How do you control rice blast disease?

Systemic fungicides like triazoles and strobilurins can be used judiciously for control to control blast. A fungicide application at heading can be effective in controlling the disease.

How do you control neck blast in Paddy?

Systemic fungicides like triazoles and strobilurins can be used judiciously for control to control blast. A fungicide application at heading can be effective in controlling the disease in cases where the risk of yield losses is high.

What are the symptoms of rice blast?

The symptoms of rice blast include lesions that can be found on all parts of the plant, including leaves, leaf collars, necks, panicles, pedicels, and seeds. A recent report shows that even roots can become infected.

What causes decay in rice?

If the node at the base of the panicle is infected, the panicle breaks causing the “rotten neck” condition. In addition, the fungus may also attack the nodes or joints of the stem. When a node is infected, the sheath tissue rots and the part of the stem above the point of infection often is killed.

What are the stages of rice blast?

From the seedling stage through plant maturity, rice blast progresses through several phases starting with leaf blast, followed by collar, panicle and node blast.

What is Khaira disease of rice?

Khaira disease of rice is caused due to deficiency of(1) Boron deficiency(2) Zinc deficiency(3) Magnesium deficiency(4) All of the above. The deficiency of zinc in rice causes khaira disease. They existed as smaller patches in the nursery or might be observed in the main-land of rice. The leaves are discoloured.

What is bacterial blight of rice?

Bacterial blight is caused by Xanthomonas oryzae pv. oryzae. It causes wilting of seedlings and yellowing and drying of leaves.

Which crop is affected by the disease called blast?

Rice is one of the most important crop plants in the world, and the rice blast disease caused by the fungus Magnaporthe grisea is one of the most destructive diseases. The disease is widespread and causes severe losses.

What is sheath blight disease?

Sheath blight is a fungal disease caused by Rhizoctonia solani. Infected leaves senesce or dry out and die more rapidly, young tillers can also be destroyed. As a result, the leaf area of the canopy can significantly be reduced by the disease.

What do you understand by blast of rice?

a disease of rice caused by the fungus Pyricularia oryae, characterized by elliptical leaf spots with reddish-brown margins, brownish lesions and neck rot of the fruiting panicles, and stunting of the plant.

What is the chemical control of potato blight?

The severe late blight can be effectively managed with prophylactic spray of mancozeb at 0.25% followed by cymoxanil+mancozeb or dimethomorph+mancozeb at 0.3% at the onset of disease and one more spray of mancozeb at 0.25% seven days after application of systemic fungicides in West Bengal [50].

What is brown leaf spot disease?

Brown spot is a fungal disease that infects the coleoptile, leaves, leaf sheath, panicle branches, glumes, and spikelets. Its most observable damage is the numerous big spots on the leaves which can kill the whole leaf. When infection occurs in the seed, unfilled grains or spotted or discolored seeds are formed.

How do I know if I have stem rot?

Symptoms of Root and Stem Rot

Check the roots of one of the plants by removing it from the soil and feeling the roots with your hands. If the roots feel mushy and look dark instead of a creamy white or tan, you probably have root rot issues. Sometimes, infected roots will fall off when you touch them.

What is stem rot disease?

Stem rot is a disease caused by a fungus infection in the stem. Fungus that causes stem rot are in the Rhizoctonia, Fusarium or Pythium genera. Stem rot can readily infect crops that are in their vegetative or flowering stages.

How do you prevent stem rot?

Soil-inhabiting fungi like the ones that cause stem rot thrive in moisture. Poorly drained soil, often in combination with warm weather, is an ideal breeding ground. Adding plenty of organic matter improves soil drainage. Another solution for excessively wet soils is to grow your garden vegetables in raised beds.

Which fungicides do we use for seed treatment of blast disease?

Treating rice seeds with pyroquilon and azoxystrobin resulted in the greatest reduction in rice blast disease severity, whereas carboxin + thiram and tricyclazole significantly reduced fungi in seeds¹¹.

Which one of the following is downy mildew fungus?

Cucurbitaceae downy mildew (caused by Pseudoperonospora cubensis) is specific to cucurbits (e.g., cantaloupe (Cucumis melo), cucumber (Cucumis sativus), pumpkin, squash, watermelon (Citrullus lanatus) and other members of the gourd family). The disease is one of the most significant diseases of cucurbits worldwide.
