At present, the control methods of root-knot nematodes by growers mainly include deep-cultivation of soil, exposure to sunlight, high-temperature shacks, crop rotation and use of nematicidal agents. However, these methods have certain limitations. Moreover, there are fewer types of chemical agents available on the market, and some have developed different levels of resistance. Then, how to effectively control nematodes is a concern of growers. The following are the experts who have interviewed the domestic online pest control and research, and learn how they control the nematodes. Biological control is the trend Root-knot nematodes have a wide range of hosts, strong reproductive capacity and adaptability, and are difficult to cure. Chemical control is still the main method to prevent such diseases. In addition, root knot nematode prevention and control can be carried out from various aspects. First of all, prevention work is crucial. At present, the following measures are mainly taken: (1) Quarantine to prevent root-knot nematodes from spreading with seedlings and preventing the introduction of diseases into disease-free areas; (2) Isolating diseased greenhouses and avoiding Diseased shed farm tools, seedlings, etc., to prevent disease spread between greenhouses; (3) drip irrigation watering, reduce root knot nematodes with water. Followed by agricultural control measures, grass crops or nematode-resistant vegetables that are not susceptible to infection by susceptible crops and root-knot nematodes, such as onions, garlic, and leeks, planting disease-resistant varieties, and timely and thoroughly removing diseased roots. Physical control is also an effective method, such as summer shack, steam disinfection, large flood irrigation during fallow, but physical control generally has a large cost and long cycle. Biological control. With the increasing awareness of environmental protection and food safety, biological control has received increasing attention. At present, the microbial killing agents mainly include Paecilomyces lilacinus, Verticillium grisea and some kinds of Bacillus. The biocontrol products are safe for crops and the environment, have no phytotoxicity and residue, but are easily affected by the soil environment. The stability of the control is poor. A variety of control methods can be combined in production. It has been reported that the use of P. sphaeroides and P. purpureus mixed preparations, Paecilomyces lilacinus and actinomycetes to achieve root-knot nematode have achieved good control effect. Our laboratory uses soil fumigation combined with biocontrol microorganisms to control vegetable root-knot nematodes. The results show that cotton-fumigation fumigation combined with P. sphaeroides has a significant synergistic effect, especially in the case of high nematode density. The yield of vegetables and vegetables was significantly higher than that of single cotton kraft fumigation or microbial treatment. Through the establishment of comprehensive prevention and control and soil health restoration system with biocontrol as the main body, the effective control of root-knot nematode disease in facility crops and the efficient use of biocontrol microorganisms can be realized. Restoring soil ecosystem stability is the core At present, the excessive use of chemical fertilizers and pesticides has caused soil deterioration and has become a necessity for root-knot nematodes. Soil deterioration leads to the basic failure of all killers (including biocides), and time-consuming, labor-intensive, and costly tillage soil replacement is the only measure. From this perspective, the current research and development, marketing and use of environmentally harmful killers are temporary “rule-free†strategies. They are digging their own graves. One day, future generations will pay for today’s small profits. Pay a painful price. It is gratifying that China has realized that the problem of soil degradation caused by excessive use of chemical fertilizers and pesticides seriously threatens the importance of agricultural production and national security of food. The goal of “one control, two reductions and three basics†also indicates the future. The main market for the prevention and control of root-knot nematode disease is not relying on certain single nematicidal products, but an effective comprehensive technical measure and supporting products. In summary, the core of Changzhi Jiu'an prevention and control root-knot nematode disease is how to “restore soil ecosystem stabilityâ€, which is the theoretical basis for the development of related products for nematode prevention and control.
