18. WITHHOLDING PERIODS:

19. PLANT BACK PERIODS or RECROPPING INTERVALS:

20. MODE OF ACTION:

A systemic, phenylamide, group D fungicide with protective and curative action that inhibits protein synthesis in some fungi.
Foliar applications are absorbed by the leaves and stems and translocated throughout the plant. It is not root absorbed from the soil

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: Harmful if swallowed.
Details:
Poison schedule - S5
Mammalian toxicity -
Acute oral LD50 - 669 mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - >3100 mg/kg (rats).
Skin - Slight irritant. Not sensitizing.
Eye - Slight irritant.
Vapour inhalation - LC50 - > mg/L air (rat).
Chronic oral toxicity NOEL - ppm for two years.
Not mutagenic or teratogenic (i.e. does not cause reproductive problems).
Studies of the carcinogenicity are inconclusive.
Results from animal tests on carcinogenicity are inconclusive.
May cause liver damage with long-term exposure.
Acceptable Daily Intake (ADI) - 0.03 m/kg/day
NOEL - 3 mg/kg/day.
Chronic toxicity: A 90-day study of rats exposed to 0.1 to 2.5 mg/kg/day in diet, showed some cellular enlargement in the liver at the highest dose. In a similar study with dogs fed diets of approximately 0.04 to 0.8 mg/kg/day for 6 months, the dogs were adversely affected by the highest dose. Manifestations included increased blood alkaline phosphatase and increased liver-to-brain weight ratio.
Fate in humans and animals: Studies with rats and goats showed rapid metabolism and excretion via the urine and
faeces. Metalaxyl is metabolized to a variety of products before excretion. Forty-day feeding studies with dairy cattle
at 15 ppm/day, showed less than 0.01 ppm was stored in the muscle and fat. The liver contained 0.13 to 0.20 ppm
and the kidney 0.26 to 0.83 ppm. Chickens fed for 28 days at 5 ppm in the diet had less than 0.05 ppm in the eggs,
skin, fat, breast, and thigh, and less than 0.1 ppm in the liver.

23. TOXICITY SYMPTOMS:

24. FIRST AID:

If SWALLOWED - Rinse mouth with water. If more than 15 minutes from hospital, induce vomiting preferably with Ipecac Syrup APF.
If in EYES - Irrigate for 5 minutes with plenty of water.
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.

Safety goggles and face shield.
Elbow length PVC gloves.
Cotton overalls and washable hat.
Boots.

28. ENVIRONMENTAL FATE:

Summary -
Birds - Practically non toxic.
Fish - Practically non toxic. LC50 >100 ppm.
Invertebrates - Practically non toxic. LC50 12.5-28 mg/L
Bees - Practically non toxic.
It has a half life in soil of 7-170 days and typically 70 days. Breaks down in sunlight.
It has an EPA classification for soil mobility that ranges from
Ground water contamination - may contaminate ground water.
Accumulation in milk and tissues. Did not accumulate beyond 7 times background levels and quicly eliminated when fish placed in metalaxyl free water.
The parent compound is the major residue in potato tubers and grapes, but in potato leaves and on lettuce, metabolites are the major product.
