sarocladium oryzae (Sawada) is a plant pathogen that causes sheath rot disease of rice and bamboo blight of Bambu soideae spp in asia.
How to care of sheath rot disease Rice sheath rot is a complex disease caused by various fungal and bacterial pathogens.
The main pathogens associated with the sheath rot of rice are fungi such as Sarocladium oryzae and Fusarium sp.
The Fusarium fujikuroi complex and the bacterial pathogen Pseudomonas fuscovaginae belong to the family.
Rice generally plays an important role in the food security of developing countries, rice cultivation is usually subjected to multiple environmental pressures,
lack of nutrients and the prevalence of various diseases. How to care of sheath rot disease The yield loss due to
the infection of various types of pathogens is more than 40 percent. it’s seed borne.
position disease animals and substitutes. the prevalence of this disease is lugh in trees affected by maggots and the tungro disease.
How to care of sheath rot disease the disease increases in hot and humid weather. Sheath rot disease spreads during rain showers. kholpacha disease is seen in all seasons.
generally, the disease is favorable for this disease when the tree is in cold in industry and for animals feed.
in the asia the contained accounting for 90 % of the world production. due to this production is restricted and the attack of various pets is increased.
How to care of sheath rot disease, in this disease, the sheath basically rots and degenerates, leading to blockage and sterility.
Sheath rot disease was geographically limited to a small Extend but recently its prevalence has increased Considerably in the1960s,
the green revolution in Asia brought about major changes in rice cultivation including lugh yielding varieties
increased use of manure, advanced system of sowing and seeding, etc. How to care of sheath rot disease crop Intensification
practices such as increased plant density, a high complex is one of them. it is assumed that the new susceptible cultivars have lost
the ability to avoid flowering in high the humid and high in temperature conditions, which are conducive to effective disease attack.
sheath rot disease can be caused by various fungal and belongs to the bacterial pathogens, Fusarium funjikuroi complex and belongs
the bacterial pathogen Pseudomonas fuscovaginae. various other pathogens have been associated with sheath rot of rice.
Symptoms of Disease
How to care of sheath rot disease has been Leaves are never diseased. Leaf blight can occur on any pod, but Damage occurs only when leaf pods are infected.
Attack of this disease Seen when rice is infected. The first is round or irregularly long Stains on end leaf sheath. The center of
the spot is gray and the edges Brown or grayish brown. The spots may grow together and spread completely Open pod
faces or pods rot and powdery mildew is abundant. sheath rot disease If the attack of the disease is more,
sometimes the rash is partial or not able When it comes out, the rice turns black and shriveled.
This disease is usually found in rice plants injured by spider mites or other diseases.
hot temparecher is also associated with virus-infected plants for diseases in hot and humid weather.
sheath rot disease Early symptoms are numerous irregular oblong spots with gray centers and brown margins.
Spots or rots appear on the leaf sheaths that surround the young roots, discoloration is seen between the spots.
In severe infections, not all parts of young roots emerge. And exposed roots within the sheaths will rot quickly, and powdery mildew will grow inside the leaf sheaths.
Infection occurs on the upper part of the leaf at all stages. But it is more harmful at the boot stage.
How to Care of Sheath Rot Disease Management
sheath rot disease are Researchers have recommended removal of infected straw and weeds from the field,
with recommendations for planting at 25-25 cm density. They recommend applications of other fertilizers including potassium,
calcium sulfate and zinc sulfate to strengthen stem and leaf tissue. How to care of sheath rot disease is the best way Blight researchers and
development departments of various countries, advised to use disease-free seed plants. Seed treatment with fungicides such as
mancozeb and benomyl effectively removes seed-borne inoculum, and increases crop yield and quality and reduces
the risk of comparative losses, benefiting farmers. During the booting stage, foliar sprays with carbendazim, adifenfos or mancozeb reduce sheath rot.
Spray carbendazim 250 gm or chlorothalonil 1 kg or adifenfos 1 l/ha. Monocropping with any breed requires regular monitoring of era and field.
Cure disease Use healthy seeds. Treat with Carbendazim (outstein) or Carboxin +Thiram (Provex 200 w p) at the rate of 2.5 g per kg of seed.
How to care of sheath rot disease Area around land should be kept clean. Balanced fertilizers should be used and less urea
should be given Applied potash fertilizer should be applied. If the bark rots, water it Irrigation water should be
given again after a few days after drying the land. Propiconazole (Tilt 250 E C) should be mixed at the rate of 1 ml in 1 liter of water.
And spray 2-3 times after 10 days. Treatment: To cure sheath blight disease, application of a combination fungicide is necessary,
such as mancozeb 75% w p, captan 70%, Hexaconazole 5%, @ 750 g/ liter should be given.
Mainly sheath blight disease has been controlled by using foliar fungicide, Carbon dajim should be mixed with 1gram/liter of water and applied.
Conclusion
How to care of sheath rot disease. The disease in some country all the world Found more frequently over time,
It has become an important disease of rice and is widely observed in other countries of the world. Farmers’ awareness must be greatly increased for prevention.
Basic awareness and proper treatment can prevent this roger epidemic.
