Abstract: The paper aims to figure out the effects of major diseases, insect pests and weeds of wheat on yield under current farming system. Anxin Plant Protection Station carried out an experiment on the natural loss rate caused by wheat diseases, insect pests and weeds from 2014 to 2016. Through the field experiment, we basically figured out that the loss rate of wheat yield was from 70% to 87% in the case of the natural occurrence of wheat diseases, insect pests (such as aphid) and weeds, and defined the contribution of scientific plant protection measures in wheat production. The experiment provides a reference for evaluating the damage and loss caused by wheat diseases, insect pests and weeds.
