Paclobutrazol is often used in peanut control, but do you really use it correctly?

Paclobutrazol (paclobutrazol) is a kind of plant growth regulator commonly used in agricultural production. Because of its endotropy, its efficacy can be absorbed by roots, stems and leaves and regulate the growth of crops. However, for the use of paclobutrazol, we should also pay attention to the following matters: the principle of use, the time of use, the amount of medicine used, the skills of use and so on. The following scientific promotion of agriculture in view of the above aspects to introduce several problems in the use of peanut paclobutrazol.

Principle of use

On the use of paclobutrazol, or according to the growth status of peanuts to use, the purpose is to promote plant growth and development, control growth, and the use of too much medicine, it will affect the growth and development of plants, therefore, for the use of paclobutrazol, or as little as possible!

For the whole growth period of peanut, it is usually chosen to spray paclobutrazol two or three times, without excessive application of paclobutrazol, and avoid large amounts of application.

Use time of paclobutrazol

In fact, there is no accurate statement about the time of application of peanut paclobutrazol. It is generally said that it needs to be applied when the plant is about 35-40 cm, but this is also relatively general. From the point of view of the purpose of controlling prosperity, it is still to promote flowers and protect fruit, so the application effect is better when the peanut needle is pricked, when the peanut has just withered, and after controlling prosperity, nutrition is concentrated on the supply of fruit needle. It is beneficial to the expansion of peanut fruit!

However, at the beginning, we also mentioned that the use of paclobutrazol is based on the growth of the plant, without the actual use of drugs is difficult to obtain high yield. For example, at the seedling stage, if the growth is too weak, low concentrations of paclobutrazol can be used to squat seedlings to make the roots of seedlings more robust and improve the stress resistance of plants.

If used in the flowering stage, it can promote the development of lateral branches, increase the number of fruit needles, and play a role in preventing premature senility, thus increasing the yield of peanut.

Concentration of paclobutrazol

In this respect, in fact, there is no fixed standard, as mentioned above, we must pay attention to the use of high concentration, and low concentration will not be ineffective, so we must consult the instructions again and again when using them, according to the instructions to use the medicine, usually the dosage is 250-350 times dilution.

Basically, these are the problems with the use of paclobutrazol, but scientific agriculture still wants to mention a few small precautions. For example, farmland may grow weakly in some areas due to fertilization or uneven soil fertility. For such peanuts, we must pay attention to avoid. For example, when spraying, the surface tension of paclobutrazol will be greatly enhanced if some washing powder or detergent is added to the medicine, which can greatly improve the adhesion of the spray and greatly improve the effect of drug use.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
