Comprehensive care of the ground and underground to hold up the "protective umbrella" for the potato

From the home-cooked shredded potatoes on the dinner table to the tempting fries in fast food restaurants, it is inseparable from the yellow and heavy figure of potatoes. In recent years, under the background of the national promotion of the potato staple food strategy, China's potato industry has rapidly moved towards the development of large-scale, standardized and intensive farms, and the national planting area has reached 90 million mu. In Yulin City, Shaanxi Province, the potato planting area is 2.538 million mu, with a total output of 3 million tons of fresh potatoes, which has a significant effect on local economic development. However, along with the change of varieties, large-scale production leads to crop rotation stubble, seed potato transfer and other factors, resulting in the continuous invasion of potato aboveground leaf diseases and underground nematodes and other diseases and insect pests, which greatly affects the yield and quality of potatoes everywhere.

Recently, Bayer CropScience held the Bayer More Potato Technology Forum in Yulin City, Shaanxi Province, providing a high-quality platform for senior industry experts to "preach and teach", through knowledge lectures, solutions and field observation, etc., to bring an in-depth disease control and increase in income and quality sharing for the majority of potato growers, production and processing enterprises.

Professor Wu Xuehong of the Department of Plant Pathology of China Agricultural University introduced that potatoes have high value in ensuring food security and improving the health of residents, and the prevention and control of potato pests and diseases should focus on all aspects of the entire industrial chain, especially actively predict and forecast key diseases, so as to take precautions and timely prevention and control.

Leaf spot disease is the most important leaf disease on the Chinese potato, but it is not yet fully understood. At present, for common potato early blight, brown spot disease and leaf spot disease, the most important method is still the use of chemical fungicides for effective control. In the face of these diseases and pests of potatoes, the tailor-made Bayer More Potato Crops solution has emerged, like a "protective umbrella" for the whole process and comprehensive care of crop health. Ren Lu, Market Development Director of Bayer CropScience greater China, said at the meeting that for the aboveground disease sector, Bayer Lunatsen can effectively prevent and control early blight, regulate plant growth and promote crop health; Exploratory experiments have shown that Lunasen also has a prominent anti-effect on leaf spots and brown spot diseases; Bayer Silver Farley is effective in preventing and controlling late blight, achieving safety protection during the growing season and after harvesting. Albert Schirring, head of potato and vegetable strategy at Bayer CropScience, points out that on the one hand, ensuring an adequate supply of water and nutrients in the field can reduce the impact of poor potato conditions; On the other hand, it is advisable to use Lunasen when the disease is not seen during the flowering period to prevent and control diseases such as premature blight caused by a variety of pathogenic bacteria, and effectively achieve high yields.

In addition to the clear aboveground diseases, the control of underground disease plates is also a key link in potato plant protection. Taking the potato rotten stem nematodes that have developed rapidly in recent years as an example, Peng Deliang, a researcher at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, pointed out that exploratory experimental studies have found that in the prevention of decaying stem nematodes, Bayer nematode Lufuda seed mixing or soaking has obvious effects. Ren Lu also said that for the aboveground disease plate of potatoes, through Armas, it is possible to effectively prevent and control diseases such as black moles and scabs, and achieve early emergence of seedlings and strong seedlings; Combined with the microbial agent Zhuorun, it can achieve good effects such as developed root system, excellent growth, uniform potato formation, and increased yield.

During the outdoor field observation session, the delegates came to the potato pilot planting field in Yuyang District and examined the differences in pest control and pest control in bayer's more potato crop solutions and control schemes. Through comparison, it can be seen that the main stem branch of the potato using the Bayer scheme is thicker, the leaves are large and stretched, and the prevention effect of leaf spot disease is excellent, and the effect is obviously better than that of the control scheme in all aspects. Wang Lei, a large planter in Xiaoxulu Village, Balasu Town, Yuyang District, Yulin City, said: "Compared with the plots using Bayer's whole solution and the plots using ordinary schemes next to them, the potato yield increase effect is very obvious. Especially this year, there is a 100 acres of land, the signs of premature aging are very obvious, after using Zhuorun with nitrogen fertilizer, actually the land with premature aging was 'saved'. Zhuorun not only has a very good effect in promoting rooting and capillary roots, but also has the effect of preventing scabs. ”

Li Donghu, chairman of Inner Mongolia Grid Potato Seed Industry Group Co., Ltd., also introduced the "indissoluble relationship" between his company and Bayer CropScience. He said: "Our company has been actively introducing leading plant protection technology from international companies, and has been cooperating with Bayer CropScience for 19 years. Over the years, Bayer has not only provided us with quality solutions, but also continuously provided us with services such as technical exchange and training. From Bayer, we see the professionalism of focusing on crop diseases for decades, as well as excellent management philosophy. ”
