As the Kenyan flower sector continues to grow in world markets, consumer demand and subsequently trade requirements are being demanded and increasingly differentiated in various markets. Demand for sustainably produced and distributed products is rising, as a result Amiran has sought for the best quality of products; Cyflamid 5EW and Domark 40ME that work best to control, prevent and reduce the resistance of the disease, Powdery Mildew for a beautiful rose flower harvest that meets international standards. With roses accounting to 70 percent of Kenya’s flower exports, Amiran clearly understand the need to continuously help rose farmers have an enjoyable farming experience

Powdery mildew is a fungal disease that affects a wide range of plants and is common to many farmers. The disease is caused by Blumeria graminis. It is one of the easier diseases to spot, as its symptoms are quite distinctive. Infected plants display white powdery spots on the leaves and stems. The lower leaves are the most affected, but the mildew can appear on any above-ground part of the plant. As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant.

In light of this, Amiran is this year going a notch higher in the fight against powdery mildew with the introduction of Cyflamid 5EW®, a protectant fungicide with excellent preventive, curative and long residual activity against powdery mildew. With the active ingredient, Cyflufenamid that belongs to the group of benzamidoxime and is the only representative of this group commercialized, its mode of action is unknown. Cyflufenamid is active on all strains of powdery mildew including strains resistant to DMIs, strobilurins, morpholines and benzimidazoles. At rate of 0.5L/Ha, Cyflamid 5EW, offers a new novel way to control powdery mildew, reporting positive results for its;

ü Residual Activity, Vapour Action, Curative Activity & Penetrative Action
ü Both primary & secondary infections control
ü Cyflamid is in the new group U6 for Fungicides Resistance Management
ü Safe for Predatory Mites and Beneficial Organisms (Less Adverse effect on Bees)
ü Excellent Curative and long lasting protectant activity (Active on all strains of Powdery Mildew including strains resistant to DMIs, Strobilurins, Morpholines & Benzimidazoles)
ü Unknown cross resistanceto Cyflufenamid in pathogens that have developed reduced sensitivity to other fungicides.
Domark 40EW, another of Amiran’s field proven solutions to the problematic disease, is a broad spectrum, systemic triazole fungicide with properties for the prevention and cure of powdery mildew at the vegetative stages inside and outside the host plant. Domark 40EW displays a strong residual mode of action by inhibiting the mycelia growth of several phytopathogenic fungi through a specific and selective mechanism. The typical feature of this compound is the presence in its molecule of a tetrafluoroethoxy group. This group causes ideal water solubility and lipophilicity to Tetraconazole, which results in;

ü Fast penetration and translocation within the plant
ü Translaminar movement
ü Systemicity through the upward lymphatic stream
ü Even distribution inside the plant without local accumulation
ü Preventive and curative activity
ü Excellent selectivity due to; No interference with gibberellins biosynthesis (no stunting effects), No inteference with phytosterols biosynthesis (no phytotoxic effects)
In addition to being safe for the operator and the environment, Domark 40EW’s active ingredient, Tetraconazole is characterized by excellent selectivity and for this reason can be applied to any crop, at any stage and can be mixed with different compounds

ü No interference with gibberellins biosynthesis: absence of stunting effects
ü No interference with phytosterols biosynthesis: absence of phytotoxic effects
Amiran experts recommend that application should begin when conditions are favorable for the disease development. At a rate of 0.5-1L/Ha, applications should be repeated every 7 days depending on the level of infection. With Domark 40EW being compatible with commonly used pesticides, Amiran advices farmers to first carry out a compability test prior to full-scale usage.

It is important for farmers to be aware that fungicides are known to cause possible developments of resistance when continually used thus the need for farmers to use fungicides with different modes of actions. Products such as Cyflamid 5EW and Domark 40EW can be used for the rotation spray program.

As new trends emerge, Kenyan flower growers in the future will have to innovate continuously in order to remain competitive, the farmers will need to respond to the permanent pressure on margins, professionalism, increase demand and face growers in abroad countries with excellent farming techniques. Amiran is one input supplier that is increasing partnerships and always carrying out research and investigations on the new, easy and highly effective farming methods that will enable farms to increase their yield while making their farming an enjoyable experience, priding itself in helping Kenyan flower growers remain the leaders in the world flower markets.
