There are various types of peanut control agents. How to choose suitable peanut control agents?

At present, there are many growth-controlling growth regulators used in agricultural production, such as meperidine, Yudan, anti-inverted fat, furol, paclobutrazol, uniconazole, dwarf, metopromam and so on. So far, some of them have been eliminated, and most of them are still widely used. As far as the general classification is concerned, most of the strength control agents belong to triazoles.

Although the growth control effect of triazole growth regulators is also good, but the duration of the effect is too long, the agricultural residue is high, and the harm to the following crops is serious. However, calcium cyclate overcomes the above problems. Under the premise of efficient inhibition of crop growth, there is no agricultural residue and no pollution to the rotation crops.

Although quaternary ammonium salts (dwarf, methylpiperonium), triazoles (paclobutrazol, uniconazole) and cyclohexane carboxylic acids (calcium cyclate, anti-inverted ester) can inhibit gibberellin biosynthesis by regulation, so as to control crop growth, promote photosynthetic metabolism and increase crop yield, however, calcium cyclate can be said to be a rising star, and its advantages have been gradually reflected in production. It is more welcomed by the market and has a wider application prospect.

Calcium cyclophosphate, as an efficient plant growth regulator, is also very efficient in regulating plant growth. the regulator was synthesized in Japan in 1983 and used in Gramineae and fruits and vegetables, and the drug has also applied for patent protection in China. This is also a widely used cyclohexane carboxylic acid compound.

After the application of calcium cyclophosphate, the leaf color turned green and the thickness was improved obviously, which improved the photosynthetic efficiency of peanut and achieved the purpose of increasing yield. Some studies showed that after spraying calcium cyclate and paclobutrazol, there was little difference in photosynthesis between the two groups in the first week after spraying, but in the second week, the photosynthetic efficiency of calcium cyclate group was much higher than that of paclobutrazol group.

Compared with paclobutrazol, after spraying calcium cyclophosphamide, the senescence rate of peanuts is slower in the later stage, while paclobutrazol or dwarfin peanuts tend to show the symptoms of premature senility, which is also a major advantage of calcium cyclophosphamide in this respect. Calcium cyclate can significantly improve the root activity of peanut and avoid or delay premature senescence.

In terms of yield, calcium cyclate treatment was not weaker than paclobutrazol treatment group, but in terms of growth control effect, calcium cyclate seemed to be inferior to paclobutrazol, but the pod weight, dry matter weight and yield of the plant were excellent. The effect of increasing yield was significantly better than that of paclobutrazol.

To sum up, people in the selection of peanut growth control science suggested to consider calcium cyclate, dare not say that this is the best peanut growth control regulator, but in terms of the current production is a very good choice.
