What to Do If Soybeans Suffer Herbicide Damage from Corn? Detailed Remedial Measures
Soybeans are an important food crop in our country, widely planted in the south with a large planting area, but during the growing period they can suffer herbicide damage from corn, so what should be done if soybeans suffer herbicide damage from corn?
1. What to do if soybeans suffer herbicide damage from corn?
If the herbicide damage to soybeans is mild, generally no treatment is needed, and they can fully recover within two weeks. If the damage is severe, spray with brassin, gibberellic acid or foliar fertilizer, or apply an appropriate amount of urea.
2. When should soybeans be sprayed with chlormequat?
1. Whether to spray chlormequat on soybeans depends on the weather and the growth of the soybeans; it is not always necessary. It is generally used because the planting is too dense or there are too many rainy days, causing the stems and branches at the seedling stage to become thin and elongated. Chlormequat is generally sprayed more than ten days before the flowering stage.
2. Chlormequat can be used on soybeans. It can make soybeans shorter and sturdier, with well-developed roots, thicker leaves, deeper leaf color, and enhanced photosynthesis, thereby promoting reproductive growth, increasing pod-setting rate, improving quality, and increasing yield and the ability to resist drought, cold and salinity.
3. Generally, when soybeans have 4 compound leaves, spray each mu with a 0.1% chlormequat solution, then spray once more with a 0.5% chlormequat solution at the early flowering stage, spraying 50 kg of solution per mu each time.
4. After soybeans have flowered, chlormequat can also be applied. This is because the role of chlormequat is to control the plant's vegetative growth and promote its reproductive growth. So applying chlormequat during the flowering period has certain benefits for its flowering and fruiting. However, the flowering period is not the best time to apply chlormequat. If conditions permit, it is best to spray it more than 10 days before flowering. This is more beneficial for its flowering and fruiting.
