Key Product Details

What Does Isoprothiolane 40% EC Control?

Isoprothiolane 40% EC controls rice blast, one of the most damaging diseases of paddy. Blast is caused by the fungus Magnaporthe oryzae (also called Pyricularia oryzae).

Isoprothiolane 40% EC Dose per Acre

The recommended dose of Isoprothiolane 40% EC for rice blast is 300 ml per acre (750 ml per hectare), mixed in 200–400 litres of water.

Dose per litre and per pump

The dose per litre depends on how much water you use per acre. Always keep the total at 300 ml per acre.

When and How to Spray

1. First spray: as soon as the first leaf blast spots appear.
2. For neck blast: spray at booting to early panicle emergence stage. Neck blast cannot be cured after the neck has turned black, so spray before it appears.
3. Mixing: add the measured dose to a small amount of water, stir well, then add the remaining water.
4. Coverage: spray evenly so all leaves and the upper stem are covered.
5. Weather: do not spray in strong wind or when rain is expected soon.
6. Harvest: keep a gap of 60 days between the last spray and harvest.

How Isoprothiolane Works

Isoprothiolane is a systemic fungicide from the dithiolane group. It is absorbed through the leaves and roots and moves up and down inside the plant. It stops the blast fungus from entering and spreading in rice tissue. This gives both protective action (before infection) and curative action (early infection).
