NATESC: wheat pests & diseases to strike seriously at heading stage

From 9-10 April 2018, the National Agri-Tech Extension Service Center (NATESC) held a Business Conference on Occurrence Trend of Wheat Pests & Diseases at Mid and Late Stage in China in Xi’an City, Shaanxi Province. It is expected that in 2018, wheat pests & diseases will strike in a way severer than ordinary years at the mid and late stage. In total, 59.3 million ha area will be stricken nationwide, including 30.7 million ha by wheat diseases and 28.7 million ha by wheat pests.

 

“This season saw relatively late planting of wheat,” analyzed the NATESC, “Though the occurrence of wheat pests & diseases is lighter than previous years now, they may strike in an explosive way at mid and late stage when the pests & diseases ‘partner’ with the weather which will be hot and rainy.”
