Pest infestations generally occur in hot, dry or humid and dark environments.

Liu Su listened to Liu's father's description and judged that the orchids of Master Fu's house should have given birth to aphids. These pests are white and small, looking like white powder from a distance, and up close, you can see that they are just small white insects that are very small. They like to hide on the back of the leaves, eroding the leaves. At some point, it will start to erode the entire plant.

In the beginning, because of its small size, it was difficult for people to find out because of its small size and hiding. When the pieces appear, you can only use pesticides if you want to get rid of them.

In fact, if you find it early, you only need to isolate the plant and prune off the leaves of the insects. The whole plant can survive. Liu Su thought for a moment.

"Father, don't worry, things will always work out. We'll go early tomorrow in the morning. Liu Su comforted.

"Su'er, you go play, father has to think about it. Wait until your father calls you to dinner. Father Liu's heart was full of sorrow.

"All right, father. I'll go with my brother and deal with these herbs first. I'll come to dinner with my father later. Liu Su gave a salute after speaking.

"Master, I'm going to help my sister." Zhao Yi then came out.

Liu Su and Zhao Yi came to the backyard of the inn. I borrowed some coarse cloth and fine wire scissors from the shopkeeper and dug some soil. On the stone table of the Eight Treasure Pavilion in the backyard, the herbs picked up were laid. "Senior brother, first clean up the leaves on each herb and leave only 3-6 leaves, leaving only the old leaves that are not damaged. Then dig some moist soil to wrap the roots, and then use a cloth to pick up the soil and the roots, and tie a knot with a thin thread.

You see, that's it. Liu Su took out a bead of herbs and demonstrated it to Zhao Yi.

Zhao Yi looked at it very seriously. Then you'll be able to get started on your own. "Senior sister, can this really keep these herbs for so long?"

"Yes, although there is some damage, but most of it can survive." Liu Su said very confidently.

"Senior sister, you know a lot. Is this what the master taught you? I'm too stupid, and I don't have a master to teach me. Zhao Yi said with some envy.

"Senior brother, don't think about it, my father didn't teach me this. This is what I thought of myself. As soon as Liu Su heard this, he knew that this senior brother was thinking nonsense.

"Really, the junior sister is not the master's daughter. How clever! Zhao Yi touched his head a little embarrassed. Because he had mud on his hands, he made a lot of mud from his hair.

"Haha... Senior brother, you are really, don't move, don't move. I'll wipe it off for you. Liu Su looked at it straightly. wiped his hands with an unused coarse cloth, took out a handkerchief from his arms, and carefully wiped Zhao Yi's hair.

Liu Su did it naturally, but she didn't see Zhao Yi at the moment when she approached. His body stiffened, and his face flushed. A good smell came from the surface.

"Thank you... Thank you, sister. Zhao Yi's voice of thanks was as small as a mosquito.

"Senior brother, you're welcome, it's nothing. Let's finish this quickly, and go to dinner with my father. Liu Su was not embarrassed at all. She smiled and withdrew her handkerchief and went back to work.

After the three of them finished eating that night, Liu Su simply washed up and went into the back room alone, and Zhao Yi slept with Liu's father outside. Although the door was closed, Liu Su could still hear Liu's father's sigh and Zhao Yi's relieved voice beside him.

At the beginning of the next day, the sound of Liu's father shouting to Xiao Er to fetch water came from outside. Liu Su hurriedly got up and freshened up with the cold water left over from last night. Open the door and go out inside.

After the three of them had a simple breakfast, Father Liu rushed to Fu's mansion with the two of them.

A quarter of an hour later, an antique five-entry mansion appeared in front of Liu Su. Two mighty and domineering stone lions stood at the door. At the head of the door hangs a door plaque made of good sandalwood "Fu Fu".

