What if strawberries get anthrax? What is the prevention and control method of strawberry anthracnose?

What if strawberry is sick? Take strawberries directly to the doctor, free of charge! Miao renovated farm pioneered molecular detection technology for anthracnose, and farmers sent pieces free of charge. Take a look.

Once strawberry seedlings are infected with anthracnose, it is easy to die, and it is difficult to judge whether they are healthy or not by their appearance alone. Farmers often transplant to the field before a large-scale anthracnose infection occurs, resulting in heavy losses. A total of 25 million strawberries are needed in China every year, of which 20% are lost due to anthracnose. After the infected seedlings are planted, they will continue to get sick and die, and the rate of missing plants in strawberry fields can reach more than 30% in serious cases. Lu Hsiu-ying, director of the seedling transformation site, further explained that once anthrax broke out, seedlings must be constantly replenished, and through Rain Water and irrigation, anthrax spread with the water, infecting the fruit and the entire park. Even because of the lack of seedling replenishment and missing the strawberry season, all kinds of costs have increased the burden on farmers.

It took three years to develop a molecular detection technique for anthrax-nested polymerase chain reaction primer pairs. Farmers only need to send samples of strawberry seedlings and obtain a genetic primer through molecular detection technology. you can tell if you're infected with anthrax. The testing time of the technology is only two days, and the farmers do not have to bear any cost, which is all absorbed by the seedlings.

Zhong Jianzhe, an associate researcher in the crop Environment course, who actually developed the technology, said that most farmers cultivate strawberry seedlings themselves in the field, leaving strawberry vines in December every year. As the mother plant, the mother plant can be magnified to 20-50 times according to whether it is healthy or not. It is hoped that in the first 50 mother plants, farmers will be able to test them all. Zhong explains that after unhealthy seedlings are planted, they will no longer be infected with anthracnose. Strawberries can easily be infected with anthracnose as long as they are hot and humid, but early-stage healthy seedlings can reduce the risk of infection.
