Abstract: Baicheng City of Jilin Province has a long history of planting maize, which has made great contribution to China’s grain production. In order to verify the effect of plant protection integrated control scheme on disease, insect and grass damage in maize planting in field, Syngenta integrated control scheme was selected to compare with the conventional pesticide control scheme of farmers. The results showed that Syngenta integrated control scheme was superior to the conventional control scheme in strengthening seedlings, weeding and preventing diseases and pests. It not only had a very good control effect, but also significantly increased corn production.
