Bruno speculates that the reason why pyrethrum is sold at such a low price is probably because pyrethrum originally existed in this world.
In the days after traveling, Bruno observed all aspects of the world in detail, whether it was climate, vegetation, soil conditions, mineral types, social culture, he had a general exploration.
Except for the possession of magic, the social development trajectory and most biological species in this world are basically very similar to those on Earth. There may be some minor differences, but these differences are almost negligible.
The prices of goods in the system mall are also closely related to it.
For example, items that originally existed in this world are sold at very low prices.
Fruits and vegetables that already exist in this world, such as onions and beets, usually only require single-digit brilliance points.
Even the most precious magic crystal veins in the world can be purchased directly in the system mall with a mere twenty brilliance points.
However, things like three-masted sailboat blueprints, potatoes, corn, etc. that were not available in the world, or that Bruno had never discovered before, were ridiculously expensive.
It can be seen that the price of the system mall is not only marked according to its value and usefulness, but also closely related to the difficulty of obtaining it.
Take this pyrethrum for example. Because Bruno had seen a few sporadic flowers in the dense forest around the sky garden, the system judged it as a plant that originally existed in Idar Territory, so it was listed in the system mall
The price is extremely low.
Although the sea of pyrethrum flowers in front of him only consumed Bruno's five brilliance points, the role it played should never be underestimated.
With this piece of pyrethrum, the pest problem that has troubled the Idar people for many years can almost be said to be solved.
The inflorescence head of pyrethrum contains four insecticidal ingredients, among which pyrethrum has the most powerful insecticidal effect.
By extracting pyrethrins from pyrethrum, an extremely efficient natural broad-spectrum insecticide can be prepared, whose insecticidal toxicity is dozens of times more powerful than organochlorine, organophosphorus and other insecticides.
Its mechanism of action is to disrupt the normal physiology of insect nerves, causing them to go from excitement, spasm to paralysis and death.
At the same time, because the amount of pyrethrin required to prepare pesticides is small and the concentration used is low, it is safer for humans and livestock and causes little environmental pollution.
However, its disadvantage is that it is highly toxic to fish and harmful to certain beneficial insects. Long-term repeated use may also lead to insecticide resistance in pests.
However, Bruno does not care much about this so-called shortcoming, because compared with the contribution that this natural pesticide can make to Idarland, such shortcomings are almost negligible!
Since the cultivated land area of Idar Territory has more than doubled this year, most of the serfs in Idar Territory are tied to agricultural production, which makes Idar Territory's manpower for ship construction, new city expansion and road construction relatively tight.
.
Although the number of people entering the Idar Territory has been increasing in recent months due to the extensive publicity strategy of the Idar Territory, most of them are attracted by the land policy of the Idar Territory. To put it bluntly,
Came here for the farmland provided by the Idar Territory.
Therefore, although the population is growing rapidly, there is still not enough manpower to be sent to various places for construction projects.
And Bruno didn't intend to drag the civilians who came to live in Idar Territory after hearing the news to build those projects from the beginning. Since they wanted to farm, he would let them go.
Besides, after all, they have just moved here, the new civilians must first get used to the Idar Territory, which is completely different from other places in the empire.
Furthermore, if you have food in your hands, you won’t panic in your heart.
If war breaks out in the northern frontier of the empire, no one can tell how the situation will develop.
However, with enough food, Idar has enough confidence!
However, the cultivated land area of Idar Territory is effectively expanding, but the number of people engaged in agricultural production has increased dramatically!
If the same area of land was placed on the earth in the previous life, only two people would be needed to cultivate it, but here, it takes three to five people!
The most important reason why a large number of people are tied to the fields is because of pests!
In this era of magic but no druids, we can only rely on manpower to eliminate insects. To put it more bluntly, we rely on civilians and serfs to pull out the insects one by one with their hands.
!
It feels incredible? But this is what happened in Idar Territory!
If it is just to remove insects from a few crops planted in the yard, this method is acceptable to Bruno, but if it is placed in a vast farmland, this method of insect control is too inefficient!
Using pyrethrum to make a natural insecticide was the solution that Bruno came up with after hard work.
Once such pesticides are widely promoted and used in Idar territory, a large number of people will be liberated from the cultivated land!
Maybe even the manpower to build other wonders can be found!
Of course... this is just Bruno's random thought... After all, Idar's existing financial chain will never allow him to do this.
But there is no doubt that the production of pesticides will bring the agricultural development of Idarland to a new level.
The pesticide preparation workshop is built on the hillside where a large number of pyrethrums grow. It provides a complete one-stop service from picking to preparation, and even the transportation cost of raw materials is eliminated.
And when picking, the serfs only need to pick off the flowers, stems and leaves of the pyrethrum, while the roots can be left in the soil to continue growing. In this way, Bruno does not need to exchange the pyrethrum every year.
Although it only requires five Brilliance Points, it would still be a huge expense if you had to repurchase it every year.
As for the principle of making pesticides, Bruno has also copied it on paper and handed it to Shabi. The main purpose is to purify the pyrethrins contained in pyrethrum, and use them as raw materials to mix with solvents to make pesticides through a certain ratio.
.
Therefore, as long as you have enough pyrethrum, the next method will be much simpler.
While talking to Shabi about some precautions for making pesticides, the beggar's chicken on the side was also cooked at this time.
"You sit down and eat too." Bruno used a branch to pick out a beggar's chicken wrapped in mud from the charcoal fire, and said to Shabi.
"This...is not appropriate..." Shabi was obviously hesitant.
"I order you to sit down and eat chicken for me!"
