Powdery Mildew is one of the most devastating fungal diseases dreaded by rose flower growers due to its ability to destroy huge tracts of the crop within a short time.

And to counter this menace, BASF East Africa Ltd has launched a new product, Vivando, which is described as being in a class of its own due to unique mode of action which works to prevent infections by halting successful powdery mildew penetration.

Registered to control powdery mildew in roses in Kenya, Vivando is best used as a preventative rather than a curative measure. The active ingredient in Vivando, metrafenone, specifically disrupts the proper functioning of the powdery mildew cells.

And although Vivando works best when applied preventatively before powdery mildew infections occur, it also provides targeted protection by interfering with lesion growth and sporulation.

As a preventative, the fungicide should be applied at a rate of 0.7 litre per hectare in a minimum of 1000 litres of water at an interval of 7-10 days depending on the disease pressure.

In case it is applied after a high infestation of the fungi and excessive leaf development, the shorter interval of seven days are advised.

Vivando exhibits a multi-level-activity and effectively protects the plant from powdery mildew attack which gives long durations of control.

“There is none other like Vivando. It on its own class” said BASF Country Manager- Kenya, Crop Protection and Public Health Products, Patrick Ngugi during the launch of the product at a hotel in Naivasha. The launch was attended by over 130 participants from across the flower growing areas in Kenya.

He described Vivando as a creative mode of action with cutting edge technology which is unique by inhibiting the fungus at different stages of growth and infection.

The launch came at a time when more and more farms quest for safer products has intensified as the market residue level measures continue to tighten.

Vivando should be used in a spray program that rotates fungicides with different modes of action such as Meltatox and Collis also products of BASF as it has no resistance with other powdery mildew fungicides.

BASF Managing Director Peter van den Hoek said that as a class IV product Vivando is categorized as a green product by World Health Organisation (WHO) making it safe for the user, predatory mites and other beneficial organisms. It is also Integrated Pest Management (IPM) compatible, meaning it does not affect non-target plants and insects.

He pointed out that the product has been on trials for the last three years and farmers who have used it have expressed satisfaction with the results.

The product is distributed by Elgon Kenya Limited and is available in the agro-chemical stores across the country in quantities of one litre.
