After infection, fungal spores of Verticillium nonalfalfae are distributed in the sap stream. Germinated spores in turn form local mycelium aggregations, which release enzymes and toxins into the water transport tissue. This leads to withering and subsequent decay of the plants. The first symptoms can occur 4 - 6 weeks after inoculation if applied early and under favourable conditions. In the case of large trees, the effect is usually only visible in the following year. The fungus can also spread into neighbouring shoots if they are connected to an infected tree by root runners.

biohelp - biologischer Pflanzenschutz Nützlingsproduktions-, Handels- und Beratungs-GmbH collects, processes and uses your personal data only with your consent, order or order for the purposes agreed with you, or if there is any other legal basis in accordance with the DSGVO; this in compliance with data protection and civil law provisions. Only such personal data will be collected which are necessary for the execution and processing of our services or which you have voluntarily made available to us. Personal data are in particular data that contain individual details about personal or factual circumstances, such as name, address, e-mail address, telephone number, date of birth, age, gender, social security number.
2. information and deletion
As a customer, business partner or generally as a data subject, you have the right at any time - subject to compliance with any statutory obligation of confidentiality - to obtain information about your stored personal data, its origin and recipient and the purpose of the data processing as well as the right to correction, data transmission, objection, restriction of processing as well as blocking or deletion of incorrect or inadmissibly processed data. Insofar as changes occur to your personal data, you must inform us of these. You have the right to revoke your consent to the use of your personal data at any time. Your request for information, deletion, correction, objection and/or data transmission, in the latter case, provided that this does not cause a disproportionate effort, can be directed to the address stated in point 10 of this declaration or to the biohelp data coordinator. If you are of the opinion that the processing of your personal data by us violates the applicable data protection law or that your data protection claims have been violated in any other way, you have the possibility of complaining to the responsible supervisory authority. In Austria, the data protection authority is responsible for this.
3. data security
The protection of your personal data takes place through appropriate organisational and technical precautions. These precautions relate in particular to protection against unauthorised, illegal or accidental access, processing, loss, use and manipulation. Irrespective of our efforts to maintain a reasonably high level of due diligence at all times, it cannot be ruled out that information that you disclose to us via the Internet may be viewed and used by other persons. Please note that we therefore accept no liability whatsoever for the disclosure of information due to errors in data transmission not caused by us and/or unauthorised access by third parties (e.g. hacking of email accounts or telephone, interception of faxes, etc.)
4. use of the data
We will not process the data provided to us for purposes other than those covered by the contract or your order and by your consent or otherwise by any provision in accordance with the DSGVO. Excluded from this is the use for statistical purposes, provided that the data provided has been anonymized. Within the scope of informing our customers, we will only send you e-mails if you have expressly provided us with your e-mail address.
5. transmission of data to third parties
It may also be necessary to pass on your data to third parties in the context of customer service and fulfilment of the purpose of the contract. Your data will be forwarded exclusively on the basis of the DSGVO. Some of the above-mentioned recipients of your personal data are located outside your country or process your personal data there. However, biohelp only transfers your personal data to countries for which the EU Commission has decided that they have an adequate level of data protection and we take measures to ensure that all recipients have an adequate level of data protection, for which we conclude standard contractual clauses (2010/87/EC and/or 2004/915/EC). Your data will not be sold to third parties.
6. disclosure of data breakdowns
We make every effort to ensure that data breakdowns are detected at an early stage and, if necessary, reported immediately to you or the responsible supervisory authority, taking into account the respective data categories affected.
7. storage of data
We will not store data for longer than is necessary to fulfil our contractual or legal obligations, for archiving purposes in the public interest and to ward off any liability claims.
8. server log files
In order to optimize this website with regard to system performance, user-friendliness and the provision of useful information about our services, the provider of the website automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. This includes your Internet protocol address (IP address), browser and language settings, operating system, referrer URL, your Internet service provider and date/time. These data will not be merged with personal data sources. Server log files exist for about 2 weeks and are then automatically deleted. We reserve the right to subsequently check this data if we become aware of concrete indications of illegal use.
9. our contact data
