In the morning, Li Lianzhu sorted out the accounts in the house, preparing to go to the account when he returned to the bun shop. Shi'er and the others still went to the vegetable field, and now the weeds in the field are growing very much and need to be pulled out manually, which is also a very time-consuming and laborious work.

Just as Li Lianzhu was concentrating on calculating the accounts, Junzi suddenly ran into the courtyard and entered the house without knocking on the door.

Li Lianzhu frowned, and was about to reprimand him for a few words, but Shunzi took a big breath, but said first:

"Brother Tie Zhu, there are greasy insects in the ground, it's a big piece."

Li Lianzhu was shocked, he hadn't seen much of this yesterday, why did it suddenly flood?

"Is it all growing in the ground?" He asked Junko.

"There are no leek fields, there are others, and the small rape grows the most." Junko wiped the sweat from her forehead with her hand.

Leeks have a peculiar smell that many kinds of pests don't like, so they are spared.

"Let's go, we'll see." Li Lianzhu put down the accounts in his hand, locked the door and discharged from the hospital, and walked quickly to the field with Junzi.

When they arrived in the field, Li Lianzhu asked the others not to stop what they were doing, and he and Junzi came to the small rape field that was the most severely affected, approached and squatted to take a look, and sure enough, many tender green rape leaves were densely covered with gray dots, and they were still squirming if they looked closely.

Greasy insects, whose scientific name is aphids, belong to the family of homoptera aphids, are pests of stinging and sucking mouthparts, often clustered on leaves, young stems, flower buds, terminal buds and other parts, stinging and sucking sap.

Li Lianzhu knew that this was a common pest in the field, which grew and reproduced very quickly, but this time the reproduction speed exceeded his previous experience, but after thinking about it, it was estimated that the nutritional content of this special vegetable was quite good, which promoted the reproduction and development of greasy insects.

Greasy insects also have a characteristic, they will secrete sweet honeydew, attract ants and so on.

Immediate action must be taken, otherwise the leaves of the vegetables will quickly curl up, shrink and even cause the whole plant to die.

"Junko, hurry up and go to the agricultural material store in the village to buy a few bottles of pesticides, sprayers and masks." Li Lianzhu took out a few hundred yuan from his pocket and handed it to Shunzi.

Junko took the money and answered, turned around and left.

Li Lianzhu suddenly thought that something was wrong, and Ranzi repeatedly explained to him that the vegetable base focuses on the concept of natural green, and pesticides and fertilizers must not be used.

"Junko, come back." He hurriedly called out to Junzi, who had already run more than twenty meters away.

Junzi returned suspiciously, and couldn't help but be anxious after hearing the reason explained by Li Lianzhu.

"Brother Lianzhu, we all met this in our hometown, how can we get rid of it without medicine. You can't catch it with your hands, can you? If only the cabbage worm is about the same. ”

"Don't worry, let me think." Li Lianzhu's face was solemn, squatting on the ridge and looking at the vegetable leaves.

Over the years, the use of pesticides has become widespread, and when encountering insect pests, almost no one considers other methods. As a result, the resistance of pests has been increasing from generation to generation, and the toxicity of the corresponding pesticides has also increased, resulting in the problem of residues that cannot be fundamentally solved.

As for biological control and the like, it has always been thunder and rain, and it is easy to set up research projects, but it is difficult to achieve actual results, so it can only be limited to a very small range.

I've heard that some people used smoke to prevent insects many years ago, and it's a good idea, but smoking requires a lot of wormwood, and there's nowhere to find it.

Thinking about it again, Li Lianzhu stood up and paced back and forth along the ridge.

Junko stood to the side, staring at him with blank eyes.

Finally, Li Zhuzhu stopped and said to Junzi:

"Shunzi, you go to the small bazaar and buy ten catties of dried chili peppers and two catties of peppercorns. By the way, you have to pick up the hottest peppers and buy them, and the best ones are Chaotian peppers. ”

"Brother Lianzhu, on this hot day, you want to eat spicy hot pot?" Junko asked puzzled.

"Eat a hot pot with P, it's for insect control, hurry up and buy it, where is so much nonsense!" Li Zhuzhu shouted impatiently.

Junko muttered a few words and trotted away in the direction of the village.

Half an hour later, in the kitchen of their residence, Li Lianzhu and Junzi set a large boiling pot filled with three-quarters of cold water on the stove, lit a fire, and then added a large handful of dried chili peppers. Start boiling the chili peppers

On the other stove, use a smaller pot to boil pepper water.

As time passed, the air in the kitchen filled the air with the choking smell of chili peppers. Li and the others dipped their newly bought masks in cold water, put them on their faces, and then kept stirring them in the pot with a spoon.

Shunzi bought the most expensive Chaotian pepper, spicy enough, the taste rushed out of the kitchen, and after a while, the old man of the landlord was also invited, Li Lianzhu hurriedly agreed to cover the pot, and the window was closed, so the old man of the landlord who was muttering was sent away. …,

After boiling a pot of water for forty minutes, the two poured the chili water into the prepared iron bucket to cool, and then continued to boil the next pot.

Near noon, the first batch of chili water and pepper water was finally completed.

But the sun is too strong at noon, and it is not a good time to take medicine, and you can't do it until the afternoon.

So I had to do something else first.

At half past five in the afternoon, Li Zhuzhu led his subordinates to return to the vegetable field with large and small buckets of chili water and pepper water. Although it was close to evening, it was a summer day and the light was still bright.

"Brother Lianzhu, can this chili water kill insects? How come I haven't heard of it before? Shi'er asked.

"There's a lot of things you haven't heard of, this time let your kid learn a hand." Li Lianzhu came to the edge of the small rape field, put down the bucket, took a small broom, reached into the bucket and dipped it in the chili water, and then shook his hand, scattered the chili water and threw it on the nearby small rape trees.

Junko and the others hurried closer to watch, and after a while, they all exclaimed.

"It really worked, the bugs are all in a mess." "That's amazing."

Li Lianzhu also stepped forward to check, only to see that wherever the pepper water went, the greasy insects shrank into a ball, constantly struggling, and the effect of spraying pesticides was almost the same.

He finally breathed a sigh of relief.

It seems that the soil method has not failed, and the resistance of pests has been greatly improved over the years, but the ability to resist pepper water has obviously not improved. It's no wonder who still uses this time-consuming and laborious method now.

This method was something he had heard from his father when he was a child, and he finally remembered it in the morning, but he didn't know if it would work at the time.

The experiment was successful, so he commanded his subordinates to bring a few brooms and pepper water in the bucket to greet the vegetable patch.

It's okay to do this job with a scoop of water, but it's too wasteful and unevenly sprinkled.

In this way, the five of them were busy until the sky was full of stars, and the water in the bucket was consumed. It's hard to see now, and the exact effect won't be known until tomorrow morning.

Junko moved her sore arm, and then she remembered that she had forgotten to leave someone to cook dinner today. He hurriedly told Li Lianzhu about this.

"It's okay, everyone has worked hard today, let's go to the restaurant in the evening, and the wine and meat are enough." Li Lianzhu waved his hand and said boldly.

The boys cheered in unison, and the sound startled the birds perched in the trees by the roadside.

Early the next morning, everyone hurried to the field to check the effect of last night's insect control, not surprisingly, most of the greasy insects were killed, and the effect of pepper water with pepper water was satisfactory.

So, Li Lianzhu arranged the work, and if he boiled it again today, it was estimated that he would be able to completely defeat the insects. Clear
