Major disease of rice
1. brown spot disease
The disease is spread in almost all parts of the country , especially in West Bengal , Orissa , Andhra Pradesh , Tamil Nadu and more. It is a major disease in North Bihar . It is a Bijjnit disease .
In this disease, paddy grain from the root up to the harm. The disease causes the leaves to become spherical brown Dbben. This disease is generated Ffaund. Plant growth is lower, the seeds are affected, which also have an impact on their viability. Sesamoid on the leaves become brown to black Dbben. These Dbben in shape and size from very small dot size is rounded. Light yellow aura is formed around the spots. They are scattered on the leaves completely. Part of the spots are white or purple. There is a large dark brown spots alongPart of the cream, marigold, white or gray color becomes. Ugravstha plants in most of the leaves from the bottom up are filled with spots. They have to grow together in mutual Dbben, and the leaves have dried up. The black spots are formed on the cover. The outbreak of the disease in areas with lower fertility in paddy Uprau months between May to September is more visible. This disease is mostly seen in those areas where farms Farmers are not arranged in the proper management, find. In addition to the plant's root It can all be patient. In this disease grain brown to black on the Chilko Dbben is formed, becomes discolored rice
1. seeds Thyrm and Carbendazim (2: 1) and treated at the rate of seed per kilogram of drug Ugram must sow.
Varieties such as disease Shnshi Bala Krishna, Kusuma, Kaveri, Rasi, Jagannath and IR 36, 42, etc. to practice.

2. breath (blast) disease / Prdhvans (Blast)
The disease is transmitted by the fungus called Pirikuleria Oraiji. Rice blast disease, it is extremely destructive. The leaves and small on their lower parts and blue Dbben is formed, and later grew in size, they become like Dbben boat. Bihar mainly outbreak of the disease is found in aromatic rice. The symptoms first appear on the leaves, but the invasion sheath, Pshpakram, Ganto and grains is also on Chilko. Mainly leaf blast, blast and neck blast Prwsandhi as there is in this disease. It is Ffuँdjnit. Fungal plant leaves, Ganto and affects the base of earrings. Part of the ash-colored spots and edges are brown like the circle, which is up several centimeters big. When the disease is raging, based on the Bali also become diseased, and Bali is weak and crumbling of the same. Brown spots in the central part is white. In this stage, there is more damage. Brown lump-darkening and decomposition in the event of breakage, be Kkdi of seeds and fungi on Bali's white mesh to be 'good rat is called. Sore point between the gray color is part of. Many Kshtsthl get up in each other in a friendly atmosphere, the resulting dried leaves are Julskr. Dbben is becoming too brown on Gato, which does harm to the proper plant. Tno whole or part of the tumor turns black, Kallon Ganto of fungus attack is made with the brown Dbben, which is covered with lumps around the plant breaks. Earrings gray-brown color on the lower stalk Kshtsthl is formed, the "neck rot" is called. The rash is not formed in the patient earrings, and earrings are crumbling rotten part. Leaf blast of ash on the leaves in the central part of the same gray and brown edges or large conical shaped eyes is Bnten Dbben.
Flowering time Prwsandhi Blast Prwsandhi part becomes black, and the plant breaks the space. The breakdown takes the burden of disease due Dndl earrings, because the lower part of the cervical infection is weakened. Get great impact on the yield of paddy. Neck blast, panicle, ranging from brown to black on the base portion has become Dbben, which is surrounded from all sides Milkar, and often falls down, there is panicle. Serious outbreak of the disease's secondary Takili and rash have also become infected. Resulting in the loss of the component crops.
Kaptan seed before planting Bevistin 2 grams or 2.5 grams per kilogram of seed rate of drug treated it.
Netrajn proper amount of fertilizer should give a little bit on the times.
Standing crop in 250 g Bevistin Kilagram Indofil +1.25 M-45 dissolved in 1000 liters of water per ha should be sprayed.
Hinosan also can be sprayed. Given the disease in a spraying nursery, and two or three spraying interval of 10-15 days to get the earrings should be.
Beam 300 mg doses of the drug dissolved in 1000 liters of water can be sprayed.
