On September 16, an expert group conducted a field test of the cooperative project “Chinese chive IPM and green control technology demonstration and service” between HAAFS and Hengshui City, which was undertaken by researcher SONG Jian from Institute of Plant Protection. The demonstration base is located in Wuluo County and the area of the core demonstration base is 1000 mu.

Researcher SONG Jian briefly introduced the key points of the demonstration technology. The technology takes biocontrol technology of applying 5 billion CFU/ml Bacillus thuringiensis suspending agent as the core, combines with black glue board(to monitor, trap and kill the pest), film mulching in fine weather(to kill the pest in soil by high temperature) and precise application of pesticide to carry out Chinese chive IPM.

The result of the field test showed that the seedling preservation rate was 81.8% and the control efficiency of Bradysia odoriphaga Yang et Zhang was 87.7% in the demonstration plot, while the corresponding data was 61.1% and 62.3% in the control plot. Compared with the control plot, the use of chemical pesticide decreased by 40% and the yield increased by 74.5% in the demonstration plot. Experts agreed that the IPM technology achieved excellent control efficiency and remarkable productive effect.
