Abstract

The invention discloses a method for controlling tobacco bacterial wilt through combination of Piriformospora indica with trichloroisocyanuric acid. The method comprises steps as follows: (1) sowing tobacco seeds in a seedling culture medium mixed with Piriformospora indica mycelia, and seedlings are transplanted to a field; (2) before transplantation, watering holes for tobacco seedling transplantation with a trichloroisocyanuric acid solution, and 10-15 days after transplantation, performing root-irrigation treatment with the trichloroisocyanuric acid solution. The used Piriformospora indica is not inhibited by the pesticide trichloroisocyanuric acid, can be combined with the trichloroisocyanuric acid for use and is applied to control on the tobacco bacterial wilt. The Piriformospora indica and the trichloroisocyanuric acid are combined for use to play a synergistic role in controlling the bacterial wilt, and the control effect is significantly superior to that of the single Piriformospora indica or the single trichloroisocyanuric acid.

Description

technical field

[0001] The invention relates to the field of plant disease prevention and control, in particular to a method for jointly preventing and treating tobacco bacterial wilt by utilizing Pyromorpha indica and trichloroisocyanuric acid. Background technique

[0002] Tobacco bacterial wilt is an important soil-borne bacterial disease on tobacco. At present, most of the prevention and control methods focus on chemical control. The use is also easy to cause bacteria to develop drug resistance, which brings difficulties to the continuous prevention and control of diseases.

[0003] In recent years, more and more people pay attention to the biological control of plant diseases. Biological control is to use beneficial microorganisms to produce various adverse effects on pathogenic bacteria (antibacterial, bacteriolytic, competition, hyperparasitic) so as to reduce the number of pathogens to weaken their pathogenic bacteria. At the same time, beneficial microorganisms use...
