The first registration of Bacillus velezensis as a nematicide in China

Date:02-26-2025

Recently, the 20 billion CFU/mL Bacillus velezensis MBI600 suspension product applied for by Nufarm was approved for registration in China. The registered crop and target pest are root-knot nematodes in cucumbers. This is also the first time that Bacillus velezensis has been registered as a nematicide in China.

Bacillus velezensis is one of the new types of microbial pesticide biocontrol bacteria. It is widely distributed in nature and can be isolated from marine environments, river sediments, soil, plant roots, plant tissues, and animal intestines. Due to its low toxicity, lack of pollution, broad antimicrobial spectrum, strong stress resistance, and ability to secrete various antimicrobial substances, it has great potential in the application of microbial pesticides. Bacillus velezensis can effectively control various plant fungal, bacterial, viral, and nematode diseases by producing antimicrobial substances, competing for nutrients, and inducing systemic resistance in plants.

Currently, there are four strains of Bacillus velezensis registered as pesticides in China. The other three strains (CGMCC No. 14384, C17271, M173) are used to control plant fungal diseases, including powdery mildew, red star disease, and black shank in tobacco, anthracnose in tea trees, powdery mildew in cucumbers, and Fusarium head blight in wheat, as well as bacterial wilt in tomatoes.

Dr. Luiz Antonio Alves Jose, Head of Staphyt Brasil, will attend the 6th Biopesticides, Biostimulants and Biofertilizers Summit (BioEx 2025) in Shanghai on March 13-14, 2025, and deliver a keynote speech titled "Biosolutions for Nematode Management: Insights from Brazilian Research and Global Applications". BioEx 2025 welcomes your participation!
