Tang Shenyuan told Professor Wu Shengming about the situation in the greenhouse vegetables on the phone, and after pondering for a few minutes, he said:

"You can't use pesticides, but there are many ways to kill insects......

Listen, this is what knowledgeable and literate people say, and when you are helpless, there are many ways to open your mouth, and you can't help but admire others!

"What's the solution?" Tang Shenyuan asked.

"I have five ways to do it here......"

There are five ways to test, but I don't have any of them. Tang Shenyuan smiled bitterly in his heart, and thought of asking the old professor.

"The first method is leaf insecticide! This method is simple and easy, that is, 1 kg of fresh neem leaves or stinky leaves are mashed, soaked in the same amount of water for one day, filtered and slag removed, and 50 kg of water is added to spray, which can prevent and control cabbage insects, aphids, etc.; The second method is to kill insects with vegetables, 50 grams of green onions, garlic and chili peppers, wet and mashed, wrapped in gauze, soaked in 15 kg of water for 24 hours, sprayed with leaching solution, which can effectively control aphids and red spiders...... The fifth is the 'sugar-coated cannonball' method......"

"Oh? Sugar-coated cannonballs? Tang Shenyuan was also surprised to hear this idiom, and couldn't help laughing.

Professor Wu continued: "Use 'sugar-coated cannonballs' to trap and kill insects. Take 0.5 kg of brown sugar, 1 kg of vinegar, add 10 kg of water, mix and stir, then add an appropriate amount of insecticide, and place it in the vegetable field.......

"Huh? Still using pesticides? Tang Shenyuan said: "This can't work, no, you can't use pesticides!" ”

"Its practical insecticide in small quantities will not be dangerous hài ......"

"Forget it, what we want is absolutely natural and pollution-free green vegetables, and pesticides must not be used, otherwise it will affect the ...... of reputation" Tang Shenyuan said very resolutely, this is what he must insist on, or he will do it since he has done it, he will do the best!

"Well, you're right!" Professor Wu pondered for a moment and said.

He agreed with Tang Shenyuan's words, although he knew that it was okay to use pesticides appropriately, but if it was easy to become dependent after using it once, there would be a second and third ...... In the future, the vegetables in Honghe Village will not be green vegetables!

He said, "In that case, there are only two options left......

"Aren't there three other ways?" Tang Shenyuan was sure that he was not mistaken, so he said this.

"There are two ways, the first is to kill insects with fresh neem leaves or stinky leaves and the second is to kill insects with vegetables!"

"The third method, can't you use baking soda liquid? Isn't that leaf supposed to be poisonous? ”

In Tang's far-reaching impression, baking soda is not poisonous, who hasn't drunk soda? Why can't it be used?

Over there, Professor Wu smiled when he heard Tang Shenyuan's words, "Baking soda is very edible and industrial, of course it is not toxic when eaten, but baking soda for industry is low-toxic." And although the neem leaves are poisonous, they are natural toxins and not strong, they will decompose quickly, and they will not be dangerous to the human body, and the neem tree can also be used in medicine! ”

"Hehe, since the professor said that you should use these two methods, then use these two methods!" Tang Shenyuan doesn't know much about this kind of thing, Professor Wu is a professional, and his opinion is the most important. "Then I'll go prepare something to kill insects now......"

"Wait, are you ready for what I told you earlier?"

"What? What's the matter? Tang Shenyuan was puzzled.

Wu Shengming over there suddenly smiled bitterly and said, "It seems that you have forgotten, okay, it's the matter of cultivating grain seeds!" ”

"Oh, that's it, I've already started to prepare......" Tang Shenyuan said nonsense with his eyes open.

He can't let the old professor think that he is not doing his job properly, otherwise he will definitely teach himself a lesson when he comes to Honghe Village in the future!

"Well, this matter must be grasped quickly, it is November now, it is best to take care of everything now, and when the spring comes, you can sow seeds and start cultivating."

"Okay, I've got it!" Tang Shenyuan felt bitter for a while, why was he so busy?

……

"Brother Asheng, will this work?"

Oolong looked at Tang Guangan carrying a sprayer on his back spraying vegetables with water mixed with onions, garlic and chili peppers, although he wanted to vomit when he smelled the smell, but he didn't have a score in his heart about the insects, after all, who knows if the insects have the concept of "smelly"?

"Yes, if you can kill insects with onions, garlic and chili peppers, won't people who buy pesticides lose money?" Oolong, his father said.

In his impression, except for the pesticides produced by science and technology, which are more effective for insects, other soil methods do not work, and even if they are a little useful, they cannot completely kill the insects, and they are in vain.

Tang's father and Tang's mother didn't have so many worries, because they knew that this method was taught by Professor Wu Shengming, and it should work, but they were teachers in the university, so they knew a lot, could the method he gave not work?

"If you want me to say that it's better to soak the water in neem leaves first......," said Uncle Tang Qinghe.

