"Look, it's two parts water, one in pure alum, the bluer the better. Put the other part in quicklime and let the water submerge it. Don't stir, wait until it turns into a puree, then filter it with fine gauze, add a beaker of water, and make lime milk...... "Of course, Li Yaofu couldn't withstand the coercion and temptation of Hong Tao, the big bad wolf, and finally agreed to be the inventor of Bordeaux liquid with two other classmates. Then the three of them picked up the small notebook, watched Hong Tao operate on the spot, and recorded every word, every step, and every unit that Hong Tao said, which was the real reward.

Bordeaux liquid is a very simple compound, which is to prepare a copper sulfate solution with a concentration of about 80% with relatively pure bile alum and water, and then use quicklime to prepare lime milk with a concentration of about 10%. When used, it is prepared on site according to the ratio of one part of lime milk and nine parts of copper sulfate solution, and it can be sprayed on crops after dilution. But there is a problem with the order here, you must pour the copper sulfate solution into the lime milk, and you must not operate it the other way around, otherwise the solution will precipitate and fail.

"Go ahead, remember the preparation steps, just find a random sugarcane field and try it, just spray it directly on the leaves with a bamboo spray can. Remember to wash your hands, this is a pesticide, poisonous, eat diarrhea! Hong Tao didn't make much of it, only mixed two beakers of lime milk and copper sulfate solution, and then asked Li Yaofu and the three of them to try it in the sugarcane field to see if this sky-blue potion worked.

The reason why he didn't go by himself was because he was a chicken thief. If no one had discovered the test, the Bordeaux liquid would have not worked. It doesn't matter if someone finds out, the little apprentice tries to play, and the dead horse becomes a live horse doctor, and it's normal to fail. I didn't see that the master didn't follow, which shows that I am not optimistic about it.

It is certainly impossible not to be discovered. Almost all the workers on the farm stayed in the fields, and even their families came. They are still clinging to the last ray of hope, hoping that God will rain heavily or something, maybe the condition will be cured, and if they can't burn it, don't burn it. Everyone didn't care about Li Yaofu's three children holding small bamboo tubes and spraying them on the crops. It's all things that are going to be burned, so let's do whatever you like.

Pesticides are not explosives, and the effect cannot be immediately apparent, so Hong Tao sent the three children to spray the pesticides, and then went home by himself. It's not been a good few days, and he plans to go to Qi Zu tomorrow to find a balance. This old man can always surprise himself, and if he really doesn't have it, he will go to take a few shots to have a good time, and practice his marksmanship by the way. Why is that guy Swann better than himself, this is not scientific.

It's a pity that I arrived at Qi Zu the next day. Before he could make a few shots, Ciqi ran over out of breath and called him back to the north shore. said that Huang Hai was leading people to break into the secret laboratory of the chemical group, and the police couldn't stop it, so they had to let Hong Tao go over to calm down.

"Do you know what Lao Huang is for?" Hong Tao and Ciqi rode horses and played drums in their hearts while hurrying, wondering how it was related to Li Yaofu and their trip to the sugarcane field yesterday to test Bordeaux liquid. Don't mismatch yourself and poison all the crops in the Yellow Sea.

"He said he was looking for your apprentice, but the policeman in charge of standing guard saw him rushing in with so many people. I didn't dare to let them in, so I quarreled. I didn't dare show my face. Lao Huang doesn't like to take care of me very much, he may not be too excited without me, once I go, maybe he will have to do it, so I'll find you first. "The cost-effective ciqi didn't go to the scene either, he planned to pull Hong Tao as a shield.

"You're a thief. In the future, try not to mess with these old guys, they are the heroes of Jinhewan, and they are older, let them live comfortably in their old age. Those who can open their eyes and close their eyes pretend not to see, but there is a principle. It can't have too much impact, and it can't clearly violate national laws, that's my bottom line. You must grasp this degree, if this kind of thing happens and you don't care, then I will deal with you first! ”

Hong Tao didn't blame Ciqi for being cowardly, his approach was more in line with his own heart. Huang Hai, Bo Fu, Chen Mingen, Wen Laoda, and Wen Laoer have involuntarily regarded them as the heroes of Jinhewan, and as they get older, their style of acting has become more and more arrogant.

Slave-born imperial officials like Ciqi are not very much in their eyes, especially the brothers Ciqi and Cixi, who are very few people in the empire. But as long as they don't break the law, Hong Tao doesn't plan to be serious with them. They can live for a few more years, they have worked hard for Jinhewan for more than ten years, and they are indeed heroes, even if they are a little out of line, they can endure it.

"I understand, I understand...... Ciqi was very moved, to meet such an understanding boss, it is a blessing for subordinates, more cost-effective than how much bonus is given.

