Bulb cultivation

During cultivation season or storage season, various diseases may be transferred by flying aphid. Virus-spreading by this louse proceeds before, during, or up until several weeks after flowering. The Fusarium and Botrytis moulds as well as various types of mosaic viruses can be true tormentors.  Once a bulb is infected with a virus, it transfers to all offspring. The grower of course wants to prevent this and thus the protection of the crop requires his continuous attention.

When spraying against flying aphids it’s very important that the product penetrates deep into the crops. The Wingssprayer spraying technique offers the solution. By positioning the wings immediately above the crops, spraying might even be performed even without touching the crops. Due to the small mutual nozzle distance of 25 cm, and a complete protection against the wind, the wing is capable of spraying deep inside the crops.
In the UK, various flies lay their eggs at the base of the plant between mid-May and the end of June and form a problem in cultivation. The larvae penetrate into the bulb. When the larvae are full-grown (during spring), they leave the bulb. Thereby, the inside of the bulb has become strongly corked and has a hole in its edge.

The bulbs often grow less fast and have one or more deep holes inside of them, whereby there point of growth is lost. Because the fly lays its eggs at the base of the plant, this is the place where spraying is most needed. The Wingssprayer simply opens up the crop, whereby the fine spraying mist penetrates deep into the crop and kills all flies, larvae and eggs.
