How Is Cobalt-60 Used In Pest Control?

Gamma radiation from Cobalt-60 will sterilize the insects before they are released to mate normal, unsterilized pepper weevils in greenhouses. “We will only release pepper weevils that have all the attributes of normal, unsterilized weevils, except that they are sterile,” said Scott-Dupree.

What isotopes are used in pest control?

The most common radioisotopes used are tritium, 14carbon, 32phosphorus, 35sulphur and 36chlorine. Stable isotopes are becoming increasingly important in pesticide research, particularly 13carbon, 15nitrogen and 18oxygen.

How is cobalt-60 used?

What is it used for? Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.

What are three types of chemical pest control?

Types of Pesticides

• Algaecides are used for killing and/or slowing the growth of algae.
• Desiccants are used to dry up living plant tissues.
• Defoliants cause plants to drop their leaves.
• Miticides control mites that feed on plants and animals.
• Ovicides are used to control eggs of insects and mites.

What element is used as a pesticide?

Chlorine is the element which is used in manufacture of insecticide and pesticide because it causes severe toxicity for insects and pests when sprayed leading to their death.

Can cobalt-60 destroy bacteria?

The gamma irradiation process uses Cobalt 60 radiation to kill microorganisms on a variety of different products in a specially designed cell. Gamma radiation is generated by the decay of the radioisotope Cobalt 60, with the resultant high energy photons being an effective sterilant.

What are 3 important uses of cobalt?

Cobalt is also used to make airbags in automobiles; catalysts for the petroleum and chemical industries; cemented carbides (also called hardmetals) and diamond tools; corrosion- and wear-resistant alloys; drying agents for paints, varnishes, and inks; dyes and pigments; ground coats for porcelain enamels; high-speed

What happens if you touch cobalt-60?

Mishandling of a large industrial source of Co-60 could result in an external exposure large enough to cause skin burns, acute radiation sickness radiation sickness A serious illness that can happen when a person is exposed to very high levels of radiation, usually over a short period of time. or death.

What is the active ingredient in pest control?

When you see active ingredients like bifenthrin, permethrin, cyfluthrin, beta-cyfluthrin, deltamethrin, cypermethrin, and lambda-cyhalothrin—they are pyrethrins or pyrethroids.

What are the 4 types of pest control?

4 Types of Pest Control

• Chemical Pest Control. The chemical method involves uses chemical treatments to deter any kind of pest.
• Biological Pest Control. Biological control involves the use of living organisms to control a pest population.
• Electronic Pest Control.
• Physical Pest Control.

What are the 5 methods of pest control?

• 3.1.1 Physical pest control.
• 3.1.2 Poisoned bait.
• 3.1.3 Fumigation.
• 3.1.4 Sterilization.
• 3.1.5 Insulation.

What is the most popular method of controlling insect pest?

Pesticides. Pesticides are the most common pest control method which can be done by anyone.

What is the first tool in pest management?

Prevention
Prevention is the first tool in pest management because it is the most effective, least expensive, most environmentally friendly solution.

What is the latest pest control method?

3 methods of pest control: Biological pest control, Mechanical pest control, and Poisoned bait.

What are the 7 types of pesticides?

Types of Pesticides

• Insecticides – insects.
• Herbicides – plants.
• Rodenticides – rodents (rats & mice)
• Bactericides – bacteria.
• Fungicides – fungi.
• Larvicides – larvae.

What are chemical methods of controlling pests?

Herbicides are taken up by the leaves or the roots of the weed, causing it to die. Insecticides that, as the name suggests, destroy harmful insects, and then there are acaricides which protect plants from mites. Finally there are nematicides to control nematodes that attack the plants.

Which metal is used as insecticide?

Contact insecticides
These can be inorganic insecticides, which are metals and include the commonly used sulfur, and the less commonly used arsenates, copper and fluorine compounds.

What metal kills the most bacteria?

Copper (Cu)
Copper (Cu) and its alloys have been shown to eradicate a wide range of multidrug‐resistant microbes upon direct contact.

How does cobalt-60 sterilize?

Cobalt-60 is type of ionizing radiation. Gamma rays from a source penetrate the targeted material and knock electrons from orbit. For sterilization applications this has the effect of disrupting DNA, which renders any microorganisms present nonviable.
