Alzogur®
Product Group: Biocide
Alzogur® is a product for the treatment of liquid manure in pigsties. It destroys the infective agent of dysentery (pig diarrhoea), it fights the larvae of flies and also reduces the noxious gas released from liquid manure. After the spreading of liquid manure on the fields Alzogur® becomes available to the plants as a nitrogen-rich nutrient.
Use biocides safely. Always read the labelling and the product information before use.
No more flies and dysentery in pig farming!
The liquid manure underneath slatted floors holds numerous risks for successful pig farming: not only are many pathogens able to survive in the manure and remain viable and infectious for several months, it is also an ideal breeding ground for flies. Flies are not only a nuisance for the animals, they also transmit dangerous pathogens from the slurry channel.
However, Alzogur® is at hand to eradicate fly larvae (Musca domestica) and dysentery (B. hyodysenteriae) from liquid manure, creating a beneficial climate in the pig house and provides sustaining protection against flies and dysentery.

What is Alzogur®
Alzogur® is a biocide for treating liquid manure in pig houses. It is used to eradicate fly larvae with sustaining effect and to kill dysentery pathogens in the slurry.
In connection with dysentery, Alzogur® plays an important role in both the decontamination of affected farms and prophylactic treatment.
Once slurry treated with Alzogur® has been spread on the fields, Alzogur® is converted into forms of nitrogen that are readily available to plants and thus acts as an effective plant nutrient.
Alzogur® is a biocide and must therefore be stored in its original container, which must be kept away from direct sunlight and stored at temperatures not exceeding 20°C. The container must be kept out of reach of children and away from food, beverages and animal feeds.
Alzogur® has a limited shelf life; please refer to the expiry date shown on the container.
Always comply with the information provided in our safety data sheet!

- Alzogur® is a biocide and must therefore not be applied via a high-pressure cleaner or backpack sprayer, as this may result in harmful aerosols.
- Users must not consume alcohol before, during and 24 hours after handling and applying Alzogur®.
- The intake of Alzogur® may be harmful to health, and any unnecessary contact with this biocide must therefore be avoided.
- Only persons concerned with applying Alzogur® may access the pig house during Alzogur® application. Others, in particular children, and pets such as dogs or cats must not enter the pig house.
- Never use Alzogur® in stocked or partially stocked pig houses.
Use and apply with the utmost caution and wear appropriate personal protective equipment:
- ProChem® IC protective suit (or equivalent type of protective suit as per EN 14605)
- Rubber boots (EN 13832)
- Protective gloves (EN 374)
- Tightly sealing goggles
Always comply with the information provided in our safety data sheet!
Effect
Alzogur® is a biocide for treating liquid manure. Alzogur® reliably controls fly larvae in their breeding grounds, that is in liquid manure. This effectively eradicates these disease carriers and contributes to healthy pig house hygiene.
Alzogur® is particularly important in combatting swine dysentery, as it eliminates the pathogen Brachyspira hyodysenteriae from liquid manure and thus breaks the infectious cycle.
The active substance of Alzogur® gradually decomposes in liquid manure over a period of several months, but once the manure has been spread on the field, it is broken down completely into nitrogen compounds readily available to plants within a matter of days.
Dysentery? No, thanks!
Dysentery pathogens (Brachyspira hyodysenteriae) are excreted with faeces and can remain viable and infectious for up to 8 months in liquid manure, continuing to spread infections again and again. Slurry accumulating underneath slatted floors is an ideal breeding ground for flies, which transmit the pathogens back to the pigs. A comprehensive approach to pig house hygiene is therefore essential if the fight against dysentery is to have a lasting effect!
- Optimise farming conditions, pig house hygiene and climate.
- Fight rats, mice and flies, all of which spread dysentery.
- Use Alzogur® to eliminate dysentery pathogens and fly larvae in liquid manure.
Alzogur® has a long track record as a reliable agent that effectively combats dysentery and fly larvae. Alzogur® yields reliable, sustaining effects and is easy to apply.
Alzogur® effectively combats flies (Musca domestica) before they even fly!
Flies (Musca domestica) are an unpleasant nuisance in pig houses, both for humans working there, and for animals. Pesky flies cause restlessness among animals, which in turn results in poorer performance or even abnormal animal behaviour, including savaging behaviours, which can occur due to excessive numbers of flies. But that is not all: flies carry and transmit a variety of infectious diseases (Hellwig, 2000).
