AI Technical Summary

Technical Problem

The long-term and large-scale use of chemical pesticides to control tomato bacterial canker and bacterial wilt has led to environmental pollution and pesticide resistance problems. In addition, existing biological pesticides are not very effective and cannot meet the needs of green food production.

Method used

The fermentation liquid of Streptomyces venezuelae FK-11 was used in tomato cultivation by soaking seeds or drenching roots with the fermentation liquid to inhibit the occurrence of bacterial diseases in tomatoes, especially bacterial canker and bacterial wilt.

Benefits of technology

It effectively inhibits disease occurrence, increases tomato yield, is easy to operate, non-toxic, environmentally friendly, reduces the use of chemical pesticides, and meets the requirements of green food production.
