Multiplex Multiclear is a systemic crop disease-management product containing Potassium Phosphite. It is developed to help inhibit the growth and sporulation of oomycetes and support the plant's natural disease-resistance response under proper application practices.
Multiclear is absorbed by plants and has a high degree of phloem mobility, allowing it to move to different plant parts. It is useful against label-listed diseases such as late blight, downy mildew, damping-off, dieback and certain wilts associated with pathogens such as Phytophthora and Pythium species.

| Recommended Dose | 3–4 ml per litre of water |
| Target Pathogens | Oomycetes, including certain Phytophthora and Pythium species |
| Recommended Crops | Various vegetable and fruit crops; use only according to the label |
| Available Pack Sizes | 500 ml, 1 litre and 5 litre |
| Active Ingredient | Concentration | Primary Role |
|---|---|---|
| Potassium Phosphite | As stated on the product label | Supports systemic management of label-listed oomycete diseases |
Composition note: Multiplex identifies Potassium Phosphite as the active ingredient but does not state its concentration on the currently available official product page. Confirm the exact concentration from the physical product label before adding it to the listing.
| Target Disease | Associated Pathogen Group | General Crop Areas Affected |
|---|---|---|
| Late blight | Oomycetes such as Phytophthora species | Leaves, stems and developing crop parts |
| Downy mildew | Oomycete pathogens | Leaves, shoots and inflorescences |
| Damping-off | Pythium and related pathogens | Seeds, roots, collars and young seedlings |
| Dieback | Label-listed susceptible pathogens | Shoots, twigs and growing points |
| Fungal or oomycete-related wilt symptoms | Phytophthora, Pythium or other label-listed pathogens | Roots, collar region and vascular crop parts |
Accurate diagnosis is important because similar symptoms can be caused by fungi, bacteria, waterlogging, root injury or nutrient disorders. Multiclear should only be used where the suspected disease and crop are covered by the product label.
| Crop Group | Potential Disease Use | Treatment Area |
|---|---|---|
| Vegetable crops | Late blight, downy mildew, damping-off and susceptible wilts | Foliage, inflorescence and affected crop parts |
| Fruit crops | Dieback, downy mildew and Phytophthora-related disease pressure | Leaves, shoots, inflorescence and affected areas |
| Nursery and young plants | Damping-off and susceptible root or collar diseases | Use only through the label-approved method |
The official product information broadly refers to various vegetable and fruit crops. Confirm the exact registered crop, disease and application method from the product label before spraying.
| Application | Recommended Dose | Method |
|---|---|---|
| Foliar spray | 3–4 ml per litre of water | Spray uniformly on the inflorescence and affected crop areas |
| 15-litre spray pump | 45–60 ml | Based on the official recommendation of 3–4 ml per litre |
| 16-litre spray pump | 48–64 ml | Based on the official recommendation of 3–4 ml per litre |
| 200-litre spray solution | 600–800 ml | Adjust total quantity according to the actual spray-water requirement |
Dose note: Apply 3–4 ml per litre of water or follow the current product-label recommendation. The spray-water volume per acre depends on crop size, canopy density, equipment and the area requiring coverage.
Multiplex Multiclear is taken up by the plant and has a high degree of phloem mobility. This systemic movement helps distribute the active ingredient to different plant parts after proper application.
Potassium phosphite helps inhibit the growth and sporulation of susceptible oomycetes. It also supports the activation of plant defence responses, providing a combination of direct pathogen-growth suppression and indirect plant-resistance support.
Multiplex Multiclear is a systemic disease-management product containing Potassium Phosphite. It helps manage label-listed diseases caused by susceptible oomycete pathogens.
It is useful against label-listed late blight, downy mildew, damping-off, dieback and certain wilt conditions associated with pathogens such as Phytophthora and Pythium species.
The official recommended dose is 3–4 ml per litre of water. This equals 45–60 ml for a 15-litre spray pump.
Yes. The manufacturer states that it is taken up by plants, has high phloem mobility and is translocated to different plant parts.
No. It is primarily intended for susceptible oomycete-related diseases and other diseases specifically listed on its label. It should not be treated as a universal solution for every fungal or bacterial disease.
It may be used at the first sign of a label-listed disease. Early application and complete coverage generally support better disease management than application after severe field-wide infection.
Do not combine it with unfamiliar products without checking the label and confirming compatibility. Conduct a small jar test and consult a qualified agricultural professional before preparing a tank mixture.
The manufacturer states that Multiclear supports increased mycorrhizal colonisation. The actual response can vary with soil conditions, crop, microbial population and overall farm management.
