Not considered to be toxic to humans. Product may irritate eyes and skin upon contact. In keeping with good industrial hygiene practises, exposure should be kept to a minimum.

Product Description: Grow Green Phoscal Phosphorous Acid Fertilizer is a liquid agricultural fertilizer to be diluted with water and applied through irrigation lines (not foliar – applied irrigation) or sprayed on soil.

For advice contact the Poisons Information Centre (Phone 131126).

May cause eye irritation. If in eyes, flush eyes with running water for at least 15 minutes, keeping eyelids open. Obtain medical attention if irritation persists.

Wash contaminated skin with soap and water.

No treatment normally required if swallowed.

If inhaled seek medical advice.

This material is a water based suspension which is not flammable.

Suitable Extinguishing Media: Not Applicable

Specific Hazards: Not Applicable

Fire fighting advice: Not Applicable

Hazchem Code: Not Hazardous

It is advisable to clean up small spills with sand, diatomaceous earth, soda ash, or other absorbent material, since washing fertilizers into waterways may upset nutrient balances. Load absorbent mixture into suitably labelled containers for disposal.

The material collected can be disposed of at an approved local authority landfill site.

Toxicological Data:

The oral median lethal dose (LD 50 ) for 10% phosphonic [phosphorous] acid in water is 1.5 grams of pure acid/kg body weight. This places the Technical Active Ingredient in Class III of the World Health Organisation classification. Class III is the “slightly hazardous” class and phosphonic [phosphorous] acid is at the very low end of the scale within this class. Twenty percent (20%) and forty percent 40% products have been formulated to eliminate the very slight poisonous and corrosive properties of the Technical Active Ingredient.

Furthermore, the formulated products are safer than the Technical Active Ingredient because they are neutralised with potassium phosphite. Phosphite has a pH of 5.7-6.0 which is comparable with that of the skin and therefore will not cause dermal irritation and is not corrosive to the skin or eyes. Contact with the skin is likely to cause only mild irritation to cuts or mucous membranes.

The LD 50 for a 200 g/L product is of the order of 23.6 grams/kg bodyweight and is classified as “not poisonous” by Australia's National Health and Medical Research Council.

Ecotoxicity:

Estimated LD50 to fish is approximately 1.5 g/l.

The chemical is not broken down in animals and is excreted in the normal way.

In the soil phosphite is slowly broken down to phosphate by microflora.

The slightly acid pH lowers the likelihood of phytotoxicity in plants. Application of phosphite to native plant species generally does not cause chemical leafburning when the fungicide is applied at recommended rates. Higher rates or treatments applied under unfavourable environmental conditions, or at flowering, are likely to result in chemical burning of foliage and can affect the reproductive capabilities of sprayed plants. Species vary in their susceptibility to chemical burning, with certain eucalypt species being amongst those most likely to suffer leaf-burning.

It is advisable to clean up small spills with sand, diatomaceous earth, soda ash, or other absorbent material, since washing fertilizers into waterways may upset nutrient balances. Load absorbent mixture into suitably labelled containers for disposal.

The material collected can be disposed of at an approved local authority landfill site.