Tang Shenyuan nodded and said: "I want to fight both, neem leaves and water can kill insects, onions, garlic and pepper water can control insects, and only two prongs will work, even the leaders have said 'both hands must be caught'!" ”

Tang Qinghua is also there, he is very concerned about this insect plague, because he knows that the success of this greenhouse vegetable project means that he can ensure his leadership of Honghe Village, this project was proposed by Tang Shenyuan, he supports Tang Shenyuan, and if Tang Shenyuan fails, it also means that he also fails.

Because Tang Shenyuan's success and the pie he painted made the people of Honghe Village full of longing for the future, they were willing to follow them, and even the people on the village chief's side put aside their prejudices and accepted their command. If the project fails, not only the people on the village chief's side will blame them, but even the people on their own side will blame them, and they will definitely fall to the Tang Navy's side at that time.

……

"What are they doing?"

"What are you spraying with a plastic bag on your back?"

"Damn, I don't even know the sprayer, and the plastic bag hahaha, you're so funny!"

"Sprayers? Are they spraying pesticides? ”

The tourists reacted and were angry.

"Didn't you say good green vegetables, why do you still spray pesticides?"

"Hey, are there still fewer people in society who say one thing and do another?"

"So we've been fooled, dozens of dollars a pound of vegetables, can such vegetables be worth fifty yuan? I can sell more than a dozen catties for fifty yuan in the vegetable market......"

"Let's go, go over and ask Tang Shenyuan for a clear ......"

Tourists come here because they have heard that Honghe Village has beautiful scenery and delicious food, and many tourists have tried green vegetables these days and found that they are indeed delicious, much more delicious than ordinary vegetables. After eating, I don't want to eat other vegetables, and many people will buy a few catties to take back before leaving, just to let their families eat delicious vegetables, but now...... It was found that they were actually spraying pesticides on vegetables, which made tourists feel cheated.

Fortunately, Tang Shenyuan, "Brother Tang", has a good reputation on the Internet, so although the tourists were angry, they did not smash it directly, but chose to go to him to ask him for an explanation!

"Hey, a lot of people are coming over there, who are they?" Oolong was the first to spot the tourists.

Tang Shenyuan They were said by Oolong, and they also found a group of angry tourists, Tang Shenyuan hurriedly came over to receive the tourists, he went out for more than half a month, and now these tourists are basically unfamiliar faces.

"Hello everyone, it's so late to come out to play!"

It's sunset, and most people go home to cook, but it's the best time for tourists to play, isn't there a poem that says? "The sunset is infinitely good, but it is just near dusk". How timidly it is to go out for a walk at dusk, especially in the beautiful part of Red River Village.

But as soon as Tang Shenyuan's words came out, some anxious tourists rushed to say:

"If it hadn't come out now, I wouldn't have known that you would have applied pesticides to vegetables......

"Yes, it is! Don't think that if you want to take advantage of the lack of people at dusk, no one will see the pesticides on the vegetables......"

"You are deceiving us by coming to you so enthusiastically, and the vegetables we eat are still made of pesticides...... The price is still so high! ”

"Liar!" "Unscrupulous merchants!" “……”

Hearing the words of the tourists, Tang Shenyuan was immediately stunned, while the other villagers were panicked, they knew that this was not spraying pesticides, but they didn't know what to do in the face of a group of angry tourists. These tourists are the gods of wealth who have brought wealth to Honghe Village, so you can't offend them!

"Hahaha......"

At this time, Tang Shenyuan smiled, and the smile was very surprising, and the tourists were stunned.

Or the tourist just said, "What are you laughing at? Did we sting you in the sore spot and become angry? Don't think we're afraid of you, believe it or not, we're exposing you online! ”

As soon as these words came out, the eyes of other tourists suddenly lit up, and they all responded with words:

"Yes, this kind of person should expose them, otherwise more people will be deceived!"

"Ordinary vegetables are sold as green vegetables, this is price deception, and you can call the police......"

"I will never come to Honghe Village again, my classmates also said that they want to come here to play, and when I go back, I told him not to come again, because there is such a beautiful scenery here, but there is a group of people with black hearts......"

This is a bit of a curse, if Tang Shenyuan glanced at the villagers' eyes when they heard this, he knew that if he didn't open his mouth to explain the matter, it would become even bigger. Tang Shenyuan stopped Oolong and didn't let him talk back. Quarreling is a specialty of many rural people, who hasn't quarreled? Not to mention that a group of tourists don't know and talk nonsense, even if they take advantage of the reason, they will be scolded, and they don't know who their relatives are.

Tang Shenyuan stretched out his hand to suppress the riots of tourists and villagers, and said firmly: "We have no pesticides ......"

"You're blind, and the sprayer is still on your back, and you're talking nonsense with your eyes open......"

"Hehe, sometimes what you see with your own eyes may not be real......"

"Seeing is believing, hearing is false!" Said one tourist. "We've all seen it with our own eyes, do you still want to deny it?"

The tourists agreed with the tourist's words and said in agreement:

"That's right! Don't let them fool you......"
