The resistant clone can easily be crossed with the commercial cultivars, so that it will be possible to breed resistant varieties which meet the demands of both the export and local markets. The high level of this resistance was confirmed by inoculating the plants with a bacterium strain, representative of the local population of the pathogen. In 1995 we have identified resistance in one Anthurium clone growing in a shade-house. dieffenbachiae) practically wiped out the whole crop.Īfter developing preventive measures to control the disease, we have initiated a breeding program for resistance to the pathogen. This flower was leading the export market until 1983 when the accidental introduction of bacterial blight ( Xanthomonas campestris pv. In the French Antilles, the development of ornamental productions in the early seventies was based on anthuriums. In this prospect, cut flowers, including anthuriums, alpinias and heliconias are considered to have a considerable potential as an export commodity. And ensure you quarantine any new plants for a while to ensure that they are uninfected.Ornamentals are of growing importance in the crop diversification policy of most Caribbean countries. Rubbing alcohol could be utilized as a sanitizing agent. Sanitize all containers and tools just before use. Fungal and bacterial anthurium diseases, including bacterial blight, root rot, stem rot. crystallinum is commonly scultivated as a houseplant, though it may be grown outdoors in warm climates. Human Res., University of Hawaii, Honolulu. There are few publications that report biocontrol studies on the ability of antagonistic bacteria strains to inhibit the pathogens of anthurium blight. Like other members of the Anthurium genus, A. The chemical control of bacterial blight on anthurium is still not successful because of the pathogenic bacteria’s serious resistance to antibiotics. Make certain that there is no standing water in places you grow your anthurium. Anthurium crystallinum, also known as crystal anthurium, is a flowering plant in the aroid family Araceae. You may easily spread blight when they're moist.įinally, appropriate sterilization is vital. Next be cautious when walking in between your plants, especially if they're wet. Be careful not to let it touch other plants as it's transported away. Second, immediately get rid of any plants that show signs of disease. This will reduce the spread of blight from an infected leaf to an uninfected one. Watering with drip irrigation will decrease the amount of water that gets on the foliage. The very first is changing how they are watered. When raising these plants in close proximity there are various things it is possible to do to decrease the transmission of blight. But if you are growing a big quantity of them, you might not have a choice but to keep them nearer together. So if you are growing these plants within your garden you want them spaced as far apart as possible. Water can transport Xanthomonas from an infected plant to an uninfected plant.Ĭertainly if you keep the plants close together, there is a higher possibility of infection than if you keep them far apart. So if you are growing andrecola you most likely don't need to worry about blight, but if you are raising andreanum, you may well wish to read on.Īppropriate anthurium care is important to hold this harmful menace at bay. Capture a web page as it appears now for use as a trusted citation in the future. Normally, andreanum are susceptible to this illness, whilst andrecola, which are andreanum amnicola hybrids are resistant against it. When an anthurium plant is contaminated it will ultimately die, if you don't manage to clear away infected leaves or flowers before the illness has progressed. A number of, but not all anthurium blossoms are vunerable to a disease known as Xanthomonas blight.
