Pb1768 2010 Insect Control Recommendations For Field Crops –, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

An Integrated Pest Management (IPM) program integrates control tactics including cultural practices, variety selection, biological control and insecticides to manage insect pest populations so that economic damage and harmful environmental side effects are minimized. Insecticides should only be used on an as-needed basis; therefore, insect scouting must be conducted regularly throughout the season to determine if an insecticide application is warranted.

Pb1580 2010 Weed Control Manual For Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

This manual contains the 2010 University of Tennessee weed control recommendations for corn, grain sorghum, cotton, soybeans, burley and dark tobacco, wheat, forage crops, sunflowers and farm ponds. These recommendations are based on results of research and demonstrations conducted by the Agricultural Experiment Station and the Agricultural Extension Service. Decisions regarding recommendations are made by the University of Tennessee Weed Control Committee and are based on available data at various locations in the state.

This publication contains pesticide recommendations that are subject to change at any time. The recommendations in this publication are provided only as a guide. It is …

Pb1395-Insects In Farm-Stored Grain: 2009 Prevention And Control, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Insects damage stored grain in two ways:

1. Direct feeding damage, resulting in loss of weight, loss of nutrients, reduction in germination, reduction in grade and a lowering of market value.

2. Deterioration and contamination by their presence, resulting in downgrading of grain and lowering of market value because of foreign matter in grain (insects and insect parts), odors, molds and heat-damaged grain.

W076 Selecting Corn Hybrids For The Field, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Hybrid selection is one of the most important decisions a producer will make. Hybrid traits are introduced through breeding or genetic modification and there are many available options. Certain physical traits fit some field environments better than others or are better suited to specific end uses, such as silage vs. grain. The higher seed cost of specialty traits means growers must balance perceived benefits with the cost of using the newer technology. In addition to yield, producers should consider days to maturity, disease and insect resistance, and sometimes herbicide tolerance when selecting a hybrid to plant.

W077 Planting Corn For Grain In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Although seed genetics can dictate yield, a poorly planted seed never reaches its yield potential. Favorable weather plays an important role in stand quality, but producers can save money on replant costs by managing factors that can be controlled, such as field selection and planting time, seedbed preparation, seeding rate, planter settings and insect management.

W215 Organic Certification In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The USDA National Organic Program (NOP) defines organic agriculture as “a production system that is managed by integrating cultural, biological, and mechanical practices that foster cycling of resources, promote ecological balance and conserve biodiversity.” Organic production methods minimize the use of purchased off-farm inputs such as fertilizers and pesticides, while maximizing the use of on-farm practices that promote naturally occurring ecological relationships.
