Case Study: Controlling Corn Borers in Xinjiang Province

CornMG-1S

At the end of June 2017, Bole City, located in Xinjiang, China suffered an outbreak of corn borers. In order to control the outbreak, the Xi’an based Tianyi Aviation Technology Co., Ltd. sent out an agriculture service team that traveled 3,100 kilometers to conduct aerial spraying for affected cornfields covering 2,735 acres.

Upon arrival, the team assessed the situation and found that roughly 50-55% of the corn had been affected. Borers had severely damaged the young cobs and leaves of the corn, and the situation was deteriorating.

 

 

 

Spraying Condition

 

The weather was ideal for aerial spraying, with calm winds and mild temperatures. The team decided to start its operation on June 25.

Pest Control Effect

 

Random sampling before spraying showed that, on average, there were 30 borers per 50 plants. That figure dropped to 6 borers per 50 plants after spraying, meaning the borers' mortality rate was about 80%.

 

 

 

Result

 

The spraying proved to be highly effective in controlling pest infections.
