Maize bacterial wilt, also known as base rot or stem rot, is a worldwide disease. Maize bacterial wilt generally starts from corn filling stage, and the peak is from milk ripening stage to wax ripening stage. After maize was infected with bacterial wilt, the stem base became soft and brown. White mycelia or red mildew will be found when the 1-3 nodes of the stem base turn brown. Stem rot can be caused by a variety of pathogens, of which the main pathogens are putrescent fungi and fusarium. According to the researchers, the main pathogens can change depending on the region.
Prevention and control technology and measures
Reduce the bacteria source、The seed processing、Enhanced water management、In suitable late time、Fertilization should be adapted to local conditions, as far as possible to measure soil with fertilizer fertilization, in order to increase the growth of corn required nutrients, improve disease resistance and so on.
