| Abstract: | Applying pesticide for disease, insect and weed control during maize cultivation is an essential work in each crop growth season in the Hexi Corridor Region(HCR) in Gansu province. Pest infestation, status of pesticides application in maize field of this region has not been clear yet. These were investigated and summarized in the year of 2017-2019. The results indicated that Corn Stalk Rot(Pythium spp. & Fusarium spp.), common rust(Puccinia sorghi) and ear rot(F. verticillioides & F. graminearum) are the dominant diseases. Aphids(Rhopalosiphum maidis) and spider mite(Tetranychu cinnabarinus & T. trtuncantus & T. urticae) are the dominant insects. Green bristlegrass(Setaria viridis), barnyardgrass(Echinochloa crus-galli), lambsquarters(Chenopodium album) and redroot amaranth(Amaranthus retroflexus) are the dominant weed species. Total pesticides active ingredients applied in this place is at 33. The phenomenon of increasing the frequency and the number of pesticides input per application blindly, even the use of unregistered pesticides is prevalent. |
