properties can significantly affect pesticide transport and the potential for groundwater contamination. This research characterized the sorption-desorption of imidacloprid (1-[(6-chloro-3-pyridinyl)-methyl]-Nnitro-2-imidazolidinimine) and three of its metabolites, 1-[(6-chloro-3-pyridinyl)methyl]-2-imidazolidinone (imidacloprid-urea), 1-[(6-chloro-3-pyridinyl)methyl]-4,5-dihydro-1H-imidazol-2-amine (imidaclopridguanidine), and 1-[(6-chloro-3-pyridinyl)methyl]-1H-imidazol-2-amine (imidacloprid-guanidine-olefin), as a function of changing soil properties with depth in two profiles extending from the surface to a depth of 1.8 or 8 m. Sorption of each compound was highly variable and hysteretic in all cases. Normalizing the sorption coefficients (Kf) …

Pb1595-Using Pesticides In Greenhouses, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The objective of using pesticides in greenhouses is to reduce or manage pest populations without endangering the lives of greenhouse workers or customers, and without harming plants. To achieve this goal, it is essential to maximize pesticide exposure to the targeted pests and minimize human pesticide exposure. The first part of this publication will address issues related to pesticide applications, whereas the second part addresses human safety issues.
