GENERAL INSTRUCTIONS

Imtrade Diablo Duo Herbicide is a short residual, soil applied, pre-emergent herbicide that is absorbed by the roots and shoots (coleoptile) of germinating seedlings with inhibition of growth in the meristematic region. Upstream translocation in the plant occurs but movement in the phloem is very unlikely. Best activity can be expected from applications before or shortly after the germination of target weeds. Imtrade Diablo Duo Herbicide should be applied to a seedbed free of soil clods and emerged weeds. Product efficacy may be reduced by improper incorporation, high levels of crop or trash residues, stones or foreign matter and in areas of extremely high weed seed density such as header rows. For optimal efficacy and crop safety, avoid shallow seeding and ensure accurate seed placement that avoids placement of seed in the herbicide band. Avoid water repellent soils, soils subject to waterlogging or where furrow walls are likely to collapse. Duration and effectiveness of weed control will depend on use rate, soil type and rainfall or irrigation after application. Adequate rainfall should occur within 10 days of application, as this herbicide requires sufficient available soil moisture to ensure soil movement and uptake by emerging weed seeds.

APVMA Compliance Instructions for Mandatory COARSE or larger Droplet Size Categories

Important Information

These instructions inform users of this chemical product how to lawfully comply with the requirement of a COARSE or larger spray droplet size category for spray application. Spray droplet size categories are defined in the ASAE S572 Standard (newer name may also be shown as ASABE) or the BCPC guideline. Nozzle manufacturers may refer to one or both to identify droplet size categories, but for a nozzle to comply with this requirement, the manufacturer must refer to at least one. Complying with the label requirement to use a specific droplet size category means using the correct nozzle that will deliver that droplet size category under the spray operation conditions being used. The APVMA has approved only the following specific methods for choosing the correct nozzle. Use one of the methods specified in these instructions to select a correct nozzle to deliver a COARSE or larger droplet size category.

SECTION 1: Instructions for Ground Application – for COARSE droplet size or larger categories.

Mandatory Instructions for Ground Applications

USE ONLY nozzles that the nozzles’ manufacturer has rated to deliver a COARSE, a VERY COARSE or an EXTREMELY COARSE droplet size category as referenced to ASAE S572 or BCPC. Choose a nozzle specified to provide the droplet size category required in the label Spray Drift Restraints. DO NOT use a higher spray system pressure than the maximum the manufacturer specifies for the selected nozzle to deliver the droplet size category required in the label Spray Drift Restraints.

CROP TOLERANCE

DO NOT plant cereal crops at greater than 5 to 7cm. Overspraying of headlands or corners may result in crop damage. On heavy clay soils, crop thinning may occur in wheel tracks. The selectivity of Imtrade Diablo Duo Herbicide in cereals is a combination of positional and physiological selectivity. Positional selectivity must be maintained by sowing at adequate depth below the herbicide band. The physiological selectivity of Imtrade Diablo Duo Herbicide is given by the ability of cereals to metabolise the herbicide to inactive compounds more rapidly than susceptible weed species. Environmental factors such as rainfall events following application and soil type will influence product movement into the seed zone. Crop injury may occur when used in sandy soils with high leaching potential or in all soil types when heavy rainfall is received between sowing and emergence. Crop injury may also result from tank mixes with other herbicides or in the event of crop stresses including frost. Risk of crop damage may be exacerbated where varieties with short coleoptile length are planted in conjunction with the use of some fungicide seed treatments.

SOIL PERSISTENCE AND FOLLOWING CROPS

Under prolonged and extremely dry conditions Imtrade Diablo Duo Herbicide may persist for several months.

