3 HARDI nozzle supremacy Precise, dependable and accountable HARDI has produced sprayers since 1 - meeting the needs of all farmers and crops worldwide - a key goal that has demanded the world s best nozzles. Today the same basic HARDI philosophy promotes the efficient, effective and responsible plant care that ensures quality food production. The nozzle can dominate the sprayer performance. All of the sprayer components are important for safe and effective use, but it is the nozzle that can have the major influence on the performance of the plant protecting product that it will apply. HARDI quality nozzle production in Nørre Alslev, Denmark HARDI 's modern production facilities and technical abilities have resulted in the superior precision and durability of HARDI nozzles. The nozzle controls: The throughput [and therefore the dose] Quality of distribution Drop spectrum and coverage Distribution over the target Drop retention or reflection The degree of drift and downwind fallout Quality control includes not just laboratory measurements but the use of HARDI nozzles in the field, under commercial conditions. Every drop of spray needs to be both accounted for - and documented - in order to ensure the quality of food delivered onto the dining table, and it meets the demands of the public today. HARDI quality nozzles meet these increasing demands with world leading research and development. All these functions are considered by HARDI to ensure that the spray liquid is deposited exactly where it is needed, in its most effective form, and is not wasted. HARDI has combined both design and material selection to produce a range of nozzles that suit the broad demands of both crops and the vast array of agrochemical products available today. This has been the basis for HARDI s worldwide success. lose co-operation between farmers, advisers, chemical companies, independent and regulatory bodies with HARDI s agronomists has been the backbone of this continuing success. Quality in production ensures optimal field performance. The application of plant protection products to crops involves issues now, which go beyond traditional considerations such as economy and efficiency. Now nozzle choice and performance also relates to broad issues of drift such as airborne losses, downwind fallout and deposits on non-target surfaces within the treated area itself. All of these issues need to be carefully considered. HARDI is a world leader in understanding the concept of spray accountability and it is this knowledge that underpins its world leadership in today's spraying. Today, HARDI has developed the world s largest ISO nozzle programs for agriculture, horticulture [including most vegetables], viticulture as well as many more specialist needs. This nozzle guide will help you select the best nozzle for your needs, consider environmental aspects, and help you calibrate it for optimal use to ensure that you meet all of today s needs when using crop protection products.

4 Nozzle technology undamental research with nozzles by HARDI agro-scientists is conducted in their own dedicated laboratories and those of independent research centers at many key institutions throughout the world. Sites where field research is conducted are very diverse - ranging from the temperate conditions of Northern Europe to the tropical crops of Australia. Instrumentation used in HARDI s laboratories is at the leading edge in droplet size analysis studies. It is this broad, but intensive, approach combined with state of the art manufacturing techniques and computerized quality control programs, that guarantees HARDI nozzles will meet the demands of better crop protection. easuring droplet sizes The droplet spectrum is characterized by the average droplet size based on volume (VD) and the range that indicates the uniformity of the atomization. A laser Phase Doppler Particle Analyser (Aerometrics, PDPA) supplies this information instantaneously and is used to constantly monitor the spray quality of our nozzles in our laboratory.

5 Nozzle technology Nozzle development hanges in cropping practices, regulatory restraints and the introduction of new agrochemicals are just some of the forces that ensure new nozzle developments, which have and will continue to take place at HARDI. This activity closely involves our agronomists, engineers and specialist tool makers. armer's needs are recognized and met with HARDI nozzles designed to provide the precision they demand today. Wind Tunnel Studies Quality control Samples of all HARDI nozzles are constantly monitored by Quality ontrol - using devices such as this state of the art nozzle distribution table. Airborne drift and downwind fallout are tested and documented in the controlled conditions of a wind tunnel for all HARDI nozzles. This leads to approvals as drift reducing equipment for buffer zones in many countries. Together with field research this has given the HARDI nozzle range approvals in the UK, Holland and Germany to be used closer to waterways than previously allowed with traditional nozzles. High Speed Video odern high-speed video techniques are used to investigate the droplets behaviour on their way to the target and when impacting on a leaf. These tests are done with clean water and with actives to simulate in-field spraying. High Quality aterials HARDI nozzles are produced from high quality SYNTAL plastic that ensures both precision and durability. Where highly abrasive compounds are to be sprayed, the selection of HARDI ERAI nozzles will maintain this same level of superior durability. Deposit tests luorescent UV dye is used to test the exact amount of liquid that stays on the leaf after spraying. This is the key factor for the biological efficacy of the plant protection products Brass Stainless steel SYNTAL Durability relative to brass flat spray nozzle at the manufacturer s recommended pressure (Kim Sintorn, Swedish University). Efficacy trials Specialist field equipment is used at the Danish Weed Research Institute to test the efficacy of herbicide performance when using HARDI nozzles.

