Case Study: Controlling Corn Borers in Xinjiang Province

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.

 

Operation Time	25/6/2017-13/7/2017	Location	Bole City, Xinjiang Province, China
Terrain	Dry lands	Environment & Weather	Sunny (16°-26°C) Level 2 winds

 

 

Dosage

 

The team decided to use multiple pesticides to achieve optimal results. Detailed information is as follows:

 

Pesticide	Dosage Form	Effective Component and Concentration	Dosage (per acre)
Beta-cyfluthrin	Suspending agent	10%	40.24 ml
Chlorpyrifos	Emulsifiable Concentrate (EC)	45%	610 g
Profenofos & Phoxim	EC	Total: 40 Phoxim: 34% Profenofos: 6%	121 ml

 

 

Operation Parameters

 

Operation Mode	Intelligent Operation Mode	Flight Speed	4.5-5 m/s
Flight Altitude	2.5 m	Working Interval	5 m
Dosage (liters per acre)	1	Nozzle Type	Fan shape XR11001

 

 

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.