INCORPORATION BY SOWING

Incorporation by Sowing (IBS) with knife or blade points. Working speed should ensure adequate incorporation of product but avoid soil throw into the adjacent seeding row. Use of presswheels will minimize potential for herbicide to be dragged back into seeding rows. Weed control may be reduced in seeding rows as chemical displacement from this zone occurs, concentrating the herbicide in crop inter-rows. A knife or blade point is defined as being <12mm in width, having no wings, inverted T or blade and is generally on a minimum 200mm row spacing. Stubble coverage above 40-50% ground cover can reduce Weed control below acceptable levels. IMTRADE DIABLO DUO HERBICIDE MUST BE INCORPORATED INTO THE SOIL WITHIN 24 HOURS OF APPLICATION

MIXING

Imtrade Diablo Duo Herbicide is an emulsifiable concentrate that mixes readily with water. Fill the spray tank to one quarter full and add Imtrade Diablo Duo Herbicide. Continue adding water to make up to the final spray volume. Agitate while mixing and spraying. When tank mixing, wettable powder or water dispersible granule formulations should be added to the tank first followed by suspension concentrates (flowables), water soluble salts then Imtrade Diablo Duo Herbicide or other emulsifiable concentrate formulations. Maintain thorough agitation during mixing and application. Agitate tank-mixes vigorously if allowed to stand. Note: Tank-mix spray solution should NOT be left standing in the vat overnight.

APPLICATION

DO NOT apply by air. Emerged weeds should be controlled either by prior cultivation/application of a knockdown herbicide or by the tank mixing of a knockdown herbicide with Imtrade Diablo Duo Herbicide. Apply Imtrade Diablo Duo Herbicide by ground sprayer in 50 to 100L of water per hectare. Water rate selection should be based on soil type and stubble load. Stubble loads above 40 to 50% ground coverage can reduce weed control below acceptable levels. Water volumes greater than 70L/ha are recommended in order to reduce the impact of stubble in direct drill on minimum tillage systems. Spray rig booms should be fitted with flat fan nozzles delivering spray quality in the coarse to very coarse spray range. Use a spraying pressure of approximately 200 - 240kPa. Avoid application under strong and/or gusty wind conditions.

SPRAYER CLEAN-UP

After using Imtrade Diablo Duo Herbicide, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, drain the tank and clean any filters in the tank, pump, line and nozzles. To rinse: After cleaning the tank as above, quarter fill the tank with clean water and circulate through the pump, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.

COMPATIBILITY

Imtrade Diablo Duo Herbicide is compatible with any one of the following herbicides: Glyphosate, ChemAg Chlorsulfuron 750g/kg, Imtrade Mandate 750 WG Selective Herbicide, Imtrade Frenzy 750 Herbicide, Imtrade Trifluralin 480 EC Herbicide. DO NOT tank mix with 2,4-D Amine. Always refer to plant back restrictions on the label of the tank mix partner. As formulations of other manufacturer’s products are beyond the control of Imtrade Australia Pty Ltd and water quality varies with location, all mixtures should be tested prior to mixing commercial quantities.

Resistance Management

Large numbers of healthy surviving weeds can be an indication that resistance is developing. Efforts should be made to prevent seed set of the surviving weeds. DO NOT make more than 1 application of a Group J Herbicide with the inhibition of fat acid synthesis mode of action to a crop in the same season. If the user suspects that the target weed population is resistant to herbicides with this mode of action, Imtrade Diablo Duo Herbicide or other Group J Herbicides should not be used. Strategies to minimize the risk of herbicide resistance are available. The above recommendations should be incorporated into an Integrated Weed Management (IWM) Program that uses a diverse range of options to manage grass weeds and avoids over-reliance on any 1 method of control. Consult your local supplier, consultant, local Department of Agriculture, Primary Industries Department or an Imtrade Australia Pty Ltd representative for details.

Tank Mixes

Application of Imtrade Diablo Duo Herbicide at less than 2.25L/ha when tank mixing for Annual Ryegrass control WILL NOT be effective in the control of Group D resistant populations nor to delay the onset of herbicide resistance development. Tank mixing of herbicides is only effective in managing resistance where a lethal dose rate of each herbicide is applied.
