Yellow Mosaic Virus in Soybean – Symptoms and Solutions

Farmers, at many times, face an issue of Yellow Mosaic Virus in soybeans. It is one of the most damaging enemies of the crop and highly impacts the yield and health of the plant. This Yellow Mosaic Virus in soybean not just affects the leaves of the plants but instead targets the entire plant, which leads to a reduction of flowers and a drastic cut down in the yield. And if the infection is not taken care of at the right time, it is going to wipe out the whole field in no time. 

In this blog, we will take a look at Yellow mosaic symptoms in crops and how to prevent yellow mosaic virus. If this is something you want to know about, continue reading. 

What is Yellow Mosaic Virus?

Yellow Mosaic virus is a disease that is usually transmitted by the whitefly (Bemisia tabaci). Yellow mosaic symptoms in crops during the early to mid-vegetative stages of growth. It usually spreads during the warm, humid weather. The infected crops show stunted growth, which, as a result, reduces the yield, causing the loss of around 30% to 100%. But it usually depends on the severity and timing of the infection.

Solutions: Managing Yellow Mosaic Virus in Soybean

1. Use Resistant Varieties

The most effective long-term solution is to grow YMV-resistant or tolerant soybean varieties that include JS 335, JS 9560, or NRC 86. These are resistant, and they can withstand the attack and will show minimal symptoms under high disease pressure.  

2. Seed Treatment

Soybean virus disease control is necessary, and seed treatment helps with it. Imidacloprid 70% WG @ 5 g/kg seed before sowing is a perfect option to use. The treatment helps in protecting the emerging plant from early-stage whitefly attacks.

3. Monitor and Control Whiteflies

It is important to have timely monitoring of crops to ensure soybean virus disease control. Make sure that you are scouting for whiteflies as early as 10–12 days after you sow the seeds. Farmers can also make use of yellow sticky traps, which help in reducing the adult whitefly population. You can use Imidacloprid spray to get rid of any type of Whiteflies, and repeat that after 10–12 days if whitefly infestation persists.

4. Timely Weed Management

On-time management of whiteflies is important as it can also lead to weeds such as Parthenium and Croton growth in the crop. They usually act as the host for both whiteflies and the virus. Timely viral disease treatment in soybeans can keep the field safe and weed-free during the growth stage. 

5. Avoid Early or Late Sowing

Sowing is important for the soybean crop, but it’s important to be mindful about the recommended time of sowing to avoid peak whitefly population periods. If you don’t sow crops at the right time, they become more susceptible to whitefly attacks and other virus infections. 

Cultural Practices That Help

Here are some of the cultural practices that you can in keep the crop safe from virus infections and whiteflies. 

• Opt for the inter-crop method, plant maize or sorghum to reduce the spread of whiteflies.
• Make sure to keep adequate space between the plants for better air circulation. 
• If you are growing in the canopy, it’s important to reduce the humidity.
• Make use of fertilizers to increase the resistance towards these infections.
  
  

Final Words

Yellow Mosaic Virus is one of the most difficult to deal with in terms of the soybean crop, and it can cause serious damage. But with timely monitoring, it is easy to detect the virus or other issues that crops might be facing and can be controlled before it gets too late. Seed treatment, pesticides, virus resistant seeds and using some cultural practices together can help in protecting the crop for secure and higher yield.