When Hong Tao arrived at the gate of the chemical group, there was no physical confrontation between the police and the farm workers brought by Huang Hai, because Weng's family also heard the news and rushed out of the factory to persuade them to fight. Huang Hai couldn't be unreasonable in the face of his family, so he had to sit at the gate and wait for Hong Tao to deal with it. The Weng family didn't dare to let him enter the small courtyard of the laboratory, this courtyard had the highest level of secrecy, except for Hong Tao and relevant personnel with work certificates, no one could enter, even if Bozhu came, it was useless.

"Yo, Uncle Huang, don't hurry home and cook at noon, which one is this singing!" Hong Tao will always be hippie and smiling when dealing with these old people, no matter what you say, as long as you don't scold your ancestors in front of you, he won't be angry.

"I'm still eating, I'm dying! What about the little guys who went to the sugarcane fields yesterday to spray pesticides? You call them out. "Huang Hai's hair is white, his back is hunched, and his teeth are missing, but his voice is not small at all, and he is still very confident.

"Can you tell me what you're looking for them? They are all children who have just graduated for less than two years, your situation is a little too scary, but you are also my apprentice, if you have any problems, you can tell me first, and I will go back and criticize them? Hong Tao has already made up his mind, if it is really Li Yaofu and they poisoned the crops, then he can only be used as a shield. The idea is made by himself, and the potion is also prepared by himself, and he can give it to his apprentices with credit, but he can't let it go if something goes wrong, so he is still human.

"Hi...... I won't let you follow, you have to follow, and you don't fight, so many people don't get me wrong! Xiao Tao, those three boys are so capable, the sugarcane field they sprayed yesterday has been visited today, guess what? The leaves no longer rust. I'm here to ask them to continue spraying, the same blue-watery potion from yesterday. Huang Hai realized that it was a little inappropriate for him to be followed by a large group of people, wiped the sweat from his head, took a sugarcane seedling from a worker next to him, and pointed to the rust spots on the leaves and talked about his intentions.

"Are you sure it works? How can you see it? Now it's Hong Tao's turn to be a little surprised, is Bordeaux liquid really so powerful? It was sprayed yesterday afternoon, and it took effect at noon today? This thing must be asked, don't be mistaken.

"I promise it works, I'm in charge of this field, and I know how many leaves are sick on which tree. When I went to see it this morning, not only did the bad leaves get sick, but the rust spots on the sick leaves didn't expand, and the color became darker, as if the piece had died. A dark and thin middle-aged man stood behind Huang Hai and told Hong Tao in detail the basis for his judgment that the potion worked.

"That's right...... Uncle Huang, you take someone back first, prepare more bamboo spray cans, and then find a few large wooden barrels filled with water and put them on the edge of the field. I went back to the lab and watched them make the potion out first, and then send it to the edge of the field for everyone to spray together. Call everyone you can call and try to spray all the fields today and see the results. After listening to the description of this farm worker, Hong Tao felt a little bottom in his heart, it seems that the Bordeaux liquid has played a role, at least the condition is controlled. So what are you waiting for, spray it quickly! If we can control the disease one day earlier, we can reduce some losses, and if we can really eliminate the disease, this year's production will not drop too much.

Hong Tao spent this day on the edge of the field, he still didn't worry about Li Yaofu and their independent dispensing, let alone those farm workers who had never used pesticides, kept telling everyone not to let pesticides stick to the skin for too long, and quickly rinse with water if they got wet, and forced everyone to wear masks made of cotton. Bordeaux liquid is also a poison no matter how low toxicity and less residue is, so you must be careful in operation.

"Do these blue potions really work?" After a busy day's work, Hong Tao ran to his imperial village with two jars of liquid medicine in the evening, and took Bai Xiang and several of her Li families to spray their tobacco fields, and then they were so tired that they couldn't straighten their waists. Don't look at the dragon and tiger on the battleship, he is more energetic than anyone else, but when he does farm work, he is really not as good as worshipping incense, and the interlacing is like a mountain.

"It works, I tried it on the farm yesterday, you can come and see it tomorrow, if these rust spots don't continue to increase, it means that it is useful, spray it again in a few days, and the disease of the crops will be cured." Hong Tao had already sat on the ridge of the field, and he didn't want to move at all, only his mouth was still alive.

"Hey, hey, hey...... That day, I said to you in front of the big guy, don't be angry, I'll change it in the future, Bozhu has already scolded me...... "Hearing that the tobacco field was saved, Bai Xiang was in a good mood, and he also knew that he was a little too much to Hong Tao a few days ago, so he took the initiative to apologize."

"It's okay, it's common for couples to quarrel, I'm often not at home, at home and abroad, children and the elderly rely on you to take care of them, don't be afraid of being scolded if you work less, it's fair." Bai Xiang can take the initiative to admit his mistakes, Hong Tao is very pleased, his wife can be reasonable, it is God's favor to him.
