The low temperatures and continuous rains this season in the Ancash region (Peru) provoke the appearance of fungi that seriously affect avocado and mango plantations.
The unfavorable climate has caused the appearance of Cladosporium spp., also known as 'The flower fungus', which today particularly damages the plantations in the Moro district and in the Nepeña valley, whose production is destined for international markets.
The aforementioned pathogen can harm up to 90% of the avocado and mango crop.
Cladosporium appears in the flowering phase of the crop and when the humidity level exceeds 90%. The fungus is considered complicated because it causes the fall of the petals of the flowers and prevents the fruit from setting.
Last week, the weather station installed at the Center for Agricultural Research and Entrepreneurship (CIEA) in the Moro district recorded temperatures between 12 and 14 degrees, while the relative humidity exceeded 90%, precisely favorable conditions for the appearance of fungi such as Cladosporium spp.
Active ingredients like Azoxystrobin, Prochloraz, Pyrimethanil, Difenoconazole, Mancozeb or Propineb can control this fungus. The flowering phase lasts up to 60 days and in that term it is necessary to make 4 applications to disinfect the plants.
