What is the purpose of corn seed dressing? Detailed explanation of precautions

After entering spring, it is also the sowing time for spring corn, and I believe everyone is familiar with corn seed dressing. Corn seeds after dressing are bright red, and the seedlings grown from them have slightly better growth and yield than ordinary seeds. So what is the purpose of corn seed dressing? What should be noted? Let's take a look together.

I. Functions of corn seed dressing

1. Preventing seed rot

Although spring temperatures are rising, the temperature is still unstable and the ground temperature is relatively low, which is extremely unfavorable for corn germination. When many farmers plant spring corn, they often see missing seedlings and rotten seeds after sowing, which is caused by the ground temperature. After corn seed dressing, a protective film forms around the seeds, preserving temperature and resisting the attack of low ground temperatures, ensuring normal corn germination.

2. Preventing diseases

Generally, seed dressing agents contain fungicides that can prevent some diseases during the corn growing period. Diseases in the corn planting process are irreversible, so prevention must be done in advance during production, because once disease occurs later, it will more or less cause some impact on corn yield, and seed dressing can provide excellent disease prevention.

3. Preventing pests

In addition to fungicides, seed dressing agents also contain insecticides, which can excellently prevent underground pests and some above-ground pests during the growing period, such as wireworms, white grubs, aphids, etc. After corn is sown, it will suffer from gnawing by underground pests, causing failure to emerge or weak seedlings. After seed dressing, underground pests will not gnaw on the seeds, and during the growing period it can also excellently prevent aphid damage.

4. Preventing lodging

When corn seeds after dressing are sown, their root systems penetrate downward better and are more developed, which also improves the later lodging resistance of corn. In addition, because their growth capacity is relatively lighter, yield will also increase somewhat.

II. Precautions for seed dressing

1. Do not soak seeds to promote germination, because after the seed dressing agent dissolves in water, it will not only make the seed dressing agent ineffective, but after dissolving in water it will also inhibit seed germination.

2. Poisonous items such as medicine bottles, seed dressing tools and residual seeds should be kept away from libraries to prevent poisoning of people and livestock.

3. The pesticides used during seed dressing should be operated according to correct operating procedures, and the dosage of the agent must not be increased at will.

4. After seed dressing, seeds should not be planted in saline-alkali land or low-lying waterlogged land. Both of these terrain types will cause the seed dressing agent to lose its original effect and will also cause the seeds to rot.