Infectious diseases transmitted by flies:
| Disease | Agent | Clinical picture |
|---|---|---|
| Swine erysipelas | Bacteria | Abortions and stillbirths, among others |
| Leptospirosis | Bacteria | Impaired fertility |
| Pasteurellosis | Bacteria | Respiratory tract infections |
| Foot-and-mouth disease | Viruses | Death, among others |
| Swine fever | Viruses | unspecific |
| Salmonellosis | Bacteria | Diarrhoea, among others |
E. coli infections | Bacteria | Diarrhoea, among others |
| Coccidiosis | Single-cell organisms | Diarrhoea |
| Nematode infections | Parasites | Underperformance |
| Aujeszky´s disease | Viruses | Unspecific |
| Brucellosis | Bacteria | Irregular return to oestrus, abortions |
| Dysentery | Bacteria | Bloody diarrhoea |
(Hellwig, 2000)
Application
The correct application of Alzogur® is essential not only for successful treatment, but also for the safety of humans and animals.
It is therefore imperative that you read the directions for use on the packaging label.
IMPORTANT: Always wear personal protective equipment when preparing and spreading the Alzogur® solution and when rinsing off Alzogur®!
1. Remove all animals from the pig house
Animals must not come into contact with Alzogur® at any time, and it is therefore imperative that all animals are cleared from the pig house prior to application. Ensure that pets such as cats or dogs are also kept out of the pig house while Alzogur® is being applied.
2. Thoroughly clean the pig house
Clean the pig house with water. Thoroughly clean slatted floors with a high-pressure cleaner to ensure that surfaces are entirely free from manure and feed residue. Break up surface crusts in slurry channels and drain liquid manure as far as possible.
3. Prepare the Alzogur® solution
Alzogur® is always diluted with water for use (= in-use solution).
The actual dilution rate depends on the volume of slurry residue present and the purpose of treatment (i.e. combating flies or dysentery pathogens).
(For details on Alzogur® application rates and dilution ratios see the packaging label or refer to the “Application rates” section.)
The product should be diluted by measuring the required amount of Alzogur® into a beaker, transferring the product into a watering can and then carefully adding water to fill the can.
When using the specially designed Alzogur® dispenser cart to apply the product, prepare the in-use solution directly in the dispenser cart tank.
Hose any spilled Alzogur® residues into the slurry channel before it dries.
4. Apply Alzogur®
Alzogur® is applied to the damp pig house floor immediately after cleaning. If the floor has dried, the surface must be dampened again.
Apply the Alzogur® in-use solution evenly to slatted floors in coarse droplets, using a watering can or the lance on the Alzogur® dispenser cart.
NEVER USE high-pressure cleaners, backpack sprayers or similar devices. The solution must be applied in coarse droplets, without pressure, to prevent aerosol formation and thus ensure its safe application.
Do not treat walls or troughs. Alzogur® is stained blue to allow treated surfaces to be easily identified.
Alzogur® is only effective if it is applied in sufficient concentration. The solution must be evenly distributed to be optimally effective.
5. Rinse slatted floors
Leave the treated surfaces briefly, about 30-60 minutes, being careful not to allow the in-use solution to dry, then rinse the solution into the slurry channel with a hose, applying NO PRESSURE. NEVER use a high-pressure cleaner! Rinse until all traces of blue have disappeared.
6. Leave the pig house to dry
After rinsing, leave the pig house to dry before disinfecting surfaces as usual.
7. Stock animals
The pig house can then be safely stocked with animals.
To combat flies (Musca domestica):
1 litre Alzogur® per m³ slurry residue
To combat dysentery (B. hyodysenteriae) and flies (Musca domestica):
3 litres Alzogur® per m³ slurry residue
Sample calculation:
Rate of application: 1 litre Alzogur® per m³ slurry residue
Combine the following quantities of Alzogur® and water per 10 l watering can for the given slurry levels. Always 10 l of in-use solution should be applied per 10 m² of slatted floor.
| Slurry depth in the channel | Alzogur® | Water | In-use solution per 10 m2 |
|---|---|---|---|
| 5 cm | 0.5 litres | 9.5 litres | 10 litres |
| 10 cm | 1.0 litres | 9 litres | 10 litres |
The following steps will help ensure that you apply Alzogur® with optimum success.
