Abstract

The invention discloses a biological control method for soft rot of amorphophallus. The method comprises the following specific steps: a xiandi special liquid medicine is firstly used for planting and cultivation; the xiandi special liquid medicine is allocated with water into xiandi special liquid medicine diluents with different concentrations, seed taros which are not sprouted are put in a first xiandi special liquid medicine diluents for soaking, a circle of xiandi special liquid medicine is sprinkled around a taro pond in the case of planting, a second xiandi special liquid medicine diluent is used for carrying out one to two times of sprinkling after seedling emergence, a third xiandi special liquid medicine diluent is used for one-time sprinkling during the middle growth period, a fourth xiandi special liquid medicine diluent is used for one-time sprinkling during the post growth period, infected plants in the early growth period are removed timely, the xiandi special liquid medicine is sprinkled in infected holes, and soil covering and firm stamping are then carried out. When the method of the invention is used for controlling the soft rot of amorphophallus, the soft rot of amorphophallus can be effectively controlled, features of the soil are not influenced after continuous three-year use, planting of the amorphophallus is not influenced, biological residues are few, and human health is not harmed.

Description

technical field [0001] The invention relates to the fields of plant protection and biological control of plant diseases, in particular to a method for biological control of konjac soft rot. Background technique [0002] Konjac soft rot is the most important disease of konjac. In recent years, with the continuous expansion of konjac planting area, soft rot frequently occurring in major production areas of the country has become an important factor restricting the development of konjac planting industry. According to statistics, in konjac soft rot disease-affected fields, the yield loss is generally 30%-50%, and in severe cases, it reaches more than 80%, or even no harvest. Konjac soft rot caused by Erwinia ( Erwinia spp.), which is a weakly parasitic soil-dwelling bacterium that is widely distributed in the soil and can invade from young tissues (roots, shoots, etc.) and wounds on konjac bulbs, among which wounds are the most important invasion way. After the invasion, the...
