Standard Practices for Pesticide Applicators Standard Practices for Pesticide Applicators 10/09 Printed in Canada BK35 About WorkSafeBC WorkSafeBC (the Workers’ Compensation Board) is an independent provincial statutory agency governed by a Board of Directors. It is funded by insurance premiums paid by registered employers and by investment returns. In administering the Workers Compensation Act, WorkSafeBC remains separate and distinct from government; however, it is accountable to the public through government in its role of protecting and maintaining the overall well-being of the workers’ compensation system. WorkSafeBC was born out of a compromise between B.C.’s workers and employers in 1917 where workers gave up the right to sue their employers or fellow workers for injuries on the job in return for a no-fault insurance program fully paid for by employers. WorkSafeBC is committed to a safe and healthy workplace, and to providing return-to-work rehabilitation and legislated compensation benefits to workers injured as a result of their employment. WorkSafeBC Prevention Information Line The WorkSafeBC Prevention Information Line can answer your questions about workplace health and safety, worker and employer responsibilities, and reporting a workplace accident or incident. The Prevention Information Line accepts anonymous calls. Phone 604 276-3100 in the Lower Mainland, or call 1 888 621-7233 (621-SAFE) toll-free in British Columbia.

  • Alternative Herbicides in Turfgrass and Organic Agriculture
    1 Volume XXXII, Number 5/6, May/June 2010 Alternative Herbicides in Turfgrass and Organic Agriculture By William Quarles Photo courtesy of Marrone Bio Innovations number of alternative herbi- cides have been developed A and are now either commer- cially available, or waiting for EPA approval. Major markets for these herbicides include the turfgrass industry and organic agriculture. Demand for “green” herbicides in turfgrass is being driven both by environmental concerns and regula- tory action. For instance, a number of provinces in Canada have banned cosmetic application of chemical pesticides such as 2,4-D for broadleaf weed control on lawns. Cultural methods can relieve some weed pressures, but alternative herbicides can make weed manage- ment less labor intensive (Abu- Dieyeh and Watson 2009; Hashman 2011; Bailey et al. 2010; Boyetchko et al. 2009).

  • OGC Revisions Final Draft IPM Guidelines 4 19 21
    EAST BAY MUNICIPAL UTILITY DISTRICT INTEGRATED PEST MANAGEMENT PROGRAM GUIDELINES April 2021 INTRODUCTION The East Bay Municipal Utility District (District) is responsible for implementing pest control management practices across approximately 57,000 acres of watershed lands and reservoirs in the East Bay and Sierra foothills. This includes multiple recreation areas, over 100 miles of rights-of-way along our aqueducts, facility grounds at hundreds of sites in five counties and other areas located throughout the District’s water source and service areas. Pests may include a wide range of both plant and animal species capable of creating a nuisance; however, the predominant pest addressed by the District is invasive vegetation. Within the District’s footprint, pests are managed for a number of reasons including but not limited to human health and safety, protection of infrastructure, regulatory requirements, fire risk reduction and preservation of habitat and biodiversity. The District is committed to using the most environmentally safe practices for pest control to ensure the health and safety of the public and District employees, and to protect potable water quality, natural resources and public and private property. The District established an Integrated Pest Management (IPM) program in the 1990s to develop a consistent approach toward pest management throughout the District using a combination of physical, biological and cultural controls and includes the use and monitoring of pesticides, which predominantly consist of herbicides. The IPM program provides written guidance for determining the most appropriate pest control methods for a particular situation. Ever evolving IPM procedures and practices are developed with input from industry and academic experts and staff having pest management responsibilities to ensure they are implementable and effective.

    UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON D.C., 20460 OFFICE OF PREVENTION, PESTICIDES AND TOXIC SUBSTANCES MEMORANDUM DATE: July 31, 2006 SUBJECT: Finalization of Interim Reregistration Eligibility Decisions (IREDs) and Interim Tolerance Reassessment and Risk Management Decisions (TREDs) for the Organophosphate Pesticides, and Completion of the Tolerance Reassessment and Reregistration Eligibility Process for the Organophosphate Pesticides FROM: Debra Edwards, Director Special Review and Reregistration Division Office of Pesticide Programs TO: Jim Jones, Director Office of Pesticide Programs As you know, EPA has completed its assessment of the cumulative risks from the organophosphate (OP) class of pesticides as required by the Food Quality Protection Act of 1996. In addition, the individual OPs have also been subject to review through the individual- chemical review process. The Agency’s review of individual OPs has resulted in the issuance of Interim Reregistration Eligibility Decisions (IREDs) for 22 OPs, interim Tolerance Reassessment and Risk Management Decisions (TREDs) for 8 OPs, and a Reregistration Eligibility Decision (RED) for one OP, malathion.1 These 31 OPs are listed in Appendix A. EPA has concluded, after completing its assessment of the cumulative risks associated with exposures to all of the OPs, that: (1) the pesticides covered by the IREDs that were pending the results of the OP cumulative assessment (listed in Attachment A) are indeed eligible for reregistration; and 1 Malathion is included in the OP cumulative assessment. However, the Agency has issued a RED for malathion, rather than an IRED, because the decision was signed on the same day as the completion of the OP cumulative assessment.

