Zeemil 250 EC Systemic Fungicide

Zeemil 250 EC Systemic Fungicide 5L by UPL is a systemic agricultural fungicide formulated for the control of Phytophthora Heart Rot and Root Rot in pineapples.

The concentrated formulation contains 250 g/L metalaxyl, a phenylamide fungicide that moves within plant tissue to help protect susceptible plants from Phytophthora infection. Zeemil 250 EC is classified as a Group 4 fungicide for resistance management.

Available in a professional 5L pack, Zeemil 250 EC is suited to commercial pineapple disease-management programs where systemic Phytophthora control is required.

What Does Zeemil 250 EC Control?

Zeemil 250 EC is registered for the control of:

• Phytophthora Heart Rot

• Phytophthora Root Rot

• Diseases caused by Phytophthora species

• Registered crop: Pineapples

The fungicide is intended to protect pineapple foliage, the growing point and root zone as part of a correctly timed disease-management program.

Zeemil 250 EC Active Ingredient

• Active constituent: 250 g/L Metalaxyl

• Fungicide group: Group 4

• Chemical group: Phenylamide

• Formulation: Emulsifiable concentrate

• Product type: Systemic fungicide

• Pack size: 5L

• Manufacturer: UPL Australia

Metalaxyl provides systemic activity, allowing the active constituent to move within treated plants rather than relying solely on surface protection.

Zeemil 250 EC Dosage

According to the UPL Zeemil 250 EC label, the registered high-volume application rate for pineapples is:

• 2 L of Zeemil 250 EC per hectare

• Apply in 2,000–5,000 L of water per hectare

• Young pineapple plants: approximately 2,000 L water/ha

• Larger plants: increase spray volume up to 5,000 L water/ha

The amount of Zeemil remains 2 L/ha while the required water volume changes according to plant size and the coverage required.

Zeemil 250 EC Mixing Rate

Because the registered rate is specified per hectare rather than as one universal mL-per-litre rate, Zeemil should be mixed according to the total spray volume being used.

Based on the registered 2 L/ha rate:

• 2 L product in 2,000 L water = approximately 1 mL/L

• 2 L product in 5,000 L water = approximately 0.4 mL/L

These figures simply represent the equivalent concentration at the label's specified spray volumes. Application should still be calculated using the registered 2 L/ha rate rather than treating the product as having a universal per-litre dosage.

How to Use Zeemil 250 EC

For registered pineapple applications:

• Pour the required quantity directly into water in the spray tank.

• Mix thoroughly before application.

• Spray pineapple foliage and the surrounding soil thoroughly.

• Apply immediately after planting.

• Repeat applications at 4–8 week intervals during summer, autumn and winter.

• Use the shorter interval during wet weather or where there is a previous history of Phytophthora disease.

• For the first treatment, the label indicates that hand drenching is preferred to spraying.

• Use sufficient spray volume to achieve thorough coverage.

UPL also specifies that Zeemil 250 EC should be applied in alternate years only, with other recommended fungicides used in intervening years as part of resistance management.

Systemic Action Against Phytophthora

Zeemil contains metalaxyl, a systemic fungicidal active ingredient particularly associated with control of oomycete pathogens such as Phytophthora.

Systemic movement helps protect plant tissues from within, making Zeemil suitable for targeted disease-management programs where Heart Rot and Root Rot are a known risk in pineapple production.

For best disease management, applications should be correctly timed and combined with appropriate cultural and resistance-management practices.

Fungicide Resistance Management

Zeemil 250 EC is a Group 4 fungicide. Repeated use of fungicides from the same mode-of-action group can favour resistant fungal populations.

UPL therefore specifies:

• Do not rely continuously on Zeemil 250 EC.

• Apply Zeemil in alternate years.

• Use other recommended fungicides in intervening years.

• Follow recognised fungicide resistance-management strategies.

This is particularly important with metalaxyl products because resistant Phytophthora populations may not be adequately controlled by repeated Group 4 treatments.

Withholding Period

For the registered pineapple use:

• Do not harvest for 4 weeks after application.

The treated area should also not be re-entered until the sprayed crop is dry.
