Dryacide is an inert mineral dust for insect pest control that's effective, economical, long term and environmentally safe.

Material Safety Data Sheet

Dryacide Applications?

Dryacide controls all economically important stored grain insect pests including weevils, beetles, borers and moths. It provides 12 months protection against insect pests in:

Stored products such as wheat, barley, rice, corn, sorghum, lentils, peas and other food commodities.

Dryacide can also be used strategically in Integrated Pest Management programs

Warehouses and Storage areas for food products.
Empty silos and grain handling machinery such as combine harvesters, belt conveyors and bucket elevators.
Who can benefit from using Dryacide?
Large Industrial and Government Organizations handling food commodities.
Farmers, Small Cooperatives, Importers and Exporters storing food commodities and feed or seed grain.
Flour Mills and Bakeries storing their own grain.
Feed Producers and Food Processors.
Poultry, Cattle, Sheep and Pig Farmers and other Stock Producers.
Dryacide is... Safe for the environment.

Dryacide is a harmless, non-toxic amorphous silica powder that absorbs the wax on insects. Without their wax coating, insects quickly dry out and die. This non-chemical approach to insect control offers major benefits:

... No Residue
Treated commodities remain chemical and residue free. This is an important issue for Organic Growers, Exporters and other producers of residue-free food products. Dryacide is approved for use by Australia's largest Organic Growers Association.
... Superior Cost/Performance
Whether used for stored commodity protection or structural treatment of warehouses and food stores, Dryacide provides very long-term protection, (normally one year or more). This is because the product works by a physical absorption process and does not contain chemicals which can break-down or degrade. Unlike chemical insecticides, it is totally unaffected by high or low temperatures, yet treatment costs are no more than those of conventional chemical treatments for structural treatments.
... Additional benefits include
* 100 percent effectiveness against common insect species including those resistant to chemical insecticides.
* treated grain or other food commodity has no withholding period and can be used any time after treatment.
* complete protection in normal, vented silos and horizontal storage areas subject to repeated infestation pressure. Sealed storage facilities are not required.


And you can be sure it works...

The Australian Commonwealth Scientific and Industrial Research Organization (CSIRO) is one of the world's leading research organizations. Much of the basic research and many field trials on Dryacide have been conducted or supervised by this organization. They have confirmed its effectiveness. Many grain-growers and Bulk Grain Handling Authorities throughout Australia have adopted Dryacide for structural treatment of their handling, transport and storage facilities and/or grain protection.
Australia's warm summer climate and mild winters create ideal conditions for the buildup of insect numbers. Dryacide has proven to be very effective despite such high infestation pressure.
And cost?
When treating food commodities such as wheat, rice, corn and legumes, Dryacide treatment at a rate of 1kg/tonne, costs no more than chemical insecticide treatments.
As a structural treatment, considerable cost savings are achieved. With a dust application rate of 2g/m2, the treatment cost is only about 8% of that of chemical sprays. When sprayed on as a water-based slurry at 6g/m2 (dry basis), the cost is still less than half the cost of chemicals. And unlike chemical sprays, which degrade very quickly in warm summer conditions, the dust remains effective for at least one year.
Treatment of Stored Grain

Long-term protection is obtained by treatment of grain at a rate of 1 kg Dryacide per tonne. Any powder dosing appliance can be used. The dust is added into a moving stream of the grain at a steady rate to ensure uniform distribution. Typical dosing points are auger hoppers, belt conveyors and bucket elevators. An Applicator made by Dryacide Australia and powered by a 12 volt DC battery is illustrated.

Aeration of the treated grain should be started immediately if the grain is still warm or has a moisture content too high for long-term storage. This will prevent moisture migration and quality degradation.

Blovac Unit
Dryacide requires an air stream to move it onto surfaces and into crevices. For economy and efficiency, we recommend bellows-type dusters, however, any garden duster can be used.
When applying dust to large grain stores, food warehouses or grain handling machinery, venturi blowers, such as the Blovac BV22 unit illustrated, provide the best solution.

These compressed air powered units can also be used to blow, or vacuum away grain debris from equipment and grain stores prior to treatment. Two-stroke, backpack dusters can also be employed.

In order to achieve an even coating on vertical surfaces, dust should be blown through top hatches of vertical silos. If the silo is fitted with an aeration fan, pour the pre-weighted quantity of dust into the fan suction. For horizontal storage areas and warehouses, apply from top to bottom, starting with roof structures. The operator should wear a disposable dust mask when applying dust inside stores or buildings.

This novel method of application has received a high level of acceptance in the grain industry due to its cleanliness, speed of treatment and excellent control of application rates. Application details and equipment recommendations are available.

New Dryacide developments.... in fumigated grain stores...

Dryacide dust coatings of 100g/m2 on the surface of bulk-stored grain (snow-coat treatment) has proven to be an important factor in controlled fumigation systems. The dust coating not only provides a barrier to insect infestation, it also maintains higher fumigant concentrations in the critical surface layer of grain. The small amount of Dryacide required adds little to the cost of fumigation.
Constraints on the product's use

As the insecticidal activity of the product lies in its drying properties, very high ambient humidities reduce the effectiveness of Dryacide.
It is not significant when the periods of high humidity are seasonal, e.g. a wet winter season, however, if high ambient humidifies (70% or more) prevail throughout the year, Dryacide should be tested in that situation prior to regular use.
For the same reason, treatment of damp food commodities should be avoided. Recommended moisture contents for long-term storage
protection are;

wheat, barley and oats 13% or below
sorghum, paddy rice and corn 14% or below

These moisture levels would normally be attained after routine aeration-drying after harvesting and storage.

The treatment of grain by any of the commercially available desiccant dust insecticides, including Dryacide, affects the physical properties of the grain. Flow rates are reduced and the angle of repose is increased. If all of the grain in a silo was treated, difficulties may be experienced in emptying the silo completely. However, with the top layer treatment recommended, the quantity of dust applied is very low and no effects on the handling properties or quality of the grain are experienced.
