"Plant vaccine" 10,000 acres of wheat field in Maogang Village, Huangji Town, Xiangzhou District, Xiangyang City
Turning "Enemies" into "Friends"
"Pathogenic fungi are the 'enemy', fungal viruses are the 'enemy' of the 'enemy', and the 'enemy' of the 'enemy' is not our 'friend'?"
On May 9, the on-site observation and research exchange activity of "Green Technology of Plant Vaccine to Promote Wheat Disease Resistance, Quality Improvement and Yield Increase" was held in Xiangyang. Professor Jiang Daohong of Huazhong Agricultural University has once again attracted attention from all walks of life for his "brain-opening" green crop disease prevention and control achievements - "plant vaccine".
In short, the result is to use plant pathogenic fungi that carry fungal viruses as "medicine", improve the comprehensive disease resistance of plants, and "treat the enemy of the enemy as a friend".
"It is not a way to treat insects and diseases, but a new way and technology to use beneficial microorganisms to fight diseases." Jiang Daohong said that the "life" and "body" of crops can be infected by a variety of pathogens, and studies have found that more than 80% of crop diseases are caused by pathogenic fungi. The team used the non-pathogenic and endophytic characteristics of the pathogenic fungi carrying the fungal virus to inject the seeds or plants with a "vaccine" to stimulate the plant's disease resistance, and skillfully used the SsHADV-1 fungal virus to induce the "enemy" of the "other camp" to become a "friend" to achieve the purpose of protecting the plant.

It is understood that Professor Jiang Daohong and his team have been committed to the research of plant disease resistance for 14 years. In 2010, they successfully isolated the disease-resistant DT-8 strain from the rapeseed strain of Datong Lake in Yiyang, Hunan. Starting from this, the disease resistance blessing of "plant vaccine" has been realized on crops such as rice, rapeseed, barley and corn.
Following the successful development of "plant vaccines" for rice and rape, the team has been trying to develop a "plant vaccine" for wheat since 2023. Wheat is considered to be a non-host plant for Sclerotinia sclerotiorum, and the team found that Sclerotinia sclerotinia is a friend of cereals, and Sclerotinia can be detected on wheat and wild oats, and Sclerotinia can grow endophytes on wheat without harming wheat. Taking advantage of this characteristic, the team developed a vaccine called "Green Maibao", which uses the fungal virus SsHADV-1 to "suppress" S. sclerotinia to make it lose its pathogenic ability, and at the same time, endophytic Sclerotinia can "help" the crop's immune system and improve the comprehensive disease resistance of crops.
According to statistics, the average annual loss of crop pests and diseases on the mainland is as high as 14 million tons. For a long time, the disease resistance of food crops has relied on chemical prevention and control such as pesticides, which has brought great harm to the environment. Finding a "good protection" program for "good seeds" has always been the direction that scientists are looking for, and the advent of the wheat plant vaccine "Green Maibao" has found a new way for the green prevention and control of wheat.
The results are already "visible to the naked eye"
The wind blows the wheat waves, and the harvest is in sight.
In the Agricultural Demonstration Park of Xiangzhou District, Xiangyang City and the 10,000-mu Contiguous Demonstration Area of Maogang Village, Huangji Town, more than 100 observation groups composed of academicians, professors, agronomists and researchers investigated the growth of "vaccine wheat" on the spot.
