Sp290-Z-Commercial Sources Of Predators, Parasitoids & Pathogens, The University Of Tennessee Agricultural Extension Service

Commercial Horticulture

The Agricultural Extension Service receives numerous inquiries for information about where insect predators and parasitoids can be purchased. These insects are intended for use by both homeowners and commercial growers as biological control agents.

Biological control uses beneficial organisms rather than insecticides to reduce insect populations. Almost all insect groups include some benefi cial members. The use of beneficial organisms is particularly important where chemical residues are undesirable. Beneficial organisms can be predators, such as ladybugs, lacewings and praying mantids that feed on other insects. Others, such as some species of nematodes and wasps, including Trichogramma, are parasitoids with …

Pb1728-Weed Management In Annuals, Perennials And Herbaceous Ground Covers: Nursery Production And Professional Landscape Maintenance, The University Of Tennessee Agricultural Extension Service

Commercial Horticulture

Controlling weeds in production or landscape areas can be a burdensome task. The objective of an effective and effi cient weed management program is to achieve the desired level of weed control at an acceptable expense (cost). Labor is very expensive and sometimes unavailable, and may require training and supervision. Management must avoid the laborious task of physically removing weeds whenever possible.

This objective is best achieved by an integration of cultural practices focused on minimizing the introduction of weed seed, followed by preemergence and postemergence herbicides (refer to page 10, Herbicide Types) applied correctly at the optimum time to …

W141-2010 Commercial Vegetable Disease Control Guide, The University Of Tennessee Agricultural Extension Service

Commercial Horticulture

The term plant disease, as used in this publication, refers to a plant problem caused by a pathogen, such as a fungus, bacterium, virus or nematode. Other types of plant problems include disorders, caused by cultural or environmental factors, and pest damage, caused by insects or other animals that feed on or otherwise damage plants. This publication only deals with pathogen control and does not address disorders and pest damage.

W017-Controlling The Environment In Greenhouses Used For Tomato Production, The University Of Tennessee Agricultural Extension Service

Commercial Horticulture

Growing tomatoes in greenhouses allows producers to grow plants at a time when it would be impossible to grow outside because of the weather. The sole purpose of a greenhouse is to maintain an environment that promotes optimum production. Solar energy from the sun provides both sunlight and heat, but growers must provide a system that maintains the optimum growing environment in the greenhouse. To maintain this optimum growing environment, your greenhouse must be equipped with well-designed heating, ventilation and air distribution systems that properly control temperature, carbon dioxide and humidity. This publication explains the importance of carefully managing the …

Pb1618-Growing Media For Greenhouse Production, The University Of Tennessee Agricultural Extension Service

Commercial Horticulture

This publication is one of three in a series that covers the basics of developing a nutritional program for producing container-grown plants in greenhouses. A complete nutrition program encompasses the fertilizers, media and water used. The first publication, Plant Nutrition and Fertilizers for Greenhouse Production (PB 1616), develops background information about plant nutrition and discusses the important characteristics of fertilizers used in greenhouse production.The second publication, Irrigation Water Quality for Greenhouse Production (PB 1617), examines the effect of water quality on a greenhouse nutritional program. This publication, Growing Media for Greenhouse Production, describes the important physical and chemical properties …

Sp341-W-Insects In Grain Bins, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

One of the most common insects in stored grain is the Indian-meal moth, Plodia interpunctella (Hubner). These moths are called “flour moths” in Tennessee because they feed on flour or milled products. In farm grain bins, they prefer broken grains or grains damaged by other pests and seldom attack sound grain kernels. They cause problems by spinning webbings as immature. This causes lower quality in stored grain.

Sp721 Sunflower: An Alternative Crop For Tennessee Producers - Production Guidelines And Tennessee Hybrid Trials, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Tennessee producers are interested in crops that can be grown to diversify and/or complement their current cropping systems that include corn, cotton, soybeans and wheat. There is a growing demand for birdseed, and sunflower is an important component of that feed, either as a sole ingredient or in a blend with other seeds such as millet, corn, sesame, sorghum, wheat and oats. Sunflower oil is used for human consumption and is also a suitable feedstock for biodiesel. An increasing demand for biodiesel will increase the demand for oilseed crops such as sunflower. Thus, there may be increased opportunities for some …

Sp290-K The Hessian Fly In Wheat, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

The Hessian fly is a pest of winter wheat in Tennessee and other wheat-growing states. This pest caused disastrous losses in Tennessee wheat in the mid- 1980s. Later planting of wheat and the use of wheat varieties resistant to Hessian fly minimized economic losses from this pest. In the coming years, potential economic losses from Hessian fly could increase due to the lack of resistance varieties.

In 2009, very little attention was given to Hessian fly infestations. However, there are some varieties with moderate resistance to biotype L Hessian fly. None are completely resistant. Some of the better methods to …

Ethylene Receptors Function As Components Of High-Molecular-Mass Protein Complexes In Arabidopsis, Yi-Feng Chen, Zhiyong Gao, Robert J. Kerriss Iii, Wuyi Wang, Brad M. Binder, G. Eric Schaller

Faculty Publications and Other Works -- Biochemistry, Cellular and Molecular Biology

The gaseous plant hormone ethylene is perceived in Arabidopsis thaliana by a five-member receptor family composed of ETR1, ERS1, ETR2, ERS2, and EIN4. Methodology/Principal Findings

Gel-filtration analysis of ethylene receptors solubilized from Arabidopsis membranes demonstrates that the receptors exist as components of high-molecular-mass protein complexes. The ERS1 protein complex exhibits an ethylene-induced change in size consistent with ligand-mediated nucleation of protein-protein interactions. Deletion analysis supports the participation of multiple domains from ETR1 in formation of the protein complex, and also demonstrates that targeting to and retention of ETR1 at the endoplasmic reticulum only requires the first 147 amino acids of …
