Onions are one of the most important vegetable crops in New Zealand with significant volumes exported. Disease and pests can significantly reduce yields and can negatively impact bulb quality which can reduce storage life. Bayer Crop Science has an innovative product range for the most important pests and diseases in onions. This includes the insecticides Confidor and Proteus for thrips control and the white rot fungicides, Luna Devotion and Cereous and Reason, a highly effective option for controlling downy mildew.