The reporter saw at the scene that in the wheat fields where the "plant vaccine" had been applied, the wheat seedlings were strong and the wheat ears were dense and neat. Wang Xizhao, a large planter in Maogang Village, Huangji Town, said: "At present, we use plant vaccine seed dressing, and its resistance is indeed relatively strong, and it can increase tillering and increase yield. ”
Wang Xizhao, director of the Agricultural Technology Extension Service Center of Huangji Town, also said that wheat seeds are mixed with "green wheat treasure", and the seedling condition is obviously better. Zheng Lu, a teacher from Huazhong Agricultural University, explained: "Seed dressing is to soak the seeds with 'plant vaccine', dry and sow seeds, which is equivalent to 'coating' the seeds, and the vaccine can accompany the plant for a lifetime after entering the seed to achieve long-lasting disease resistance." ”
Hubei Lushen Agricultural Technology Co., Ltd. this year demonstration planting vaccine wheat 1470 acres, general manager Bai Jianfeng said that at present, compared with the field without vaccine dressing, the incidence of scab is significantly lower, the wheat ears look fuller, and most of the leaves are still green, "Through field investigation, this year is expected to increase the yield by 50 catties per mu, and the income per mu will increase by 70 yuan, and the harvest is a foregone conclusion!" ”

According to Huang Chaoyan of Xiangyang Plant Protection Station, the "plant vaccine" has a good effect on wheat rust, scab, stem base rot, etc., and the results of multi-site field trials show that the wheat yield increase after treatment is 4.28% to 17.19%.
"Fast", "Qi", "Strong" and "Green", Bai Guiping, director of Xiangyang Plant Protection Station, commented on "vaccine wheat", she said, the apparent effect of plants at the seedling stage and adult stage has been "visible to the naked eye".
For the people, saving money, being effective, easy to operate, and increasing production and income are the keys to "light simplification" technology. It is worth mentioning that "Lumaibao" meets the requirements of "light and simplified" - use 300mL of "Lumaibao" mixed with water 3L to mix 25kg, and can be directly sown after mixing, which is convenient and practical, easy to learn and easy to learn.
More than that, "Green Maibao" also has no side effects on crop growth and development, pure biology, no risk, green and environmental protection, can promote the development of crop roots, strengthen photosynthesis, promote the efficiency of crop nutrients, can protect the health of crops throughout the process, realize the integration of sowing and disease prevention and control, and significantly improve production efficiency.
Towards a light simplification of the "fool technique".
At the results workshop in the afternoon, the scholars were full of confidence in the "plant vaccine".
"This achievement stands tall and innovative, and is a representative of new quality productivity!" Academician Kang Zhensheng said that under the general trend of green development, the proposal of "wheat vaccine" is innovative, providing new methods, new ideas and new paths for increasing and maintaining wheat production in mainland China.
In the 10,000 acres of wheat field, Academician Bai Lianyang carefully inspected the wheat seedlings and ears and said that he hoped that the "wheat vaccine" could be promoted to Hunan and other places for experimental trials and multiple site detection, so as to promote a wider range of testing and application research.
"The concept is new, the effect is good, the mode is good, the operation is easy, and the potential is great!" Academician Zhang Xianlong said that after the on-site observation, he was very confident in the results of the "wheat vaccine", and he hoped to strengthen basic research and applied research, so that the technology would become a more light and simple "fool technology", so that the people could use it well, and empower rural revitalization!
Signing ceremony for the cooperative development of plant vaccines
"Plant Vaccine to Promote Wheat Disease Resistance, Quality Improvement and Yield Increase Green Technology" Field Demonstration Observation Meeting
"The concept of plant vaccine mediated by fungal virus is original, the technology is green and effective, and the product is applied to wheat production in the field to resist disease and increase yield, providing new theories, new technologies and new products for the green prevention and control of crop diseases in the mainland, and the results have generally reached the international leading level." Scholars have come to this conclusion based on research.
With the advent of rape vaccine "Green Treasure", rice vaccine "Green Rice Treasure" and wheat vaccine "Green Wheat Treasure", a more optimistic prediction is that the broad-spectrum disease-resistant "vaccine" suitable for a variety of crops and multiple diseases will be more worth looking forward to. This will fundamentally improve the comprehensive immunity of crops and provide a green "shield" for solving food security and seed industry safety.
Integrate into the comprehensive chemical prevention and control system, open up the "last mile" of government, industry, academia and research, strengthen the research on the mechanism of increasing production and disease resistance, and forward-looking layout of industrialization and commercialization······ In terms of new things, "plant vaccines" have a bright future, but there is still a long way to go······
