Walking into a cesspit, the best evil widow wants to stand up

In addition, Shen Ping also discovered that for some unknown reason, the insect pest problem of traditional rice varieties was not as serious as that of high-yield rice varieties.

However, Shen Ping quickly found the reason, because these are native plants that have adapted to the local environment and climate and have strong disease resistance.

However, the high-yield rice that we brought out had not yet adapted to the environment and had a relatively weak ability to resist insect pests. It was like flowers in a greenhouse that were brought outdoors and could not withstand the wind and rain.

This requires an adaptation process. After planting this season and saving the second generation of seeds, the next season will be much better.

Shen Ping had just returned home and had not had time to catch her breath when Dadong came back from the fields. At the same time, he brought bad news: the rice at home was also diseased.

Dadong said worriedly, "Madam, the rice seedlings were fine yesterday, but when I went there today, I saw something was wrong. The leaves were a little yellow. I pulled up the plants and saw that there were tiny planthoppers all underneath, densely packed."

Shen Ping knew that what Dadong said was right, because she had also gone to see it two days ago and had observed carefully that the rice was growing well.

I didn't expect that the rice would change every day. If it is allowed to spread like this, even if there is no guarantee of a total harvest, the yield will definitely be severely reduced.

This field is connected to the rice fields in Dahe Village. There are signs of planthoppers now, but it does not seem serious at the moment.

Hearing Dadong say this, Shen Ping realized the importance of the situation.

One characteristic of this rice planthopper is that it reproduces quickly and can become a grandmother in three days.

The rice fields adjacent to Niugu Village and Dahe Village will definitely be affected by the disease the first. We can’t delay any longer and we must quickly formulate a pest control plan.

The weather is clear and there is no rain now, which is the best time to spray pesticides. However, the fastest time to spray pesticides is after the afternoon.

In the south, the weather in June is already very hot. Now that the sun has risen, the temperature has risen. If pesticides are sprayed at too high a temperature, the pesticide concentration will be high and the plants will be in danger of burns.

If the concentration is low and cannot achieve the insecticide effect, the best time to spray is between 9 and 10 in the morning and after 5 in the afternoon.

And most importantly, Shen Ping has not prepared the pesticides yet. In addition, she also needs tools for spraying insects, so the fastest time would be the afternoon.

"Madam, something bad has happened~" Tietou ran in like a flash.

Shen Ping frowned, and Hong Gu scolded: "Big Head, what are you in such a hurry about? Just talk about it."

Tietou took a breath and said anxiously, "Madam, this pepper tree has started to have bugs. They are tiny bugs crawling on the trunk and behind the leaves of the pepper tree. They are so densely packed that it's scary to look at.

Some leaves are curled up, I caught some and brought them back, madam, please have a look." Tietou wrapped some insects in leaves and handed them over.

"Madam, please let me see it!" Hong Gu stretched out her hand and was about to take the thing that Tietou handed over.

Shen Ping spread out her palms and said to Tietou, "It's okay, give it to me."

Tietou carefully handed a leaf to Shen Ping. Shen Ping opened the leaf and saw that this pest was familiar to her: it was called aphid.

These aphids specialize in sucking sap from crops. If these things grow on crops, the leaves will curl up or even fall off in just a few days. The harm they cause is no less than that of planthoppers.

Shen Ping handed the insect to Hong Gu and said, "Okay, I bought some medicine on a foreign merchant ship. I'll give it to you later. Don't disturb me."

Back in the room, Shen Ping went to the mall, opened the search bar, typed in pesticides, and immediately a variety of pesticides appeared.

Shen Ping carefully observed the introduction of these things and picked out a few. She knew that both of them could be treated with the same pesticide, cypermethrin.

In her previous life, she had grown flowers and had encountered insects. She went to an agricultural science store to ask, and someone introduced this to her. This product is more toxic.

There is also another one called imidacloprid, but it is a powder and its effect may not be as good as the previous one.

There is also a drug called thiamethoxam, which also has a good control effect on rice planthoppers.

However, the usage of these products is quite strict and they need to be diluted with water in a certain proportion. Shen Ping carefully read the instructions for use. She plans to conduct experiments in her own rice fields first.

After careful consideration, Shen Ping bought all three. He wanted to test them separately to see which one worked best.

We will start by fertilizing our own rice fields this evening, and then observe them tomorrow morning. If the results are good, we will distribute them in large quantities to neighboring villages.

In addition, Shen Ping bought the tools necessary for spraying insects and chose the most primitive pull-rod manual sprayer. Shen Ping selected it carefully.

Finally, she found a pull-rod sprayer that looked more original. It looked like bamboo in appearance, but was actually made of stainless steel.

"Great!"

Shen Ping jumped up excitedly and quickly bought one online. She tested it with water and found that the spraying effect was good and the range could reach six or seven meters.

This thing is really good, Shen Ping bought six or seven of them at once.

After the afternoon, Shen Ping asked Dadong to bring the young and strong servants in the family to put the pesticides in a dung bucket and carry it to the field.

She also went with him. She would feel uneasy if she didn't go, and she had to give a statement.

For safety reasons, Shen Ping prepared cotton masks for everyone and told them to wear them. She also took the lead in demonstrating and explained to them carefully.

In addition, Shen Ping also specifically instructed them to try not to let their hands come into contact with pesticides to avoid skin absorption.

For each type of pesticide, Shen Ping carefully explained to them how much pesticide to add and how much water to mix, and everyone divided the work and cooperated. Each person used a fixed amount of pesticide and was responsible for an area.

Many people were also curious. It was the first time they saw such insect killing, and no one dared to get close. They had also heard about the insect pests in Dahe Village and Niugu Village.

They were fully aware of the seriousness of the matter and knew that Dachunniang was conducting an experiment, so no one dared to disturb her. They just discussed in a low voice and watched from afar on the village road.

Shen Ping ignored them and told Dadong to arrange for someone to spray pesticides and someone to fetch water. Shen Ping marked each rice field.

It is made of a wooden board, on which is clearly written what kind of pesticide to use for this field and how to add water in proportion.

Shen Ping observed carefully and found that these rice fields had a tendency to spread, and this trend had to be suppressed as soon as possible.

In addition, the peppers have just become sick, so the impact is not great. The peppers are growing well, and the branches are full of peppers. They can be picked after a while.

The peppers didn’t get sick last season probably because the weather was cold. Now that the weather is hot, there are more pests.

In this way, nearly ten people worked until the sun went down, and finally sprayed all the rice fields and pepper fields that showed signs of disease.

The sun slowly sets, the sunset glow in the sky looks particularly gorgeous, and under the afterglow, the rice fields glow golden.

It is estimated that in half a month, the rice will turn into a real golden color and can be harvested at that time. Whether this medicine is successful or not will be known tomorrow morning.

"Come on, everyone is done, let's go back!" Shen Ping brushed off the mud on her trouser legs, looking a little tired. The setting sun stretched everyone's shadows out.

Everyone dragged their tired feet and followed Shen Ping.

Dadong admired Shen Ping very much at this time. "Madam, you have been promoted to the sixth rank and rewarded with a thousand taels of gold by the emperor. In fact, she could just leave these things to them."

She didn't have to do everything herself. But she didn't do that. Instead, she followed them to the fields. It was a blessing for their whole family to be able to follow such a master.

Besides, my lady knows everything, so this time the insect pest can definitely be eradicated. Thinking of this, Dadong's steps became lighter again.
