Yves Hendrickx, director of PPK (Research station for organic soft fruits) at Pamel

The PPK (Provinciaal Proefcentrum voor Kleinfruit, Pamel) in Belgium is an experimental station specialised in organic soft fruit production. In 2013, FresaProtect was used in a tunnel with the junebearer Candiss, an aphid sensitive strawberry variety. Releases started preventively in March just after covering the tunnels. The tubes were installed in the tunnel with the new hanging release devices to avoid predation by ants. Three species of aphids were observed in the crop (Chaetosiphon fragaefolii, Acyrtosiphon malvae and Macrosiphum euphorbiae). All were perfectly controlled and mummies from three different types (Praon volucre, Aphidius sp. and Aphelinus abdominalis) were found in the plot. No aphid damage was recorded until the end of harvest. Retrospectively, Yves Hendrickx, director of the PPK, says: « I am very pleased with the efficacy of FresaProtect. On the tested variety (Candiss), you must always fear aphid problems, even if the general pressure is low. Thanks to FresaProtect, those aphids were perfectly controlled. Without any doubt, I will continue to use FresaProtect in our strawberry trials in the future. »

Joris Volckaert

Joris Volckaert’s nursery in Nazareth (Belgium) has 0.5 hectares of heated glasshouses. Joris grows a variety of houseplant species including Kalanchoë, Muehlenbeckia, Vinca Rosea (Madagascar periwinkle), Chrysanthemum and Poinsettia. Throughout 2012, Joris used OrnaProtect to control aphids in his most important crops (Kalanchoë and Muehlenbeckia). Several species of aphid occurred in these crops in the course of the year, but OrnaProtect kept all of them under control. The main advantage of OrnaProtect, according to Joris, is that his insecticide use has been greatly reduced in comparison with previous years. Any spraying carried out was localised. He sums up his experience as follows: “I am really pleased with the spectacular effectiveness and convenience of the product, although it does require thorough scouting and a change in mentality on the part of the grower”. He adds that OrnaProtect will be his primary method of aphid control in the future.

The nursery Hanka

Hanka nursery in Kempen (Germany) grows several species of ornamental plants including white potato vine (Solanum jasminoides), Helianthus or Argyranthemum on an area of 3.4 ha of greenhouse. The company is characterized by a high interest in innovative and environmentally friendly technologies and invested, for example, in a geothermal heating and heat pumps. In 2012, Mr. Uellekes, responsible for the cultures of Solanum jasminoides, used OrnaProtect in his greenhouse of mother plants. These plants are extremely valuable as they provide cuttings for the entire production of Solanum for the company. Throughout the year, aphid attacks were well controlled and no insecticide against aphids was necessary. According to Mr. Uellekes, the system OrnaProtect is really attractive. Its use is very simple and fast. He adds: “The workers in charge of the harvest of cuttings are continuously in contact with the plants. Reducing their exposure to chemicals is one of our priorities. With OrnaProtect, we have significantly reduced the amount of insecticides used in this greenhouse compared to what we did in the past. Without any doubt, we will extend the use of OrnaProtect to other departments of our production. “

Peter Sprünken

Peter Sprünken’s nursery in Straelen-Holt (Germany) is specialized in the production of Argyranthemum and seedlings of Cyclamen. In 2012, Peter Sprünken tested OrnaProtect in heated greenhouses in over half of his operation units. Attacks from the foxglove aphid and from the peach potato aphid on Argyranthemum were well controlled in the spring as were those of the cotton aphid on Cyclamen later in the season. In the greenhouse under conventional pest management, two chemical treatments were necessary to control aphids. Retrospectively, Mr. Sprünken said: “OrnaProtect is a really good concept. As I produce different plant species, several species of aphids can cause problems. This year, thanks to OrnaProtect, aphids, whatever the species, were no longer a concern. “

