olympian interrogative from grower , that is what Ines van Marrewijk of Groen Agro Control like to focus on . If there is a solution to an issue that concerns a raiser , Ines knows how to find it . At this moment , water calibre is one of the major root , she notes . The underground piss system is a world on its own , and no matter how much we jazz about it now , there are still problems that we do not yet fully understand , says Ines . “ We need to clear up this for the future because the risk of infection of diseases remaining is difficult to eliminate . Unfortunately , you do n’t see much , literally . ”
bacterium unknownThe lookup for the right methods to evaluate bacteria in piddle requires some readying . “ Are you looking for a specific pathogenic species such as Agrobacterium or common bacteria , ” Ines explains . “ For lesson , it may require the growth of anaerobiotic bacterium at low O levels . This is not often tested and should be asked for specifically . Anaerobic and aerophilic bacteria surround themselves with a mucous secretion layer that , among other things , causes biofilm in pipes . Adding cleaning agents forbid most biofilm in the pipes . But in dead ends , connection , or crude parts , pollution and source often stay dour . change in the composition of the water can sometimes cause the increase of bacterium and yeast to suddenly ' explode ' . ”
What character of bacteria it actually is , is often not immediately clean-cut . " An object lesson : Green Agro Control distinguish certain root outgrowth ' beadroot ’ and another ’ thick solution ' . Both turn out to have a bacterial cause . Of many bacteria , it is not yet known if they are harmful to implant and root growth . We make love more by now , but not everything . The Ralstonia bacterium was also such an ' unknown factor ' when it dead appeared in roses and Anthurium , across the creation this had not previously been described as a disease in those crop . ”
DNA sequencingOne of Green Agro Control ’s new joker to boost the recognition of bacteria is Next Generation Sequencing . Through deoxyribonucleic acid sequencing different variants within a virus , bacteria or fungus can be distinguished . This way different transmitted variants of viruses can be monitor better . " Or we can do calibre control on microbial products . That direction you only confirm whether what should be there is there . For instance , the transmissible information of waste pipe water or etymon can be used to map out the microbic composing . Both useful and harmful bacteria , fungi , and virus are detected in this case . ”
By using sequencing in this room , you do not focus on just one organism , but you immediately see all the ‘ micro ’s ’ in such a sample . “ The sequence motorcar was ab initio buy for virus research , then we ’ll see what takes anteriority . For each determination , the method acting will first have to be validate in order of magnitude to obtain high - timbre results from field sampling . ”
solve problemsThe focus regarding micro at Groen Agro Control is on monitoring cultivations and also on work out problem in the industry . This mode , we preclude growth problem during fostering and cultivation through regular psychoanalysis of the urine . " If you have more than several hundreds of K of bacteria per milliliter , that is really too much , especially for vernal plants and seedlings . The bacteria get in the way of good rooting , with possible growth damage as a answer . ”
Improving resilience is also a tonality to better water system and it ’s something a caller can do . “ The sorcerous word ‘ resilience requires looking at both good and harmful micro ’s in analysis . With more extensive bacterial reckoning , you get not only the general fungus and bacteria in the water but also counts of plant life diseases and if desired also of benignant fungi in the ‘ Kiemgetal Weerbaar ’ package . "
“ We are not only looking at pathogen but also fungi and bacteria that help plant instead of process against them , such as Trichoderma . However , such a test must be done with a certain geometrical regularity to get a dependable picture of the situation . As with a UV disinfection organisation , it is not a matter of measuring once , you have to keep monitoring . ”
Water and ToBRFVLastly , Ines soar up in on the inter-group communication between water and ToBRFV or other viruses impart by water . According to her , this is still quite a blind blot for society , mainly because of the complex water system . urine is not the most dangerous agent in the spread of the horrendous tomato virus . During polish , transmission system through sap is the most life-threatening broker . “ But during harvest gyration , the peril of body of water and the drain water system is much gamey . You often have to put in 500 % effort to be 99 % virus - free . Unfortunately , you will not love if the virus has been removed for 100 % until the fresh refinement remain clean . ”
Hygiene and drawing up protocols is a specialism of Groen Agro Control and Ines also corroborate cultivator on - web site , since hygiene stay a usance answer .
