New method for controlling rot knot nematode disease of protected vegetable

Abstract

The invention discloses a new method for controlling vegetable root knot nematode, which is characterized in that one or two from chitin, aropaz, Paecilomyces lilacinus and nematicidal pioneer is/are selected to process a seedbed in 1 to 2 weeks before the field planting of vegetables; 1.0Kg to 2.0Kg /mu (1 acre equals to 6.07 mu) of Fosthiazate and 20Kg to 60Kg/mu of harmonia mundi are mixed to process soil before the field planting; after the field planting, a biological agent is matched and used; the method is convenient to be used, is safe and effective, not only can effectively control the root knot nematode, but also can promote the growing of the vegetable plants, has the double effects of pesticide and fertilizer and can lighten the environment pollution brought by the use of the pesticide in large dosage; in the early period, the numbers of the eelworms in the soil are reduced by the mechanical eelworm pesticide of Fosthiazate; the stress resistance of the vegetables are increased by the chitin and the pesticide-fertilizer harmonia mundi; during the later period of the field planting, the numbers of the eelworms remained in the soil are controlled by using any of the biological agent of chitin, the aropaz, the Paecilomyces lilacinus and the nematicidal pioneer to irrigate the root, thus achieving the effect of controlling the vegetable root knot nematode by the cooperation of biology and chemistry and having very high popularization value.

Description

Technical field: [0001] The invention relates to a new method for preventing and controlling root-knot nematode diseases of facility vegetables. Background technique: [0002] Plant parasitic nematodes occur and cause damage in many countries and regions in the world, and there are various types. On a global scale, the occurrence and harm of plant parasitic nematodes are becoming more and more serious along with the development of agriculture and forestry and the changes of farming and cultivation systems. According to Esser statistics, until 1990, 207 genus and 4832 species of plant parasitic nematodes have been reported to be found in the whole world (Liu Weizhi, Duan Yuxi. 2000. Plant Pathogenic Nematodes. Beijing: China Agricultural Press, p1-2). Plant-parasitic nematodes are estimated to cause an annual loss of 12.3% of the world's major crops, exceeding US$ 100 billion, while actual losses far exceed estimates, citing the fact that damage caused by many nematodes is l...
