Abstract

The invention discloses a prevention and control method of corn diseases and insect pests. The prevention and control method comprises the following steps: step 1, clearing sick plants in the field, and burying seedlings scattered on the ground into the earth; step 2, air-drying corn seeds before the seeding, mixing the corn seeds and medicine, and mixing the seeds; step 3, when in seeding, covering the seeds with the soil comprising 50 percent of thiophanate-methyl powder and 50 percent of carbendazim wettable powder; step 4, when a corn plant grows for 20 to 30 days, spraying thiophanate-methyl; step 5, at the earing period of the corn, spraying mixed liquid of triadimefon, a dispersing agent and water; and step 6, spraying the plant by utilizing thiram wettable powder in 5 to 10 days before the earing of the corn. By adopting the method, the sphacelotheca reiliana is prevented in the whole process from the beginning of the planting to the maturity of the corn, so that the preventioneffect is better, and the phenomenon that the corn yield is decreased due to the improper prevention method can be avoided.

Description

technical field [0001] The invention relates to a method for preventing and controlling corn diseases and insect pests. Background technique [0002] Corn head smut, also known as black rice and dumb corn, commonly occurs in North China, Northeast China, Central China, Southwest China, South China and Northwest China. Since the disease was first reported in Northeast China in 1919, it has spread rapidly and occurred every year to varying degrees. From China's point of view, the northern spring corn region, the southwestern hilly corn region and the northwest corn region are more severely affected. In general, the annual incidence rate is 2% to 8%, and some plots reach 60% to 70%, causing heavy losses. In the 1980s, corn head smut was basically under control, but it is still one of the main diseases of corn production, seriously affecting the yield of corn. Contents of the invention [0003] In view of the above problems, the present invention provides a method for preve...
