This kind of experiment requires enough time, even if this world has extraordinary power. So in the next week, Lawrence used this time to test a series of experiments on the farm while reading the books carried in the space bag.
Soil pesticides.
Fortunately for him, after his soul merged and became the Bai Ze Warlock, his strengthened soul allowed him to recall everything in his two lives. This included a large number of various things he had prepared for writing novels.
The information, and even some pictures that were only viewed on the computer screen for less than a second, were accurately recalled.
Among so many materials, there are many materials prepared for writing historical novels. Although most of them are not of much use in this industrial era, the differences between different worlds make some of the materials stand out immediately.
Considering that the chemical industry in this world is at a low level, and using the extraordinary power of extraordinary beings to bypass industrial level restrictions would be too expensive to be popularized, so all Lawrence was experimenting with during this period were local pesticides found in a book in the 1970s.
.The good news is that they have achieved good results in recent experiments.
These pesticides are naturally not as effective as those industrially produced formal pesticides, but they are much better than the pesticides currently on the market. At the same time, they are just in line with the world's industrial level and can be produced cheaply and on a large scale. In addition to Bordeaux mixture, there are also lime sulfur
Mixture, pine-base mixture, white paint used to brush tree trunks in winter, and sticky glue made from tung oil, rosin, and yellow wax.
"I feel that the agricultural church in this world has completely misunderstood the technology of pesticides." After the coachman who went back to the church brought his reply letter to Saphire and a letter to Priest Carter back to the city, Lawrence replied
When I arrived at the laboratory, I began to examine a series of pesticides bought from the Agricultural Church yesterday. I also thought: "Maybe because the goddess of agriculture is the daughter of the Mother Earth and the Father of Nature, all the pesticides used by the church are plant-based."
"
"There are a lot of plant-based medicines, but many of them are not very effective." Thinking of this, Lawrence remembered some stories about the Agricultural Church that the staff member of the Knowledge Church told him yesterday, "Faced with this situation, the Agricultural Church
The solution turns out to be harnessing supernatural power."
"For example, this bottle is similar to pyrethroids on Earth." Lawrence took out a red bottle from the pile of potions on the table, briefly tested it, and then looked at the label on the bottle. "
On earth, this kind of thing is synthesized through the chemical industry, but here, the priests and druids of the church repeatedly improved the plants to produce this substance, and then used magical means to purify it."
"I have to admit that the effect of this medicine is indeed very good, and it does little harm to humans and animals. But just the 500ml of medicine on hand costs 10 yuan, which is equivalent to a month's salary of an ordinary worker. So these medicines they only have
It can be used for the cultivation of some magical plants and the gardens of nobles."
As for ordinary farmers and farm workers in nearby farms, they can only use some plant ash or quicklime or dig out and burn seriously diseased plants. However, it is obvious that these have little effect on the current grape diseases.
Fortunately, after this week of testing, the efficacy of Bordeaux mixture has been demonstrated. Although the grape downy mildew in this world is somewhat different from that on the earth, especially the speed of spread and infection is much faster than that of the same kind on the earth.
.But these corresponding molds are more vulnerable to Bordeaux liquid than those on earth. At least in this week's experiments in the vineyards, these chemicals not only inhibited the continued spread of downy mildew, but even prevented previously infected downy mildew.
The diseased cane is restored to health.
"The next step is to disseminate the summarized knowledge," Lawrence thought after calling Shu Mei to start recording the experimental data and adding it to the paper. "I hope Priest Carter can reply quickly and tell me what to do next.
.”
"Huh? What happened?" After adding today's data at the end of the paper, Lawrence took out the alchemy book he borrowed before departure from his space bag and prepared to read for a while, but there was a loud noise outside the window. Originally, he had
I thought that the noise would disappear quickly, but I didn't expect that after a few minutes, the noise did not disappear but became louder and louder.
After opening the window and looking down, Lawrence found seven or eight people gathered in the empty field in front of the small building. Among them was a wounded man lying on a stretcher covered in blood.
"Let's go, let's go." Lawrence carried his medical kit and separated from the group of people gathered together. He half-knelt beside the stretcher and treated the wounded's wounds. "I graduated from medical school and am better at this kind of work.
.”
"Is there a goblin nearby?" Lawrence used a pair of scissors to cut open the clothing at the wound and took a look at it. He immediately recognized what the wound was about. After all, the town where he had lived for more than ten years had been plagued by goblins every year.
As a man who had helped his adoptive father treat wounded people since he was seven years old, Lawrence could easily tell how the wounds on this man's body were caused.
"Goblin?" As soon as Lawrence finished speaking, an old man with a gray beard next to him made a surprised voice. "This is impossible. The last time there was a goblin in the local area was nearly 20 years ago. Young man, you
Could it be that I saw it wrong?”
Others also showed expressions of disbelief, because this place is considered a suburb of the city. Under normal circumstances, the armed forces and various defensive magic circles in the city have a powerful deterrent effect on these creatures. Therefore, those disgusting
Theoretically, extraordinary creatures will not approach cities.
"I can't be wrong. After all, my hometown is in a small town along the Continental Railway. There are goblins in that place every year. Since I was seven years old, I have been helping my father deal with the injured when goblins happen. So
Over the years, I have treated at least 100 people who were injured in battles with goblins, so I should not be mistaken in judging the wounds."
Seeing that no one around him believed what he was saying, Lawrence cited what he had experienced as a child as an example. At the same time, he inserted a silver-plated steel probe into the wound according to the standard procedure for treating wounds. The result was unexpected.
What happened was that he felt the tip of the probe in his hand hit something hard in a large wound on the wounded man's buttocks.
Lawrence poked and pricked several times and found that the hard object was not touching the bone but looked like some kind of hard object, so he inserted a pointed tweezers into the wound. After testing a few times, he pulled out a half-coin-sized piece from inside.
black irregular metal.
"What is this?" The people around also saw this scene, and then the middle-aged uncle who didn't really believe in Lawrence's judgment spoke up and asked for everyone.
"Arrow." Lawrence said while treating the last few wounds. "To be precise, this is a copper arrowhead used by goblins. We are in big trouble this time."
"You are right." The staff member of the Knowledge Church took the piece of golden metal and looked at it and said, "Only goblin tribes with more than 500 people will have blacksmiths, and only those with more than 1,000 people will have blacksmiths.
Will cast some metal consumables similar to metal arrows.”
"You mean there are at least 1,000 brown and green-skinned guys around here?" The middle-aged man with a gray beard was startled at first, and then showed a confused look. "But we are in the suburbs of the city.
There are at most a few small hills and woods in the plain, and there is no place to hide at all. If there are really so many goblins, where would they hide?"
"I don't think there will be any goblins on the ground in this place, otherwise they would have been discovered long ago." At this time, Lawrence finished treating the wounded man's wounds and stood up. If nothing happens, the wounded man will recover. "But underground