  • Comprehensive LC/MS/MS Workflow of Pesticide Residues in High Water
    Application Note Food Testing and Agriculture Comprehensive LC/MS/MS Workflow of Pesticide Residues in Food Using the Agilent 6470 Triple Quadrupole LC/MS System Pesticides residue workflow in high water content, high oil content, and high starch content samples Authors Abstract Aimei Zou, Sashank Pillai, A comprehensive LC/MS/MS workflow was developed for the quantitation of Peter Kornas, 510 pesticide residues with the intention to accelerate and simplify routine Melanie Schober, Limian Zhao, laboratory food testing. Compound transitions and optimized parameters were Marco Zanotti, and developed based on the Agilent Pesticide Dynamic MRM Database, which has over Chee Sian Gan 750 pesticides including curated parameters for fast and easy transfer into the Agilent Technologies, Inc. analytical method. The workflow includes sample preparation, chromatographic separation, mass spectrometry (MS) detection, data analysis, and interpretation. The workflow applicability was demonstrated using an Agilent 1290 Infinity II LC system coupled to an Agilent 6470 triple quadrupole LC/MS on three food matrices with different content types: tomato (high water content), wheat (high starch content), and olive oil (high oil content). For sample preparation of the tomato and wheat samples, an Agilent QuEChERS kit was used with dSPE cleanup. Extraction was performed with the QuEChERS kit followed by Agilent Captiva EMR—Lipid cleanup for preparing olive oil samples. Workflow performance was evaluated and verified according to SANTE/12682/2019 based on limit of detection (LOD) and limit of quantitation (LOQ), calibration curve linearity, and recovery and precision using matrix‑matched calibration standards from 1 to 100 μg/L. Over 95% of analytes demonstrated linearity with R2 ≥0.99, with calibration curves plotted from LOQ to 50 or 100 μg/L.

Abstract: Biopesticides are natural, biologically occurring compounds that are used to control various agricultural pests infesting plants in forests, gardens, farmlands, etc. There are different types of biopesticides that have been developed from various sources. This paper underscores the utility of biocontrol agents composed of microorganisms including bacteria, cyanobacteria, and microalgae, plant-based compounds, and recently applied RNAi-based technology. These techniques are described and suggestions are made for their application in modern agricultural practices for managing crop yield losses due to pest infestation. Biopesticides have several advantages over their chemical counterparts and are expected to occupy a large share of the market in the coming period.

  • Cannabis Grow Facilities: Identification and Handling of Hazardous Wastes, a Problem for Environmental Health Departments Daniel Keenan, Maria Duazo
    Title: Cannabis Grow Facilities: Identification and Handling of Hazardous Wastes, a problem for Environmental Health Departments Daniel Keenan, Maria Duazo Abstract Every new industry has it’s false starts, failed business ventures, and competition from operators that skirt the regulations. Growing marijuana requires the use of pesticides, plant nutrients and plant growth modifiers/regulators. Cannabis Grow Facilities that go out of business, have catastrophic losses from fires or business that are set up outside of the regulatory framework will oftentimes abandon what is most likely hazardous waste when they vacate the premises. This has become a problem for health departments who are oftentimes left “holding the bag” and who find the need to efficiently identify all of the products/wastes that are abandoned in the wake of a business failure. The products/wastes left behind must by law be considered as hazardous waste until otherwise identified. This presentation will introduce a solution to the need for efficient identification of wastes found at a Cannabis Grow Facility. The solution is a qualitative chemical analysis scheme that employs wet chemistry using the commercially available HazCat Kit. This presentation will quickly demonstrate the use of the HazCat Kit on various Cannabis Grow Facility pesticides/nutrient solutions and their identification/hazard classification. Background For the past eighty years, a prohibition era type economy has molded how Marijuana is grown and harvested in the United States [1]. Now that legalization is slowly becoming a realization, many of the practices employed by marijuana growers are coming to light. The environmental impact of marijuana cultivation has suddenly come to the forefront and it is not a pretty picture [2].

A new environmental movement in occidental countries promoting an organic agriculture favours the rebirth of botanical pesticides. These products confer an efective alternative to chemical pesticides such as glyphosate. Among the biopesticides, the α-terthienyls found in the roots of Tagetes species, are powerful broad-spectrum pesticides.
