Control method for root-knot nematodes by adopting microbial agent

Abstract

The invention discloses a control method for root-knot nematodes by adopting a microbial agent, which comprises the following steps: 1, selecting seeds before sowing; 2, performing seed dressing before sowing; 3, performing soil preparation and bottom application; 4, sowing and raising seedlings; 5, transplanting and root dipping; step 6, performing drip irrigation for diseased plants. Various root-knot nematodes can be inhibited or directly killed, root-knot nematode disease harm is relieved, soil-borne diseases are effectively inhibited, continuous cropping obstacles are overcome, bacterial disease and fungal disease infection is relieved, the use amount of pesticides is greatly reduced, and the effects of improving product quality and improving commodity are achieved. According to the method, eggs of root-knot nematodes can be killed, and the method has extremely high phobotaxis and killing effects on larvas and adults. Compared with existing root-knot nematode control methods, the method has the advantages of being safe, free of pollution, long in lasting period, environmentally friendly and the like, can effectively control occurrence of root-knot nematode diseases, and is suitable for root-knot nematode control of various green pollution-free vegetables.

Description

technical field [0001] The invention relates to the technical field of prevention and control of root-knot nematodes, in particular to a method for controlling root-knot nematodes by using microbial agents. Background technique [0002] Root-knot nematode is a highly specialized omnivorous phytopathogenic nematode. Root-knot nematode mainly harms the roots of various plants. It shows that the lateral roots and fibrous roots increase more than normal, and form a spherical or conical shape on the fibrous roots of young roots. Varying white root nodules, some of which are bead-shaped, the above-ground growth of the affected plants is short, slow, and the leaf color is abnormal, resulting in few fruits, low yield, and even causing early death of the plants. The control measures for root-knot nematode disease mainly include chemical control , Microbial control and electric control method, the general control method will cause some pollution to the soil, and the effect of control ...