6 ie ld sp r a y i n g hoosing nozzles for arable crops A nozzle for every spray job hoosing nozzles hoice of nozzle type and size may have to balance the need to ensure optimal biological effect with a consideration for wind drift, sprayer capacity that influences field work rates as well as forward speed. The tables below can be used when choosing the right nozzle for a spray job. Important precondition for the tables: Always follow label recommendation for spray quality and volume rate if nothing is stated the tables can be used as a guideline. To minimize wind drift and maintain even liquid distribution, spraying pressure between to is recommended (INJET: to 1 ). Higher pressures with TWIN air assistance are also acceptable. Spraying against grass weeds or on other vertical targets it is important to use a relative fine spray LowDrift INJET Drift reduction / Spraying capacity The reduced number of very small droplets produced by LowDrift nozzles makes them less sensitive to wind. Therefore they can be used on conventional sprayers under sub-optimal conditions. In particular, they are used when spraying lower water volumes. INIDRIT and INJET nozzles mix air with the spray liquid to coarsen the atomization. Drift is substantially reduced with these nozzles so that field delays due to high wind speeds are minimized and timing is improved. The biological advantage gained through this better field timing may mask the use of coarser sprays. Their use has become critical to conventional spraying practice which has to try and meet both environmental needs without risking the effectiveness of the product to be applied. oarse edium ine 0 microns Standard Very oarse 0 microns TWIN 0 microns Bilological efficiency Growth stage eekes Decimal (Zadox) ine droplets = improved coverage Drift/Biological efficiency index microns Small droplets from STANDARD lat an nozzles may offer an unsurpassed liquid distribution and an effective coverage of the target surface. HARDI TWIN sprayers can safely use these Water volumes GPA small standard 1 nozzles even GPA - 1 GPA when weather GPA GPA conditions are 2 GPA not optimal. 2 GPA Small dicot weeds need good coverage either through fine droplets or if using a coarser spray by compensating with a higher volume rate. or large dicot weeds coarse atomization can be used. ungicide treatments are often less sensitive to spray quality; medium drops can be recommended. Remember that the volume rate must be adjusted to crop density and needs for penetration to more basal parts. Generally the water rate for conventional spraying should not be less than 1 GPA and for TWIN not less than.. GPA for optimum efficacy at lower doses. When mixing products or using products with more than one mode of action adjust to the most demanding component of that product mix.

7 i eld s pra y i n g HARDI nozzles on all liquid systems HARDI ISO nozzles fulfill ISO (International Standards Organization) standards regarding flow, numbers, colors and outer dimensions. This ensures that it is easy to fit HARDI ISO nozzles on all sprayer brands. You can see the fittings below, which allow you to adapt HARDI ISO nozzles to your sprayer. On sprayers with HARDI SNAP-IT systems, the HARDI OLOR TIPS (T) are recommended for safe and easy handling. or INJET nozzles use the 333 black nozzle cap. HARDI part 4233 Nitril O-ring for HARDI nozzles (Between ap and Nozzle Body ). On sprayers with TeeJet or compatible systems, use Single nozzles (S) and the 3342 black cap. The same cap is used for INJET nozzles. (gasket: ). On all other systems, use the ISO cap delivered with your sprayer together with Single nozzles (S) or INJET s (INJET s require a special 0.4" cap). onversion table for old HARDI 41 and HARDI ISO nozzles l/min 1.4 GP lows at pressure from to (1. to bar) bar HARDI HARDI ISO bar You can use these figures to check the new HARDI ISO nozzles that may replace your old 41 nozzles.

