| Spraying The Importance of sprayer testing Everyone will agree that accurate application of pesticides is not only desirable but essential whether for the environment, the consumer or the grower. ccurate and targeted use of pesticides is all part of modern agriculture. That why back in the mid 90’s the Chemical Application members of the Agricultural Engineers Association (AEA) devised a test for application machinery to make sure it was working as intended and with a qualified operator would apply pesticides accurately and on target. In the early years of 2000 this test became the National Sprayer Testing Scheme as one of the main pillars of the Voluntary Initiative. NSTS now tests around 16,500 machines annually and this test also satisfies the requirements of the Sustainable Use Directive (SUD), which requires that all pesticide application equipment, sprayers, slug pellet applicators, granular applicators etc., need to be tested by 26th November 2016 and at regular intervals thereafter. NSTS is an accepted part of arable agriculture and requirement of the major crop assurance A schemes and supermarket protocols, requiring that farmers and growers have their sprayers inspected annually. This requirement will continue and one of the annual tests will satisfy the SUD requirements. The NSTS is available through a network of test centres who have qualified examiners available to inspect and confirm the equipment is of the standard required. The test is usually carried out at the machine owner’s premises and at a mutually agreed convenient time. The examiner will charge for the inspection, NSTS have no input into the cost of individual tests; the cost is commercial at the point of use. Additionally machine owners are free to use their nearest or preferred test centre. The operator or owner of the machine can prepare the sprayer for the test using a test sheet available from the NSTS website. Owners and operators are encouraged to be present during the test and will receive three NRoSO points for doing so. As confirmation of the result of the test the examiner will apply a pass sticker to the machine and give the owner a copy of the test report form. Other copies of the form are returned to NSTS Administration where the information is retained on a database of all tested machines. This information is available to Crop Assurance Certification Bodies for verification. With the continued threat of more pesticides being lost, now is the time to contribute to accurate and targeted application procedures, NSTS testing helps achieve that. Having a NSTS will also satisfy the Sustainable Use Directive which requires all sprayers to be tested by 26th November 2016.

You are entirely focused on harvest then, before you know it, you are back on the sprayer seemingly playing catch-up, applying pest and weed control programs and hoping the sprayer is in good fettle for the upcoming season. But, taking time to look back over last year’s spray program, was there anything you would do differently or better? Looking at water rates, are you ‘eking out’ a tank full to cover a certain area of land or are you taking a more proactive approach to ensure that an expensive chemical does the best job it can for you? AHDB York monitor farmer David Blacker has taken the latter course of action and raised water rates 280lt/ha for all soil-acting preemergence herbicide applications and applying it through fore and aft facing
