As part of the vegIMPACT project a laboratory test in the Netherlands was done with potato (Solanum tuberosum) var. Bintje and onion (Allium cepa) var. Sturon. In both crops mancozeb was sprayed with and without the adjuvants Bond and Indostick. In both crops these three treatments were applied with high and low spray volumes. After spraying, rain was simulated (0.5, 3 or 6 hours after spraying and a control without rain) to test the sticker properties. After five days, plant leaves were analysed on mancozeb residue. Five days after spraying the potato plants were inoculated with Phytophthora infestans and onions with Peronospora destructor. Subsequently, disease symptoms were observed and visually rated as percentage of infected leaves. In potato lower mancozeb residue levels were measured at high spray volumes. Under dry conditions the effect of adjuvant on mancozeb residue in potato was limited. In onion the spreader characteristics of the adjuvants resulted in higher mancozeb residue concentrations than without adjuvant. The impact of rain simulation was much bigger than the impact of adjuvant on mancozeb residue and late blight incidence. Therefore, it is not recommended to spray when rain is expected within the same day as spraying. With rain simulation in both onion and potato more mancozeb residue was present when using the adjuvant Bond than when spraying mancozeb without an adjuvant. However, also with Bond after rain simulation high amounts of mancozeb were washed off. Mancozeb with Bond in potato resulted in less late blight incidence than with spraying mancozeb without adjuvants. Overall the adjuvant Bond performed better than Indostick in terms of mancozeb retention on both potato and onion leaves . Indostick had good spreading properties that under dry conditions resulted in higher mancozeb residue levels in onion. Under rainy conditions the effect of Indostick on mancozeb residues was not or only slightly better than mancozeb without adjuvant.

Food security is one of the main issues in Ethiopia. Large amounts of money are spent on food security programs set up by federal- and regional governments and other organisations. Decisionmakers, as well as researchers, share a dependency upon reliable data on soils, water and crops. The authors of this report believe that the data from the Ethiopian soil laboratories are not reliable enough for decision-making purposes. Ethiopian laboratories need to improve their analytical services. The main problems concern the organisational set-up, and not merely a lack of budgets for facilities. Apart from organisational problems, managerial-, human resources-, technical-, instrumental- and supply issues were identified.

Nationale Referentie Laboratoria (NRL’s) vormen een onderdeel van het stelsel voor controle en handhaving van EU wet- en regelgeving op het gebied van veiligheid van voedsel en diervoeders. RIKILT is aangewezen als NRL voor twaalf onderzoekdomeinen. Taken van een NRL zijn afhankelijk van het onderzoekdomein. In dit rapport wordt een overzicht gegeven van de activiteiten in 2014 van alle NRL’s van RIKILT. Dit zijn de NRL’s voor dioxines en PCB’s, pesticiden in dierlijke producten, mycotoxinen, zware metalen, polycyclische aromatische koolwaterstoffen (PAK’s), mariene biotoxinen, stoffen en producten gerelateerd aan Richtlijn 96/23/EG, genetisch gemodificeerde organismen in voedsel en voeders, dierlijke eiwitten, diervoederadditieven, melk- en melkproducten en watergehalte pluimveevlees.

In the autumn of 2014 a proficiency test for allergens in baby cereal was organized by RIKILT, Wageningen UR. This PT-test enabled laboratories to evaluate their competence for the analysis of allergens in baby cereal. Both quantitative and qualitative methods were accepted. The proficiency test was carried out according to ISO/IEC 17043, however this specific test is not part of the accreditation.

The BIO-SEA® Ballast Water Treatment System (BWTS) was tested at the IMARES land-based test facility. General goal of the tests was to compare two different brands of filter and to test the filter efficiency of finer mesh sizes of each brand. The filters were tested in combination with a ‘one-shot UVtreatment’ (ballasting and deballasting the same day) in order to evaluate the effect of the filters on the overall treatment efficacy.
