Abstract

The present invention relates to Bacillus marinus-pyrimethanil compounded bactericide and applications thereof, particularly to a compounded bactericide containing Bacillus marinus and pyrimethanil, a pesticide and a plant disease prevention and control method, wherein a weight ratio of Bacillus marinus to pyrimethanil is 1:0.0005-500, and the compounded bactericide or pesticide can be especially used for preventing and controlling plant gray mold. According to the present invention, the action mechanisms of the two pesticides are different, and the two pesticides are compounded so as to provide the synergetic effect of the microorganism and the chemical agent, and achieve the purposes of advantage complementation, prevention effect improving, chemical agent consumption reducing, reduction of chemical agent residue in vegetables, fruits and flowers, and drug resistance incidence reducing.

Description

technical field [0001] The invention belongs to the field of prevention and control of plant diseases and insect pests, in particular to a compound fungicide and its application, especially a fungicide compounded with marine bacillus and pyrimethanil and its use in preventing and treating botrytis cinerea application. Background technique [0002] Botrytis cinerea is a common and difficult to control fungal disease of plants (especially crops) in open fields and protected areas. It is a low-temperature and high-humidity disease. When the temperature is 20-25 ° C and the humidity is continuously above 90%, it is a period of high incidence of the disease. With the promotion of facility agriculture by the Chinese government, the high humidity environment of greenhouses has caused the gray mold of crops such as tomatoes and cucumbers and flowers such as gerbera and carnations to become more and more serious. At present, the main control method of Botrytis cinerea is chemical fu...
