What to Do About Herbicide Damage in Soybeans? A Detailed Guide to Remedies

In the growth process of soybeans, pesticides and fertilizers are unavoidably needed, but when experience is lacking, herbicide damage is easily caused, so what should be done about herbicide damage in soybeans?

1. Growth Habits of Soybeans

Soybean is a crop of the Fabaceae family and the genus Glycine, also called shu, yellow bean, etc. It is mainly distributed in countries such as China, the United States and Brazil, and its planting area in our country is also relatively large, making it a relatively important crop.

Soybean is a crop that likes a warm growing environment. The seeds begin to germinate at 10-12°C, and grow best at 15-20°C. During the flowering and pod-setting stage, the temperature is best kept at 20-28°C, because at low temperatures soybean pod-setting will be delayed, so the temperature should preferably not be too low, and below 14°C soybeans cannot flower.

But if the temperature is too high, the plants end their growth early, so it is best to control the temperature for soybean growth. Seed germination requires more water, and during the flowering stage the soil moisture content is required to be 70%-80%, otherwise the rate of flower bud shedding increases. Before flowering, soybeans absorb less than 15% of the total nutrient uptake, while the flowering and pod-setting stage accounts for more than 80% of the total nutrient uptake.

2. What to Do About Herbicide Damage in Soybeans?

1. You can spray some plant growth regulators, which have a certain alleviating effect on mild herbicide damage;

2. When soybeans show herbicide damage symptoms such as yellowing, you can also increase fertilizer application to alleviate the damage;

3. If it is herbicide damage from soil-applied chemicals, it can be handled by methods such as plowing to reduce residues.

3. How to Store Soybeans

Because soybean is a crop with strong moisture absorption and is prone to mold, it must always be stored in a cool, dry place, preferably sealed, to prevent soybeans from becoming moldy. The signs of soybean deterioration are: the bean grains become soft, the seed coat is dull and whitish, a slight off-odor appears, followed by the bean grains swelling, deforming, the hilum turning red, and colonies appearing on broken grains, with quality deteriorating sharply.

If soybeans show the above conditions, in mild cases you can put the soybeans in the sun to dry them thoroughly and then continue to use them; if the situation is relatively serious, it is best not to use them again.
