4. ACTIVE INGREDIENTS: Copper sulphate 190-200 g/L

5. COST: $13.75 per L or kg.

6. CHEMICAL GROUP: M1.

7. RELATED PESTICIDES:

Copper hydroxide 375g/kg
Copper oxychloride 500-520g/kg
Copper sulphate 190-200 g/L

8. GENERAL DESCRIPTION:

An agricultural fungicide.

9. APPLICATION METHODS AND TIPS:

Applied as a dilute spray in most crops to reduce the risk of foliar damage due to salt burn.
Used within 3 hours of mixing and keep agitated.
Avoid conditions where slow or rapid drying of the spray occurs.
Best results if applied after rain before disease spores germinate.

10. ADJUVANTS, WETTERS, OILS:

Wetting agents and bonding agents are normally used and essential for Brassica, Legume and Onion crops

11. EQUIPMENT:

High volume sprayers usually used, Concentrate sprayers and aerial application for some crops.
Thorough coverage is essential for good disease control.

12. SPRAYER WASH OUT AND DECONTAMINATION:

Water plus wetting agent or detergent.

13. WATER OR CARRIER DATA:

20 L/ha for aircraft.
250 L/ha minimum for booms and ground applications. Normally 400-1200 L/ha used to obtain good coverage with minimal burning.

14. WEATHER:

Best results in fine weather. Use a bonding agent if rainy weather expected later.

15. RAINFASTNESS:

10-20 minutes

16. SOIL:

No significant effects.

17. PLANT HEALTH and OTHER EFFECTS:

May cause salt burn especially in hot fast drying conditions.

18. WITHHOLDING PERIODS:

19. PLANT BACK PERIODS or RECROPPING INTERVALS:

None required.

20. MODE OF ACTION:

Not translocated effectively enough for the control of disease.

21. PESTICIDE RESISTANCE:

Some species may be resistant or develop resistance with continued application. Rotate with products from alternative groups.

22. TOXICITY:

Poison schedule - S6

23. TOXICITY SYMPTOMS:

Stomach pains if quantities are swallowed.

24. FIRST AID:

If SWALLOWED - Rinse mouth with water. Do NOT induce vomiting. See a doctor.
If in EYES - Irrigate for 15 minutes with plenty of water. See a doctor if symptoms persist.
If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water.
If INHALED - Remove patient to fresh air.
If patient has symptoms or is concerned contact a doctor immediately.
Advice to doctor - Treat symptomatically. No specific antidote.
Remove by gastric lavage. Symptoms of stomach pains, symptoms attributed to the CNS and kidney, haemolytic crisis accompanied by damage in the liver and brain.

26 RE ENTRY PERIODS and OTHER SAFETY ISSUES:

27. PROPERTIES:

Product appearance - Greenish blue liquid.
Shelf Life -
Product Flammability - Not flammable.
Half life in water - many days at pH5 and 35 C. Usually sediments out due to formation of copper complexes.
Water solubility at 25 C. - very soluble. 230.5 mg/L at 25C.
Oil solubility -
Octanol:Water ratio at 25 C. - at pH 5.
Sorption to soil Koc - Strong.
Vapour Pressure at 25 C. - Low. Non volatile.
Dissociation constant - pKa.
Melting point - C.
Boiling point - 100C in water.
Molecular weight -
Density - 1.28 g/cm3
pH - 6.5-8 at 12.8 g/L

28. ENVIRONMENTAL FATE:

Summary - As a natural component of most soils it is not expected to cause problems.
Birds - toxicity.
Fish - Medium-high toxicity LC50 >100 ppm. Less toxic in cool, hard water. Toxicity varies with species of fish.
Invertebrates - High toxicity. EC50 (48hr) for daphnia magna is 0.61 mg/l for tribasic copper sulphate.
Bees - Not toxic.
Bacteria LC50 100 mg/L
It has a half life in soil of many years. Both copper and sulphate are plant nutrients and are removed from the environment by export of produce. Bound to organic matter and mineral surfaces.
It has an EPA classification for soil mobility that ranges from
Ground water contamination unlikely as it is immobile in most soils. Low likelihood of leaching. Low likelyhood of run off.
Accumulation in milk and tissues.
pH stability - Stable
Photolysis rate -
Hydrolysis half life -
Biodegradation rate - adsorption inhibits bio availability.

29. COMPATIBILITY:

See HerbiGuide for compatibility with other herbicides, insecticides and fungicides.
See HerbiGuide for a full list of pesticide compatibilities. Add other pesticides before copper sulphate.
Compatible with spray oils, urea and many insecticides.
Not compatible with some foliar fertilizers.

30. REGISTERED CROPS, INSECTS and DISEASES.
