UK study sees climate change affecting disease
Climate change will modify the spectrum of diseases that damage crops, says a BASF-commissioned study by the UK agricultural consultancy, ADAS. In a majority of cases, the severity of disease outbreaks will increase. It bases it findings on the predicted temperature increase of some 2°C by 2050 and more variable rainfall, with wetter winters and drier summers, and more heavy rainfall events and thunderstorms. It says that brassica diseases such as dark leaf spot ( Alternaria brassicicola), white blister ( Albugo candida) and black rot ( Xanthomonas campestris pv campestris) are likely to be exacerbated by high temperatures, while powdery mildew could increase in warmer, drier summers. The study talks about similar variability in diseases on other vegetables.
