Background

Root-knot nematodes are highly specialized species of xenotrophic plant pathogenic nematodes. Root knot nematode disease must be prevented effectively by strictly implementing a plant protection policy of prevention-oriented and comprehensive control, emphasizing on grasping agricultural and physical control measures and matching with chemical and biological control.

The root-knot nematode has wide host range and can damage more than 130 crops in the 39 families. Nematodes are very small in size and difficult to see to the naked eye. The number of the pests in the soil is the most distributed in the soil of 0-20 cm, particularly in the soil of 3-9 cm. The male and female variant, female adult round pear shape, male adult threadlike shape, often leave the ovum or second instar larva in the soil or in the manure over winter or invade from the tender root when the environment is suitable next year, propagate harmfully. Nematodes can be transmitted through infested soil or seedlings and irrigation water. The nematodes quickly breed under the conditions that the soil temperature is 25-30 ℃ and the soil humidity is 40-70%, stop moving below 10 ℃ and die after 10 minutes at 55 ℃.

The existing insecticide is single in use and poor in insecticidal effect, and after the insecticide is used, root-knot nematodes are not thoroughly killed.
