    Application of a mobile unit for discharge water purification is one of four options to apply to the purification obligation per 1-1-2018. Depending on the amount of discharge, future water strategy and investment options, mobile purification can be an interesting option. The amount of discharge water varies with crop, irrigation strategy and quality of the irrigation water and is between 122 and 3.340 m3/ha/year for surveyed companies. About 65% of greenhouse companies discharges
    Vervolgonderzoek emissiearme Lisianthus

    Lisianthus growers look for methods to minimise the emission of nutrients, crop protection chemicals and CO2. In 2014 and 2015, nine crops with Lisianthus have been tested at the Delphy Improvement Centre. This report describes the four trials that have been carried out in the extended research in 2016. With this extension, a distinction was made between different substrates and intensities of assimilation lighting. In addition to knowledge about light use efficiency, water use, heat use, substrate differences and growth development, these extra crop cycles have brought to light that growing Lisianthus on substrate gives a less resilient plant against soil fungi than was experienced during the first crop cycles.

    Within a project Sustainable control strategies Wageningen University & Research Greenhouse Horticulture literature screening to develop an integrated pest management strategy to control airborne fungi. This project was funded by the former Dutch Horticultural Production Board and accompanied by the Dutch growers association, LTO Glaskracht Nederland. In 2016 two greenhouse trials were performed with pot tomato, Petunia and pot gerbera. Additionally, a greenhouse test was performed at a commercial greenhouse with pot gerbera. Goal was to test the side effects of synthetic elicitors which stimulate systemic acquired resistance against biotrophic fungi on disease resistance against nectrotrophic fungi like Botrytis. A commercially available synthetic elicitor, Fado (Nufarm) was able to reduce the Botrytis infection in pot tomato and in flowers of pot gerbera. Effectivity was supported by a combined treatment with Jiffy mineral (soil addition) and Serenade. Two experimental products of BASF and Nufarm were effective in reducing Botrytis in pot gerbera. Botrytis infection was not only related to light and relative humidity, but was also correlated with nutrients and chlorophyll content. Based on this knowledge, prediction models for Botrytis can be improved.

    Within this project, two new methods of the control of pathogens were investigated. New methods are: a. use of local bacteria that are isolated from soils or growing substrates; and b. bacteria that are present within the plant. By using local antagonists, already present in growing substrates or within plants in the greenhouse, the chance is higher that antagonist can be successfully used against local pathogens. Bacteria that were isolated from soil of growers were assessed on their antagonistic potential in lab trials against Pythium ultimum, Meloidogyne spp. and Rhizobium rhizogenes and Fusarium solani and F. oxysporum. Finally, the effect of antagonists against Pythium and Meloidogyne was evaluated in pot trials in the greenhouse. All antagonists diminished brown colourization symptoms in stems caused by Pythium. Alcaligenues sp., Bacillus sp. en two unidentified species diminished root damage and Alcaligenues sp. as well as Bacillus also reduced also the number of offspring of Meloidogyne spp. within the roots. The use of local microorganisms offers a sustainable-, new solution to control pathogens. In this study, it was shown that Proteinase inhibitor 2 (PINII), Glucanase (LeGluB) and Chitinase (LeChi3) can be used in tomato to investigate the influence of antagonists or endophytes on the plant defence.

    To apply to the Dutch generic obligation to purify discharge water, each horticultural company needs to treat it’s discharge water with a technology that removes 95% of plant protection products. This report shows the process that growers need to go through to make a good choice for a purification technology: mapping of water flows, decrease the amount of discharge water, determine the strategy to apply to the generic obligation and make a choice for a purification technology. For a cucumber production company and a company that combines vegetable plant propagation and growth of potted plants this process is followed. A design for a purification system is developed and built for a semi-practice scale cucumber and sweet pepper production system. In the semi-practice scale and the cucumber production company, an ozone installation (Agrozone) is chosen, either to disinfect drain water and eventually purify discharge water. At the propagation company, an Opticlear Diamond (WaterIQ) is chosen to disinfect the drain water and eventually purify discharge water. For both installations the purification efficacy is measured. In the second part of the project the practical format for the generic obligation for discharge water purification is elaborated.
    Grasklaverteelt motor voor samenwerking en klimaatadaptatie : 'climatecafe' evalueert samenwerking akkerbouw- en veeteeltbedrijven

    Het wordt natter en warmer in Nederland voorspelt het KNMI. Is de biologische boer bezig met deze verandering? Dat valt wel mee. Er wordt gewerkt aan een goede bodemkwaliteit en structuur. Dat draagt bij aan het aanpassingsvermogen aan een veranderend klimaat (‘adaptatie’). Grasklaver als rustgewas helpt de akkerbouwer daarbij, zo blijkt ook uit modelberekeningen.

    Closing of the water cycle is required in the forcing of tulips. For growers it is important to know if and how they can eliminate pathogens at an adequate way and which equipment is most suitable to break down plant protection products from waste water. Now participating growers have various equipment for full or partly disinfection. It is recommended to start with good pre-filtration methods to eliminate pathogens which can be fully achieved with UV and ozone, while products such as hydrogen peroxide with additives or chlorite products can be used for an after-effect in the pipe work. Phenolic compounds, released by the roots, can be eliminated with oxidising methods. However efficacy has not been investigated. Purification of discharge water, before entering the waste ditch, will be obliged. New, certified, equipment will come on the market soon. Reuse of discharge water, after pre-fi ltration and disinfection, is also an option.
    Gebruik van groene middelen : Inventarisatie laanboomkwekerij

    In de laanboomteelt in de regio Opheusden wordt al jarenlang gewerkt aan verduurzaming van de teeltmethoden. Het verantwoord toepassen van gewasbeschermingsmiddelen is daarvan een belangrijk onderdeel. Door strengere regelgeving wordt het chemische middelenpakket steeds verder beperkt en komen boomkwekers in toenemende mate voor knelpunten te staan. Uit oriënterende gesprekken in de regio blijkt dat een deel van de boomkwekerijbedrijven zich inmiddels toelegt op het gebruik van groene middelen om zo de afhankelijkheid van chemische middelen te verkleinen. Volgens de definitie van het Ctgb zijn dit gewasbeschermingsmiddelen van natuurlijke oorsprong (planten, dieren, microorganismen) met een laag risico voor mens, dier, milieu en niet-doelorganismen. In dit project wordt geïnventariseerd wat de mate van gebruik is van groene middelen door laanboomkwekers in de regio Rivierenland én wat hun ervaringen zijn met deze middelen. De uitkomst kan de sector in de regio benutten om de kennisuitwisseling voor duurzaam telen te bevorderen, zowel tussen kwekers als naar de burgers.
