From May 5 to 13, technicians from a certain unit in Baodi District conducted a large-scale census of wheat fields in eight representative townships in the district, and conducted detailed investigations on key wheat pests and diseases. The result was a total of 14,8 wheat plants, representing an area of 5000,35 mu.

1. Occurrence of wheat aphid : the occurrence area is 45,100 mu, the aphid plant rate is 2780%, the average number of 4000 aphids is 3, the highest is 25, of which winged aphids account for 85.2% of the total aphid volume, and 2% of the aphid amount is concentrated in the panicle and inverted <> leaves. In the future, as the temperature rises and the reproduction rate accelerates, the aphid population will increase significantly.
2. Wheat powdery mildew and rust: In the entire census, no powdery mildew and rust strains and pathogenesis centers were found, but farmers should monitor the wheat field at any time.

       In view of the above situation, it is hoped that the vast number of farmers will seize the time to go to the wheat field to investigate and treat diseases and pests, and carry out prevention and control according to the situation.

       Pesticides and physical control are used together, and Tianjin Baodi District introduces our company's pest detection lights, meteorological monitoring stations and pest early warning systems to help monitoring personnel understand the dynamics of pests and diseases anytime and anywhere.
