Kenya is among the world’s biggest exporters of cut flowers, particularly roses and carnations. This would not be possible without chemical crop protection, because a variety of pests can spoil the appearance - and thus considerably reduce the marketability - of ornamental plants: here, fungal plant pathogens are a particular problem.
Strengthening the fungicidal armory
Since 2002, Kenyan cut flower producers have been able to rely on Flint® 50 WG (trifloxystrobin). This strobilurin fungicide, which has already proven its worth in a variety of crops in a number of countries, is perfectly suited for protective treatments against powdery mildew and rust on roses, and against rust, leaf spot and ring spot on carnations.
Mesostemic properties
Trifloxystrobin undergoes mesostemic redistribution: in other words, as soon as it has been applied, the active substance forms a stable depot on the plant surface, from which it gradually enters the plant’s tissues. Thus, Flint possesses the ideal combination of excellent weather-resistance and a long duration of action.
Protective treatment is necessary
In practice, Flint is applied preventatively (up to four times a season) at 7 – 10-day intervals, in alternation with sprays of products with different modes-of-action. In treatment programs against powdery mildew in roses, successive sprays with trifloxystrobin must be separated by two treatments with a non-strobilurin fungicide. This precaution is necessary in order to prevent the pathogen from developing resistance to strobilurins.
A key product
Bayer CropScience’s fungicide has already established itself as a key product for controling rose mildew and carnation rust in Kenyan cut-flower cultivation. It also fully meets the requirements of the Kenya Flower Council, whose effective auditing systems ensure strict observation of high standards of environmental protection and safety for the user.
