When do peanuts spray paclobutrazol on their leaves?

Peanuts should be sprayed with various chemical fertilizers and pesticides during their growth, so when do peanuts spray paclobutrazol on their leaves? Let's have a look!

What is paclobutrazol?

Paclobutrazol is actually a kind of plant growth regulator, which is suitable for many plants, such as rice, fruit trees, tobacco, rape, soybean, flowers, lawn and so on. Its main function is to delay plant growth and inhibit stem elongation. Shorten internodes, promote plant tillering, increase plant resistance, increase yield and so on.

However, the medicine should be used in strict accordance with the instructions to avoid drug damage. if the dosage is too much and the crop growth is excessively inhibited, it can be rescued by adding nitrogen fertilizer or spraying gibberellin.

When do peanuts spray paclobutrazol on their leaves?

Generally speaking, peanut leaves are sprayed with paclobutrazol when the needle falls to the soil, which can not only supplement nutrition to the plant, but also prevent the plant from growing, and also has a certain control effect on some diseases. When spraying, choose the top growing point of spraying seedlings after 4: 00 p. M. on a sunny day to avoid high temperature spraying, re-spraying, leaking spraying and rain after spraying.

Third, why spray paclobutrazol on peanuts?

1. It can increase the yield of peanut.

Paclobutrazol belongs to internal absorption, and its efficacy can be absorbed by roots, stems and leaves, and the growth of crops can be regulated so that more nutrients are partially absorbed by flowers and fruits, thus increasing crop yield.

2. Improve the stress resistance of peanuts.

Spraying peanut plants with paclobutrazol solution can promote root growth and improve the ability of water and fertilizer absorption of roots. The volume of water storage cells in leaves increased, the transpiration rate decreased, and the water content of leaves increased. Spraying paclobutrazol could improve the drought resistance of peanut.

3. Regulating growth and development.

Seed dressing with appropriate amount of paclobutrazol can regulate the growth and development of symbiotic seedlings by soaking seeds for 1 hour and then drying and sowing in the field. The results showed that the basal internodes were shortened, the plant height decreased, the branches increased, the root activity increased, and the chlorophyll content and photosynthetic rate of leaves increased significantly.
