8. GENERAL DESCRIPTION:

A systemic fungicide for control of a range of fungal leaf diseases in crops. It has preventative, antisporulant and early curative action with leaf disease control for up to 6 weeks.
It contains a strobilurin and DMI active ingredient.

9. APPLICATION METHODS AND TIPS:

Best results when applied to actively growing crops in fine weather at least 2 hours before rain.
Ensure thorough coverage of leaves and stems. Apply at first sign of disease or as a protectant when disease risk is high.
Use mixed spray within 24 hours.
Application to stressed crops may give unreliable results. Use products with a different mode of action as follow up sprays.
Record details of application. No spray zones apply for aerial application.
Apples are sensitive, avoid drift onto trees.

10. ADJUVANTS, WETTERS, OILS:

None required.

11. EQUIPMENT:

Boom spray with flat fan nozzles at 100-400 kpa producing a fine to medium droplet.

12. SPRAYER WASH OUT AND DECONTAMINATION:

Thorough decontamination is required before using equipment on Apples as trace quantities may cause phytotxicity.

13. WATER OR CARRIER DATA:

50-100 L/ha water recommended.

14. WEATHER:

Apply in fine weather at least 2 hours before rain. Frosts before or after spraying may reduce disease control.

15. RAINFASTNESS:

2 hours

16. SOIL:

No specific effect of soil type but if plant growth is reducded by waterlogging or dry soils conditions then results may be unreliable. reducing

17. PLANT HEALTH and OTHER EFFECTS:

Good crop safety on cereals.
Some Apple varieties are very sensitive to azoxystrobin. Avoid drift onto Apples. Thoroughly decontaminate equipment before using on Apples. Treace amounts may cause significant phytotoxicity

18. WITHHOLDING PERIODS:

Harvest -
Avocado 7 days. Cucurbits, Passionfruit, Tomato 3 day. Grape, Potato 7 days. Mangoes 3 days. Poppies 6 weeks. Grazing - 21 days . Don't slaughter animals destined for export for at least 7 days after consumption of treated vegetation.

19. PLANT BACK PERIODS or RECROPPING INTERVALS:

20. MODE OF ACTION:

Preventative, early curative and antisporulant action. Relatively long lasting up to 6 weeks. Inhibits spore germintion and reduces spread.
Systemic and rapidly translocated
Combination of DMI(triazole) and strobilurin fungicide.

Difenoconazole has low mobility in soil.
Difenoconazole is eventually mineralised.
Ground water contamination
Accumulation in milk and tissues. Azoxystrobin has medium potential for bioaccumulation. Difenoconazole has high potential to bioaccumulate.
