The invention relates to a pesticide, and especially relates to a complex bactericide composed of bacillus subtilis and a chemical bactericide. The bactericide is used for controlling brassica rapa pekinensis downy mildew. The bactericide comprises the chemical bactericide, bacillus subtilis XM16 CGMCC No.0372, and auxiliary materials. The bactericide is characterized in that the chemical bactericide in the active components is any one selected from metalaxyl, propamocarb, and mancozeb. A biocontrol bacterium is bacillus subtilis XM16, with the strain collection number of CGMCC No.0372. A weight ratio of metalaxyl to bacillus subtilis XM16 is 1-8:1-10. A weight ratio of propamocarb to bacillus subtilis XM16 is 1-10:15-140. A weight ratio of mancozeb to bacillus subtilis XM16 is 1-15:1-10. A form of the bactericide is usually hydrophilic powder or aqueous solution. The complex agent of the biocontrol bacterium and the chemical bactericide has a substantial synergetic effect in controlling brassica rapa pekinensis downy mildew. The biocontrol bacterium bacillus subtilis XM16 is advantaged in high bacteriostatic activity, high stress resistance, and wide bactericidal spectrum. The biocontrol bacterium is complexed with the oomycetes chemical bactericide, such that the pesticide dosage is reduced, and controlling effect is improved. The bactericide is an environment-friendly bactericide. The bactericide is advantaged in high biological safety, low cost, and substantial economic benefit.

The bactericidal composition provided by the invention has a significant synergistic effect, and can fully perform the controlling effects of 2-mercaptobenzothiazole zinc against bacterial, fungal and other diseases, and the good protective performance of 2-mercaptobenzothiazole zinc.

A disclosed compound sterilization composition containing oxathiapiprolin comprises an active component A and an active component B according to the weight ratio of 1:80-60:1, the active component A is oxathiapiprolin, and the active component B is selected from any one of the following compounds: metalaxyl, metalaxyl-m, propamocarb, propamocarb hydrochloride, cymoxanil and iprovalicarb. The composition has relatively high activity on multiple diseases of multiple crops, has obvious synergic effect, is expanded in bactericidal spectrum, and also has the characteristics of small drug usage amount, resistance to rain washing and obvious synergic effect.

The invention discloses an antibacterial culture medium for tissue culture of plants and a preparation method of the culture medium. A primary culture medium contains carboxylation chitosan, an antibiotic, hymexazol, urotropin, propamocarb hydrochloride, MS+6-BA(6-benzyladenine), naphthalene acetic acid, auxin and the like; a subculture propagation culture medium contains carboxylation chitosan, an antibiotic, hymexazol, urotropin, propamocarb hydrochloride, MS+6-BA, naphthalene acetic acid, chlormequat chloride and the like. Antibacterial agents are added to the primary culture medium and the subculture propagation culture medium, the pollution rate of the plants in the primary tissue culture and tissue subculture processes is reduced, the germination rate and the rooting rate of the plants during tissue culture are increased, and the economic benefits are improved.

The invention relates to a bactericide composition prepared by an auxiliary agent and a packing material carrier. The bactericide composition takes benthiavalicarb-isopropyl and propamocarb as the principal components and has special effects for preventing and controlling the downy mildew diseases of various crops, fruits and fruit trees. The composition has the advantages of simple production technique, no discharge of three wastes and convenient use.
