Nut trees

Humid summers and mild winters facilitate the spread of a range of diseases in nut trees. Marssonina juglandis and the bacterial walnut blight (Xanthomonas juglandis) can lead to crop failure on a massive scale and reduced growth in walnut trees. Pests such as walnut fruit flies and nut weevils can also heavily afflict walnut trees. Effective crop protection is a key cornerstone of ensuring a good yield at harvest and growing healthy nuts. In order for the trees to be able to withstand high levels of infection, the pesticide needs to thoroughly penetrate the foliage so that all the leaves are fully and evenly coated. VICAR radial blowers are equal to this task thanks to the high air speed that they achieve with a lower volume of air compared to other types of blowers. The air, which serves to transport the pesticide, can thus be better directed and positioned to achieve an efficient, sparing application with minimum drift. Thanks to their powerful and adjustable airflow, the radial blowers allow you to penetrate the entire foliage of both seedlings and fully established trees up to 20 metres in height. The high power turbines are easy to operate right from the tractor via hydraulic vertical adjustment. The result is a highly flexible spraying system that can be tailored to the specific needs of the crop.

Great flexibility thanks to the various air outlets

The variety of settings for the air outlets on the turbines from the 450 and 540 series, and the different types of outlets for the turbines from the 430 series from VICAR, are a great advantage for businesses growing a range of crops and trees: they only need one device for their entire crop protection.
