Temik 10G aldicarb pesticide has rapidly become bi '6Fthe most
widely used pest-,control materials in the foliage industry.
exists as to the effectiveness of Temik when used explicitly as stat
on the label. However, there is need for clarification on the safe use
of this material in the foliage industry.
Temik is a highly effective systemic material with insecticidal,
miticidal and nematicidal activity. The extremely toxic active ingredient
is impregnated into corn cob granules which are encapsulated to prevent
the release of the active material until they contact moisture. Following
application of the granules to the soil, the soil moisture releases the
active ingredient. The toxic agent is absorbed by the roots and subsequently
translocated to above-ground portions of the plant.
Temik 10G is federally registered on the following potted plants or
plant beds,in commercial greenhouses: chrysanthemum, orchids (Cymbidiums),
Easter lilies, poinsettia, gerbera, carnations, roses and snapdragons.
Insects controlled are: aphids, leaf miners, thrips, spider mites and
whiteflies. Registered uses on commercial field grown and nursery plants
include: roses, dahlias, lilies (bulbs), birch and holly. The same
insects as well as nematodes are the pests controlled according to the
label. The utilization of Temik 10G in Florida is sanctioned by a State
label. In addition to the crops appearing on the Federal label, the following
commercial ornamentals may receive Temik 10G treatments- trees and large
shrubs such as birch, citrus (nursery stock only), deciduous fruit trees
(nursery stock only), fir, larch, maple, oak, palm, pine, spruce, etc., and
foliage plants including small woody shrubs. A complete listing of
ornamental plants and the insects, mites and nematodes controlled on
ornamentals can be found on the Florida label.
The following is a list of IMPORTANT ideas and recommendations for
the use of Temik 10G in the foliage industry:
1. There probably exists no other system of crop culture that demands
as close a physical contact between the employee and his crops as
in the foliage industry. The combination of this close relationship,
Florida's excessively high relative humidity and the careless use of
Temik presents a potentially dangerous situation for the employees
in this industry. Remember, it is moisture, including perspiration,
that releases the toxic ingredient from the granule. In other words,
keep granules of Temik from contacting wet skin. Store and make all
transfers of Temik in areas or on surfaces which are dry.
2. Most people have some fear of becoming contaminated by pesticide
sprays and usually protect themselves when spraying. Unfortunately,
these persons seem to have less respect for granular formulations of
pesticides and often become lax when using them. Temik has been
formulated in a granule at a concentration of active ingredient of
10% to lessen its toxicity; however, such preparations are still
very dangerous and should be treated as such.
3. Temik is a superb pest control agent and is fast becoming indespensible
to the foliage industry. However, Temik will not kill all types of
insects! It is highly effective against aphids, mites, mealybugs,
scales, whiteflies, leafhoppers and thrips. One application should
control aphids for six to eight weeks, but spider mite control may
end after four weeks. Temik has not proven effective against
caterpillars (larvae). Use Temik to control only susceptible insects.
4. The use of a respirator with a dust cartridge, goggles, heavy textured
rubber gloves and boots as well as lone-sleeved outer protective
clothing or apron are recommended when applying Temik. Pants with
cuffs should fit outside of boots to prevent granules from entering
shoes and being trapped in close contact with the skin. Never allow
granules to become lodged in clothing. Gloves should extend several
inches above the wrist and be free from punctures or abrasions. !Tear
protective clothing when filling or cleaning application equipment as
well as during application.
5. Immediately following any application to a few plants or a small area,
wash hands and face thoroughly. After-long exposures, work clothes
should be changed followed by showering and especially washing of
hair. Do not allow contaminated work clothes to accumulate, but
wash as soon as possible.
6. In applying Temik, it is best to use an applicator designed for
granular pesticide application. Such an applicator is less likely
to grind granules and create hazardous dust particles. For pot plants,
standard methods of application include: a teaspoon, a shaker bottle,
a powder loader, or a granular, slow-release fertilizer applicator.
