AGGRAVATED by climate change, fungal disease infection resulted in yield losses in the onion supply in Badoc town in Ilocos Norte. An assessment by the municipal agriculture office revealed that the areas planted to the red onion variety have decreased by almost 50 percent because of the sudden occurrence of the plant’s disease during this year’s planting season. Cornelio Dinong, Badoc municipal agricultural technologist, said the dominant fungal diseases that hit the growing onions are the “anthracnose” and the purple blotch, which usually develop during drizzles and the rainy season, and are further aggravated by climate change. To eliminate the fungal disease causing microorganisms, intensified information campaign was staged urging local farmers to practice soil sterilization and crop rotation at the onset of planting season. Farmers, meanwhile, have chosen to grow hybrid corn, mungbean and high value vegetables in their field in lieu of onion.
