bacterium (plural: bacteria). A single-celled, microscopic, plantlike organism that lacks a nucleus. Most bacteria obtain their nitrogen and energy from organic matter; some bacteria cause plant or animal diseases.
bacterium A single-celled microscopic organism having a cell wall but no chlorophyll. They reproduce by cell division.
balled and burlapped (B&B) A plant dug with soil. The root ball is enclosed with burlap or a synthetic material.
A bacterium which is lethal to some insects and is used as a biological control.

Another bacterium long used for insect control is Bacillus popilliae, which produces the "milky spore" disease of Japanese beetle grubs, a major lawn pest.
The grubs eat this bacterium and when it kills them, more spores are introduced into the dirt. Milky spore may take two to fours years to treat a yard and is most effective when it is applied neighborhood wide.

Use a product like Dipel, which contains the Bacillus thuringiensis or "Bt" bacterium, as a last organic resort. Bt-containing products infect caterpillars and cause them to immediately stop eating your plants, then literally explode.
Disease Cycle: The bacterium overwinters in a high percentage of apple buds, leaf scars, and diseased fruit on the orchard floor. Throughout the growing season, the bacterium can survive as an epiphyte on foliage and fruit in the orchard.
Fire blight, caused by the bacterium Erwinia amylovora, is a serious disease of many ornamental species in the Rosaceae family. Certain varieties of apple, flowering crabapple, pear, pyracantha, and quince are highly susceptible.
Bt, a bacterium, kills caterpillars only. These types of substances, specific for certain pests and used only where the pests are present, allow beneficial insects, like lady beetles and lacewings, to live to do their job.
One of the most serious problems affecting all types of citrus today, greening disease results from the action of a bacterium that's spread by a tiny insect, the Asian citrus psyllid.
One of the major problems that iris borer introduces to the leaves and rhizomes is bacterial soft rot (Pecotobacterium carotovorum). Rhizomes become soft, mushy and have an offensive odor.
BT - Bacillus thuringiensis. A bacterium which will destroy the stomach cells of insects that consume it. It degrades quickly in sunlight so spray early in the evening. This biological insecticides will also kill young butterfly caterpillars.
BT - (Bacillus thuringiensis) A bacterium that causes disease in a variety of pest larvae, but is safe to humans, birds and pets, and plants; marketed under such trade names as BiotrolÒ, DipelÒ, and ThuricideÒ.
Fire blight is caused by the bacterium Erwinia amylovora. In addition to apple and pear, other susceptible plants include quince, Pyracantha (fire thorn), Cotoneaster, mountain ash, hawthorn, and raspberry.
Avoid using sawdust for mulch, as the bacterium that breaks down sawdust will take nitrogen from the soil. When creating a walkway, consider laying down black plastic before adding your crushed rock or stepping stones.
At Cornell University's Boyce Thompson Institute for Plant Research, geneticists are employing a nitrogen fixing bacterium to make fertilizer in sun-powered "factories" on plant stems.
Bacillus thuringiensis (B.t.)-A bacterium that produces a protein crystal that damages the gut of insects (mostly caterpillars), formulations of which are used as insecticides.

Formerly known as the deer tick because adult ticks congregate on deer, the tick nymph probably got the disease bacterium from a white-footed mouse.
You can treat them organically by applying spinosad, which is made from a soil bacterium, Saccharopolyspora spinosa. It's sold as Success, Entrust, and Monterey Garden Insect Spray, and is widely available at nurseries.

This spore is eaten by the Japanese Beetle Grubs and has a bacterium that kills the grubs. Upon killing the grubs even more of the Milky Spore is generated thus helping to kill even more grubs.
