Abstract

The invention relates to a method for preventing and curing root-knot nematode by utilizing benfuracarb and amino-oligosaccharin. The method disclosed by the invention comprises the following steps: before seeding crops or field planting, diluting 20% benfuracarb missible oil by 2000-4000 times, and spraying soil by using 30-60 L of diluted solution per mu; or, blending 2-5 kg of 5% benfuracarb granules into soil per mu, and then spraying; and, in the vegetative growth period, preparing pesticide a mixture with the weight ratio of benfuracarb to amino-oligosaccharin of 10:1 to 1:2, and uniformly spraying after adding water into the pesticide mixture with the use amount of 100-300 g of effective components per mu, wherein the spraying is carried out for one time every 30-45 days. According to the method disclosed by the invention, management is convenient; the root-knot nematode in the whole crop growth period can be thoroughly prevented and cured; the prevention efficiency is high; the investment cost per mu is low; the amino-oligosaccharin and the benfuracarb are used in a mixed manner; the synergistic effect is obvious.

Description

technical field [0001] The invention relates to the technical field of chemical control of root-knot nematodes, in particular to a method for controlling root-knot nematodes by using carbosulfan and amino oligosaccharins. Background technique [0002] Root-knot nematode disease is caused by several nematodes of the genus Meloidogyne, the main species are M.incognita, M.arenaria, and M. .hapla) and Javan root-knot nematode (M. javanica), the economic losses caused accounted for more than 90% of the losses caused by root-knot nematodes. [0003] Root-knot nematodes mainly harm underground rhizomes, and lateral roots and fibrous roots are the most vulnerable, often forming a large number of nodular root knots. The above-ground part has no obvious symptoms when the disease is mild, and when the disease is severe, it shows symptoms such as poor growth, short plants, yellow and smaller leaves, and weak flowering. [0004] Root-knot nematodes spread with diseased residues, insect...
