Straighthead disease in rice is an physiological disorder linked to arsenic toxicity or induced stress in older paddy soils. II. Arsenic-methylating bacteria convert inorganic arsenic into organic forms like DMA and MMA. III. A higher ratio of methylating to demethylating microbes increases the risk of arsenic accumulation in rice grains. IV. Draining rice fields midseason (intermittent flooding) and silicon fertilisation can help reduce arsenic uptake by rice plants. How many of the above statements are correct?