The last three items can be calibrated to deliver the small quantities
necessary and are both faster and safer than a teaspoon. Remember,
a little Temik goes a long way -- one 6-inch pot requires a maximum
dosage of only one-eighth of a teaspoon for 4 to 6 weeks effectiveness.
7. Avoid applying Temik to wet foliage. This creates a distinct hazard
as the toxic ingredient is rapidly released on contact with the moist
foliage. This can result in contamination of clothing and skin of
anyone contacting treated foliage.
8. Do not eat, drink or smoke in an area where Temik is being applied.
9. Following treatment, it is advisable to post the treated areas with
signs cautioning both employees and visitors of the potential danger.
The sign should include the date of treatment.
10. Distribute granules uniformly over entire soil surface of pot, container
or bed. Do Not pile the granules in a heap as this presents a danger
to humans as well as the treated plant. Keep the granules in close
contact with the soil so the toxic ingredient can be rapidly absorbed
by the plant's roots and become effective.
11. Following application, water in Tenik as soon as possible with at least
1/2 inch of water. This assures the movement of the toxic material into
the root zone. Use overhead irrigation to remove any granules lodged in
12. Do Not mix Temik with irrigation water or incorporate into soil prior
to planting. This is extremely dangerous as well as illegal.
13, Following treatment with Temik, do not handle potted plants, soil or
examine roots for at least two weeks. If pots must be moved, use rubber
gloves and other protective clothing. Do not work in soil within four
weeks from date of treatment. Remember, rooted cuttings or potted plants
may not be sold before a four-week waiting period after Temik is applied.
14. Don't use Temik indiscriminately. In areas of recurring pest problems,
attempt to schedule Temik applications at the most appropriate and
effective time for treatment. In stock plantings, a satisfactory time
for treatment might be immediately following cutting of propagation
material. The beds would be more open allowing more uniform distribution
of the granules at the soil surface. Furthermore, the area could he
maintained relatively free of personnel without major inconvenience. To
be on the safe side, wait at least two weeks before taking cuttings
following an application of Temik to stock plants.
15. Keep the granules in the pot or in the bed heing treated. Do not
apply massive amounts of Temik as the excess will often land on walk-ways,
bench sides, etc., and expose personnel to contamination.
16. Attempt to schedule Temik applications at the end of a day, preferably
at the end of a work week or just prior to vacation or holiday periods.
Never use Temik where visitors or untrained personnel will come in
contact with it. If possible, keep personnel entirely out of treated
areas for a minimum of 3-4 days following treatment.
17. Avoid water leaching from Temik treated areas. The quantity of
toxic material in water leaching from a recently treated container
may be harmful. This is especially true where dosages are applied
far in excess of recommended amounts as has been observed in the
foliage industry. Observe where lechate water will run and avoid
contamination of non-target areas, such as walkways and work areas.
18. It would be helpful to appoint one or two individuals who are extremely
reliable and competent as Pesticide Managers. They should be responsible
for and completely familiar with the recommended application procedures
for Temik, as well as all safety information.
19. Immediately after the contents of a Temik container are used, burn or
bury all empty packages at least 18 inches deen in soil isolated from
water, supplies and crops. Stay away from and do not breathe or contact
the smoke while burning containers. Never re-use Temik packages for
20. Spills and exposed granules are a distinct hazard. Cover minor field-spills
immediately with soil. Large spills must be collected and buried as
previously described. Flood exposed indoor areas with a solution
containing one-half pound of lye (sodium hydroxide) per 2 gallons of
water. Allow this solution to be in contact with contaminated areas
for 4 hours or longer. The caustic remains must be removed by rinsing
with fresh water. Remember, wear protective face and body clothing
when cleaning up spills. The Union Carbide Corporation emergency
phone number for assistance with spills is- 304/744-3457 (24 hours).
21. All over-exposures to Temik should be reported at once to a physician
and to the Union Carbide Corporation. First aid procedures and the use
of thesantidote are listed on the product label. Read and remember these
life saving instructions. A copy of the product label should be taken
with the patient to the treating physician. In cases of over-exposure,
advice may be obtained from a member of Union Carbide Corporation's
