In 2015, the Spring Festival in February just passed.

The Lingnan region has gradually entered spring plowing, especially in Qiongzhou with a tropical climate, where rice has been planted for a month.

The Academy of Sciences’ Agricultural Research Institute has a special tropical plant research institute in Qiongzhou.

Mr. Yuan, wearing a straw hat and dressed as an old farmer, was checking the earing of rice on a large experimental field.

However, looking at the situation of this large rice field, he frowned and turned his head: "Xiao Wang, the rice transplantation in Qiongzhou is January 15th and 20th!"

Assistant Xiao Wang nodded: "It's this time."

Several other researchers also found something was wrong. According to general circumstances, the heading stage will begin to begin about one month after rice transplanting.

The rice in Qiongzhou was planted on January 15 and the 20th. It is now February 29th, but the heading period is not even entered on this large rice field.

"Will it be the impact of the weather this year?" said one of the researchers.

Mr. Yuan shook his head: "Even if the weather is lower than last year, it will not have much impact on Qiongzhou. There must be some other reasons."

Then everyone took samples of the experimental field and took it to the research institute for testing and analysis.

While paying attention to the laboratory analysis, Mr. Yuan ordered the staff to pay attention to the situation in various parts of Qiongzhou.

Laboratory of Qiongzhou Agricultural Research Institute.

Researchers are conducting comprehensive assay analysis on hundreds of samples.

Hu Guangyi discovered through high-precision microscope that the straw tissue of rice was attached to some fungal communities.

The fungal community shows that the conidia stems are not branched, with 35 clusters of roots, protruding from the host epidermis or stomata, with a size of 8016046μm, with 28 diaphragms, slightly enlarged at the base, light brown, upward color, curved at the top, and above conidia.

Conidia are colorless, pear-shaped or stick-shaped, often with 13 diaphragms, 1440614μm in size, and have foot cells at the base.

Judging from the morphology, it should be the typical pyriculariaoryzaecav..

Pears spores can cause rice blast, also known as rice fever, commonly known as fire plague, head plague, neck plague, etc. It is an important rice disease worldwide. Rice blast is the most widely and most common rice fungal disease in the world.

Under natural conditions, blast bacteria only infects rice, which is an epidemic that is transmitted through airflow.

Hu Guangyi thought strangely, logic is that the new varieties in Qiongzhou experimental fields have good disease resistance. In addition, the use of preventive pesticides, how could so many colonies be found in straw tissues?

"Li Can, what is the level of Pear Sporidium in your sample?"

"Broadly speaking, do you have a lot of pear spores in your sample?" Li Can turned his head and asked back.

Hu Guangyi nodded and replied: "The 12 samples in my group are very serious. According to the prevention and control standards of our experimental fields, it is impossible to have such a serious saphenous outbreak."

Then the test analysis results of the other eight groups also came out. Hu Guangyi and Li Can frowned immediately with the test sheet.

Their experimental field tested a total of four new varieties this year, but none of these four varieties were spared and were infected with dense cloves of pear spores.

"Li Can, you bring people to conduct in-depth research on these pear spores, and I will report to Director Yuan."

"good."

Looking at Hu Guangyi's hurried back, Li Can quickly turned around and ordered: "Prepare for genetic testing."

He suspected that there were mutated varieties of Pear Sporidium, and the rapid genetic testing was carried out non-stop. Looking at the test sheet results, Li Can's heart sank.

Pearl spores can be divided into 7 groups and 128 physiological species. However, the results shown in the test sheet are not one of the 7 groups and 128 physiological species.

That is, this is a mutated variety.

"Try the compound fungicide with Gerbis and rice."

"OK."

Half an hour later, the effect of Rebis and rice-added rice was not obvious. You should know that this compound fungicide was generally more than 95% for the previous raspberry spores, and is currently the first choice for the prevention and treatment of rice blast.

Li Can's heart became deeper and he quickly ordered: "Try other fungicides."

“Preparing.”

The effect of propionazole solution is not obvious.

The compound fungicide of mutant and sulfur obtained a killing effect of about 4,060. However, after the second generation of mutant pear spores, the killing effect began to become less obvious.

The composite fungicide of tricyclazole and sulfur also has a certain killing effect on the first generation, but the effect plummeted from the second generation.

Even if several fungicides are used alternately, the mutant Pearsporidium will develop drug resistance after three or four generations.

Mr. Yuan, who had just arrived, looked at the test reports and Li Can's disinfection experiments and knew the seriousness of the matter.

He had contacted agricultural technology stations in various parts of Qiongzhou. The problem was not just the experimental fields of the institute, but this situation was generally seen in Qiongzhou.

"Broadly speaking, Li Can."

"director."

"You will test all the fungicides on the market to see if there is any fungicide that can inhibit the outbreak of rice blast." Mr. Yuan ordered seriously.

"no problem."

Mr. Yuan came to his office, opened the login program of Nanke Dream World, and quickly put on his brainwave glasses.

Nanke Dream World Truth City.

Inside the Agricultural Research Institute.

He immediately summoned everyone from the Agricultural Research Institute and reported the matter to Huang Mingzhe.

...

At this time, Huang Mingzhe, who was at the Phoenix Project Research Base, immediately received a reminder from the ghost.

After taking out his phone, he found that it was Mr. Yuan’s expedited report. After browsing it at a glance, Huang Mingzhe had already guessed the reason in his mind.

He immediately found an office, logged directly into Nanke Dream World through his brainwave glasses, and came to the Agricultural Research Institute of Truth City.

At this time, there were already crowds of people in the Agricultural Research Institute, and it was obvious that everyone realized the seriousness of the matter.

You should know that rice accounts for a very important proportion of China's grain. The annual grain production in China is about 610 million tons, while the annual rice production is about 200 million tons, which reaches 30%.

In addition, the current domestic grain self-sufficiency rate is between 8,085. Once rice is completely out of stock, the domestic grain self-sufficiency rate will drop to between 5,060.

Even if there is reserved grain, this gap is very terrible.

While listening to discussions by agricultural experts, Huang Mingzhe asked the ghost to investigate the rice situation across the country. Rice in the north and northeast has not been planted yet, and the main focus is on Lingnan and southwest.

Sure enough, after investigation, rice blast situations occurred in various places.

Suddenly he turned his attention to Southeast Asia and India, and asked the ghost to investigate the situation in these areas.

As tropical areas, rice cultivation in these areas is earlier than most areas in China, similar to Qiongzhou. If these areas are also infected with rice blast, they are probably entering the stage of a major outbreak.

Sure enough, as the messages were dug out by ghosts, the rice in Southeast Asia and India suffered from very serious rice blast disease.

Huang Mingzhe informed the situation to Mr. Yuan and other experts, and they frowned. The scale of the infection was really terrifying.

Once food exporters such as Southeast Asia and India are seriously affected, coupled with the current international food prices, there will be problems in Asia, and it will be very serious.
