Product Description

Precision Wetter is an innovative product based on advanced organo-modified siloxane technology. It is a highly effective non-ionic wetting agent designed for use on all water repellent soils, including agricultural, forestry, turf and ornamental, industrial and other non-crop land. The advantage of organosilicone surfactants is their ability to enable water droplets to spread to a greater degree than occurs with conventional non-ionic surfactants. Water treated with conventional soil wetters tends to percolate straight down through the soil, whereas water treated with Precision Wetter tends to spread horizontally and vertically through the soil.

Precision Wetter comes in 110 litre, 200 litre and 1,000 litre containers

Application Rates

Specific use rates will vary with conditions of application, such as water hardness, application method, equipment, spray droplet size etc. Higher rates than those recommended below may be used; however do not add this product at a rate which exceeds 10% of the finished spray volume.

Broadacre Band Spray for furrow seeding Press wheels at 25cm spacing 0.6 to 2L/ha Maintain spray pressure at a rate high enough to produce a strong jet. Water rate: 50 to 100L/ha. Use higher rates for extremely high water repellent soils.
Press wheels at 15cm spacing 1 to 4L/ha
Boom Spray 4 to 8L/ha Ideally spray immediately before rain is due
Seedling establishment Band spray: 1 to 3L/ha
Boom spray: 5 to 10L/ha
Water rate: 75 to 100L/ha
Landscaping with foliage 5 to 10 L/ha Preferable to water immediately after application to ensure soil contact.
Turf Management Boom spray: 2.5 to 5L/ha Water rate: 400 to 800L/ha
Apply every 15 to 30 days. Water well after application to ensure soil contact

Precision Wetter is compatible with most pesticides and liquid fertilisers. However, if the desired combination has not previously been used a jar test is recommended.


Fill spray tank half to three quarters full of water and turn on agitator, add Precision Wetter and fill tank to required capacity. If mixing with pesticides or liquid fertilisers, add product as directed by product label or use the following sequence: Fill spray tank half to three quarters full of water. If adding more than one pesticide add in this order: Water dispersible granules, wettable powders, suspension concentrates, solutions, emulsifiable concentrates. Add liquid fertilisers last. Finally add Precision Wetter and fill tank to capacity. Continuous agitation of spray tank is recommended. For optimal results use the spray solution within 36 hours of mixing. If spray solution has been left to stand, thoroughly agitate before using. Thoroughly rinse spray system with clean water after use to minimise corrosion.

Storage and Disposal

Store in closed, original container, in a cool well ventilated area away from children, animals, food and feedstuffs. Do not store for long periods in direct sunlight. Do not allow spilt product to enter sewers, gutters or storm water drains, creeks or other waterways. Triple rinse containers before disposal. Add rinsings to spray tank. Dispose of surplus product by using according to the directions for use. Do not reuse empty container.

Safety Directions

Avoid contact with eyes and skin. Do not inhale vapour or spray mist. If product in eyes, wash it out immediately with water.

First Aid Directions

If swallowed do not induce vomiting, give a glass of water to drink. If in eyes, hold eyes open, flood with water for at least 15 minutes and see a doctor.

Environmental Statements

Do not apply directly to water, or to areas where surface water is present. Do not contaminate water when cleaning equipment or disposing of wash water.


Surfactants are common ingredients in many household products and generally end up in sewage treatment systems or natural waterways. Surfactants used in these products are chosen to break down rapidly under the action of micro-organisms so that these compounds do not accumulate and cause environmental problems. Surfactants that break down rapidly are classified as biodegradable. Precision Wetter is not manufactured using biodegradable surfactants because soil wetters are designed to continue working for weeks without reapplication. Ultimately the surfactants in Precision Wetter will break down under the action of sunlight, moisture, bacteria and oxygen to carbon dioxide, water and silicates.
