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.

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.

Genetic Load And Transgenic Mitigating Genes In Transgenic Brassica Rapa (Field Mustard) × Brassica Napus (Oilseed Rape) Hybrid Populations, Christy W. Rose, Reginald J. Millwood, Hong S. Moon, Murali R, Rao, Matthew D. Halfhill, Paul L. Raymer, Suzanne I. Warwick, Hani Al-Ahmad, Jonathan Gressel, Neal C. Stewart

Plant Sciences Publications and Other Works

Abstract

Background

One theoretical explanation for the relatively poor performance of Brassica rapa (weed) × Brassica napus (crop) transgenic hybrids suggests that hybridization imparts a negative genetic load. Consequently, in hybrids genetic load could overshadow any benefits of fitness enhancing transgenes and become the limiting factor in transgenic hybrid persistence. Two types of genetic load were analyzed in this study: random/linkage-derived genetic load, and directly incorporated genetic load using a transgenic mitigation (TM) strategy. In order to measure the effects of random genetic load, hybrid productivity (seed yield and biomass) was correlated with crop- and weed-specific AFLP genomic markers. This …

Abstract

Background

Next-generation sequencing techniques enable several novel transcriptome profiling approaches. Recent studies indicated that digital gene expression profiling based on short sequence tags has superior performance as compared to other transcriptome analysis platforms including microarrays. However, the transcriptomic analysis with tag-based methods often depends on available genome sequence. The use of tag-based methods in species without genome sequence should be complemented by other methods such as cDNA library sequencing. The combination of different next generation sequencing techniques like 454 pyrosequencing and Illumina Genome Analyzer (Solexa) will enable high-throughput and accurate global gene expression profiling in species with limited genome …

Sp290-E-Azalea Lace Bug, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Since its introduction from Japan in the early 1900s, the azalea lace bug has become a destructive pest of azaleas. Although this bug prefers evergreen azalea varieties, it will infest deciduous varieties. Mountain laurel can also become infested.

W229-Interpreting Mehlich 1 And 3 Soil Test Extractant Results For P And K In Tennessee, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The Mehlich 1 and 3 soil test extractants are the most widely used in laboratories of the southern United States today. Tennessee began using the Mehlich 1 extractant in December, 1981. Existing soil test calibration data in Tennessee are based on the Mehlich 1 soil test extractant,1,2 which became available in 1953.

W228 Wood Products Information - Test Of A Sodium Carbonate-Based Mold Control Spray On Wood, The University Of Tennessee Agricultural Extension Service

The sodium carbonate-based solution that we tested did not provide good mold inhibition in a severe, standardized test.

Eliminating the warm, wet conditions that lead to mold remains the best option for preventing the growth on mold on wood.

W208-Vegetable Pests - Colorado Potato Beetle, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The Colorado potato beetle, Leptinotarsa decemlineata (Say), is found throughout most of the United States and Mexico and has been introduced into Europe and parts of Asia. Mexico is considered the center of origin for this pest. The Colorado potato beetle is an important pest of Solanaceous plants. Potato is the preferred host, but this insect pest also will feed on tomato, eggplant, pepper, tobacco, ground cherry, horse-nettle, nightshade, belladonna, thorn apple, henbane, buffalobur and other related plant species.

W206-Vegetable Pests - Pickleworm, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The pickleworm, Diaphania nitidalis (Stoll) (Family Crambidae, previously Pyralidae), is found from Canada into parts of South America, and as far west as Oklahoma and Nebraska. It is an important pest of numerous cucurbits. Summer squash is the preferred host, but it also feeds on cantaloupe, cucumber, pumpkin and winter squash. Late-planted cantaloupes are heavily attacked in some areas.

W207-Vegetable Pests - Melon Aphid, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

The melon aphid, Aphis gossypii Glover, is found throughout most of the temperate, subtropic and tropic regions of the world. Although it is a cosmopolitan species, its origin is unknown. The melon aphid has a wide host range and can feed on watermelon, cucumber, cantaloupe, squash, pumpkin, asparagus, spinach, bean, beet, cowpea, tomato, pepper, eggplant, okra, citrus, cotton, hibiscus and many weeds (such as jimsonweed and pigweed). In the South, cotton is an important host, which explains the use of the second common name, “cotton aphid.”

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.
