craw rotations are the staring moment to optimise hygiene at a cultivation company . Taking care of the entire water system is for sure part of that .
The most crucial root of defilement in piddle systems is biofilm . Persistent pollution that requires a good approaching , during but certainly also after the crop rotation , say Joost Hovens from Cindro . " Every grower know how reassuring it is to have the intact company ready with a clean slate for the new plants . "
Biofilm is a layer of microorganisms , surrounded by self - develop mucus , that deposits on all surfaces in an irrigation system . Because of the mucus level around the bacterium , the bacteria are more resistant to toxic substances such as crop shelter agents .
" bacterium in the film have a high resistance and can be 10 to 1000 times more tolerant to disinfectants and toxic substance than ‘ loose ’ bacterium , " says Joost . " That make biofilm the most relentless hygiene problem in the greenhouse . "

Preventing downwardly spiralAnd that problem , will ‘ out of the blue ’ also be a lot of money , says Joost . “ On the one hand because it affects the operation and reliability of , among other matter , pump and drippers , result in irregular irrigation , malfunctions and more frequent maintenance .
And on the other hand because it affect the quality of the irrigation water system . This is because biofilm extracts crucial elements such as calcium and phosphate from the nourishing solution intended for the plant . "
afterwards , if the disinfection of the watering organisation is not in lodge , a downward spiral is menace as Joost points out . “ With pH fluctuations , the chance of fertilizer hurry increases , which in turn is a breeding ground for Modern micro-organism . In gain , biofilm pull oxygen from the irrigation piss , and this process will accelerate faster after every tearing .
The well - mean use of non - stabilized atomic number 1 peroxide to combat biofilm and harmful pathogens can cause extra problem , fit in to Cindro . “ The use of non - stabilised hydrogen hydrogen peroxide in current finish can severely fail due to the lack of constancy and strength due to the offered condition in fertilized irrigation water ( Ph , EC , composition and temperature ) .
However , there is an optimization of the O2 vividness in the water ( stronger microbiological growth ) , which means that in practice this method acting often works in opposite focusing . "
Remaining secret resistant bacterial strainsWith this fact and pragmatic experience , according to Joost , there is a direct link to resistance and the strongly decreasing effect of chemical craw protection agentive role in greenhouse gardening that can be explained easily . " From customers I often hear that the effectiveness and handling of irrigation body of water with crop tribute agent has often fall aggressively within a few season . "
In a biofilm - contaminate water organization , the use of craw auspices and insufficient disinfection will unavoidably select the strongest microorganism , say Joost . “ This micro - being can then reside in the minuscule area of the biofilm in the pee system . By using chlorine , 35 % H2O2 or acid , the biofilm can not be 100 % removed or disinfected . In a new crop , those crop protection - resistant straining are then still present , re - infect the craw , and with in effect preventive cadence are even more unmanageable to combat . "
If Cl or non - stabilized hydrogen peroxide does not process optimally in this type , is acid a solution ? " It is for inorganic dirt , but not for organic pollution , " says Joost . “ The effect on biofilm , constitutional dirt , is special . Acid can be used well in combination with silver medal - stabilise hydrogen hydrogen peroxide . "
undertake from ‘ the source’Joost advises the applications programme with Oxyl - PRO ® S , the silver - stabilized hydrogen peroxide that Cindro bring out itself . “ clock time and again I get very good results , together with the growers that I advise . It is a biocide with 50 % hydrogen peroxide as active substance . The small silver particles that are tie by a coating to the atomic number 1 hydrogen peroxide speck ensure stabilisation , selectivity ( only answer to constituent material ) and effectiveness , independent of environmental component , as opposed to normal hydrogen peroxide . “Photo : left prior , right after applying Oxyl - PRO ® S
When put on the silver stabilized H hydrogen peroxide it is important to do this as early as potential in the system . That is sometimes overlooked in practice session , according to Joost . " It is more effective to belt down 1 microorganism at the front of the system and thereby prevent biofilm than to fight 100,000 microorganisms in dirty day-to-day supply , filters or other potential sources of contamination or bushed function in the system . "
right cleaning during craw rotary motion is important for a utter disinfection , but preserve miserable concentrations of Oxyl - PRO ® S in the urine system ensures a fair water system system without biofilm throughout the entire cultivation . “ The full oscillation from biofilm to cultivation problems starts with the front of micro-organism and the right conditions .
A well mean - out dosing scheme has a direct influence on the stability of pH and accessibility of oxygen in water , in accession to the obvious diminution in micro - organisms . With this , the craw grows more uniformly with a better tooth root system , nutritional consumption and all subsequent benefits in cultivation regarding crop resistor , harvest protection , crop upkeep , labour execution and general plant , fruit and harvest time quality . And that in all conceivable irrigation system . "
