Control of fungal and bacterial diseases affecting rice, vegetables and fruit. On rice, it controls diseases caused by Pyricularia oryzae and Burkholderia glumae (bacterial grain rot), with ground and aerial applications, at 20-30 g/ha, and seedling diseases caused by various bacterial pathogens, at 0.3-0.6 g/box. In sugar beet, it controls Cercospora beticola, at 80-100 g/ha. Also used to control plant diseases in various crops: Pseudomonas syringae pv. lachrymans in cucumbers, at 30-60 g/ha; Colletotrichum lagenarium in melons and water melons; Cladosporium fulvum and Corynebacterium michiganense in tomatoes, at 20-40 g/ha; Mycovellosiella nattrassii in aubergines; Cercospora apii in celery; Erwinia carotovora subsp. carotovora in potatoes, carrots and onions; Pseudomonas syringae pv. coronafaciens (halo blight) in kidney beans, at 40-60 g/ha; Xanthomonas campestris pv. vesicatoria in paprika; Venturia inaequalis in apples; Pseudomonas marginalis pv. marginalis in kiwifruit; etc. 【Physio-chemical Properties】: Form Colourless needle crystals.