Master Fu was born in the capital city of Le'an, one of the four great families that has been inherited for a hundred years, and is known as Fu Sanye. Because Liushui County is located in the north-south water traffic fortress, although it is a county, it is prosperous and not inferior to Chencang Prefecture. It is even more important than Chencang Prefecture in terms of political structure. After all, the current Song Kingdom is committed to discovering the shipbuilding industry. I heard that there is a secret shipyard in Liushui County. There is always a reason why the Fu family, who wants to come to the four great families, let the third master of the Yan branch come to this Liushui County to be a magistrate.

Father Liu came to the door and whispered to the doorkeeper to explain his intentions. After a while, a small corner door opened next to the gate. A man in his 40s who looked like a steward walked out.

"Master Liu, you're here, come in quickly. My lord is so anxious. I've asked a few times. I looked at that little worm this morning more than it did yesterday. ”

"Steward Fu, you take me to see it first. I also thought of a solution overnight. Father Liu bent down to Steward Fu and saluted. Zhao Yi and Liu Su had to bow first.

Walking into the Fu Mansion, Steward Fu took the three of them through the front yard, through the corridor, and through the three hanging flower doors before coming to the back garden of the inner courtyard.

Liu Su followed the hurried all the way, but he didn't forget to look around at the courtyard of this ancient rich and noble official. Although I have also visited Suzhou gardens and historical palaces in my previous life. But it still can't make her as excited as she sees it now. It is really exquisite everywhere, and it shows the heritage of the family everywhere.

Liu Su is still indulging in the low-key luxury of this ancient family. I heard Steward Fu say, "Master Liu, you see, this Mo Lan is even more out of vitality than yesterday. There are more white bugs on it than yesterday. And over there, the petal orchid, phalaenopsis, Jianlan, emerald orchid, spring orchid, and Huilan are all similar situations. And the pot of Junzi Orchid that the master personally took care of was even worse, and the whole plant was crawling with white insects. The old man didn't dare to put it in the house, and now he also placed it there. ”

Steward Fu pointed with his hand, and Liu Su followed to look over. It is true that there is an infestation of aphids. Only small white dots are visible throughout the plant, and the green leaves have been thickly covered by insects.

"Father, how do you deal with this situation?" Liu Su was also frightened by this gentleman's orchid full of aphids.

"Usually when encountering such a situation, one is to catch the pests, if there are more pests, let chickens, ducks, birds and other animals catch and eat. Or cut off the leaves of the pests. When Liu's father heard his daughter's question, he answered in detail.

As soon as Liu Su heard this, he knew that there was no special way to deal with these pests in ancient times. Liu Su thought for a while, walked away from Liu's father, and carefully observed the situation of these orchid pests.

After watching it for a long time, Liu Su understood that this was a second-level pest, and that Junzi Lan had reached the third level. If no effective treatment is provided, all these orchids will be eroded by insect pests and die.

"Father, do you have any effective methods to control pests now? For two days at most, all the orchids here will be covered with this white worm just like that gentleman's orchid.

When these insects have destroyed the orchids, they will sweep through the flowers and trees of the entire Fu Mansion. They are contagious. Liu Su explained.

Steward Fu next to him was shocked when he heard that the flowers and trees in the entire house were going to be affected. "Master Liu, you should think of a way. If all the flowers and trees in the yard of the ladies and ladies are infected with pests, then my old bones will really be chopped up to make flower fertilizer. Steward Fu was very frightened, he really didn't expect that a little insect would cause such serious consequences.

"Steward Fu, it's really not that I'm not willing to help, it's too serious. I can't find a suitable way for a while......" Father Liu hasn't finished speaking.

Liu Su gently pulled down Liu's father's sleeve. "Father, didn't you say last time that boiling garlic in water can kill insects? Why don't you try it, father. Liu Su took Liu's father's words.

Father Liu was stunned for a moment, he couldn't remember when he said this.

Seeing this, Liu Su kicked Zhao Yi with his foot and motioned for him to speak with his eyes. "Yes, master, we succeeded in the experiment last time. This time it will definitely be okay. Zhao Yi was very practical, and then said Liu Su's words.
