description: Corn rust. Corn rust is an important disease in South and Southwest China. It mainly infects leaves, ears, bracts and even male flowers in severe cases. In the early stage, only light yellow long to oval Brown pustular scars were scattered on both sides of the leaves, and then the bullae ruptured and the rust powder, i.e. summer spores, was scattered. In the later stage, black near-circular or Long-circular protuberances appeared on the lesions, and black-brown winter embroiders appeared after cracking. [Control methods]. [Planting disease-resistant varieties] The resistance of different maize varieties to rust is quite different, and using disease-resistant varieties is an effective way to control maize rust. [Scientific field management] timely sowing; appropriate reduction of nitrogen fertilizer, increased application of phosphorus and potassium fertilizer, timely spraying of foliar nutrients to improve disease resistance of maize plants; rational control of density, improve permeability. Early removal of plant debris in and around the field before planting, if found in the growing period should be timely pulled out and centralized destruction, maize harvest should also be timely removal of residual plants, stems and leaves, centralized burning or fertilization. Rotation and non-gramineous crop rotation can reduce the accumulation of pathogens. For sporadic maize, the diseased plants and residual disease bodies should be pulled out at any time. [Pharmaceutical control, prevention mainly] Spraying agents containing difenoconazole, tebuconazole, triazolone, propiconazole, pyrimethyl ester, ethermycin ester and pyrazole ether ester can effectively alleviate the occurrence of Southern rust in late stage of maize trumpet-silking. Prevention plan: in order to prevent the occurrence of Southern rust, farmers can use 25% powder, 20%, three zolone pesticide spray control. If there is no prevention in the early stage, spraying in the early stage of rust can also control the incidence of rust and reduce the impact on production to a certain extent.