Disease resistant varieties such as IR 36, IR 64, Pankaj, Jamuna, Srju 52, pneumatic and rice pant should grow 10 etc.
3. Parnchcnd blight / Sith / Banded blast disease / Achcnd scorching / leaf blight / sheath blight / cover blight disease (Sheath Blight)
Rice sheath blight, a disease which still generally considered a major disease in India as it unfolded in paddy fields is developed. The disease, called factor Raijoktonia Solenai mildew, which we know by the name of Thenetifors Kukumeris. Cover the mold on plants above the water surface as elliptical greenish slate / white blur dictates. Based on leaves and leaves striped green-brown or straw-colored large patient base is formed. It is surrounded on all sides to Tno later, Kshton Sletipan the central part is the white, red and brown on the edges and the wound and flowering stage in rice plants at the time of Dujiya is formed. The symptoms of this disease mainly appear on the leaves and sheath. In favorable conditions, mold small black grains of brown leaves on the surface of the produce, who says Skleropiam. These Skleropia lighter falls down to shock. Ugravstha of disease in the cover up symptoms on the leaves produces. All leaves are beset. The plant appears to be charred, and earrings out of the casing does not come. Earrings corn become discolored. While proper temperature and humidity in the atmosphere, and the mycelium is visible Skleroshiam kind of lentil seeds. Symptoms of the disease appear in the final stages of becoming Kallen. Leaf sheaths above the surface of the water has started to have spots. In plants in yield due to this disease can cause loss of up to 50%.
disease Control :-
Jekestin or Indofil Bevistin 2 kg or 2.5 kg quantity of M-45 dissolved in 1000 liters of water per ha spray.

4. bacterial leaf blight disease / bacterial leaf blight disease (Bacterial Leaf Blight)
Bacterial leaf blight disease is almost an embarrassment to the whole world. In India, mainly developing the disease Pradeshaen such as paddy in Punjab, Himachal Pradesh, Uttaranchal, Uttar Pradesh, Cttishgdh, West Bengal, Maharashtra, Karnataka, Tamil Nadu and extends out. In addition, many other states have also seen this disease. In India, the disease has become the most serious problem. The disease is spreading fast also in Bihar. The disease Janthomonas Oraiji PV Oraiji is caused by bacteria called.
It is primarily a disease of the leaves. The disease occurs in the two states, leaf blight phase and phase Kresek. Jldharit green-yellow spots on the upper side of the leaves first as a disease emerges. Grows on the leaves yellow or straw colored wavy streaks starting from the end of one or both sides is growing downwards and leaves dry up. Dbben stripe parallel to the edge of the leaves as they grow in. Gradually the whole leaf color changes in wood. These stripes are Diri veins, and yellow or orange color is brown. Khruwa color of pearl-like small yellow stripes on the substance of the bacteria is found, the leaves are dried up prematurely. The damaging stage of disease or Kresk Mlani, making the whole plant dries. The patient lay on the glass of water on the leaves and chop the glass becomes milky color. Symptoms of bacterial blight in rice plants is visible in two stages. Mlani stage (Kresek) and leaf blight (leaf blast) leaf blight, which is more comprehensive. Scorching stage: on the leaf surface has become worn irrigable, and the upper ends of the leaves is their introduction. Later, pale yellow or straw color of the wound become and their spread is down with wavy edges. These injuries were Uttikshyi later wither fast. Mlani or Kresek stage: This stage of the disease in the nursery during the start Dujiya become visible. Pitima and suddenly Mlani its general characteristics. Mlani fact is characteristic of the second stage. These symptoms appear within 3-4 weeks after transplanting to begin. In this stage, the leaves of infected plants in length shrinks turns inward. The resulting whole leaf wilts, who later dies dried. Sometimes Kshtsthl between leaves or along the mid-rib is found. Srav droplets containing the bacteria in the infected part implies. It dries to form Srav become rigid. Knikaaॅ orange and pale yellow. Or as a scab appears. The bacterium is part beset leaks. In the field will be deposits of water from the paddy stink. Sheath is infected, the symptoms are similar to the leaves. The fiery stage disease in the affected plants completely die.