1. Break up surface crusts.
Surface crusts and any solids protruding from the slurry surface must be broken up; otherwise the active substance in ALZOGUR® will be distributed unevenly in the slurry channel, which will reduce the efficacy of the product. If the surface crust cannot be broken up completely, fill the slurry channel with enough water to create an even surface.
2. Establish an even slurry surface in the slurry channel.
Drain the slurry channel as far as possible, ensuring that the channel floor remains fully covered with liquid. Ensure that the slurry level is even; check by verifying the slurry depth at various sites in the channel using a folding rule. Check the channel corners in particular, and any areas underneath feeding troughs, where feed residue tends to accumulate.
3. Calculate the correct application rate.
It is essential that the correct quantity of Alzogur® is applied per m³ of treated slurry; this is why it is important to verify the slurry depth carefully with a folding rule rather than estimating the volume of slurry residue.
4. Dilute Alzogur® with water.
Dilute Alzogur® sufficiently with water according to application rates and apply 10 l of the in-use solution evenly per 10 m² slatted floor.
5. Treat slurry residue completely, hose any maggots into the manure.
Treat interconnected slurry channels at the same time, even if the channel runs underneath several sections. Any maggots remaining on pig house surfaces between the wall and pens or in partitions must be hosed into the slurry.
6. Combatting adult flies.
It is essential that any adult flies remaining in the pig house after cleaning are killed with a surface-active biocide immediately after Alzogur® is applied.
Use the recently developed dispenser cart for optimum efficiency in applying Alzogur®. The dispenser cart allows Alzogur® to be applied easily, quickly and safely!
Preparation of the Alzogur® in-use solution for dispenser cart application:
- Draw the required volume of Alzogur® from the can or drum into the dispensing cart.
- Fill the dispensing cart with water.
Dosing table for dispensing cart application:
Application rate: 1 litre Alzogur® per m³ slurry residue
Use the following volumes of ALZOGUR® and water in the dispensing cart (200 l) for the slurry depths indicated below:
| Slurry depth in the channel | Alzogur® | Water | In-use solution for 200 m² |
|---|---|---|---|
| 5 cm | 10 litres | 190 litres | 200 litres |
| 10 cm | 20 litres | 180 litres | 200 litres |
| Slurry depth in the channel | Alzogur® | Water | In-use solution for 200 m² |
|---|---|---|---|
| 5 cm | 30 litres | 170 litres | 200 litres |
| 10 cm | 60 litres | 140 litres | 200 litres |

As long as Alzogur® has been appropriately applied in the pig house, the slurry can be safely used in biogas plants.
Effect of Alzogur® on bacteria:
- Due to its biocidal properties, Alzogur® initially inhibits bacterial activity of liquid manure when used at the suggested ratio (1-3 litres per m3 slurry residue).
- However, Alzogur® only inhibits the activity of certain bacteria such as dysentery pathogens, while many other bacteria are virtually unaffected by the product.
What is the maximum Alzogur® concentration that may be present in fermenter before gas production is impaired?
Studies conducted by Hohenheim University have shown that:
Gas production is not impaired with Alzogur® active substance concentrations of 0.01% and below in the fermentation substrate.
These concentrations are not expected to occur in biogas plants due to dilution and break down of the active substance between application and the use of slurry in the fermenter.
Why is it that Alzogur® liquid manure does not normally cause any problems in the fermenter?
- When applying Alzogur®, only the slurry residue remaining underneath slatted floors is treated, which is only a relatively small volume.
- Within a few weeks of application, decomposition and dilution cause the concentration of active agents to be reduced to a level that ensures that the slurry can be safely fed into biogas plants.
The Alzogur® concentration in the slurry continues to decrease until fermentation due to the following processes:
- Bacterial decomposition in the slurry
- Dilution by fresh manure
- Possible combination with untreated liquid manure in the preliminary or elevated tank
- Combination with other substrate before or during transfer to the fermenter
- Substantial dilution in case of continuous operation, where only a small portion of fresh substrate (about 2%) reaches the fermenter every day
- Faster decomposition in the fermenter due to higher temperatures and intensive bacterial action
