Plant growth regulator is a kind of regulator used by many farmers in planting. Many farmers only know that using it can increase production, but they do not fully grasp the correct method of use, and often fail to achieve the expected effect.
Recently, there was a peanut grower who wanted to make some three-time medicine for peanuts. The advantage of self-preparation is that you can choose different formulas according to the growth conditions of your peanuts, and you can save the cost of buying medicines, but the disadvantage is that you don’t know that some medicines cannot mixed. The farmer wrote a recipe himself, which contains fungicides, nutrient foliar fertilizers, and plant growth regulators.
To achieve high yields of cotton and peanuts, one of the most important parts is to control blooms. Generally, bloom control agents are added to the second peanut medicine, such as chlormequat, paclobutrazol, and uniconazole. The farmer asked: Brassinolide Can it be mixed with anti-prosperity agent? Some people say it can, others say it can't, and I can't tell the difference.
Brassinolide is hailed as the sixth largest natural regulator in the plant world by the international plant physiology community. The other five categories are gibberellin, auxin, cytokinin, abscisic acid, and ethylene. except).
Both brassinolide and thriving control agents are commonly used regulators, among which brassinolide is mainly used to promote crop growth, delay plant aging, and improve plant stress resistance. It has a similar effect to gibberellin . For example, it can be used on field crops to promote tillering, increase seed setting rate, and increase yield.
The overgrowth control agents include paclobutrazol, uniconazole, and chlormequat. The functions of these agents are to inhibit plant growth, promote flower bud differentiation, and increase fruiting rate. Their main function is to inhibit the synthesis of gibberellins.
There is a lot of rain in summer, a large amount of fertilizer is used, and the soil conditions are good. Peanut plants tend to grow vigorously, which is not conducive to peanut needle setting and pod formation, and the yield is also reduced. When the plant exceeds 40 centimeters, it is necessary to control the growth of the plant. Nowadays, Uniconazole is commonly used, which is safe, has good growth control effect and inhibits the growth of the plant.
If brassinolide is added, the two have opposite effects. After mixed use, the original prosperity control effect may not be achieved, but it is a waste of money.
Some farmers are worried that excessive use of growth control agents will cause the plants to stop growing, and they also need to use phytohormones for regulation. Will the mixture of brassinolide and growth control agents prevent phytotoxicity? Nowadays, there are also some pharmaceuticals that are a combination of brassinolide and unconazole, which are commonly used on fruit trees. However, it is not recommended to mix the two directly together. If you want to control the growth, it is recommended to use the growth control agent alone, as long as it is If used correctly and the concentration is well controlled, there will generally be no over-control, and there is no need to add brassinolide.
So, friends, must pay attention to the problem of chemical mixing when spraying foliar fertilizers, so as not to spend money and effort, but fail to achieve the effect. When using the flourishing control agent, we should also pay attention to the dosage. If the dosage is too large each time, it will inhibit the growth of crops.
