Map Lotus 125WP – Rice Bacterial Blight

1. Symptoms and causes of disease

• Bacterial blight is caused by Xanthomonas Oryzae 
• The disease usually appears first on the leaf edge and then gradually spreads to the leaf blade.
• When newly formed, appears a long pale green streak, then turns greyish-white.
• Lesions have a wavy margin

2. Characteristics and damaging effects

• The disease favors temperatures at 26-30ºC, with relative high humidity 
• The disease enters rice leaves through stomata and mechanical wounds on leaves.
• Xanthomonas Oryzae bacteria can survive on seeds and diseased plant residues.
• Harmful bacteria at the time of flowering will reduce yield.

3. Precautionary measures

• Fertilize balance, do not over-fertilize nitrogen
• When the field shows symptoms of disease, stop using nitrogen fertilizers, foliar fertilizers, growth stimulants.
• Fields with a lot of water need to be drained (should be watered with enough water) and sprayed with pesticides.
• Chemical measures: using Map Lotus 125WP
  • Specifically treats diseases caused by bacteria
  • Wide spectrum of disease, fast effect
  • Dosage: 25g/25liter
  • Should be sprayed early when the disease appears
