--FILE--A visitor is pictured at an exhibition hall of DJI (Dajiang Innovations) in Shenzhen city, south China's Guangdong province, 3 June 2017. Shenzhen-based drone maker DJI Innovation Technology signed a memorandum of understanding with Dow AgroSciences on Tuesday (27 June 2017) to work on the research and application of crop protection drones and technology. Dow AgroSciences, which is a wholly owned agricultural subsidiary of the United States' largest chemical company Dow Chemical, specializes in crop protection and seed products sold in more than 130 countries in the world. The two companies will conduct experiments to test the crop protection products carried and sprayed by drones. They will test and track the effect of drones spraying Dow AgroSciences' herbicide, insecticide, antiseptic products to come out with an optimized spray mode, pesticide formulation and dosage. The experiments will be first carried out in Heilongjiang, Jiangsu, Zhejiang, Anhui and Jiangxi provinces, starting the trial with rice.