The municipal greenhouses of Roubaix

The city of Roubaix is fully autonomous for its plant production for annual and biennial flowering of public spaces. In its 4000 m² of greenhouses, it produces a large number of different species of ornamental plants. Since 2007, the fight against pests entirely follows the integrated pest management (IPM) guidelines. In this context, OrnaProtect was tested in 2012 on the entire surface of the municipal greenhouses. On the production of summer flowers (Ipomea, Ageratum, Argyranthemum, Swiss chard, Rudbeckia …), no insecticide treatment was needed. For the production of autumn flowers (pansy, dusty miller, common daisies …), OrnaProtect has reduced insecticide use of several generalized treatments usually to a single spot treatment. According to the site manager, Isabelle Chansellé-Becue, the results are really satisfactory. In addition to efficacy, she praises ease of use and the working comfort that it generates at the staff level. Without hesitation, Mrs. Chansellé-Bécue adds: “We had the chance to be the first municipality to test OrnaProtect and we will continue to use it in the future. It is a product that I also recommend to my colleagues for the benefits it provides and for its effectiveness. “

Mr Albert Bernard – Organic vegetable grower

Mr Bernard grows organic vegetables in Louvil (Nord-Pas-de-Calais, France). In 2012, he tested VerdaProtect in his tunnels of eggplants, tomatoes and peppers. Throughout the season (May to October), several species of aphids appeared such as peach potato aphid (Myzus persicae), foxglove aphid (Aulacorthum solani) or potato aphid (Macrosiphum euphorbiae), and they were all perfectly controlled. After this first season of use, Mr. Bernard said: “I am very satisfied with the effectiveness of VerdaProtect. Especially in eggplants, I saw a difference compared to previous years, when aphids reduced yield and obliged me to wash the fruits. VerdaProtect is very easy to use and really convinced me. “

Managing Director Andreas Pellens – The hydrangea nursery Pellens GmbH in Geldern

The hydrangea nursery Pellens GmbH in Geldern, Germany, produces annually 1.500.000
hortensia, out of this 80% as raw material. The 30 coworkers of the company care about more than 40 different varieties, which grow up on 17 hectares.

Managing director Andreas Pellens used OrnaProtect in the greenhouse from January to October 2011. During the cooler season the green-spotted potato aphid (Aulacorthum solani) was observed. This aphid species has been controled by OrnaProtect, as were all other different aphid species appearing later in the season.

Retrospectively on the year Mr. Pellens says: „The application of OrnaProtect is simple and can be accomplished – contrary to chemical treatments – by untrained personnel. By using a cocktail of different aphid ennemies I save labor and thus expenditures for monitoring and for aphid identification, which so far was necessary for the use of parasitoid wasps. For me, OrnaProtect is a convincing concept. “

Managing director Wolfgang Ripkens used OrnaProtect in cyclamen

The nursery of ornamental plants Wolfgang Ripkens in Straelen, Germany, produces, among other plants, on several thousand square meters Cyclamen. Since more than a decade, Mr Ripkens uses beneficial insects for plant protection under integrated pest management. This approach has been convincing, because it does not result in the development of resistance as it is observed by using chemical pesticides, and because it strongly decreases the handling of chemicals by the workers.

Managing director Wolfgang Ripkens used OrnaProtect in the greenhouse from end of March until mid-October 2011. During the crop season, some individuals of the green-spotted potato aphid (Aulacorthum solani) were observed sporadically. This aphid species has the characteristic to overwinter in form of eggs. However, it has been controlled by OrnaProtect, as were all other different aphid species trying to establish in the crop.

Retrospectively on the year Mr. Ripkens says: „The application of OrnaProtect is simple and fast, I save about 60% of labor time. Throughout the season, all appearing aphids were perfectly controlled.
Moreover, the use of a mix of six different parasitoid species gives me more security, and I do not need to invest anymore in the difficult task of aphid identification. The simplicity of using OrnaProtect convinced me.”

Bernd Tönneßen – Organic grower

The organic grower Bernd Tönneßen (member of the Bioland association) in Bornheim, Germany, used VerdaProtect in 2011 in a tunnel culture of sweet pepper. During the entire crop season (April through September) and even at temperatures reaching 42 °C, all occuring aphids were reliably controlled.

A comparative strategy with commonly used beneficials was equally able to control the aphid populations, the deployment required however a substantially higher expenditure on labor (installation and crop monitoring).

Retrospectively on the season Mr. Tönneßen says: „VerdaProtect is the means of choice, it is easy and fast in application, my crop is well armed against aphids, and I have to invest less – in terms of money and time. Without any doubt, I will use this concept in the future for the protection of my crops.”
