Rice Dwarf Disease Spreading Rapidly in Paddy: Experts Advise Farmers to Monitor Fields and Avoid Unnecessary Pesticide Sprays

Key Highlights

• Rice Dwarf Disease is spreading rapidly in paddy fields.

• The disease is caused by a virus spread by the White-backed Plant Hopper.

• Farmers should inspect paddy fields at least once every week.

• Remove infected plants immediately and keep fields weed-free.

• Use insecticides only on the advice of agricultural experts.

Rice farmers are being advised to stay alert as Rice Dwarf Disease is spreading rapidly in paddy fields across several areas. Agricultural experts from Punjab Agricultural University (PAU) and the Ferozepur Krishi Vigyan Kendra (KVK) have warned that the virus-borne disease could lead to major yield losses if it is not identified and managed at an early stage.

Following field surveys in multiple villages, scientists have urged farmers to regularly inspect their crops and avoid spraying pesticides without expert guidance. Timely monitoring and scientific crop management can help reduce the spread of the disease and protect paddy production.

Agricultural Experts Conduct Field Survey

A team from the Ferozepur Krishi Vigyan Kendra, led by Deputy Director Dr. Gurmel Singh Sandhu, recently inspected paddy fields in several villages to assess the disease situation.

During the visits, farmers were informed about:

• How to identify Rice Dwarf Disease

• Ways to detect the insect responsible for spreading it

• Scientific methods to prevent and manage the disease

Experts emphasized that early detection is the most effective way to minimize crop damage.

Farmers Should Inspect Paddy Fields Every Week

Dr. Gurmel Singh Sandhu advised farmers to inspect their paddy fields at least once every week. Any early signs of pests or disease should not be ignored.

He also stressed that farmers should use insecticides or pesticides only after consulting agricultural experts or the Krishi Vigyan Kendra. Unnecessary spraying not only increases production costs but may also fail to control the disease effectively.

According to him, regular monitoring and scientific crop management can significantly reduce disease spread and help farmers avoid financial losses.

What is Rice Dwarf Disease?

According to Dr. Harvinder Singh Buttar, Assistant Professor (Plant Protection), Rice Dwarf Disease is caused by a virus that affects the normal growth and development of paddy plants.

The disease weakens the crop and reduces grain production, leading to lower yields if left unmanaged.

Symptoms of Rice Dwarf Disease in Paddy

Farmers should watch for the following symptoms:

• Paddy plants remain much shorter than normal.

• Leaves become thin and pointed.

• Root growth becomes weak.

• Panicles (ears) do not develop properly.

• Grain formation is poor or absent in severe cases.

• Infected plants may gradually dry up, causing significant yield loss.

White-Backed Plant Hopper Spreads the Virus

Agricultural scientists have identified the White-backed Plant Hopper (WBPH) as the insect responsible for spreading Rice Dwarf Disease.

Since the virus spreads through this insect, controlling its population is essential for preventing further infection.

How to Identify White-Backed Plant Hopper

Experts explained that:

• Nymphs (young insects) are light greyish-white in colour.

• Adult insects have a distinctive white stripe on their back and black spots on the rear wings.

Early identification of the insect can help farmers take timely action before the disease spreads widely.

How Farmers Can Detect the Pest

Scientists recommend a simple field inspection method:

• Gently tilt the paddy plants.

• Shake them two or three times.

• Observe the water surface in the field.

If nymphs or adult White-backed Plant Hoppers float on the water, it indicates the presence of the pest.

However, insecticides should only be sprayed when the insect population reaches the economic threshold level and only according to recommendations from agricultural experts or the university.

Expert Recommendations to Prevent Rice Dwarf Disease

Agricultural scientists have shared several practical measures to reduce the risk of Rice Dwarf Disease:

• Inspect paddy fields regularly, preferably once every week.

• Install light bulbs near fields at night to attract and monitor the insect population.

• Remove infected plants immediately and bury them deeply to stop the virus from spreading.

• Keep field bunds and irrigation channels free from weeds.

• Pay special attention to fields where the disease appeared during the previous season.

• Apply nitrogen fertilizers only in the recommended quantity, as excessive nitrogen encourages higher pest populations.

• Spray insecticides only after expert advice and only when pest levels cross the recommended threshold.

Timely Monitoring is the Best Protection

Agricultural experts believe that regular field inspections, early removal of infected plants, and proper management of the White-backed Plant Hopper are the most effective ways to control Rice Dwarf Disease.

Farmers are encouraged to immediately contact the Krishi Vigyan Kendra (KVK) or the local Agriculture Department if they notice early symptoms in their paddy fields. Following scientific recommendations can help prevent major crop losses and protect overall paddy production.

CMV360 Says

Rice Dwarf Disease can significantly reduce paddy yields if it is not detected and managed at the right time. Regular field inspections, early removal of infected plants, proper weed management, and timely control of the White-backed Plant Hopper are essential to prevent its spread. Farmers should avoid unnecessary pesticide spraying and always seek guidance from agricultural experts or Krishi Vigyan Kendras to protect their crops and reduce production losses.
