Explanatory notes

|
At the end of harvest time
|
Implement broad acting methods to end the old crop period insect-free.
|
|
Greenhouse clearing
|
Mechanical removal of crop residue, dirt, substrate mats, foil etc. The drier the crop is, less plant juices can be spread. Use your own or disinfected crop clearing fabrics. Be careful with plant juices (leakage from containers or spread across the property etc.)! Thorough mechanical removal of all dirt is essential to perform proper cleaning and effective disinfection.

Glass cleaning (inside)
|
Cleaning of greenhouse deck and façades inside:
• Solution based on biological acids and natural plant extracts (ecological):
Greenhouse Glassclean
(practical dose for normal pollution: 5%) suited for cleaning of AR-coated glass (no action). Contact us for suitability per types of glass.
• Solution based on fluorine hydrogen:
Flusol Forte
(practical dose: 3%)
• Solution based on ammonium hydrogen difluoride:
Topcleaner
(practical dose for low level of pollution: 5 - 10%) (see
overview of glass cleaning
)
|
Greenhouse cleaning
|
After 5 - 10 minutes, spray-rinse the glass and greenhouse area with
plenty of water.
Aim: to remove all of the glass cleaner and organic material. Please note: allow the ecological cleaner to soak in for 20 minutes before it is hosed down. Heat treat the chains and crop wires.
|
creen cloth cleaning
|
For green deposits: close the cloth and spray it with
Menno ter Forte
(after one day, rinse thoroughly with water and allow to dry properly). The alternative is to use a stabilized hydrogen peroxide.
|
Cultivation gutter cleaning
|
Depending on the level of contamination: use alkaline cleaner
Hortisept Clean
1 – 3%. Use about 1500 liters/hectare and preferably apply as a foam (the foaming version is
Hortisept Clean Plus ). Within 5 minutes, rinse off with high pressure (hot) water (prevent drying of the product before it is rinsed off). Choose Menno ter Forte if many algae are present. Consult the gutter supplier about warranty provisions related to the use of Hortisept Clean. A biodegradable alternative to cleaning the gutters is
Ask the gutter supplier about the warranty conditions when using Hortisept Clean. A biodegradable alternative for cleaning the gutters is Floorclean 5 - 10%. |
Dripper system cleaning (inside)
|
Assess the degree of pollution of the dripper hoses towards the end of the cultivation period.
• Depending on the level of organic pollution, use a solution of 0.2, 0.5 of
0.7%
Huwa-San.
Fill the complete watering system with this for at least 12 hours. Then rinse the system thoroughly. Use
hydrogen peroxide strips
to check that the solution reaches the end of the system, and after rinsing, that the peroxide has been washed completely out of the system or is at the correct concentration.
• Use 3%
nitric acid
mineral contamination
(product: nitric acid 38%). Protect your own safety!

Disinfecting greenhouse areas
|
When everything is dry, start disinfecting. Preferably, lather up the surfaces. For manual foaming, use the foam sprayer and when machine foaming
with the spray truck, use the foamset.
. Also include the gutters, CO2 hoses, dripper system, duct-rail system, concrete
legs and heating ducts.
Disinfect the entire greenhouse space with Menno florades (4%). Use at least 2,500 - 3,000 liters of liquid per hectare. This product should not be rinsed off. To ensure a longest possible contact time, make sure that the space stays moist as long as possible (skylights closed, dark day, low temperature). In case of a short cultivation period (about 2 weeks), please contact our
HortiHygienz team.
Menno florades© is a plant protection product about which research is available on many pathogens in terms of concentrations and actions over time. Cucumber mosaic studies show that Menno florades inactivates this virus after one hour. Menno florades© is broad-acting, kind to fabrics (not corrosive) and can also be applied as a foam! Foam has the advantage of getting into cracks and holes, enabling a longer contact time, and that it makes treatment visible.
|
Sheeting
|
Withdraw (ground) sheet covers, pull gutter covers over the gutters and place the mats. Related to bacteria, molds and viruses, choose a ground cover for the total area. Pay extra attention to fitting it properly to concrete
paths.
|
Use fine drops to spray the mats and sheeting with stabilized hydrogen peroxide such as Huwa-San two days before planting. Huwa-San can also be applied via fog or LVM. It is very important that everything is dry (warmed) and well aired (pay attention with AC sheeting)!
|
|
Carts & Machines
|
Foam clean ductrail carts, spray robots and other equipment/machines with Hortisept Clean Plus using the
foam applicator
Plant juices and other pollutants are easily loosened by this method. As an
ecological alternative, Floorclean can also be used for this purpose. For cleaning the sorting machine, use
Nutriclean
(HACCP approved).
The foam applicator is easily connected to a water hose (3 bars). Benefits of foam application: visual control and better adhesion. Rinse the product off within 5 minutes. Prevent it from drying and prevent contact with electronics
|
Rooms
|
Cleaning of e.g. concrete (paths), floors of shed and canteen areas can also be done with the foam applicator + Menno Hortisept Clean Plus (1 - 3%). Contaminated floors can also be cleaned perfectly with the ecological product: Floorclean (1 - 5% soaking for a minimum of 10 minutes). Spray away the dirt before it dries. After this, disinfect all surfaces with Menno florades, use a foam solution as an option.
|
Small tools
|
Soak small tools such as knives and scissors for 15 minutes in a solution of Menno florades (4%). (Check the pH of the solution which works at pH 3 - 4.5)
|
Dripper hose cleaning
|
During cultivation, apply Huwa-San (practical dose for good water quality; 40 cc/m3) to combat biofilm and the spread of pathogens. Good results are achieved against the spread of crazy roots, fusarium and pythium for instance.
|
Hygiene for feet and wheels
|
Use a
Flexxo-mat
(Person PT or Transport TT) to disinfect feet and/or wheels. For compulsory disinfection of hands and feet, use a (URK) Flexxo-mat.
. Monitor the pH of Menno florades solution in the mat. This is active at a pH of 3 – 4.5. Also use
test strips.
|
Hand hygiene
|
At the entrance, place a hand basin with
Menno H
disinfectant soap for use by employees and visitors (also loosens plant sap). Repeat this process when starting work and after work breaks. Use
Enno Rapid
(hand disinfectant benzoic acid with alcohol) when entering the
greenhouse/storage area and during work practices. This is also suitable for
disinfection of small items in between times.
|
Materials
|
Also clean (Hortisept Clean Plus) & disinfect (Menno florades) materials regularly during the cultivation period. Use the foam jet, foam applicator, or manual foam pump.
|
|
Other issues
|
Make the hygiene rules clear to visitors and employees. Use a visitor registration system and provide guest overalls, over-boots and gloves. Set up a hygiene protocol, make sure that your employees are familiar with this and make one person (per location) responsible for total hygiene management.