8 ie ld sp r a y i n g alibration of field crop sprayers Precise and safe applications in the field demand that the sprayer is effectively calibrated. alibration must always be done with clean water and before the use of any crop protection product. ollow these three steps to calibrate your sprayer. 2 Select volume rate, nozzle and pressure 1 heck driving speed Half fill the spray tank with water. or easy selection of nozzles and pressure, use the HARDI calibration disk (order no US or metric).

Dirty and/ or blocked nozzles are the most frequently reported problem affecting distribution. leaning nozzles is best done using water and a soft brush such as a toothbrush. Never use tools like screwdrivers or nails - they will certainly damage the nozzle and its ability to evenly distribute the sprayed liquid. A soft brush for nozzle cleaning is included as a part of the HARDI calibration set (1243). When did you last check the output from your nozzles? Liquid fertilizer Liquid fertilizers may be of a higher liquid density than water and almost all, normal spray solutions. The density correction table below states the increased pressure that will be needed to reach the required output with such liquids. Example The nozzle has an output of 0. GP at. If the density of the liquid fertilizer is. lbs/gal you have to multiply the calibration pressure found when checking the nozzle flow with water with the density factor. This gives an adjusted pressure of 4. The value can be found in the table at (calibrated pressure) and a density of. lbs/gal.

The HARDI 13 cone nozzle can also be used without swirl plates for solid stream application (see page 1) Drop sizes The difference between the 4 swirl plates is the droplet size. The blue swirl plate has a very fine (V) droplet spectrum, the grey a fine () droplet spectrum and the black swirl plate has a medium () droplet spectrum. The white swirl plate has a medium () droplet spectrum and is giving a full cone spray. Large drop adaptor A large drop adaptor (3) is available for the grey swirl plate. This adaptor changes the droplet spectrum to very large (VL) droplets No Box of pcs pc GP pcs pcs GP pcs GP pcs Drop Nozzle: GP pcs pcs. 1 3 pcs pcs. 1 1

22 Ba nd sp r a y i n g Band spraying In many crops, band spraying provides an efficient way of reducing chemical consumption. HARDI produces both conventional and air assisted special sprayers for row crops. ALIBRATION OR BAND SPRAYING 1 orward speed See page alibration of field sprayers Row spacing 2 GPA in band Label recommendations usually state total GPA rates, also called broadcast rates. When band spraying we only want to apply this broadcast rate in the bands, so instead we will here call it: GPA in band. 3 alculation of nozzle capacity GPA in band x band width (inch) x PH Band width If the row spacing is "; band width "; field acres; and GPA in band = GPA the total required volume will be: x x = GP per band If GPA is to be applied at 3 PH in a " wide band, the necessary output will be: 0.1 GP/per band. If, for instance, 1 nozzle per band is used, every nozzle should apply 0.1 GP. Nozzles and pressures can then be found in the relevant tables. 4 alculation of total required volume of spray mix area of field (acre) x GP in band x band width (inch) = spray mix (total gal/field) row spacing (inch) =. gallons alculation of chemical per tank gallons of water in tank x chemical dose desired (GPA) = gallons of chemical per tank GPA in band If the tank holds 0 gallons and 2 gallons of chemical products are required per acre when GPA in band is applied, the following calculation should be used: 0 x 2 = gallons of chemical product per tank Even spray nozzle HARDI 40E 0 Even spray nozzle SYNTAL. Even distribution is ideal for band spraying Use the 40E on hand operated sprayers, when only one nozzle is used Application range: 0.0 to 1.44 GP Pressure range Because of the even spray distribution from this nozzle, it is especially well suited for row and inter-row spraying. It is used on hand operated sprayers or on a spray boom where chemicals need to be applied over a narrow area. 40E -E E -E -13E -1E -21E -2E -2E 0-3E GP The spray width can be changed by angling the nozzle
