As one of the world’s most important agricultural commodities, rice is grown on the majority of tropical and sub-tropical land. Despite tremendous research and development efforts, diseases and pests remain formidable constraints to rice production. One of the most severe diseases of rice is sheath blight caused by the fungal pathogen Pyricularia oryzae (Mart.) Desm. What is a fungicide? You might think that it’s a type of spray that kills fungi. Well, you’re partly correct — but there’s a lot more to it than that.

Best Fungicide For Rice Sheath Blight

Introduction

Rice Sheath Blight is the common name for a fungal disease caused by Rhizoctonia solani or Thanatephorus cucumeris. This disease can cause significant damage to rice crops in affected areas. Throughout this article, we cover everything you need to know about Rice Sheath Blight including identification, treatment options, and prevention methods.

What is Rice Sheath Blight?

Rice Sheath Blight is a fungal disease that is caused by the fungus, Magnaporthe oryzae. This pathogen can infect both transplanted and paddy-grown rice plants and causes significant damage to crops. Rice Sheath Blight can result in yield losses of up to 70% if left untreated. The disease spreads quickly, so early detection is crucial for successful management of this infection.

It is important to remember that not all browning on rice leaves are due to Rice Sheath Blight; other diseases such as bacterial leaf blight, black point disease and blast may cause similar symptoms as well.

What Causes Rice Sheath Blight?

Rice sheath blight is caused by a fungus that attacks the rice plant and can be spread by wind, water, insects and equipment. It’s generally a problem in both wet and dry seasons.

How To Identify Rice Sheath Blight

Rice sheath blight is a fungal disease that attacks rice plants. It typically occurs during the growing season, which is usually spring and summer. It’s important to identify this disease so you can take steps to prevent it from becoming a widespread problem. Here are some signs you should look for if your plants are showing signs of rice sheath blight:

• Brown streaks on leaves, stems and sheaths (the leaf stems attaching the plant to its stalk)
• Brown streaks on leaves, stems and sheaths as well as panicles (the part where grain develops)

How to Treat Rice Sheath Blight

• Remove infected leaves. This is the most important step to controlling this disease. If you do nothing else, take off any diseased leaf tissue and dispose of it in a trash bag that is not touching other plants or soil.
• Spray fungicide. If you find signs of sheath blight on your rice crop, spray with a fungicide immediately! It’s best to use a seed treatment with an active ingredient like mancozeb or thiram as soon as possible after planting (but before germination).

Rice Sheath Blight is a common, fungal disease that causes significant damage in rice growing areas.

Rice sheath blight is a common, fungal disease that causes significant damage in rice growing areas. It is caused by a fungus called Fusarium.

Rice sheath blight disease was first reported in the United States in 1953 from Louisiana and Mississippi. The Asian strains of the disease have been recorded since 1916 and have spread to many states including Alabama, Arizona, California and Texas. As an invasive species rice sheath blight has caused considerable damage to U.S.-grown rice crops since its introduction into this country more than half a century ago.

The pathogen produces two distinct types of spores: conidia (symbiotic spores) and chlamydospores (sporangia). Both are produced on dead tissues during infection periods; however, they may also be produced on living tissues where they germinate within hours after production at temperatures below 25°C or above 30°C respectively. Sporulation occurs during periods of high humidity or rain when temperatures are between 15°C – 25°C with optimum development occurring at 24 – 26°C but can occur as low as 10°C for certain strains under optimal conditions for growth

(Wilmot et al., 1982).

Conclusion

Rice Sheath Blight can be treated with fungicide in order to prevent further damage. In areas where the disease is known to occur, it is important for farmers and gardeners alike to monitor their plants regularly so that they can get rid of any signs of infection as soon as possible.
