When soybean fields start turning yellow, many farmers rush to spray expensive fertilizers or chemicals. But wait! There can be several reasons behind the yellowing of crops.
Let’s look at the 4 main causes of crop yellowing and their exact remedies:
1. Continuous Rainfall and Waterlogging
Due to continuous rains, when water gets logged in the field, the roots cannot breathe (lack of aeration), causing the crop to turn yellow.
- Remedy: First and foremost, drain out the excess water from the field. Spraying should only be done after receiving a clear spell of 2 to 3 days of rain-free weather.
2. Nutrient Deficiency
When the crop does not receive proper nutrition, different symptoms appear on the leaves. For example, in iron deficiency, the leaf veins remain green while the area between them turns yellow. In potassium deficiency, older leaves begin to turn yellow.
- Remedy: When there is sufficient moisture in the soil, apply any one of the following: Zinc Sulphate (5 kg), Ferrous Sulphate (5 kg), or Micro-nutrient Grade-II (5 kg) mixed with 20 kg of NPK 10:26:26 directly into the soil.
3. Yellow Mosaic Virus (Viral Disease)
This is a highly destructive disease transmitted by sap-sucking pests like whiteflies and leafhoppers. If left unmanaged, it can cause up to 90% yield loss.
4. Incorrect Use of Herbicides
Using incorrect doses of herbicides, or mixing herbicides with fertilizers/insecticides, causes leaf scorching and stunts plant growth.
When Traditional Remedies Fail to Revive the Crop…
In such tough situations, to give soybeans a new lease on life and protect them from stress, AMICARB from Amicus stands as a solid shield by your side!
Whether it is harsh sunlight, nutrient deficiency, or yellowing—the special nano-technology in AMICARB quickly pulls the crop out of this crisis.
⚡ Why does AMICARB act as a ‘Life-Saver’ for Soybeans?
- Restores green health to the crop: Rapidly increases chlorophyll content in leaves to resume photosynthesis, keeping the crop fresh even under intense heat.
- Strengthens plant roots deep in the soil, doubling their capacity to absorb nutrients.
- Enhances the crop’s natural immunity against diseases and stress.
💧 Application Method:
- Dosage: 2 grams per liter of water (700 to 800 grams per acre).
- Ideal Time: 30 to 35 days after sowing, or as soon as yellowing is noticed in the field.
☀️ Important Rule During Spraying:
- Change Spray Timing: Always spray in calm weather either in the morning before 9 AM or in the evening after 4 PM.
- Use Clean Water: Always use clean water for spraying and use a good quality spreader/sticker so the liquid adheres well to the leaves.
Conclusion
My fellow farmers, the period between 30 to 35 days forms the foundation of your entire year’s income. Don’t get discouraged or panic and waste money on unnecessary products if your soybean crop turns yellow. First, identify the exact cause, manage field conditions properly, and use Amicus’s AMICARB at the right time to keep your crop green, robust, and healthy!
