Tomato root knot nematode control
Sichuan readers asked: The root knot nematode of tomato has been seriously affected. How can we prevent it? Answer: Root-knot nematodes are eggs and larvae that overwinter in the soil with plant diseases, and can be transmitted by seeds, seedlings, soil, flowing water, and packaging materials over long distances. Loose soil, high dry terrain and low salinity are suitable for root-knot nematode activity. Chemical control: At the beginning of the disease, 1.8% avermectin 2000 times solution, 50% phoxim 1800 times solution, etc. are used for irrigation. 0.2-0.3 kilograms per strain of irrigating solution. In the growing season of vegetables, it is also possible to use a 1% sea-extinguishing 80-fold liquid surface spray control. If there are only sporadic diseased plants, the diseased plants will be removed in a timely manner, and the diseased plants will be destroyed or buried deeply to reduce the number of bases of nematodes in the park.
