A Jilin Province corn field in September 2012 where army worms
stripped lower leaves off the stalks. The corn cobs are left intact.
The battle against bugs like army worms in China usually includes swarms of farmers sent out to drench fields with pesticides. The collateral damage that results is implied by the emergency notice which exhorted local officials to "scientifically" use effective, low-toxicity pesticides and to use a "green" mentality in pest control. Apparently, many farmers were poisoned pesticides during the previous year's army worm control campaign. The 2013 emergency notice warns readers to "learn a lesson from last year's farmer poisonings and heat stroke in many areas."
