Agrisearch Analytical



	Agrisearch Analytical offers the following testing services: Analysis of Samples From Supervised Residue Field Trials Herbicide Contamination of Soil, Water and Food Surveillance of Food for Pesticide Residues Notes on Sampling/Sub-Sampling Veterinary Drug Residues Routine and Accelerated Storage Tests on Agrochemical and Veterinary Health Products Method Development/Validation
	Analysis of Samples From Supervised Residue Field Trials All organisations registering agrochemicals need timely and accurate data that will satisfy the requirements of the Australian Pesticides and Veterinary Medicines Authority (APVMA) and other international regulatory agencies. The key to meeting deadlines for product registration is to utilise an experienced contract research organisation (CRO) for field and laboratory services. Our residue laboratory is equipped with the latest technology to ensure that crucial deadlines are met. State of the art equipment includes: LC/MS/MS (Liquid Chromatograph- Triple Quad) GC/MS/MS (Gas Chromatograph- Triple Quad GC/MS (Gas Chromatography/Mass Spectrometry) HPLC (High Pressure Liquid Chromatography) with Diode Array, UV/Visible and fluorescence detectors. Agrisearch Analytical is committed to keeping pace with developments in analytical chemistry and with changes in regulatory requirements to ensure that submissions to regulators do not strike unexpected barriers. Agrisearch Analytical is recognised by NATA to ISO/IEC 17025 for the analysis of pesticide residues and to conduct studies in compliance with the OECD Principles of Good Laboratory Practice. Agrisearch can offer door to door freezer transport of samples and guarantee sample integrity and a seamless integration of the field and analytical phases of GLP studies. By using Agrisearch Analytical and Agrisearch Services for your residue field trials you are assured of obtaining sound advice and the skills of an enthusiastic and dedicated analytical/research team committed to providing an expert service. Back to Top Herbicide Contamination of Soil, Water and Food When your crop is damaged by herbicide spray drift or carry-over from crop rotation it is difficult to identify the herbicide that has caused the damage. Due to the volatile nature of some herbicides such as 2,4-D, there is potential risk that vapour may drift off-target by up to 10 km. Positive identification and quantification of herbicide contamination in soil and plant material contributes to informed decision-making and to successful outcomes. Agrisearch Analytical has the latest analytical technology, skills and knowledge to identify and quantify the herbicide(s) causing crop damage. We provide the most comprehensive range of herbicide tests in Australasia. Our tests analyse soil, plant material and water for 50 of the most common herbicides that are currently in use in Australia to the lowest limits of detection. The range of herbicide tests include: Triazine, phenyl urea and other herbicides Phenoxy and phenoxypropionate herbicides Phosphonic herbicides (including glyphosate) Quarternary herbicides (including diquat & paraquat) Sulfonyl urea herbicides (including chlorsulfuron, metsulfuron and triasulfuron) For a list of herbicides included in each of the above tests and prices please contact Ross Shields or Susan McKeon.

	Surveillance of Food for Pesticide Residues There are approximately 500 pesticide molecules registered for use in Australia and New Zealand. Fruit and vegetable producers want to assure their market that residues are absent from their products or are below safe levels. The best way to achieve this is via ‘multi-pesticide residue testing’. Agrisearch Analytical has been at the forefront of developing multi-pesticide test methods since its inception in 2000. We were a foundation laboratory for the FreshTest ™ program, sponsored by the Australian Chamber of Fruit and Vegetable Industries and driven by leading supermarket chains, to provide quality assurance for produce sold at retail. We offer a reliable, cost effective and rapid service and our multi-pesticide residue tests are constantly updated to cover new pesticides as they emerge on the market. Agrisearch Analytical can offer a comprehensive range of multi-pesticide residue tests which can screen up to 200 pesticide residues at a time and reported to a level of 0.01mg/kg. We also offer a range of multi-herbicide tests that cover the major herbicide groups that are currently being sold in Australia and New Zealand. Back to Top
	Notes on Sampling/Sub-Sampling Any analytical data is only as good as the samples and/or sub-samples that were used to produce it. It is enormously important to ensure that samples submitted for analysis are "representative" of what you want to be tested. For example, it would not be a good idea to expect a single apple from a single tree at a single point in time to represent an entire season's production from a 100 hectare orchard. Some guidelines can be found on the APVMA web site, but they cannot cover every eventuality. In the above example it would be better to pick apples from several trees over the breadth of the orchard and if necessary sub-sample them down to a manageable quantity. Or it may be beneficial to split the sampling to represent smaller plots to get an idea of the uniformity of spraying. In cases where a crop is apparently adversely affected by herbicide, it is generally preferable to include a "control" of unaffected material. Care must be exercised in this case to avoid cross-contamination by picking the "control" sample first and by double-bagging all samples prior to transport. A maximum of a kilogram of produce is a good starting point when it comes to sample size. Much more and the time/cost involved in sample preparation and sub-sampling can become prohibitive. Having prepared one or more samples for submission it is then important that samples are labelled indelibly with sufficient information to fully identify them and to include sufficient "paperwork" (a "Sample Submission Form" is available for download from our "Links" page) to enable the laboratory to know from whom the samples came and what they are to be analysed for.

	Veterinary Drug Residues Agrisearch Analytical has proven excellence in the analysis of veterinary drugs either in bioequivalence or tissue depletion studies for the following classes of veterinary drugs: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Macrocyclic Lactones (Ivermecin, Moxidectin, Doramectin, Abamectin & Eprinomectin) b-Lactam Anti-biotics Closantel Levamisole Praziquantel, Pyrantel, Oxantel Cyromazine and Dicyclanil Back to Top
	Routine and Accelerated Storage Tests on Agrochemical and Veterinary Health Products Agrisearch Analytical has the facilities to conduct accelerated and long-term storage stability studies on your formulated products. We are able to conduct long term storage studies in controlled temperature and humidity cabinets according to company or international protocols. The products can then be tested for active content and physical characteristics as per the APVMA Guidelines for the Generation of Storage Stability of Agricultural Products. Can your product be successfully tank mixed with another product for efficient application? Agrisearch Analytical has experience in the assessment of formulation compatibility. The test data can then be collated in a report suitable for submission to the APVMA. Studies can be conducted according to the OECD Principles of GLP at either the Rozelle or the Orange sites.
