AgroPages-Armyworms break out in Shaanxi China, seriously endangering corn production-Agricultural news

By Think Real - Since the end of July 2016, the third-generation armyworms stroke corn planting regions in northern China. By 5 Aug., the national occurrence area of the pests reached 213,333.3 ha. Though the overall impact was less serious than that during 2012-2015, the pests broke out in Shaanxi Province, Henan Province and Shanxi Province due to improper field management, which lead to high pest volume in corn and rice fields with many weeds.

Specifically, the total occurrence area of armyworms in Shaanxi Province, Henan Province and Shanxi was 103,400.0 ha. The damage in the around 6,666.7 ha of corn fields in the intersection of the three provinces was serious and some of the corn leaves were eaten up. The occurrence area in Shaanxi Province was 40,200.0 ha, among which 733.3 ha was seriously stricken, the worst in recent years. In addition, those in Henan Province and Shanxi Province were 38,933.3 ha and 26,666.7 ha respectively.

Currently, the local government has initiated the emergency prevention and control pre-plan and started unified prevention and control. To shorten the time, modern plant protection machine like unmanned plant protection aerial vehicle flights and helicopters have become main tools. Aerial vehicle flights with brands from DJI-Innovations, Beijing TT Aviation Technology Co., Ltd., XAIRCRAFT, Shandong Wish Plant Protection Machinery Co., Ltd., Tianyi Aviation Technology Co., Ltd., Xi'an Aviation Base and Xi'an Xinnuo Plant Protection Service Co., Ltd. are working over the agricultural fields, spraying pesticides like DuPont Coragen® (chlorantraniliprole), lambda-cyhalothrin and emamectin benzoate.

In other corn planting regions, like Inner Mongolia, Hebei Province and Heilongjiang Province, there were also occurrences of third-generation armyworms, but the number of pests is small.
