Anthurium and Xanthomonas
Found in:29 November 2022
A very dangerous disease caused by the bacterium Xanthomonas (X) can occur in Anthurium. It usually involves the bacterium Xanthomonas phaseoli pv. Dieffenbachiae (Xpd). The Xanthomonas, which is harmful to Anthurium, can occur in many different strains (types). There are mild variants where only a limited part of the range gets affected, but there are also aggressive types that spread widely and quickly.
Energy saving opportunities in Anthurium
Found in:12 September 2022
In view of the current energy situation, the use of heating and lighting in cultivation must be minimized. This offers opportunities for Anthurium for which specific conditions must be met.
The guiding principle for a healthy Anthurium crop is to avoid major fluctuations. When the balance between root and plant activity is right, a quality product can be grown in an energy-friendly way. This article discusses the factors that can be taken into consideration.
Silver lining in the approach to Tobacco Thrips
Found in:23 June 2022
Thrips causes considerable damage to plants and are difficult to control. Therefore, it is important to be alert for signs of Tobacco thrips so that prompt action can be taken. This edition focuses on the approach to Tobacco thrips (Thrips parvispinus).
A more effective approach to thrips through proper identification
Found in:23 May 2022
Identifying thrips is difficult, because both the different thrips species and the larvae are often very similar. A diagnosis is difficult, sometimes insufficiently reliable and often takes (too) long. Then the question arose for us: ‘How can we do this faster and better?’ We started to work on this question.

Substrate Anthurium cut flowers
Found in:4 November 2021
Anthurium cultivation generally involves the use of what are known as ‘airy substrates’. These are substrates that contain a lot of air, even in humid conditions. The quality of a plant depends on the correct use of the right substrate with the right properties. Read more about the substrate of Anthurium cut flowers.
Threat monitoring
Found in:6 July 2021
In the cultivation of both Anthurium and Phalaenopsis, it is important to continuously monitor the cultivation. Growers strive to keep cultivation conditions constant throughout the year. Unfortunately, they have to deal with many different external influences. Besides insects, fungi and bacteria, inaccuracies in pH/EC, nutrient composition, starting water, etc. can have a major impact on the crop.
Monitoring van bedreigingen

Thrips (in general)
Found in:24 February 2021
Thrips are a growing problem in the cultivation of Anthuriums and Phalaenopsis. Whereas thrips were rare in Phalaenopsis a few years ago, they have become increasingly common in recent years. There is an increasing number of exotic thrips species, which require a specialist approach. The variety of chemical agents, on the other hand, is increasingly limited.
Bestrijden voor een ‘kritische consument’
Found in:8 December 2015
Anthurium en phalaenopsis zijn teelten waar relatief weinig in hoeft te worden bestreden. Gelukkig maar, want overheid, organisaties en consumenten worden steeds kritischer als het gaat om bestrijdingsmiddelen.
Thrips in Anthurium
Found in:2 March 2021
Worldwide, we are seeing a significant increase in thrips pressure in both cut flowers and pot Anthurium. In cut Anthurium, thrips can establish themselves in the crop and return every year to more or less the same places. This is often the case with thrips that are present on the leaves.
pH in Anthurium and phalaenopsis
Found in:5 November 2020
In the Anthurium and Phalaenopsis cultivation, a lot of attention is paid to acidity. The acidity, or pH value is important for the absorption of several nutritional elements.
Energy balance
Found in:13 July 2020
When it comes to plant growth, we tend to immediately think of all the biological and physiological processes that take place during the growth of the plant. The fact that plant growth is actually mostly about physics is sometimes overlooked. Growth depends to a large extent on the energy balance of the crop.
Physiological abnormalities
Found in:10 March 2020
Growers are increasingly demanding more from their crops: better quality, less labour, more yield. A prerequisite for this is optimum cultivation control. Having sufficient knowledge of how the plant functions, and thus of plant physiology, is essential for this. How do plants function and how do they react to changes in environmental factors?
New experiences and insights in nutrition strategy
Found in:23 July 2019
The optimum amount (and therefore the proportions between the elements) of nutrients in a solution differs according to each crop and often also its cultivation phase. Over the years, the ideal composition of elements in nutrient solutions changes due to new insights, practical experiences and the results of different studies. This article discusses new insights and experiences for each crop.
