                            INSECT CONTROL IN MANGO


     Suggested Schedule for Observation for Pest Control on Bearing Mangoes

(This might be termed an insect pest control program, except that not all
pests will be present each year.  It is important to make careful examinations
of trees for insect pests and apply measures for control only when they are
needed.)

The following insecticides are listed by the EPA as being cleared for use on
mangos:  ethion, malathion, methidathion (Supracide), methomyl (Lannate,
Nudrin), parathion, Bacillus thuringiensis and sulfur.

These materials are sold under numerous trade names and the individual labels
often differ from each other.  In order to find the individual label that has
specific directions for your use, contact the local County Agricultural
Agent's office or local agricultural supply dealers.

Under the FIFRA amendment of 1978 the grower may use a material (insecticide)
that is legal and EPA approved for a pest on a crop for other non-listed pests
as long as the user follows the label directions and rates for the approved
pest.

                          Precautions and Restrictions

Parathion is highly toxic and is not recommended for dooryard mango trees.  It
should be used only by licensed operators.

Oil emulsion sprays may injure trees if applied during a very cold, dry period
or during a hot (90~F) period.

Do not mix sulfur with oil emulsion or use either material within 3 weeks of
the other.

Do not apply parathion within 21 days of harvest.

There is no required waiting period for oil emulsion or sulfur.

Malathion has a residue tolerance of 8 parts per million.

Supracide - use only during postharvest to bloom stage.  Do not exceed 5
applications per season.
\h 1 'False Oleander Scales'

\h 1 'Mealybugs'



                                   Mealybugs

The citrus mealybug may infest fruit and cause irregular spotting.

Control -- Check fruit and, if needed, apply parathion at the rate of 1/2 pint
parathion 4 liquid in 100 gallons water.
\b\v
\h 1 'Scales'

\v
                                     Scales

Several kinds including lesser snow, coconut, pyriform, mango shield,
oleander, acuminate, false oleander scale, Florida wax, Florida red, and
dictyospermum may infest mango.

Control -- Check trees and, if needed, apply one of the following in 100
gallons of water: (a) 1/2 pint of parathion 4 liquid; (b) 2 pints of malathion
57% EC; (c) 1/2 - 1 pint Supracide + 0.5% oil per acre (false oleander scale).
\h 1 'Spider Mites'



                                  Spider Mites

Two kinds including the avocado red mite infest mango.

Control -- Few miticides are registered for use on mango.  Apply sulfur dust,
or spray with sulfur using 10 pounds of wettable sulfur per 100 gallons of
water or 2 pints of malathion 57% EC (per 100 gallons of water).

  (May become abundant and cause defoliation; make observations during summer
   and fall for any developing infestation.)

parathion (Drexel)**            8 EC           3 oz                   21

  (Parathion, when used properly, has shown over the years to exhibit
   reduction of scales and mealybugs.)
