The invention discloses a compound
microbial agent for preventing and treating muskmelon
fusarium wilt and application of the compound
microbial agent, and belongs to the field of biological prevention and treatment. The microbial inoculum is composed of
pseudomonas aeruginosa and
bacillus subtilis, the
dosage form is a liquid microbial inoculum, and the effective
viable count is greater than 10 billion / ml. The two strains are high in sporulation quantity and strong in
rhizosphere colonization capacity, have synergistic bacteriostasis and
growth promotion effects, effectively inhibit
fusarium oxysporum of muskmelons through a plurality of mechanisms such as competition,
secondary metabolite generation and
system resistance induction, and have a remarkable inhibition effect on
fusarium oxysporum of cucumbers, watermelons and tomatoes, soil-borne
pathogenic bacteria such as
phytophthora capsici and the like. The
microbial agent is broad-spectrum, efficient and long in lasting period, and can promote propagation of
rhizosphere effective microbial communities, reduce the dosage of chemical pesticides, relieve
continuous cropping obstacles and promote green and high-quality development of the watermelon and melon industry.
