Phos600™ an alternative to Foschek is absorbed by the plant and translocated via the xylem and phloem to all parts of the plant. Phos600™ alsocontains Potassium, as the relationship between Nitrogen and Potassium is critical to driving balanced growth.
Active Ingredient:
600 g/litre Phosphorous Acid as the mono and di potassium salts in the form of a soluble concentrate.
Product Overview:
– Type: Fungicide + fertiliser (phosphonate).
– Strength: Higher concentration than typical 400 g/L products.
How It Works:
– Systemic movement → travels via xylem & phloem.
Provides:
– Protectant action (prevents infection).
– Curative action (suppresses early infection).
Targets:
– Phytophthora.
– Pythium.
– Downy Mildews.
Key Differences:(Important)
Compared to Phos400 / Phostemic,Phos600 = Higher Strength (600 g/L vs 400 g/L).
→ Requires lower rates per hectare or per 100 L.
→ More cost-efficient per unit active.
Rule Of Thumb:
– 600 g/L product ≈ ⅔ the rate of a 400 g/L product.
General Use Guidance: (Label Intent)
(Full rate tables weren’t visible, but standard Phosphonate use applies)
Use:
– Foliar Spray (to runoff).
– Soil Drench.
– Trunk Injection (Woody Crops).
Best Results:
– Preventative or early infection.
– Repeat applications in disease pressure.
Application Guide.
FERTILISER:
Avocado:
Skeletal Trees.
1st year 1 part Phos600 to 2 parts water.
Other Situations.
1 Part Phos600 to 4 parts water.
– Timing: Every 3 weeks.
– Application: Spray to runoff (full coverage essential).
Cucurbits:
– Rate: 3 – 4 L/ha.
– Timing: Every 7 days.
– Continue: Until symptoms disappear.
Vegetables:
– Rate: 2 – 3.5 L/ha.
– Timing: Every 7 days.
– Continue: Until symptoms disappear.
FUNGACIDE:
Ornamentals:
– High volume 335ml/100Lt water.
– Knapsack 4ml/Lt water.
– Mistblower 17ml/Lt water.
– Apply at 4 week intervals.
– Avoid spraying during plant stress.
– Avoid extreme temperatures.
Turf:
– 5 -7ml per 10 square metres of turf.
– 5 – 6.7Lt /Ha in sufficent water to wet the foliage.
– Prewet the thatch and apply Phos600, then immediately apply sufficent overhead irrigation to rewet the thatch.
Application Rates:
– Knapsack: 4ml/Lt water (16ml/15Lt).
– Mistblower: 165ml/10Lt water.
– High Volume Spray Gun: 375ml/300Lt water.
Safety Summary:
– Causes eye irritation (Category 2).
– Hazardous to terrestrial vertebrates.
Basic PPE:
– Gloves.
– Eye Protection.
– Protective Clothing.
Emergency Info:
NZ emergency line: 0800 CHEMICALL (0800 243 622)
Practical Takeaways:
– Same mode of action (Group 33) as other phosphonates.
– Main Advantage = Concentration.
Best used as part of a repeat programme in high disease pressure systems (e.g. avocados, veg).
Note: Not registered as a fungicide.
Caution:
Must be used strictly according to label directions.
Available in 20L, 200L, 1000L
