1. Strategies and Approaches in Pest Control of Corn

2. Description and Taxonomy of Corn Description: Corn ( Zea mays ) is a major cereal grain native to the Americas. It's one of the most widely grown crops, used for food, animal feed, biofuels, and industrial products. Taxonomy: Kingdom: Plantae Phylum: Magnoliophyta Class: Liliopsida Order: Poales Family: Poaceae Genus: Zea Species: Zea mays

3. Corn Production and Uses Global Production: Corn is grown in various regions around the world, with the United States, China, Brazil, and Argentina among the top producers. Uses of Corn: Human consumption (cornmeal, corn syrup, etc.) Animal feed Industrial products (ethanol, plastics, etc.) Ornamental uses (cornstalks for decoration)

4. Major Insect Pests Common Insect Pests: Corn Earworm ( Helicoverpa zea ) Corn Rootworm ( Diabrotica spp. ) European Corn Borer ( Ostrinia nubilalis ) Fall Armyworm ( Spodoptera frugiperda ) Management Strategies: Bt corn (genetically modified to resist certain pests) Crop rotation Natural predators and parasitoids Insecticide applications (as needed)

5. Major Diseases Common Diseases: Gray Leaf Spot ( Cercospora zeae-maydis ) Northern Corn Leaf Blight ( Exserohilum turcicum ) Southern Rust ( Puccinia polysora ) Anthracnose ( Colletotrichum graminicola ) Management Strategies: Disease-resistant hybrids Crop rotation Proper field sanitation (removing infected plant debris) Fungicide applications (as necessary)

6. Major Weeds and Other Pests Common Weeds: Common Lambsquarters ( Chenopodium album ) Common Ragweed ( Ambrosia artemisiifolia ) Giant Foxtail ( Setaria faberi ) Other Pests: Birds (e.g., crows, blackbirds) Rodents (e.g., mice, rats) Management Strategies: Mechanical weed control (e.g., tillage, cultivation) Herbicide applications (pre- and post-emergence) Cover crops Scare devices and traps for birds and rodents

7. 01 02 IPM Principles: Integration of multiple management strategies Minimizing chemical use and environmental impact Emphasis on prevention and monitoring IPM Strategies: Cultural control (crop rotation, planting time, soil management) Biological control (beneficial insects, natural predators) Mechanical control (tillage, traps, physical barriers) Chemical control (targeted pesticide use) Integrated Pest Management (IPM) Plan
