4. ACTIVE INGREDIENTS: Mancozeb 640g/kg + metalaxyl 80g/kg
5. COST: $49.50 per L or kg.
6. CHEMICAL GROUP: Y,D.
7. RELATED PESTICIDES:
Mancozeb 640g/kg + metalaxyl 80g/kg
8. GENERAL DESCRIPTION:
A mixture of agricultural fungicides combining a non systemic protectant (mancozeb) with a systemic, curative (metalaxyl) active ingredient.
9. APPLICATION METHODS AND TIPS:
Apply by high volume, low volume ground sprayers or aircraft.
Used mixed product within a few hours as mancozeb has a half life of only 1-2 days in water.
10. ADJUVANTS, WETTERS, OILS:
Wetting agent recommended for some crops.
11. EQUIPMENT:
High volume, low volume and aerial equipment may be used.
Ensure sprayer provides thorough and even coverage of foliage.
12. SPRAYER WASH OUT AND DECONTAMINATION:
Triple rinse with water plus wetting agent.
13. WATER OR CARRIER DATA:
1000 L/ha for high volume spraying.
200-500 L/ha for low volume spraying.
20-40 L/ha for aerial spraying.
14. WEATHER:
Apply in fine conditions. Rainfast in 6 hours.
15. RAINFASTNESS:
6 hours
16. SOIL:
No effect of soil type expected.
17. PLANT HEALTH and OTHER EFFECTS:
18. WITHHOLDING PERIODS:
Cuccurbits: Harvest - 7 days
Lettuce: Harvest - 14 days
Onions: Harvest - 7 days
Potatoes: Harvest - 7 days
Tobacco: Harvest - 7 days
Cuccurbits: Harvest - 7 days
Lettuce: Harvest - 14 days
Onions: Harvest - 7 days
Potatoes: Harvest - 7 days
Tobacco: Harvest - 7 days
19. PLANT BACK PERIODS or RECROPPING INTERVALS:
None required
20. MODE OF ACTION:
Metalaxyl is systemic and curative.
Mancozeb is non systemic and protective with multiple sites of action.
21. PESTICIDE RESISTANCE:
Some species may be resistant or develop resistance with continued application. Rotate with products from alternative groups.
22. TOXICITY:
Poison schedule - S5
Summary: Practically non toxic by oral or skin exposure. It is a mild skin irritant and sensitiser and a mild to moderate eye irritant.
Details:
Poison schedule - S5
Mammalian toxicity -
Acute oral LD50 - >5000-11200 mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - > 5000-10000 mg/kg (rabbit).
Skin - Mild irritant and sensitiser. Occupational exposure may lead to sensitisation rashes.
Eye - Mild to moderate irritant.
Vapour inhalation - LC50 - > mg/L air (rat).
Chronic oral toxicity NOEL - ppm for two years.
Mancozeb may be not mutagenic or weakly mutagenic on available evidence.
There is conflicting evidence from animal tests on the teratogenicity of mancozeb.
Mancozeb is probably not carcinogenic but one of its breakdown products (ETU) probably is.
Mancozeb inhalation levels of 55mg/m3 caused embryotoxic effects in rats at levels that were toxic to the dams.
It is not likely that mancozeb will produce reproductive effects in humans at normal exposure levels.
Acceptable Daily Intake (ADI) - For Mancozeb 0.006 mg/kg/day (NOEL 0.6 mg/kg/day). For Metalaxyl 0.03 mg/kg/day (NOEL 3 mg/kg/day)
Chronic effects - Impaired thyroid function has been shown in some studies with dietary intakes of >=2.5 mg/kg/day mancozeb.
ETU (ethylenethiourea) is a major toxicological concern as it can be produced in mancozeb breakdown, as a contaminant, from EDDC's used on stored produce and during cooking. ETU can cause goitre and ahs produced birth defects and cancer in test animals.
Mancozeb is rapidly absorbed from the gastrointestinal tract and almost completely excreted within 96 hours. ETU is major metabolite of toxicological significance and carbon disulfide is minor metabolite.
23. TOXICITY SYMPTOMS:
People with occupational exposure to have developed sensitisation rashes to Mancozeb.
Nothing more than transient discomfort should occur.
24. FIRST AID:
If SWALLOWED - Rinse mouth with water.
If in EYES - Irrigate water to remove product.
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.

28. ENVIRONMENTAL FATE:
Summary -
Birds - Low toxicity. LC50 >3200-10000 ppm
Fish - Moderate to high toxicity LC50 2.2-9 mg/L.
Invertebrates - Moderate toxicity. LC50 40 mg/L
Bees - Not toxic.
Mancozeb has a half life in soil of 1-7 days. Degrades to ETU in the presence of water and oxygen which has a half life of 5-10 weeks
Mancozeb has a half life in water of 1-2 days.
Mancozeb has an EPA classification for soil mobility that is low
Ground water contamination - Mancozeb is unlikely to contaminate ground water because of its low solubility. ETU may be mobile in soils and has been detected at 0.016 ppm in 1 of 1295 wells tested.
Accumulation in milk and tissues.
Degrades to ETU in the presence of water and oxygen.
