Growers should note that Maximum Residue Limits (MRLs) or import tolerances may not exist in all markets for produce treated with Lavor 250 SC. If you are growing produce for export, please check with Kenso Agcare Pty Ltd for the latest information on MRLs and import tolerances BEFORE using Lavor 250 SC.


Kenso Agcare Lavor 250 SC Fungicide is a member of the dicarboximide group of fungicides. For fungicide resistance management, the product is a Group 2 fungicide. Some naturally occurring individual fungi resistant to the product and other Group 2 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungal population if these fungicides are used repeatedly. These resistant fungi will not be controlled by this product or other Group 2 fungicides, thus resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use, Kenso Agcare Pty Ltd accepts no liability for any losses that may result from the failure of this product to control resistant fungi.


Resistant strains of fungi can develop to this and other fungicides. To reduce the possibility of this occurrence, and where alternatives are available, rotate to use products with as many different modes of action as possible. Where specific resistance management strategies are established, these are detailed in the Critical Comments.


Note: Lavor 250 SC may be unstable in conditions where the pH is 7 or higher. It is therefore essential to check the pH of the spray solution before adding Lavor 250 SC. A suitable registered buffering agent may have to be added to bring the pH down below 7. Shake well before use. Add half the required water volume to the spray tank or vat with the agitation mechanism operating. Add the required volume of this product and then add additional water to the volume required.


Good disease control requires even, thorough coverage of the target area. Application should be made using appropriate spray equipment and sufficient water to provide adequate penetration and coverage. Equipment settings and water volume may need to vary, depending on the growth stage of the crop. High pressure, prolonged, and vigorous agitation, particularly in conjunction with a high concentration of Lavor 250 SC in the spray tank, may reduce the suspension properties of Lavor 250 SC, resulting in a scum forming on the surface or sediment forming on the filters. If the agitation system cannot be adjusted, or concentration reduced to overcome this problem, it is recommended that another be used, where registered.


Dilute Spraying:

  • Use a sprayer designed to apply high spray volumes, up to the point of run-off and matched to the crop being sprayed.

  • Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient spray solution to cover the crop to the point of run-off. Avoid excessive run-off.

  • The required spray volume to achieve the point of run-off may be determined by applying different test volumes, using different settings on the sprayer, or from industry guidelines or other expert advice.

  • Add the amount of product specified in the Directions for Use table for each 100 L of water. Spray to the point of run-off.

  • The required dilute spray volume to achieve the point of run-off will change, and the sprayer set up and operation may also need to be changed, as the crop grows.

Concentrate Spraying:

  • Use a sprayer designed and set up for concentrate spraying (i.e., a sprayer that applies spray volumes less than those required to reach the point of run-off) and matched to the crop being sprayed.

  • Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen spray volume.

  • Determine an appropriate dilute spray volume (See Dilute Spraying above) for the crop canopy. This is needed to calculate the concentrate mixing rate.

  • The mixing rate for concentrate spraying can then be calculated in the following way:


  1. Dilute spray volume as determined above: For example, 1500 L/ha.

  2. Your chosen concentrate spray volume: For example, 500 L/ha.

  3. The concentration factor in this example is: 3 X (i.e., 1500 L ÷ 500 L = 3).

  4. If the dilute label rate is 10 mL/100 L, then the concentrate rate becomes 3 x 10, that is 30 mL of product per 100 L water for concentrate spraying.

  • The chosen spray volume, amount of product per 100 L of water, and the sprayer set up and operation may need to be changed as the crop grows.

For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.


Lavor 250 SC is compatible with the following products: fosetyl-aluminnium (see NOTE below), carbaryl, chlorfenvinphos, Kensban 500, Kencozeb 750, fenarimol, dicofol, Kocide* (Warning: Do not mix Lavor 250 SC with Kocide for use on potatoes), thiodicarb, maldison, Kenso Agcare Methomyl 225, metalaxyl, methamidophos, Piri-Ken 500, propargite, triadimenol. When tank mixing products, the order of mixing is determined by formulation type. As a guide, the following mixing sequence is recommended:

  1. Wettable powders

  2. Suspension concentrates

  3. Water Dispersible Granules

  4. Suspo-emulsions (e.g., Lavor 250 SC)

  5. Soluble powders

With any mixture, thoroughly agitate immediately before applying. It is not recommended to mix this product with more than one of the above chemicals in the tank. The use of a surfactant or spray oil is not recommended with Lavor 250 SC as it may result in crop damage to sensitive plants. DO NOT mix with fertilisers. Mixtures with some fertilisers, e.g., urea, may cause foliar damage.

NOTE: Mixing Lavor 250 SC with fosetyl-aluminium may result in some settling out. As formulations of other manufacturers' products are beyond the control of Kenso Agcare Pty Ltd, all mixtures should be tested prior to mixing commercial quantities.


DO NOT apply the product under weather conditions, or from spraying equipment, which could be expected to cause spray drift onto adjacent crops, croplands, pastures, livestock, natural or impounded lakes, dams, or other waterways.


Toxic to aquatic organisms. DO NOT contaminate streams, rivers, or waterways with the chemical or used containers.
